What phenomenon occurs in females as a result of x-chromosomes inactivation

Biology
1 answer:
Arada [10]3 years ago
3 0

This happens early in embryonic development in females, where one of the two X-Chromosomes is randomly (and permanently) inactivated, as you said, in cells other than egg cells.

This phenomonon is actually called X-Inactivation.

X-Inactivation make sure that females, just like males, have a single functional copy of the X Chromosome in each and every one of their cells in their body.

Glad I could help, byee now

Ann [662]

The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.

In the ecosystem, the living and non-living things interact over time leading to exchange of energy.

A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.

The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).

The energy flow is indicated with an arrow thus,

grass ---> rabbit -----> wolves.

Food chain, therefore includes linear sequence of organisms.

Food web on the other hand illustrates a complex feeding relationship within the ecosystem.

The food web is made up of a prey that can be eaten by more than one predator.

Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

Draw a flow chart of the steps that would be employed by a neutrophil to eliminate a bacterial cell. Assume that no antibodies a
lord [1]

Answer:

The neutrophil is the first line of defense, it is called as PMN OR POLYMORPHONUCLEAR NEUTROPHIL, this cell is said to be the first line of defense for the first to reach the area of ​​infection or in the area of ​​trauma, this upon reaching that area (where it is attracted by defense chemomodulators) it recognizes the bacteria or the foreign body as an antigen, since these do not present the cellular histocompatibility complex of our organism, by recognizing it as an antigen, this cell can detect that it is not something typical of our body but something new that was inoculated, is how this phagocyte to the bacteria and induces its own programmed cell death.

In an injury or infection, the purulent collection is not only debris and pathogenic microorganisms, but they are dead cell bodies of PMNs that induce their own cell death with the battery inside to be able to inhibit its advance in our body, when this phenomenon passes the PMN it is called a peach.

Explanation:

In the event that no antibodies are present, it would not change much if it is the first time that the bacteria enters our body since the formation of antibodies by the lymphocyte cell line occurs as the last stage of immunity (neutrophils appear first, then the antigen presenting cells and finally the lymphocyte lineage in charge of making immunological memory with antibodies).

The PMN are guided more than anything by the humoral factor of the immune response, but the proinflammatory factor like cytokines or leukins, but not by the antibodies, that is why he wrote this process of bacterial assimilation in the response.
