The ability to internalize material from outside the cell is important for several cellular processes including the ingestion of essential nutrients, removal of dead or damaged cells from the body, and defense against microorganisms. <span>Eukaryotic cells </span>internalize fluid, large and small molecules, and even other cells from their surroundings by a process called endocytos<span>There are two main types of endocytosis that are distinguished by the size of the vesicle formed and the cellular machinery involved. Pinocytosis (cell drinking) describes the </span>internalization<span> of extracellular fluid and small </span><span>macromolecules </span><span>by means of small vesicles. </span><span>Phagocytosis </span>(cell eating) describes the ingestion of large particles such as cell debris and whole microorganisms by means of large vesicles. While all eukaryotic cells are continually ingesting fluid and molecules by pinocytosis, only specialized phagocytic cells ingest large particles.<span>
</span>is. During endocytosis, the plasma membrane of the cell forms a pocket around the material to be internalized. The pocket closes and then separates from the inside surface of the plasma membrane to form a membrane-enclosed bubble, or vesicle, containing the ingested material.

How does pollution threaten coral reefs? Answer using at least 3 complete sentences.
Lostsunrise [7]

When pollution occurs on land it travels to the waters which causes the pollutants to enter the water. When pollution enters the water, it damages the algae on the coral. It also lowers water quality, smother the coral reefs, and it speeds the growth of the damaging algae. All these make the coral reefs more susceptible to disease which stops the reefs growth and reproduction.

Which is an example of codominance? (1 point)
Dafna11 [192]

Answer:

roan coat color in horses

Explanation:

Codominance is one of the Non-mendelian inheritance patterns in genetics i.e. does not follow Mendel's principles of inheritance. Codominance is a phenomenon whereby an allele is neither dominant nor recessive to another in a gene i.e. one allele is not phenotypically expressed over the other. Hence, both alleles are simultaneously expressed in their heterozygous state.

An example of codominance is the roan coat color in horses where the colored (B) and white (W) alleles are both dominant in the coat color gene, hence, the horse expresses both black and white coat phenotypes known as ROAN (BW). The black and white alleles are said to be CODOMINANT.
