Red eyes (e) in fruit flies are recessive to black eyes (E). If a fruit fly physically expresses red eyes, what is its genotype?
Answer: The genotype of a fruit fly which physically expresses red eye is (ee)
Explanation: The red eyes trait (e) is recessive to black eyes (E) that is, the black eyes trait (E) is dominant over the red eyes trait (e). Therefore, for the red eyes trait to manifest physically the genotype must appear as a homozygous allele (ee)
Kai looks at a photo of herself with her parents. She notices that, while her features are similar to her parents’ features, they do not appear to be identical.
Which explains why this is the case?
Their DNA is made of different codon sequences.
Their DNA is made of four different bases.
Kai inherited more proteins from one parent than the other.
Kai inherited different amino acids from either of her parents.
Answer:
A
Explanation:
Just took the test
The best explanation as to why Kai is not identical to her parents is because their DNA is made of different codon sequences.
When it comes to expressing genes, the information on organisms' DNA sequence is first transcribed as codes into an mRNA. The coded information is then translated as proteins in a process known as protein synthesis.
Thus, for two organisms to be identical, the information on their DNA must be exactly the same. In other words, the codon sequence on their DNAs must be the same. Once there is a variation, different messages would be translated and this will tell as variations on the physical appearances of the organisms.

What happens when hydrochloride is added
Answer:
"Hydrogen gas and iron chloride are produced" happens when hydrochloride is added.
Explanation:
The iron chloride & hydrogen gas (with bubble formation) is generated by adding hydrochloric acid to the iron filings. The iron displaces hydrogen from hydrochloric acid to form iron (II) chloride & hydrogen gas. That is a single displacement reaction.The reaction is given as follows: Fe+2HCl⟶FeCl2 + H2 .
Further to conform that only these products are formed some analysis is done of the resulting solution and gas formed:
A pH measurement demonstrates that the solution becomes less acidic, thus hydrogen ions have been consumed. The addition of silver nitrate results in the formation of a white precipitate indicating that the chloride ions are still present in solution.Describe the structure of a typical bone

Reaction velocity always increases with increase in temperature,
Reaction velocity remains constant with an increase in temperature.
Reaction velocity increases up to a certain temperature before decreasing,
D)
Answer:
The correct description of the relation is reaction velocity always increases with an increase in temperature (option B).
Explanation:
A chemical reaction can be affected by a variety of factors, including the concentration of reactants, pressure and temperature. In the case of temperature, the reaction rate increases depending on the temperature increase.
In a chemical reaction, a temperature -or heat - elevation results in an increase in the speed of motion of each component's particles, while increasing energy and effective shock between them.
Reaction → heat → increased energy → greater effective shocks of particles.
As a result of this, the relationship between reaction velocity and temperature is that at a higher temperature makes a reaction faster.

An ecological pyramid is sometimes used to show both the flow of matter and energy in an ecosystem. The pyramid narrows as matter and energy flow from the bottom to the top. Draw a conclusion about what this pyramid tells you about the energy in this ecosystem.
Answer:
An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms. There is also a pyramid of numbers representing the number of individual organisms at each trophic level. Pyramids of energy are normally upright, but other pyramids can be inverted or take other shapes.
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.
Biomass can be measured by a bomb calorimeter.

Which of the following is a radical?
O
H20
OH
H
Answer:
The correct option is C) OH
Explanation:
In the field of chemistry, radicals can be described as atoms, molecules or ions which have at least one unpaired electron.
The formation of a radical occurs when a single covalent bond breaks so that each of the atoms that had been involved in the formation of the covalent bond can have an unpaired electron. Examples of radicals include OH, NH4+ etc.
Other option, like option B, is not true because a molecule of water does not have any unpaired electrons in its valence shell.

Cheetahs are one example of a population that has very limited genetic variation.
Which of the following groups of animals are most likely to have a limited variety in the genetics of their population?
Question options:
A. animals that have a very large population.
B. animals that live on more than one continent.
C. animals on the endangered species list.
D. animals that live in both hot and cold climates.
Answer:
Animals on the endangered species list.
Explanation:
An endangered species has very limited genetic variation (e.g Cheeta). The population of the cheetah that is already near to extinct is less likely to evolve much in response to the changing environment. The less chances of surviving are because of lesser chances of carrying positive mutations and diverse gene pool development during crossing. Hence, cheeta is an example of a population that has less chance of variation.

