Answer:

The options

A. inear perspective

B. texture gradient

C. motion parallax

D.perceptual constancy

The CORRECT ANSWER IS D.

D.perceptual constancy

Explanation:

Perceptual constancy, is also know as Object Constancy, or Constancy Phenomenon. It is the ability of the brain to view perception of objects not minding the variations in retinal image when an object adjusts position or distance from the viewer. It helps animals and humans to view familiar objects as possessing standard shape, size, colour, or location irrespective of variations in the angle of perspective, distance, or lighting despite the fact that the illumination and retinal images may vary.

Another example is the distance between a door and an individual such that no matter the distance between a door and a person, the person still perceive it as possessing a constant size.

I want an essay on the benefits of plants. Serious answers only.

grandymaker [24]

Answer: I highly suggest that you reword this but here it is...

Plants are beneficial to the lives of many species on Earth. They provide us with oxygen, while also reducing the amount of carbon dioxide in the atmosphere.

Plant go through a process called "photosynthesis." This process allows them to take in carbon dioxide, water, and sunlight, and omit oxygen and glucose. Without plants, this process would only occur in microorganisms. By themselves, microorganisms do not have enough numbers and power to be able to provide enough oxygen for the rest of the species on the planet. All species that rely on oxygen would eventually perish.

Plants also prevent erosion. With their roots, plants hold down soil and stop the soil from moving. They provide structure and strength to the loose soil. If plants were not there to hold down soil, it would be entirely up to humans to provide structure in the soil.

Finally, plants are important to us because they provide us with a food source. Humans use plants as a major source of energy. We eat plants, and mass produce them to feed ourselves. Plants are also a major food source for other animals that we rely for food. Animals that we eat get there energy from plants. If we wiped out the complete bottom part of the food chain, none of the other animals would survive.

Overall, plants are beneficial to us in many ways. They provide us with energy, stop erosion, and give us oxygen. Without plants, it would be impossible for humans to survive, and we would eventually perish.

Zielflug [23.3K]

<u>Epithelial tissue</u> are affected by muscular dystrophy.

The correct option is C.

<h3>What is muscular dystrophy?</h3>

A set of disorders affecting the muscles called muscular dystrophies are brought on by genetic abnormalities. Muscle sluggishness impairs mobility over time, making daily chores challenging.

<h3>What is epithelial tissue and its function?</h3>

The epithelium is a type of bodily tissue that forms the coating on all of your body's internal and external surfaces, lines your hollow organs and cavities, and makes up the majority of your glands.

The body contains a variety of epithelial tissues. They are the main tissue in glands, line body cavities and hollow organs, and form the coating of all body surfaces. They carry out numerous tasks, including those related to defense, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
