Along, with that they are also found to be living in both fresh and sea water, which makes it able to have more nutritional.But, they are however much smaller in body size as compared to other bacterial life inside the environment.
Why is the archaea domain closer to eukarya than bacteria?
Answer:
Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.
Explanation:
Options for this question are:
They both lack a nucleus and contain cytoplasm. The unique functional adaptations of Archaea are more similar to Eukarya adaptations. They both evolved in the same geological time period. Genetically, the Archaea are more similar to Eukarya than Bacteria. They both have membrane-bound organelles. Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.
The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.

From the following choices, identify those that are the inputs and outputs of the light reactions. (Recall that inputs to chemical reactions are modified over the course of the reaction as they are converted into products. In other words, if something is required for a reaction to occur, and it does not remain in its original form when the reaction is complete, it is an input.)
Drag each item to the appropriate bin. If the item is not an input to or an output from the light reactions, drag it to the "not input or output" bin.
Input: NADP+, ADP, water, light
Output: ATP, NADPH, O2
Not input or output: CO2, G3P, glucose
Answer:
Input: NADP+, ADP, water, light
Output: ATP, NADPH, O2
Not input or output: CO2, G3P, glucose
Explanation:
Photosynthetic process is a unique process undergone by autotrophs like plants in their Chloroplast. It involves two major stages viz: light stage and light-independent stage. The light stage is the stage that requires energy from sunlight in order to occur. It occurs when photons of light (input) from the sun strikes Chlorophyll pigments in the Chloroplast. This ignites the Chlorophyll molecule and makes it excited. The excited state of the chlorophyll molecule releases electrons that split water molecules (input) in a process called PHOTOLYSIS OF WATER, into hydrogen ions, electrons and oxygen.
The hydrogen ions is accepted by the NADP+ (input) molecule and reduces it to NADPH (output). Also, the electron generated creates a proton pump in the thylakoid membrane that powers the phosphorylation of ADP (input) into ATP (output). During the light reaction, specifically, PHOTOLYSIS OF WATER, oxygen gas (output) is given off.
Note that C02, G3P and glucose are neither inputs nor outputs of the light stage. They are rather involved in the next stage of the photosynthetic process, which is light-independent stage or Calvin Cycle.
NADP+, ADP, water, and light all serve as inputs to the light reactions. The light processes produce ATP, NADPH, and oxygen as byproducts. CO2, G3P, and glucose are not input or output in the light processes.
Thus, NADP+, ADP, water, and light are the ingredients for the light reactions. Water serves as an electron source, NADP+ serves as an electron acceptor, ADP is a necessary step in the production of ATP, and light powers the processes.
Chemical energy in the form of ATP, high-energy electron carrier NADPH, and oxygen, a consequence of water splitting, are all products of the light processes. The ensuing dark processes, such the Calvin cycle, which uses ATP and NADPH to turn carbon dioxide (CO2) into glucose, depend on these outputs.

Membranous channel extending inward from muscle fiber membrane
Answer:
The correct answer is- transverse tubules.
Explanation:
Transverse tubules are the membranous channel that extends inward from the muscle cell, these are the actually the addition or extensions of the cell membrane that invade into the center of muscles cells except smooth muscles.
The role of the transverse tubules is to generating the stimulus or signals from the sarcolemma to down in the cell. Sarcolemma are the surface of the cells in muscles.
Thus, the correct answer is - transverse tubules.
The T-tubule is the membranous channel that extends inward from the muscle fiber membrane, allowing the action potential to trigger the release of calcium ions from the Sarcoplasmic Reticulum, which initiates muscle contraction.
Explanation:The membranous channel extending inward from the muscle fiber membrane that you are asking about is known as the T-tubule (transverse tubule). These are periodic invaginations of the sarcolemma that ensure the action potential can travel into the interior of the cell. When an action potential propagates along the sarcolemma, it enters the T-tubules and triggers the opening of calcium channels in the membrane of the adjacent Sarcoplasmic Reticulum (SR). This results in the diffusion of calcium ions (Ca++) into the sarcoplasm, which is key in initiating the contraction of the muscle fiber's contractile units, known as sarcomeres.

