Although LTP is one of the main ways that neurons learn, scientists have identified other mechanisms. One of the most intriguing

mechanisms that have been recently discovered, is "activity-dependent myelination," which involves preferential myelination of axons that are active during learning.
Although we don't fully understand this process, this suggests that _______ in the central nervous system are likely to play some role in learning, as well.

a) Astrocytes
b) Microglia
c) Oligodendrocytes
d) Schwann Cells

Answer:

a) Astrocytes

Explanation:

The astrocytes are components of the central nervous system that provide the necessary supports that the brain needs to perform vital tasks such as learning and other daily activities. They are typical cell types in the central nervous system that aid blood flow in the brain as well as the migration of neurons.

Both adult and embryonic stem cells have the potential to be used for medical treatment. Evaluate the potential use of adult and
ICE Princess25 [194]

Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.Research carried out with the use of these cells has demonstrated their effectiveness in the treatment of various diseases, such as leukemia, heart disease and hematological diseases. Embryonic stem cells, in turn, have the ability to form any tissue in the body.

<h3>How are embryonic stem cells used?</h3>

Stem cells have the ability to differentiate and self-renew. For this reason, they can be used in the treatment of degenerative diseases. Stem cells stand out for their ability to transform into different cell types, that is, they are cells with a great capacity for differentiation.

<h3>What diseases could be treated with the use of Embryonic Stem Cells?</h3>

  • Diseases that can be treated with stem cells
  • leukemias. Leukemia is a generic term used to describe the “cancer” of leukocytes, the white blood cells.
  • Thalassemias.
  • Neuroblastoma.
  • Primary immunodeficiencies.
  • Sideroblastic anemia.
  • Metabolic diseases.
  • Sickle cell anemia.

With this information, we can conclude that Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

Many anti-evolutionists believe that since science doesn't have answers for all questions; scientific conclusions are not necess
Basile [38]

Answer:

In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions  

Explanation:

A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.

Answer the following:Meiosis / Mitosis:1. ____One division consisting of prophase, metaphase, anaphase, and telophase. 2. ____Pr
Inessa05 [86]

Answer:

The correct answer will be-

1. Mitosis

2. Meiosis

3. Mitosis

4. Meiosis

5. Meiosis

6. Meiosis

Explanation:

A cell can divide by one of the two ways of cell division which are: Mitosis and Meiosis.

During mitosis, a cell undergoes four stages of distribution of nuclear material which are prophase, metaphase, anaphase, and telophase and easily characterised.

The mitosis division produces cells with the same genetic material called clones and is involved in the division of the somatic cells. This helps in the growth and repair of the damaged tissue.

Meiosis type of cell division divides and form the four haploid cells from parental cells. The process produces haploid cells in two stages: Meiosis I and Meiosis II. The tetrad formation takes place during the prophase I of the meiosis I.
