Why do some combinations of chromosomal centric fusions cause problems in meiosis?

Biology
1 answer:
MakcuM [25]3 years ago
6 0

Answer:

Because centric fusions modify the chromosome number

Explanation:

The centric fusion is a translocation that involves acrocentric chromosomes. During cell division, pairs of homologous chromosomes are aligned on the equatorial plane and subsequently they move to opposite poles in the cell.

Water molecules diffuse through the cell membrane through aquaporins. How are these proteins helpful in osmosis?
romanna [79]

Answer:

Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis

Explanation:

Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.

Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.

The fossils of a new species of reptile are found in deposits dating to the Permian period. Later, scients discover that fossils
allochka39001 [22]

Answer:

The correct answer is option c. "adaptive radiation".

Explanation:

The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.

If a mother is type A and has a child who is type B what are the possible blood types of the father​
jenyasd209 [6]

The possible father's  blood groups are B, AB.

<u>Explanation:</u>

If the mother blood type of A, and the father blood type is AB, B then the child is B. Each biological parent donates one of their two ABO alleles to the child. The blood types in our body are classified as the four paternal blood types and the four maternal blood types.

The blood type has the 16 combinations of the blood samples. The genetic information from the body is independently inherited to the ABO blood types alleles. In the Rh factor, the genetic information is inherited from the one parent to another.
