Members of different species do not produce offspring due to:

Biology
2 answers:
exis [7]2 years ago
6 0

Answer:

Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation. These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

Explanation:

So the answer would most likely be C.

What processes allows cells to concentrate material that is present only in very small amounts in the extracellular fluid?
AleksandrR [38]

Answer:

receptor-mediated endocytosis

Explanation:

  • A selective mechanism that is responsible for endocytosis and transcytosis of the small amounts of materials that are present in the extracellular fluid is known as receptor-mediated endocytosis.
  • The various molecules that can be taken up by this process include hormones, metabolites, proteins as well as certain viruses.
  • This process is also known as clathrin-mediated endocytosis.
  • In this process, the receptors that are present on the surface of the proteins are captured by a molecule which is the target site for the protein and internalized by membrane internalization (endocytosis).
  • The vesicle formed by endocytosis is a clathrin coated vesicle.

All living organisms break down sugar to obtain energy using cellular respiration, Which of the following chemical reactions rep
Ghella [55]

Answer:

The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy

Explanation:

Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.

<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:

              <em>              C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂ + ATP ↑</em>

<em>                Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>

This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.

The other reactions:

  • <em>oxygen + water </em><em>→</em><em> glucose + lactose </em>
  • <em>glucose + lactose </em><em>→</em><em> oxygen + water </em>
  • <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>

<em>do not represent the components or the order of the reactions that occur in aerobic cell respiration</em>

Can someone help me with a summary of asexual and sexual reproduction summary?
fenix001 [56]

Answer:

Asexual reproduction is when the parent reproduces without having any sexual contact with a partner and they don't need any kind of fertilization from another partner, sexual reproduction requires both a male and female partner, and fertilization of eggs must occur.

A postitivly charged atom has? A.Lost electrons B. Lost protons C.Gained electrons D.Gained protons
Kipish [7]

Not to be too picky, but the question ought to say a positively charge ion rather than atom.

I will assume that is what you mean. An ion, using ordinary means, will be positive if it loses electrons (which are negative).

An ion can never gain protons. Left alone, the nucleus will remain unchanged for the rest of eternity. D is wrong.

C is wrong. If electrons are gained, the ion will go negative.

B is wrong for the same reason D is. An ion can't gain protons and it can't lose them.

A is the answer.
