I need an example of Bacteria, Archaea, and Eukarya.
Answer:
Both Bacteria and Archaea are prokaryotes, single-celled microorganisms with no nuclei, and Eukarya includes us and all other animals, plants, fungi, and single-celled protists – all organisms whose cells have nuclei to enclose their DNA apart from the rest of the cell
Bacteria, Archaea, and Eukarya are three domains of life. Bacteria are prokaryotic organisms, while archaea are also prokaryotic but have unique characteristics.
Explanation:Eukarya include plants, animals, fungi, and protists, and are characterized by having a nucleus and membrane-bound organelles.
Bacteria: An example of bacteria is E. coli, which is commonly found in the intestines of humans and other animals. Bacteria are prokaryotic organisms that lack a nucleus and membrane-bound organelles.
Archaea: Methanogens are an example of archaea. They are found in environments such as swamps and produce methane gas as a byproduct of their metabolism. Archaea are also prokaryotic organisms, but they have unique genetic and molecular characteristics.
Eukarya: Plants, animals, fungi, and protists all belong to the domain Eukarya. An example of a eukaryotic organism is a rose plant. Eukarya have a nucleus and membrane-bound organelles.

Explanation:
The starting cell must duplicate its Chromosomes in interphase before mitosis can being? Does this change the number of chromosomes? Chromatids? both? how many of each would you expect in a human cell after interphase
Answer:
The correct answer is both.
Explanation:
Each chromosome is made up of a pair of sister chromatids which remain attached to each other at the centromere.During DNA replication the DNA duplicates, which means that if initially in the parent cell 'n' chromosomes were present then, after duplication, the number of chromosomes in the cell will be '2n'.As mentioned above, each chromosome has a pair of sister chromatids, that is, two chromatids per chromosome. So, 'n' chromosomes will have '2n' chromatids. Hence, '2n' chromosomes will have '4n' chromatids.In a parent cell,Before duplication, number of chromosome = n, number of chromatid = 2n.After duplication, number of chromosome = 2n, number of chromatid = 4n.The cell cycle proceeds as, G0, G1, S, G2, M.G0 represents the interphase. It occurs before replication or duplication of the chromosomes, which occurs in the S phase.So, in G0 phase, the chromosome number is 'n' and chromatid number is '2n'.DNA REPLICATION:
DNA replication is the process by which the DNA of a cell is doubled prior to cellular division. DNA replication occurs at the S-phase of the interphase stage of mitosis and meiosis. The DNA is doubled and represented by an increase in number of chromatids in each cell. The chromosome number does not change from 46 in a diploid cell (2n). However, the number of chromatid changes from 46 to 92 in each cell. After interphase stage, two chromatids each is expected to be present in each human cell.Learn more at: https://brainly.com/question/11554563?referrer=searchResults
Compare headlines 4 and 5. Why is there a difference in the two headlines even when they outline the same scientific research?
Answer:
First, let's add the missing piece- the article
"Well, we haven’t read the articles yet, but I have their titles here. You can read them,” Alana said as she handed a paper to her mother with the following list:
1. Long-Term Cell Phone Use Spurs Tumor Growth
2. Mobile Phone Use and Acoustic Neuroma
3. Study Links Mobile Phones, Benign Tumors
4. Cell Phone-Tumor Link Found?
5.Study Indicates Mobile Phones Increase Tumor Risk
“Now I’m even more confused. Do cell phones cause cancer or not? Can I use mine or not?” asked Alisa impatiently.
“In my next class we’re going to read the articles, so I will tell you everything then,” concluded her sister.
Then the Answer to our question:
Both headlines 4 and 5 outline the exact same way, with little or no difference in the headline structure. On a closer look, we can infer that scientific research 4 looks less definite in a risk being found research. Unlike 5 which looks more definite in combining mobile phones with acoustic neuroma.

Can the classification system change? If so, provide an example of a way it has changed in the past.
Answer:
Yes, classification system can change with time due to the improved understanding of organisms around us and majorly due to evolution.
Explanation:
Carolus linnaeus devised various rules and factors to classify and name both plants and animals. This was the first system of classification.But, with the huge discoveries of scientific knowledge about these beings this system of classical taxonomy has to be revised again and again to incorporate new found information.One such example is the discovery of microscope which lead to the discovery of microscopic forms of life.And, this system of classification had to be changed.Choose the answer that best describes gravity.
Question 2 options:
Gravity only works between planets.
Gravity is a contact force that holds objects down on Earth.
Gravity is a contact force that holds the Moon in orbit around Earth.
Gravity is a non-contact force that holds the Moon in orbit around Earth.
"Gravity is a contact force that holds objects down on Earth" best describes gravity.
Answer: Option B
Explanation:
Gravity is the force which attracts two bodies one to the other. It is the force which causes objects in the air to fall to the ground and keeps the planets around the sun in their orbit. The greater an object's mass, the greater its gravitational power.
Gravity declines with elevation, near the Surface of the earth (sea level), so that at one-half of the Earth's radius, linear extrapolation will give zero gravity. The gravity of Planet originates from all of its mass. All its mass causes the whole mass in one's body a collective gravitational pull on.

