stellarik [79]

Answer:

The correct answer is - speciation is sympatric.

Explanation:

Sympatric speciation is a process of speciation that takes place when there is reproductive isolation between two populations of a species without any geographical separation.

This speciation takes place in the population with come ancestors as given in the question both pods of dolphins lose their ability to interbreed due to the sympatric speciation without any geographical separation.

Thus, the correct answer is - speciation is sympatric.

How do the circulatory and respiratory system interact to provide muscle cells with oxygen during a long distance race?
Orlov [11]

Answer:

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

Answer:

The two main reasons are nonpolar core of the bilayer and the active transport.

Explanation:

The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.

If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.

One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>