If a bacterial cell culture contains 2 cells at time zero, 8 cells one hour later, 32 cells after 2 hours, and 128 cells after 4 hours, then which of the following describes the growth of this culture?
A) g = 0.5 h, v = 5 h^-1
B) g = 0.5 h, v = 2 h^-1
C) g = 2 h, v = 0.5 h^-1
D) g = 1 h, v = 1^-1
Answer:
B
Explanation:
This cell culture is in exponential growth, as every 30 minutes the cell population is doubling. at regular intervals.
The generation time (g) describes is the time interval required for the cells to divide.
generation time (g) = time (in hours)/ number of generations
The total time in hours is 4. And the number of generations is the number of population doublings it takes to get to 128, which is 8 (0, 2, 4, 8, 16, 32, 64, 128)
g = 4/8
g = 0.5
Therefore, the answer is either A or B.
v = the specific growth rate of bacteria, with the units h⁻¹. This corresponds to the number of population doublings per hour. The data shows that the population doubles 2x every hour. Therefore, the answer is B.
It is necessary for the immune system to clearly distinguish foreign cells and proteins from those made by the body.
(a) Explain why this is the case:
Answer: It is necessary for the immune system to clearly distinguish foreign cells and proteins from those made by the body so that the immune system will be able to fight foreign cells and proteins and eliminate them from the body.
Explanation: The ability of the immune system to clearly distinguish foreign cells and proteins from those made by the body helps the body to identify pathogens that invade the body and trigger appropriate immune response to eliminate the foreign cells and proteins.
When the immune system of the body fails to distinguish foreign cells and proteins from those made by the body, the body launches an attack against its cells, that is the immune system triggers an autoimmune response in which attacks are launched against the cells of the body and destroy them. This condition in which the immune system recognizes the cells of the body as non-self and launches an attack against them is known as autoimmunity. Autoimmunity is the major cause of most degenerative diseases such as type I diabetes mellitus.

If we were able to artificially alter the membrane permeability of pacemaker cells so that sodium influx is more rapid, ________. A) threshold is reached more quickly and heart rate would increase B) potassium channels compensate and no change in heart rate would occur C) heart rate would decrease, but blood pressure would rise due to the excess sodium present D) tetanic contraction would occur due to the short absolute refractory period of cardiac muscle
Answer:
A,
Explanation
Increase membrane permeability to rapid sodium influx leads to fast depolarization.With continuous rapid opening now , threshold will be reached onetime.
Hence fast propagation of action potential occurs . since reploarization and refractive period now shortened, due to increase rate of depolarization .Rapid action potential will be propagated and transmitted in the cardiac cells. Leading contraction rapid systolic contraction.
Increase in sodium ion concentration in the cardiac cells leads to retention of fluids( the high solute potential draws water in from surrounding tissues and plasma by osmosis) in the cardiac muscles cells. This leads to increase in blood pressure, and the increasing after load leads to rapid heart rate.
If we were able to artificially alter the membrane permeability of pacemaker cells so that sodium influx is more rapid, the threshold would be reached more quickly and the heart rate would increase. Option A
Explanation:If we were able to artificially alter the membrane permeability of pacemaker cells so that sodium influx is more rapid, threshold is reached more quickly and heart rate would increase.
The membrane potential of pacemaker cells increases as sodium ions diffuse through the always-open sodium ion channels, causing the electrical potential to rise.
This prepotential depolarization mechanism accounts for the auto rhythmic property of cardiac muscle. By increasing the rate of sodium influx, the membrane potential would reach the threshold more rapidly, leading to a faster heart rate.

