Answer:
d. All of the above exemplify the difference between a population and an individual.
Explanation:
A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.
These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.
The t<u>unica media</u> is composed of an endothelial layer that is continuous with the endocardium of the heart.
<h3>What is tunica media?</h3>
Collagen, elastin, and smooth muscle cells make up tunica media. It is located halfway between the tunica externa and the tunica intima. The transverse arrangement of its strands and color make the middle coat (tunica medium) distinct from the inner (tunica intima). It not only supports the vessel but also alters the vessel's width to control blood pressure and flow.
Elastic fibers make up the majority of the tunica media in bigger vessels. The number of elastic fibers reduces as arteries get smaller, whereas the number of smooth muscle fibers grows. The strongest of the three layers is the tunica adventitia, which is the top layer. Elastic and collagenous fibers make up its structure.