O
D. The moose would be more able to protect its offspring.
SUBMIT
The answers are.
A. The moose would be more able to avoid predators.
C. The moose would be more able to chase and catch prey.
Explanation:
This moose population can use their speed to protect themself from the predators, but only protecting themself from predators won’t help them for their survival. They need food to live. Speed will help them to chase and catch the pray also. Since the population of moose in the Yellowstone National Park is less for them, it is very difficult to protect their territory by using their speed. They can use their speed to chase their prey. Maybe while chasing they ended up facing their predators, but they can use their speed to escape from them. Later, this will help them to make offspring also. Moose will be able to protect their offspring by running, but they should give food to the offspring also to survive.Answer:

In the following reaction, if you wanted to produce more hydrochloric acid (HCl2), what would you do? 4HCl + O2 arrows both ways 2H2O + Cl2
Answer:
First answer : equilibrium shift towards the formation of the reactants
Second answer : equilibrium shift towards the formation of products
Third answer : need to add more H2O.
Explanation:
In a reversible chemical reaction, the shift of equilibrium of the reaction towards the production of products or reactants is dependent on the abundance of reactants or products. As in the first question, if the products available are more (C) than the reactants, then the equilibrium of the reaction would shift towards the formation of the reactants (A and B). As in second question, If reactants available are more (heat addition) than that of products, then the equilibrium of the reaction would shift towards the formation of products (D). As in the third question, we want to generate more HCL, which is the reactant, so we need to increase the amount of product, so we need to add more H2O.
How many nadh molecules are created from the pyruvate molecules that enter the Krebs cycle?
Answer: Three molecules of NADH is produced from every molecule of pyruvate that enters the Krebs cycle.
Explanation: Pyruvate produced from glycolysis is broken down to Acetyl CoA which then enters the Krebs cycle. In Krebs cycle, each molecule of acetyl CoA yields one molecule of GTP (ATP), one molecule of FADH2 and three molecules of NADH. The main purpose of Krebs cycle is to generate NADH needed in the cells. Krebs cycle is a series of eight enzyme catalyzed reactions which oxidizes the Acetyl CoA produced from pyruvate. The NADH molecules are produced by dehydrogenase enzymes:
1). Isocitrate dehydrogenase which converts isocitrate to alpha ketoglutarate.
2). Alpha ketoglutarate dehydrogenase which converts alpha ketoglutarate to succinyl CoA.
3). Malate dehydrogenase which converts malate to oxaloacete.
Devise a scheme to prepare 10^-6 dilution on a plate using the least number of sterile water dilution tubes.
Answer:
The serial dilution can be done by half- logarithmic dilution method.Explanation:
The following step explains the way to obtain [tex]\frac{1}{10^6}[/tex] dilution. The volumes taken are arbitrary.Take 1 micro-litre (ul) of the concentrated solution in a dilution tube. Add water to it till the total volume becomes 10 ml. Here the solution formed is [tex]\frac{1}{10^4}[/tex] diluted.Take 100 micro-litre(ul) of [tex]\frac{1}{10^4}[/tex] diluted solution to another tube and add 9900 micro-litre(ul) of water to it. Here the solution formed is [tex]\frac{1}{10^6}[/tex] diluted.To prepare a 10^-6 dilution with the least number of sterile water tubes, perform a series of serial dilutions, starting with a 1:10 dilution and repeatedly diluting the resulting solution by the same ratio until the desired 10^-6 dilution is reached.
Explanation:
1. Make a 1:10 dilution by taking 1 unit of A (such as 1 ml) and adding it to 9 units of sterile water. This will give you a 10^-1 dilution (B).
2. Repeat this process with B to get the 10^-2 dilution (C).
3. Continue this process until you reach the desired 10^-6 dilution.
This method ensures that you are using the least number of tubes by diluting sequentially rather than trying to make the 10^-6 dilution directly, which would require a tremendous amount of sterile water and be significantly less accurate.

Hey, biology help needed. All questions please. Extra points!!!!
Answer:
13. C
14. C
15. B
16. B
17. B
Explanation:
13. Having a long neck is a selective advantage for giraffes. Their long necks make them better suited to reaching food supply at the top of trees, improving their fitness and chances of reaching reproductive age and passing on traits to the next generation. This is how natural selection acts on these traits meaning that over time, giraffes evolve a long neck.
14. The variation in the mice tail length has shifted over time, which suggests that the frequency of the alleles that control tail length has changed. This is clear when you look at the peak of the graph, which has shifted towards longer tail lengths. This suggests alleles coding for longer tail lengths are becoming more common, with the loss of shorter tail lengths
15. If a mutation spontaneously appears in the rabbit genome that makes them resistant to the virus, then they are much more likely to survive than other members of their population. This selective advantage means they are more likely to reach sexual maturity and reproduce, passing the mutation on to the next generation, where they also will benefit. Rabbits breed a lot and quickly, so natural can happen reasonably quickly in these populations, meaning the numbers of resistant rabbits will rise.
16. A vestigial structure is one that is now redundant. That means that the organism no longer uses it. These remain because there are no real selective pressures acting on them that would cause their disappearance to accelerate. Instead, they remain. These bones indicate that at one point, whale populations used to have additional limbs, suggesting they evolved from four legged animals.
17. Changes in the genetic code of an organism can sometimes produce effects such as changes to protein structure, composition, and amount. These can have changes on a much larger scale such as in the structure of forelimbs. Beneficial changes will be positively acted on by natural selection. For example, a bat could develop a stronger wing structure for rapid flying, where as the whale forelimbs are very large to make them powerful in the water. Natural selection can only act on these changes if they are heritable, meaning they have to have changed in the DNA. Any physical changes not present in the DNA will not be passed on to the next generation or undergo evolution.

