Nuclear division in eukaryotic cells
evablogger [386]3 years ago

Explanation:

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

Cross a pure A type blood with a pure B type blood;write the phenotype, genotype, and ratios
Irina18 [472]
If one parent has the pure A blood type (both alleles are A) is with genotype AA The other parent has the pure B blood type (both alleles are B) is with genotype BB
 Crossing these two: AB AB AB AB
<span>which means that all of the children will have AB blood type (phenotype). This happens because of the codominance. The A and B alleles are codominant and therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB.</span>

Imagine you are a plant breeder. Friends sent you two different varieties of a snapdragon flower; each have golden leaves rather
Neporo4naja [7]

Answer:

Complementation.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.

Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.

In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.

Hence, the above breeding is an example of complementation.

krek1111 [17]

Answer: All cells come from preexisting cells.

Explanation:

The given paragraph is about cells develop from the preexisting cells. The doubling of the genetic material in the S-phase is the triggering mechanism for cell division. In the process of mitosis the genetic material get reduced. The daughter cells vary by the amount of genetic material they receive. This proves that the new cells form from the pre-existing cells.

Ng in of the muscles between the ribs or of the sternum during inspiration is called?
ddd [48]

External intercostal muscles between the ribs or of the sternum during inspiration.

<h3>what are the function of External intercostal muscles ?</h3>

Intercostal muscles are the group of muscles present between the ribs that create and move the chest wall.

The muscles have three layers such as external intercostal muscles, internal intercostal muscles, and the innermost intercostal muscles.

These muscles are supplied by  intercostal nerves, intercostal veins, and intercostal arteries.

The external intercostal muscles are involved in  forced and quiet inhalation.

They are involved in expansion of ribs and the chest cavity and originate from ribs.

The internal intercostal muscles are involved in forced exhalation but they depress the ribs and decrease space in the chest cavity.
