How does the pupillary response prevent injury? What would happen without it?

Answers

Answer 1

Answer: Pupils dilate and constrict in order to allow an adequate amount of light to pass through the retina. Both great or small amount of light will damage retina and vision. For example, if eyes are exposed to eyes suddenly, and pupils do not constrict, a great amount of light will pass to the retina and the vision will be damaged. Similarly, if there is no enough light and pupil do not dilate, a small amount of light will pass to the retina and, again, the vision will be damaged.

Answer 2

Answer:

Part I

In extension to measuring the amount of light that enters the eye, the pupillary light reflex presents a helpful diagnostic tool. It provides for examining the uprightness of the sensory and motor functions of the eye. if your pupils didn't shut suddenly when abruptly disclosed to light, you'll get a tremendous shot of light (simultaneously with UV rays and other possibly dangerous rays) to your retina, which can severely mess up your vision.

Part II

Without it, we would go blind. If there is not sufficient light and the pupils do not dilate, a small number of light will pass to the retina and the image will be damaged.

Answers

In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins. Proteins are biological macromolecule and mostly composed of enzymes. Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators.

Organisms within an ecosystem are ___________________factors in that ecosystem.a. abiotic
b. biotic

Answers

Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.

What are biotic factors?

The term biotic factors has been defined as living factors present in the ecosystem. Biome is a separate biogeographical region that contains its own living and non-living factors along with a characteristic climate. The examples of biomes are: Tundra, Temperate, Desert, etc.

Changing a biotic or abiotic factor can affect each other or even the entire biome because these factor live in a state of dynamic equilibrium by being interdependent on each other. Therefore, if this equilibrium is disturbed then the survival of some living organism may be disturbed that can eventually lead to ecological succession.

The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community.

Therefore, Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
