Answer is B lymphocyte.
B lymphocyte becomes a plasma cell and also produces antibodies when activated by a T cell. Different B cell lymphocytes produce one unique antibody against one unique epitope, (An epitope is the specific binding site/target on which an individual antibody binds).
(2x+5)(−mx+9)=0
In the equation above, m is a constant. If the equation has the solutions x=−5/2 and
x=3/2, what is the value of m?
-m (3/2) + 9 = 0
-3/2m +9-9 = 0-9
-3/2m = -9
(-3/2m)(-2/3) = -9 (-2/3)
m = 6
Answer:
The fossil record
Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Explanation:
Red Flag can be explained or described as signs and symptoms that can be found in either medical history of a patient or/and patient clinical examination, which may show or explain that a disorder is tie to a pathology. This means that, the signs may be a warning of a potential serious disease.