Explanation:
The compounds are lipids
Organic compounds in nature may be large chains of monomers forming biological macromolecules which perform many essential functions in the body. Nucleic acids, sugars, proteins and lipids may be included. These are organic molecules, containing ringed or long-chain Carbons bound to oxygen (O), hydrogen (H), nitrogen (N), and phosphorus (P) elements; they are contained in important organic biomolecules, including proteins, nucleic acids, lipids, and carbohydrates.
Lipids serve as energy storage and chemical messengers for oils, saturated and unsaturated fatty acids with double bonds and waxes and steroids. Nevertheless, lipids consist of fatty acids and glycerol; they do not comprise a fixed set of monomers, and they are not polymers, unlike the other biological macromolecules. Such non-polar macromolecules can offer hydrophilic and hydrophobic properties through the arrangement of hydrophobic heads and hydrophobic fatty acid tails. Specific makeup: C, H, O; non-polar-a triple condensation reaction creates molecules bound to three long-chain carboxylic acids from a single hydroxyl (OH) alcohol.

In order for ground water to enter a well, the well must be deeper than the water
table.
true or false
True
Explanation:
To get water in the well, the depth of the well should be deeper than the water table in that region.The water table distance from the surface is varied with the locality. It depends on the availability of the source like rain, soil type which means that the soil which has a higher percolation rate will have a high water table, etc. Hence, when we did a well and the depth should be deeper than the water table for it gets water for a long time even in summers.the genotype for people who do not taste PTC?
Answer:
Virtually all non-tasters (dd) cannot taste PTC, while homozygous tasters (TT) occasionally report an inability or weak ability to taste the chemical. The heterozygous genotype (Tt) has the "leakiest" phenotype as reduced or absent tasting ability is relatively common. This is formally called a heterozygous effect.
Explanation:
The genotype for people who cannot taste PTC is 'tt', meaning they have two recessive alleles for the TAS2R38 gene. This genetic makeup results in a lack of sensitivity to the bitter chemical PTC, distinguishing 'non-tasters' from 'tasters' and 'supertasters' who may possess at least one 'T' allele.
The genotype for people who cannot taste PTC is 'tt'. This means they have two copies of the recessive allele. PTC, or phenylthiocarbamide, taste sensitivity is an inherited trait determined by the presence of a specific gene, TAS2R38. Individuals who can taste PTC may have the genotypes 'TT' (homozygous dominant) or 'Tt' (heterozygous) whereas only the 'tt' genotype leads to an inability to taste PTC. The TAS2R38 gene contains single nucleotide polymorphisms (SNPs) that influence the structure of a taste receptor protein on the tongue, affecting the ability to detect the bitter taste of PTC.
Supertasters have an enhanced sense of taste, often because of a higher number of taste buds or sensitivity to certain compounds, and may have a genotype leading to a heightened response to PTC and similar compounds. The genetic variation in the TAS2R38 gene is a prime example of how taste preferences and sensitivities can be affected by our genetic makeup.
What does a line in between two individuals represent?
Answer:
In a pedigree chart, the line which is horizontal shows the parents which mated and produced the children which are represented in the vertical lines below them.
A pedigree chart can be described as a diagram which illustrated the sequence of ancestors of an individual. Often, a pedigree chart is used to look for genetic traits or genetic disorders which might run in the family history. Pedigree charts are important for understanding the probabilities of the offsprings in which a genetic disorder might occur due to family history.

What is true about elements and compounds? A. Elements contain two or more compounds. B. Compounds contain two or more elements. C. Compounds contain atoms; elements do not. D. Elements contain atoms; compounds do not
Answer: B) Compounds contain two or more elements
Explanation:
True about elements and compounds B. Compounds contain two or more elements . Therefore , B. Compounds contain two or more elements is correct .
An element is a substance that consists of only one type of atom.
Each element is defined by the number of protons in the nucleus of its atoms, known as its atomic number.
Elements cannot be broken down into simpler substances by chemical reactions.
A compound, on the other hand, is a substance composed of two or more different elements chemically bonded in fixed proportions.
The atoms in a compound are combined in a specific ratio based on their chemical properties.
Compounds can be broken down into simpler substances (elements or other compounds) through chemical reactions.
For example:
Water (H2O) is a compound made of two different elements, hydrogen and oxygen.
Carbon dioxide (CO2) is a compound made of carbon and oxygen.
So, option B is correct: Compounds contain two or more elements.