How do species adapt to changing environments over time? Explain how evidence from the fossil record and from living species suggests that earth's species are related. List each type of evidence and provide an example of each.
Answer:
Living organisms are adapted to their environment. This means that the way they look, the way they behave, how they are built, or their way of life makes them suited to survive and reproduce in their habitats. For example, giraffes have very long necks so that they can eat tall vegetation, which other animals cannot reach. The eyes of cats are like slits. That makes it possible for the cat's eyes to adjust to both bright light, when the slits are narrow, and to very dim light, when the slits are wide open.
Behavior is also an important adaptation. Animals inherit many kinds of adaptive behavior. In southern Africa there are small animals called meerkats, which live in large colonies. The meerkats take turns standing on their hind legs, looking up at the sky to spot birds of prey. Meanwhile, the meerkats in the rest of the colony go about their lives. You can probably think of many other features of body or behavior that help animals to lead a successful life.
In biology, an ecological niche refers to the overall role of a species in its environment. Most environments have many niches. If a niche is "empty" (no organisms are occupying it), new species are likely to evolve to occupy it. This happens by the process of natural selection.
Many fossils of different kinds of horses have been discovered, and paleontologists think that the earliest ancestor of the modern horse lived in North America more than 50 million years ago. This animal was a small padded-foot forest animal about the size of a dog. If you saw one next to a modern horse, you might not even think the two were related! As time passed, the climate of North America became drier, and the vast forests started to shrink. Grasses were evolving, and the amount grassland was increasing. Horses adapted to fill this new grassland niche. They grew taller, and their legs and feet became better adapted to sprinting in the open grasslands. Their eyes also adapted to be further back on their heads to help them to see more of the area around them. Each of these adaptations helped the evolving grassland horses to avoid predators. Their teeth also changed to be better adapted to grinding tough grassland vegetation.
Explanation:
Fossils are the preserved remains of living things. Different species show adaptations for the changing environments. Evidence from the fossil records show how species have evolved on this planet.
What are Fossils?Fossils are the preserved remains of living things such as plants and animals whose the bodies which were buried in different sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any of the preserved traces of life which is typically more than 10, 000 years old.
Species have different adaptations for the changing environments. For example, some types of species use mimicry or camouflage, while the other changes include their location or their eating habits. Evidence from the fossil records also suggest that different species have evolved over time. It also suggests that some of the earth's species are related with each other.

Lionfish, indigenous to the Indian Ocean, have been found in the Atlantic Ocean since their accidental release in the late 20th Century. These fish feed on the same species as local snapper and grouper. They can also impact coral reef ecosystems by consuming herbivores, which keep the algae populations in check. Which statement explains why the lionfish populations continue to increase in the Atlantic and the impacts of the lionfish on marine ecosystems continue to be observed?
A) Lionfish have no natural predators in the Atlantic, so there is a lack of population control for these fish.
B) Lionfish have a narrow range of temperature tolerance and salinity, so they only reproduce exponentially in the Atlantic.
C) Lionfish have symbiotic relationships with coral reef species that increase the populations of native and invasive species.
D) Lionfish migrate to the aphotic zone of the ocean to spawn, which has no light and reduces the visibility of the eggs for parasites.
Answer:
The correct option is A) Lionfish have no natural predators in the Atlantic, so there is a lack of population control for these fish.
Explanation:
The description in the question tells that the lionfish is not a native in the Atlantic ocean. As a result, it does not have many predators in that ocean to keep a balance on the population of the lionfish species. As a result, the population of the lionfish increases as it has an abundant supply of preys but not enough predators which will feed on it. Hence, the population of the lionfish continues to increase in the Atlantic.
Answer: the correct answer is below
Lionfish are native to the Indo-Pacific region. However, a hurricane caused six fish from an aquarium to accidentally be swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to rapidly increase in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of ocean. These fish have predators such as sharks and scorpion fish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food. Their one predator is humans, who have recently started fishing them for food. In the Atlantic Ocean, algae and seaweed are producers. Small fish, crabs, and other crustaceans make up the first and secondary consumers. Sharks and orcas are some of the larger predators, which are also consumers. Bacteria and fungi are the decomposers that break down food. Lionfish are consumers because they eat fish and small crustaceans.

