Liono4ka [1.6K]

Answer:

Mark pathogenic cells for destruction. (Ans. B)

Explanation:

Antibodies are generated by the plasma cells, and once these secreted, they attach quickly to the surface of the toxin and stop the toxin from infecting the normal body cell by blocking key extracellular sites.

Antibodies also help to mark pathogens for destruction by the help of macrophages or neutrophils and they are known as phagocytic cells because they are highly excited to macro-molecules complexed with antibodies.

The scientific name of the sugar maple is Acer saccharum. What does each part of the name designate?
irinina [24]

Answer:Acer represents the genus name while

saccharum represents the species.

Explanation:

In a way to classify organisms, biologists used certain important common features to structure them into groups. The arrangement of living organisms in this hierarchy from the highest level to the lowest is as follows:

Kingdom--> phylum-->class-->order--> Family-->genus--> species.

The largest group of organisms is kingdom while species is the smallest unit of classification.

The common name of the plant used in the question above is sugar maple. Biologist, however, use a standard system to name living organisms. Each kind of organism is given two names, hence the term BINOMIAL NOMENCLATURE.

--> The first name is the name of the genus to which the organism belongs.

--> The second name is the name of the species to which it belongs.

Both names are printed in italics with only the genus name having an initial capital letter. Hence, the scientific name of sugar maple is Acer saccharum( in italics).