Interestingly, even though hemophilia in the royal families began in England, they were actually the only one of these four families to NOT be affected by it. If Alice's daughter Alix had accepted a marriage proposal from George V, this may have changed history greatly. If we were to rewrite history, pairing Alix and George V together, what is the probability any of their offspring would have hemophilia?
Answer:
Alice's daughter Alix =X X* George V= XY Progeny are;XX, XY, X*X, X*Y 50 % males would be infected 50% male normal50% female normal, 50 female carrier.Explanation:
Hemophilia is an inherited disease and it follows an X-linked recessive pattern. The genes for hemophilia disease are located on the X chromosome. In males one mutated copy of the chromosome X is sufficient to cause the condition, because male contain only one gene. Female contain XX chromosome, so both the chromosome must have mutated for causing this disease.
According to study of Queen Victoria (1891-1901) of England, Alice's daughter Alix was X linked carrier and George V was normal male,
so if they got married, their children would be
parents genotype X X* XY
progeny
XX, XY, X*X, X*Y
50% males would be infected
50% male normal
50% female normal,
50 female carrier.
The correct probability that any of the offspring of Alix and George V would have hemophilia is [tex]$\frac{1}{2}$[/tex].
Hemophilia is an X-linked recessive disorder. This means that the gene for hemophilia is located on the X chromosome, and a male will have hemophilia if he inherits a single copy of the hemophilia allele (since males have only one X chromosome), while a female will have hemophilia only if she inherits two copies of the hemophilia allele (one from each parent).
Queen Victoria was a carrier of hemophilia, and she passed the gene to some of her descendants. If Alix, who was a carrier (as her mother Alice was a daughter of Queen Victoria), had married George V, their children's chances of inheriting hemophilia would depend on the sex of the child:
- Male offspring (XY) have a 50% chance of inheriting the hemophilia gene from their mother (since they inherit their single X chromosome from their mother). Therefore, male offspring have a 50% chance of having hemophilia.
- Female offspring (XX) have a 50% chance of inheriting the hemophilia gene from their mother. However, they would only have hemophilia if they also inherited a hemophilia gene from their father, which is not mentioned in the question. Assuming George V was not a carrier, the female offspring would not have hemophilia but would have a 50% chance of being carriers.

Answer:
In prokaryotes nucleus is not present so replication transcription and translation takes place in the cytoplasm in the prokaryotes while in eukaryotes replication and translation takes place in the nucleus.
In prokaryotes, transcription and translation are coupled but in eukaryotes, transcription and translation are separated by nucleus and post-transcriptional modification takes place in eukaryotes, not in prokaryotes.
In prokaryotes, ATP synthesis takes place in cell membranes because they do not have mitochondria. Eukaryotes contain mitochondria where ATP synthesis takes place in them.
Tong et al. (1998) used binocular rivalry to test brain responses when the person perceived a house or a face. When the person perceived the face, activity in the _____ increased
Answer:
Parahippocampal place area (PPA)
Explanation:
Binocular rivalry is the visual event that require non-cognitive switching between two images. This happens when a person is being shown two images simultaneously, and is only conscious to one image at a time. That image is said to be dominant and the other suppressed.
PPA is increased because it is this area in the brain that is stimulated by visual segments such as pictures.
Final answer:
When a person perceives a face, the face recognition areas of the brain show increased activity. This activity is specific to faces and is different from the brain regions that process places or houses. Older adults show activity in both regions, which correlates with better memory for associated faces and places.
Explanation:
The study by Tong et al. (1998), which explored brain responses using binocular rivalry, found that when a person perceived a face, there was increased activity in the face recognition areas of the brain. These feature detectors are tuned to respond to particular objects, faces being one of the key stimuli. In contrast, places or houses would activate a different region. This is consistent with findings from fMRI scans and research using transcranial magnetic stimulation (TMS) that disrupting the face recognition areas leads to a temporary inability to recognize faces while still being able to recognize houses, indicating the specificity of these brain regions for processing certain types of visual information.
In essence, the research suggests that in young adults, only the brain region for processing faces is active when a face is perceived, unlike in older adults, where both face and place regions show activity. A resultant effect is that older adults tend to remember faces associated with certain places better, as indicated by a surprise memory test conducted after brain scanning.

