Explain the all-or-none law of action potentials and describe the effect of increased stimulus strength on action potential prod

uction. How do the refractory periods affect the frequency of action potential production
Biology

Schach [20]2 years ago
6 0

If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.

Blood type A- would give which of the following results?
natka813 [3]

Answer:

(B) agglutination with anti-A antibodies.

Explanation:

ABO blood type is based on two types of antigens: A and B antigens. The anti-A antibodies react with antigen A while anti-B antibodies react with antigen B.  

Blood type A has antigen A on the surface of its red blood cells and anti B antibodies in its plasma. Due to the presence of antigen A on its red blood cells, the blood type A shows agglutination with anti A antibodies.

AlexFokin [52]

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.
