Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
Answer:
Lets consider the dominant allele to be represented by T and the recessive allele to be represented by t.
The punnet square can hence be completes as:
T t
T TT Tt
t Tt tt
The blanks can be filled as:
1: t
2: T
3: Tt
4: T
5: Tt
6: t
7: TT
8: Tt
9: tt
10:Tt

I believe this is the answer
Explanation:
Whenever two objects<span> are touching, they usually </span>exert forces on each other<span>. The </span>force<span> of gravity, on the </span>other<span> hand, is an </span>example<span> of a </span>force<span> that exists between </span>objects<span> without them having to be in contact. </span>Objects<span> with </span>mass exert forces on each other<span> via the </span>force<span> of gravity.
