Answer:

r-selected species (e.g., American bullfrog)

Explanation:

The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).

<h2>Answer is option "A"</h2>

Explanation:

Oils and fats, which in science are called lipids, are known as amphipathic molecules. These molecules have two distinct ends to them: a water-loving (hydrophilic) side and a water-fearing (hydrophobic) side. While the hydrophilic sides of a lipid will associate with the water in a solution, the hydrophobic sides of the lipid all cluster together to 'hide' from the water. Lipids therefore cluster together and form spheres where the hydrophobic sides are in the center away from the water while the hydrophilic sides are on the outside, associating with the water.
The ability of the atoms within a group to form hydrogen bonds with the water molecules around them makes them hydrophilic. Oxygen and nitrogen atoms readily form hydrogen bonds with water molecules, so any organic molecules that have oxygen or nitrogen atoms bound to their carbon skeletons will be hydrophilic.
For example, if we take the molecule for cholesterol, we see the OH group on the left is hydrophilic and will form hydrogen bonds with water, while the ring structures, which only consist of hydrogen and carbon atoms, are hydrophobic and will not associate with the water.
There are many different kinds of lipids with different functions. Lets start by examining phospholipids, which compose the cell membranes of animals. They form lipid bilayers, with one set of hydrophilic heads facing the exterior of the cell membrane and the other set facing the interior (as you can see on the diagram on screen). The hydrophobic portions of the lipid bilayer - the lipid tails - face towards one another, which allows them to hide away from the water inside and outside of the cell.
So,the right answer is option A "amphipathic molecules".

What stage does cytokinesis generally overlap with in the typical cell cycle?

gizmo_the_mogwai [7]

Cytokinesis generally overlap with the typical cell cycle in the telophase stage. Telophase is the last stage of mitosis; where the sister chromatids reach opposite poles. Telophase and cytokinesis occur simultaneously, during cytokinesis the cell splits in two once the DNA has been replicated and pulled to opposite ends of the cell.
