It’s definitely c ahhhhhh stupid characters i have to do 20
Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
Hello, I figured that the question was missing its options so I went online to find them. Here they are:
All of the following are true of the thymus gland, except that:
A) activates B cells.
B) reaches its greatest relative size during the second year of life.
C) involutes after puberty.
D) produces T cells.
E) lies in the anterior mediastinum
Answer:
The correct answer is: A) activates B cells.
Explanation:
The thymus is a lymphatic organ that is located in the anterior superior mediastinum (a compartment in the thoracic cavity), in front of the heart, with the function to mature T cells (one of the types of lymphocytes, white blood cells very important for the functioning of the immune system).
The thymus is more active and bigger during childhood, when puberty hits it involutes and its functional tissue is replaced with adipose tissue (fat).
<u>B cells are not activated in the thymus, they mature in the bone marrow</u>.
Answer:
Allosteric activators bind to locations on an enzyme away from the active site, inducing a conformational change that increases the affinity of the enzyme's active site(s) for its substrate(s). Allosteric inhibitors modify the enzyme's active site so that substrate binding is reduced or prevented.