Which of the following choices presents the correct order, from fastest to slowest?A. Glucose, oxygen, sodium ions.
B. Glucose, sodium ions, oxygen.
C. Oxygen, glucose, sodium ions.
D. Oxygen, sodium ions, glucose.
E. Sodium ions, glucose, oxygen.
F. Sodium ions, oxygen, glucose.
Answer:
2wdaswdawad
Explanation:
The correct order for substances passing through the lipid bilayer, from the fastest to the slowest, is oxygen, glucose, and then sodium ions (option C). Oxygen diffuses freely, glucose requires some assistance, and sodium ions, being charged, require specialized channels for facilitated diffusion.
The passage of substances through the lipid bilayer of plasma membranes occurs at different rates depending on the nature of the substance. Gases like oxygen (O₂) can easily diffuse across the membrane because they are small and nonpolar. On the other hand, polar substances such as glucose and charged particles like sodium ions cannot readily pass through the nonpolar lipid bilayer without assistance. Sodium ions, in particular, are impeded due to their charge and require special transport proteins to facilitate their movement through the membrane.
Considering these properties, the correct order from fastest to slowest for the passage through the lipid bilayer would be oxygen first, as it diffuses freely due to its non-polarity and small size. Glucose, being a small hydrophilic molecule, would pass through at a much slower rate. And sodium ions, due to their charge, would pass through the slowest as they are unable to move through the lipid bilayer without facilitated diffusion through specialized channels.
Therefore, the correct order from fastest to slowest is:
Oxygen (O₂)GlucoseSodium ionsMatch the definitions with their vocabulary terms.

Answer:
1. Stabilizing selection
2. Directional selection
3. Disruptive selection
Explanation:
Natural selection is a process that is considered the mechanism of evolution. The natural selection selects the species in one of the three ways: directional, stabilizing and disruptive selection.
1. Stabilizing selection- occurs when nature favors the average phenotype of the species and the extreme phenotype of the traits is not favored.
2. Directional selection-takes place when one of the extreme traits of a population of a species favored the most and the allele frequency sifts to that direction.
3. Disruptive selection-occurs when both the extreme traits are favored by nature and the population evolves into two separate populations.

The evolution and later reliance on our ______ system has been suggested as the reason why humans use pheromones less than other mammals as sexual cues.
Answer: Reproductive system
Explanation: the reproductive system in humans which is a complex system that consists of sex organs that work together for the purpose of reproduction. This system has taken over the use of pheromomes in human and some other mammals as sexual cues.
Humans use pheromones less than other mammals as sexual cues due to the evolution and reliance on our olfactory system. Though humans still respond to certain pheromones the prominence of our visual and auditory systems and the complexity of our behaviors have reduced our reliance on them. The role of pheromones in human interaction is a subject of ongoing research.
Explanation:The human sensory system referred to in the question is the olfactory system. Pheromones are a type of secreted chemical signal primarily used by many animal species to influence behavior, including attracting the opposite se issuing alarms, or marking food trails. In humans, however, the prominence of other sensory systems, particularly the visual and auditory systems, and the complexity of our behaviors reduce our reliance on pheromones.
Although humans are still thought to respond to certain pheromones, such as axillary steroids, our response is considered less significant compared to many other mammals. This is essentially due to our sophisticated olfactory system's evolution and our greater dependency on it. The less obvious role of pheromones in human-to-human communication continues to be a subject of scientific research.
In context, our evolution and increasing reliance on the olfactory system, which processes complex scents and aromas, has likely influenced humans to use pheromones less as sexual cues compared to other mammals. This shift towards olfaction and away from pheromone-based communication is a fascinating aspect of both biological and sociological studies of human interaction.
