How does artificial selection affect variation within a species when a specific trait continues to be bred?
It reduces the amount of variation.
It increases the amount of variation.
It has no impact on the amount of variation.
It causes variation to fluctuate with each generation.
The amount of variation is reduced when a specific trait continues to be bred.
What is artificial selection?Artificial selection is the process in which organisms are chosen by human for the breeding purpose in order to get the desired characteristics.

The diagram below represents one way an enzyme can be inhibited (stopped).
Which statement explains the effect of an inhibitor on an enzyme?
The substrate will not be able to attach to the enzyme's active site.
O The enzyme will likely be attacked by immune cells.
Answer:
The answer is The substrate will not be able to attach to the enzyme's active site.
Because the function of inhibitors is to block the enzyme's activity
Explanation:
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT
The substrate will not be able to attach to the enzyme's active site. So the correct option is A.
What is an enzyme inhibitor?The inhibition is carried out by inhibitors that do not advance the product's development. The inhibitors may affect the enzyme as well as the substrate. Enzyme inhibition is the term used to describe the cessation of enzyme activity.
These enzyme inhibitors can bind to active regions and prevent further action by stopping it. Both reversible and irreversible forms of binding are possible. The ability of an inhibitor to block an enzyme may be irreversible or reversible depending on its unique function. Enzyme inhibitors can block the binding site, which reduces the enzyme's catalytic activity by preventing the substrate from binding to the active site.
Reversible inhibitors bind to enzymes by non-covalent interactions such as ionic bonds, hydrogen bonds, and hydrophobic contacts. Reversible inhibitors do not conduct chemical reactions when they are linked to an enzyme and are quickly removed by dilution or dialysis.
However, irreversible inhibitors usually covalently change an enzyme, making it impossible to reverse inhibition.
Therefore, the correct option is A.

A female mosquito can produce 50-500 offspring in a two-week period of time. This rapid reproduction can also result in fast
evolution for this small insect species. For example, pesticide resistance occurs rapidly in insects, including mosquitos. Insecticides
that were once effective at eradicating mosquito populations are no longer effective. Which component of natural selection is
Likely playing a role in this rapid evolution for mosquitos?
A)
Mosquitoes pass only advantageous traits on to their offspring during
reproduction. This ensures increased survival and reproduction.
B)
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
Mosquitoes that learn to avoid pesticide exposure can pass that
information on to offspring. This increases the survival of those offspring
as well.
D)
Mosquitos have the ability to detect areas with high pesticide loads and
can avoid those areas. This allows mosquitos to survive and reproduce with
more success.
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
What are mosquitoes?Mosquitoes are ectoparasites, which live on the blood of different animals.
They suck blood from the skin of animals and leave red spots, which are itchy.
Mosquitoes lay their eggs in water and live in dirty, moist, dark places.
They are also responsible to cause malaria in humans.

Explanation:
It's pretty simple really, just find the Benefit. Pollution is definitely a harmful effect, disease is also not a benefit, and depletion of fish population is bad, so easing demand on commercial fisheries is the answer

HELP, define genetic engineering and Describe how DNA is modified for use in genetic engineering.
Answer:
Genetic engineering is deliberate modification of genome to gain desired traits.
The main steps of genetic engineering:
Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.