Mitochondria is well know as the power house of cells and it is performs cellular respiration.It gets originated from a bacteria known as "Alphaproteobacteria". They are nothing but anoxygenic phototropic bacteria with aerobic nature.Aerobic bacteria are nothing but the bacteria that can grow or survive in oxygen filled environment or oxygenated environment and can't survive in the absence of oxygen.Various studies also have stated that mitochondria got originated from such planktonic marine bacteria known as "alphaproteobacterial" which is an aerobic bacteria and hence we can conclude option A as right answer.
No stripe on the head (H) is dominant, a black stripe on the head is recessive. If dad's genotype is Hh, what are the odds that the offspring will have a stripe?
Select one:
a. 50%
b. 100%
c. 0%
d. 25%
The chance of the offsprings with stripe on head is 50%.
Option A.
Explanation:Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.
So the genotype of the father which is given as Hh. He is heterozygous.
The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.
So the gametes from father is H and h. Whereas the gametes from mother is only h.
So the genotype of the offsprings are Hh and hh as 50% each.
So the probability of the offspring being striped head is 50%.
What is a process that can occur in ocean due to the uptake of extra atmospheric co2
Ocean acidification is a process that can occur in ocean due to the uptake of extra atmospheric [tex]Co_2[/tex]
Explanation:
Ocean acidification is happening since abundance carbon dioxide [tex](Co_2)[/tex] in the environment is being caught up in the outside of the sea at an expanding rate. Regularly, sea water is less acidic than freshwater. As such the sea assimilates increasingly more carbon dioxide from the climate, it turns out to be progressively acidic.
This process of [tex](Co_2)[/tex] brings about more hydrogen particles, which builds the causticity of the sea. So this Ocean acidification is a procedure that can happen in the sea because of the take-up of extra biometric.

An occluded front moves over farmland that has been experiencing drought conditions.
Which change in weather will this front likely bring?
an extended period of rain
more dry air and sunny skies
gray skies, but no rain
violent, short-lived thunderstorms
Answer:
This honestly depends on whether it is a cold or warm occuluded front. Cold occluded fronts bring violent storms like hail and thunderstorms and have also caused tornadoes. Warm occluded fronts typically produce light rain.
Best answer is : An extended period of rain
Explanation:
Occluded Front Forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Can bring strong winds and heavy precipitation.
translate dna into tRNA
Answer AND Explanation:
Transcription is the process of creating a complementary RNA copy of a sequence of DNA. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as a complementary language that enzymes can convert back and forth from DNA to RNA. During transcription, a DNA sequence is read by RNA polymerase, which produces a complementary, antiparallel RNA strand. Unlike DNA replication, transcription results in an RNA complement that substitutes the RNA uracil (U) in all instances where the DNA thymine (T) would have occurred. Transcription is the first step in gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcript. Some transcripts are used as structural or regulatory RNAs, and others encode one or more proteins. If the transcribed gene encodes a protein, the result of transcription is messenger RNA (mRNA), which will then be used to create that protein in the process of translation.

Since their time, many new discoveries have been made supporting the theory, including new knowledge of genetics and the chemical process of heritability. But since the biological theory of evolution depends on scientific observations, which scientific finding, if it was ever made, would force scientists to radically change the theory? A. if a very famous scientist decided she did not like the theory B. if modern animal fossils were ever found in a very ancient geologic period C. if an animal's circulatory system was shown to be very complex D. if a very ancient species of animal was found to still be alive today
If modern animal fossils were ever found in a very ancient geologic period, it would have changed the whole evolutionary theories.
Option B.
Explanation:Evolution as an event, is very slow and gradually progressive movement. It took millions of years for the unicellular bacteria to evolve and finally make the modern day humans. But the process isn't a haphazard and the evolution processes are well understood by humans. A scientist can clarify how the cell systems became complex to eukaryotic cells, the tissues began to develop, and then the organs and the organ system. The systems like circulatory system, nervous system, muscles, everything slowly grew to evolve animals into a superior one. This is the theory in present days and this is supported by Fossils and different other proofs.
But if one day, a fossil is found which is actually the fossil of a modern animal in very ancient time, its not collaborative with the theories. Modern day animals are born as a result of huge evolutions and presence of them in very ancient times is impossible. So this finding can wipe out present day theories of evolution.
Explain how scientists would classify an extinct species such as a dinosaur. In your answer , discuss some of the difficulties that he or she may face
Answer:
To classify an extinct species, the scientist might have to look for any kinds of clues he can look for in the fossil record. The scientist might look for the evolutionary traits and predict that the dinosaur has closest resemblance to which other types of dinosaurs. In this way, he can place the organisms with similar characteristics or features in the same group. Also, studying the time period in which the dinosaur may heave existed may also help to classify the dinosaur.
Classifying extinct species is difficult because one cannot determine the exact features pf the extinct species which help to predict the groups in which the organism is to be placed.
