Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other?

A.One chromosome from each pair randomly passes to the sex cells during meiosis and leads to differences between the siblings.

B.One chromosome from each pair randomly passes to the sex cells during fertilization and leads to differences between the siblings.

C.Mutations occur during meiosis and lead to differences between the siblings.

D.Mutations occur during fertilization and lead to differences between the siblings.

Answers

Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.

Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.

Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.

During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.

(T/F)

Answers

1. True. Both lysogenic and lytic cycle cause the host cell to burst and release new viruses. The difference is the lysogenic cycle has the viral dna insert into the host dna then a period of dormancy before creating viral proteins. 2.true. The spot test method can be used to give you a yes or no (positive or negative) to the presence of bacteriophages but it does not tell you a quantity so it is qualitative information.

Answers

Answer:

Explanation:

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?

Answers

Answer:

There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Why is it that dominant diseases are not as common as recessive ones?

Answers

Answer:

Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?

A. Biome
B. Community
C. Ecosystem
D. Habitat

Answers

Answer:

habitat

Explanation:

The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.

What is a habitat?

A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.

Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.

So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of interacting biotic and abiotic factors in an area

Thus, the correct option is D. Habitat.

An area that has been sampled to have a large population of organisms is

regarded as having a high biodiversity.

Biodiversity is defined as the condition in which areas have a high amount

of plant and animal species present there. Any place with a large population

population of organisms have low biodiversity.

The stated facts therefore makes an area that has been sampled to have a

1. What is the major source of energy for the brain

The major source of energy for the brain is glucose. Metabolism of glucose provides energy to the brain.

What is the brain?

The brain is a body part that operates the various functions of the body. It is present in the head of the body. It is divided into two parts, the left brain, and the right brain.

Energy is something that is produced by the metabolism of food. Energy7 is required to carry out all the processes of the body. To walk, run, work, eat, everything requires energy.

The main source of the energy in animals and plants is glucose. The food we eat converts into energy by the process of respiration. The energy is transported into all parts of the body by blood circulation.

If sin = a/b then prove that (sec + tan ) = b+a/b-a help me plswords from the video:What do fireworks, a fried egg, and a rusting vehicle have in common? They all involve chemical reactions. If two or more elements or chemical compounds come into contact with one another and there is enough energy present, a chemical change may take place.When a substance undergoes a chemical change, the chemical structure of that substance is altered. A chemical change can also be called a chemical reaction. During a chemical reaction a new substance is formed.Observe the chemical reaction between bromine and aluminum. Pieces of aluminum are cut from a strip of foil and added to liquid bromine. At first there is no reaction because of the protective oxide coating on the aluminum. But soon an exothermic reaction between bromine and aluminum causes brown fumes of bromine to be given off. But as a new substance, aluminum bromide is produced. White smoke is produced.The resulting residue is also aluminum bromide. When two compounds or molecules react together to form new substances, they are called reactants. They new substances created plus any resulting ash, water vapor, or carbon dioxide are called products, because they are produced by the reaction.Some chemical reactions, such as the explosion of fireworks, can happen very fastin less than a second.Others, like the rusting of a car, might take years. It is important to carefully examine chemical reactions because there are many ways substances can be changed without a chemical reaction taking place.Changes of state, for example, from a solid to a liquid or from a liquid to a gas, always involve a physical change rather than a chemical one. Melting sulfur is a good example. When solid sulfur is heated to 120 degrees Celsius it melts and first forms a pale yellow liquid.In this form the atoms are covalently bonded and the liquid can flow easily. However, heated up beyond 150 degrees Celsius, the result is a dark red liquid that is over 2,000 times stickier. The sulfur may have changed physically but it's still sulfur.No chemical reaction has taken place. Most of the time changes of state can be reversed by either adding or taking away heat. When water is boiled, for example, water vapor molecules are released in the process.If you captured all the vapor molecules in a container they would reform again as water droplets once the vapor cooled. When a chemical change occurs it is more difficult to revert the substance back to its original state. Members of the same culture generally share a common A. political ideology. B. amount of income.
