1.In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

2.Every organism has a unique ecosystem within which it lives. ... All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.

3.Adaptations are inheritable characteristics that increase an organism's ability to survive and reproduce in an environment. Adaptations can help an organism find food and water, protect itself, or manage in extreme

4.Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. ... Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.

5.Within a population of organisms are genes coding for a certain number of traits. ... If the environment changes, the mutation may be beneficial and it may help the organism adapt to the environment. The organisms that survive pass this favorable trait on to their offspring.

In which examples will the offspring be different form the parent(s)?
kramer

Answer:

Genes are transferred from parents to offsprings by inheritance. Each offspring receive half of their genes from mother and half from father. But answer of this question is:- Each offspring receive not exactly the same halves of the genes. This different halved of the genes are the reasons we don't.

Explanation:

The only example is with step parents, or others. Half of the parental genes are passed to the child, so a chance for one to look like the uncle or aunt of the family is high. It can also look like any before them, such as a grandmother, father, great grandmother, etc.

PKU can result from defects in phenylalanine hydroxylase (PAH), an enzyme that converts phenylalanine into amino acid tyrosine.
Inessa05 [86]

Answer:

Low phenylalanine concentration:

  • If the enzyme is inactive, PAH will look like its inactive form, with phenylalanine located in the allosteric site / inactive site so that PAH is a different shape. This will not allow as much phenylalanine to be converted into tyrosine, as we wait for Phe levels to increase.

High phenylalanine concentration:

  • If the enzyme is active, PAH will look like its regular form, with an open active site that's the size of phenylalanine so that reactions can occur. (Like a hand fitting into a glove, or a lock into a key.) Phenylalanine will be the substrate, the thing acted upon by the enzyme. This will eventually raise the amount of tyrosine that's created and lower the concentration of phenylalanine.

Think about it like this. Ever heard of homeostasis? That's how the body likes to be the same, keep everything regulated, all the time. So if there are high levels of something, the body is going to try to keep that something down, and if there are low levels, it's going to try to increase the concentration of that thing.
