Answer:

<u>Codominance.</u> This is shown by the calico cats, who have both black and orange phenotypic expression; the black and orange are not mixed like incomplete dominance, and one is not entirely dominant over the other. (A common example is the roan cow, whose fur is a bit red, a bit white.)

<u>Sex-linked inheritance.</u> Since calico cats are said to always be female (which actually isn't entirely accurate, by the way) this means that the coat color is sex-linked. It's found on the X chromosome, so a female cat can have one X black and one X orange chromosome. This is only possible in males when they are nondisjunct and inherit two Xs along with their Y... but that's a completely different story. :)

The answer is right below.

The bulk of this species’ diet consists of fish in the teleost infraclass, including dragonfish, rattails, anglerfish, and more. They are also known to feed on crustaceans and cephalopods like squid.

These sharks will prey on fish found both on the sea floor and in the water column. Because they are so slow moving, scientists believe these sharks are ambush predators. Their pinkish-red skin actually blends in when in the deep sea.

The viral pathogen that causes cold sores can remain inactive in the body for a long time between disease outbreaks. How is this
Serhud [2]

This disease is classified as a latent disease.

<h3>Classification of diseases</h3>

Latent disease is a classification of disease whereby the infectious agent remains inert in the body of its host between episodes of recurrent diseases.

Examples of viral pathogens that causes latent diseases include:

  • <em>Herpes simplex, </em>

  • <em>Varicella zoster, </em>

  • <em>Epstein-Barr</em>,

  • <em>Human cytomegalovirus, </em>

  • Adenovirus, and Kaposi's sarcoma.

The infection caused by the listed viral pathogens exhibit a latent disease phase whereby there is no noticeable symptoms of infection.

A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human
Delicious77 [7]

Most proteins in living organisms are composed of 40 amino acid residues in total, and nine of those are crucial for human health.

Which majority of amino acids make up proteins in living things?

  • Only twenty different amino acids, each with a distinct side chain, make up proteins. Different chemistries can be found in the side chains of amino acids. The majority of amino acids contain side chains that are nonpolar.
  • There are nine essential amino acids:
  1. tryptophan
  2. valine
  3. isoleucine
  4. leucine
  5. lysine
  6. methionine
  7. phenylalanine
  8. threonine
  9. methionine

What Constitutes Proteins?

  • Amino acids are the basic units of proteins. They are tiny chemical compounds with an alpha (central) carbon coupled to an amino group, a carboxylic acid group, hydrogens, and a changeable element known as a side chain.
  • A protein is made up of a lengthy chain of amino acids that are connected by peptide bonds. The biological process that links the carboxyl unit of one amino acid towards the amino group of a nearby amino acid results in the extraction of a water molecule, forming peptide bonds. The main structure of a protein is thought to be its linear amino acid sequence.

grin007 [14]

Explanation:

In biology, the term spore designates a single-celled or multicellular microscopic body that is formed for dispersion and survival purposes for a long time (dormancy) under adverse conditions, and which is generally a haploid cell. In many eukaryotic beings, it is a fundamental part of their reproduction, originating a new organism by dividing by mitosis (especially in fungi) or meiosis (plants), without having to merge with another cell, while in some bacteria it is instead a inactive stage, resistant to desiccation and for non-reproductive survival purposes. The term derives om the Greek σπορά (sporá), "seed".

The spore is an important element in the biological life cycles of plants, fungi, algae and some protozoa, which usually produce spores in structures called sporangia. In plants, spores are gametophytes within their life cycle and allow the dispersion of the propagules at the same time. Most fungi produce spores; those that do not are called asporogenic fungi.

Setler [38]

Answer:

B. urbanization

Explanation:

In urbanizing stage, death rate quickly declined because of the improvements in agricultural aspect which goes down to food supplies, health care delivery, medicine improvements, and even  the investments in sanitation and infrastructure which contributes to the increasing life expectancy of the people and lesser diseases which cause deaths.  Though birth rates remain almost the same, but young population continues to grow because of the low death rate.
