Why do you think species remain in a stage of stasis?

Biology
2 answers:
statuscvo [17]3 years ago
5 0

I believe that species remain in a stage of stasis because they have completely adapted to the environment they are in and are able to live successfully without any evolutionary changes. The species has all the necessary traits in order to survive.


Answer: A) A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.

The HR diagram represents stages in the life cycle of a star.
Veseljchak [2.6K]

white dwarf

Explanation:

A appears on the chart at the point of low luminosity but high surface temperatures. This indicated  a White Dwarf

A red giant is highly luminous stars mainly because of its large size. However, its surface temperature is hot a high when compared to white dwarfs. White dwarf surface temperatures can reach billions of degrees kelvin while red giants reach up to 5000 K on their surface.

A white dwarf is the last sequence of a low-mass star cycle and follows the red giant phase.

Differentiate Humoral immunity vs cell mediated immunity
trapecia [35]

Answer:

Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.

The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.

Are the offspring of parents who are both homozygous dominant for normal red blood cells in danger of getting sickle-cell anemia
Ksju [112]

Answer:

If both parents do not have sickle-cell anemia, than the possibility is low.

Explanation:

If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.

If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.

When both parents have sickle cell anemia, their child will definitely have it.
