Answer: Ducks will emigrate from the population.

Explanation: Emigrate means to move out of. If there is nowhere to live then the ducks will have to move out of population.

D. A duck flies to another pond.
The above sentence is an example of emigration. Emigration refers to moving from one area to another for a long or permanent period. In this instance, a duck is leaving the pond it originally resided in (along a population other ducks) in order to reside in another pond. Therefore, it can be said that the duck "emigrated".

saveliy_v [14]

Answer:

proteins are only able to function properly in their specific shape, they will typically stay in that configuration unless something forces them to change. When proteins change their shape, this is called denaturation. Some external forces that affect protein shape are pH and temperature

which structure in the female reproductive system is comparable to the external reproductive organs in males
Oksi-84 [34.3K]
They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.

Two protein kinases, K1 and K2, function sequentially in an intracellular signaling pathway. If either kinase contains a mutatio
Korolek [52]

Answer:

The order must be K2→K1, since the permanently active K1 allele (K1a) is able to propagate the signal onward even when its upstream activator K2 is inactive (K2i). The reverse order would have resulted in a failure to signal (K1a→K2i), since the permanently active K1a kinase would be attempting to activate a dead K2i kinase.

Explanation:

  • You characterize a double mutant cell that contains K2 with type I mutation and K1 with type II mutation.
  • You observe that the response is seen even when no extracellular signal is provided.
  • In the normal pathway, i f K1 activat es K2, we expect t his combinat ion of two m utants to show no  response with or without ext racell ular signal. This is because no matt er how active K1 i s, it would be unable to  act ivate a mutant K2 that i s an activit y defi cient. If we reverse the order, K2 activating K1, the above  observati on is valid. Therefore, in the normal signaling pathway, K2 activates K1.

Answer:

hopes it helps

Explanation:

In glycolysis, glucose molecule is converted into pyruvate molecules .

It can't be cellular respiration because it starts always with glucose i.e glycolysis. But here it is the process after glycolysis (starting from pyruvate) and changing into lactic acid. It's an aerobic respiration called as lactic acid fermentation.
