vazorg [7]

Endocrine system regulation slowly happens but produces long-lasting effects, whereas nervous system regulation quickly takes place with short-term effects.

Endocrine system can regulate many things in the body that control the metabolism. The effect shouldn't be instant, but it should be good for long term effect. Nervous system need a much faster reaction because it responsible for "fight or flight" reaction. A slow nervous system will cause the organism caught by predator easier.

12345 [234]

Answer:

The correct option is C: antigen-binding sites

Explanation:

The antibody is shaped much like the letter Y in the English alphabet. It has two antigen binding sites that are identical in nature. The specificity of these sites is determined by the amino acid sequence that makes it up. Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.

Vadim26 [7]

Answer:

Diffusion rate is 1.96 × 10^{-3} cm^{2}/s

Explanation:

Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.

diffusion rate = \frac{area}{time}

Given that; diameter = 15 mm, time = 15 minutes.

The dye spread in a circular form, so that;

area = \pir^{2}

r = \frac{diameter}{2} = \frac{15}{2} = 7.5 mm = 0.75 cm

area = \frac{22}{7} × (0.75)^{2} = 1.7679 cm^{2}

time = 15 minutes = 15 × 60 = 900 seconds

So that;

diffusion rate = \frac{1.7679}{900}

                      = 0.0019643 cm^{2}/s

Diffusion rate is 1.96 × 10^{-3} cm^{2}/s
