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.

Answer:

I don't really understand what the question is, but I'm pretty sure you're asking for which molecules that will be needed; Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus

Explanation:

-Carbohydrate consists mainly of Carbon, Hydrogen, Oxygen, simple sugars have the basic formula of (CH2O)n. Some modification can be made to the sugar, but the main formula consists only with Carbon, Hydrogen, Oxygen.

-Proteins consists mainly of Carbon, Hydrogen, Oxygen, and Nitrogen for the amide groups. Some amino acid will need Sulfur for it's R Group.

-Fats consists mainly of Carbon, Hydrogen, and Oxygen just like Glucose.

-Nucleic Acids consists mainly of Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus for the backbone of the Nucleic Acid. Nitrogen will be needed for the Nitrogenous Base.

I hope this is the answer you're looking for!

The discarded theory of blending inheritance most closely resembles what inheritance

pochemuha

The discarded theory of blending inheritance most closely resembles incomplete dominance.

<h3>What is blending inheritance?</h3>

An antiquated biological notion from the 19th century is the concept of blending inheritance.
According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
Offspring thus combines the traits of both parents.
Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

Why is DNA replication more important in eukaryotes than in bacteria

dybincka [34]

The extra step of dissolving the nucleus is needed during DNA replication in a eukaryotic cell, whereas bacteria are prokaryotic and therefore don't have a nucleus so they don't need this extra step.
