Which of the following is a binocular cue for depth perception?.

Answers

Where is the picture ?

A binocular cue used to assess depth between two nearby objects is called retinal disparity.

What is the binocular cue for depth perception?

The pictures that both eyes focus on to create stereopsis, or the feeling of depth, is known as binocular depth cues. Using binoculars, one may see the world in three dimensions.

Binocular depth signals can be classified as either retinal disparity or convergence. Convergence centers on a single object while using both eyes.

A binocular cue used to assess depth between two nearby objects is called retinal disparity. It accomplishes this by contrasting the various pictures from the two retinas. Because the distance between each eye is typically around two and a half inches, each eye sees different pictures.

Therefore, the retinal disparity is a binocular cue for depth perception.

The nucleotides which are found in the DNA molecule are made up of nucleoside moieties and phosphate molecule. These are of five types which include adenosine, guanosine, uracil, thymine, and cytosine.

What is a nucleotide?

Nucleotides are the organic molecules which consist of a nucleoside and a phosphate moiety. The nucleotide molecules serve as the monomeric units of the nucleic acid polymers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all life forms on the Earth.

A nucleotide is one of the main structural components, or the building blocks, of DNA and RNA molecules. A nucleotide consists of a base which has one of four nitrogenous base which could be purine and pyrimidine such as adenine, thymine, guanine, and cytosine plus a molecule of sugar and one molecule of phosphoric acid.

7. The “growing light” that appears during the first half of the lunar cycle is referred to as waxing.

8. The third quarter / 7th phase occurs at 21 days into the cycle and shows the left half of the moon illuminated.

9. In a crescent stage less than half of the Moon appears illuminated and during a gibbous stage more than half appears illuminated.

Explanation:

The "growing light" that appears during the first half of the lunar cycle is referred to as the "waxing phase" ,the first quarter phase occurs 21 days into the cycle and in the crescent stage, less than half of the moon appears illuminated.

What is the significance of the lunar cycle?

It has much significance and is related to the moon, which is a natural navigation aid for mariners, providing light at night and it has an impact on the life cycles of animals and plants, including breeding and migration, and the gravitational pull of the moon and the sun causes the tides to rise and fall.

Hence, the "growing light" that appears during the first half of the lunar cycle is referred to as the "waxing phase" ,the first quarter phase occurs 21 days into the cycle and in the crescent stage, less than half of the moon appears illuminated.

Answers

hi the answer is lens

Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.

What is eye lens?

The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.

The lens is normally clear and is located behind the iris. The pupil directs light to the lens.

Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.

Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.

The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).

Thus, eye lens helps to focus the object.

Does “survival of the fittest apply to domesticated animals? Why or why not? *

Answers

Answer:

Yes.

Explanation:

This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.

Answer:

Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.

Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.

However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on dividing cells

Answers

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.
