Which part of the eye helps focus light rays on the retina?A.lensB.pupilC.scleraD.iris

Answers

Answer 1
Answer:

Lens focuses light rays on the retina.

Further Explanation:

The eye is the sensory organ of the organism that allows it to see the object.

The eye consist of various part:

1. Sclera-Outer covering of the eyeball is tough and has white layer called as sclera

2. Cornea-The light enters the eye through it. It is the curved layer in front of iris and pupil.

3. Pupil-It controls the amount of light entering into the eye

4. Iris-it surrounds the pupil and regulates the amount of light passing into the eyes.

5. Lens-It sits behind the iris. It focusses light onto the retina.

6. Retina-It comprises of photoreceptors and blood vessel that nourishes the former. The two main types of photoreceptor:  

a. Rods: It is responsible for night vision and are more sensitive to light.

b. Cones: It is responsible for color vision.

The eyeball is basically divided into two regions which are filled by the fluid. The two type of fluid found are

1. Aqueous humor: Is present across the space separating cornea and the lens.

2. Vitreous humor: Is present across the space separating the lens and the retina.

Answer 2
Answer:

Final answer:

In the eye, it is the lens that focuses light rays onto the retina. The pupil, sclera, and iris have other functions relating to vision but do not focus light.

Explanation:

The part of the eye that helps focus light rays on the retina is the lens. The lens is situated behind the pupil and is responsible for directing and concentrating light onto the retina. This is how we are able to see the world clearly. Without the lens, images would not be focused properly on the retina, resulting in blurry vision. Thepupil,sclera, and iris play important roles in eye function, but they are not directly involved in the focusing of light rays onto the retina.

Which of the following statements about omnivores is false?A Omnivores also exist in aquatic environments. The humpback whale, for example, feeds off plankton, making it a primary consumer.

B An omnivore is an animal that eats a diet of both plants and animals.

C Some examples of omnivores include grizzly bears, humans, skinks, raccoons, and many birds, among others.

D Since omnivores eat both plants and animals, their teeth are specialized for the food that they

Answers

Statement D is false. Unlike herbivores and carnivores, omnivores typically do not have teeth that are specialized for the food that they eat. Instead, their teeth are usually a combination of sharp teeth for tearing flesh and flatter teeth for grinding plant material.

Since certain omnivores have different teeth, option D is the false one

why does the plasma cell have a well developed endoplasmic reticulum with lots of ribosomes 

Answers

Since plasma cells make your antibodies, they need to produce a lot of protein. Also because the nucleus makes a lot of products to make proteins you need a large Golgi Body. How ER's relate to this: to do protein synthesis you need ribosomes and to have ribosomes you need the rough ER!

Answer:Within the cell, the endoplasmic reticulum synthesizes lipids and proteins. ... Proteins that are made in the cell for use by the cell-for instance, as channels in the plasma membrane-are made by the free ribosomes that dot the cytoplasm. Two types of endoplasmic reticulum are found in the eukaryotic cell.

Textures provides the clues about the formation of igneous rocks are formed . Igneous rock texture depends on the rate of cooling . Small crystals are obtained by fast cooling and last crystals are obtained by slow cooling. Basically textures state the comosition of the rocks. Textures of rock may be of different types like phaneritic and crystalline texture.

16. Plants gather the sun's energy with light-absorbing molecules calleda. pigments.
b. thylakoids.
c. chloroplasts.
d. glucose

Answers

Answer:

C

Explanation:

chloroplasts captures energy from the sun which is needed for the growth of a plant and it is also needed in the process of photosynthesis

Final answer:

Plants use pigments, primarily found in chloroplasts, to absorb the sun's energy. These pigments are housed within components of chloroplasts called thylakoids. The absorbed energy is used to produce glucose through the process of photosynthesis.

Explanation:

Plants gather the sun's energy with light-absorbing molecules called pigments.

Mainly, these pigments are found in organelles known as chloroplasts. Inside the chloroplasts, pigments like chlorophyll absorb light energy, and this is then used to produce a type of sugar called glucose in a process called photosynthesis.

So, the answer is option 'a' as pigments absorb the light from the sun.

Thylakoids are a component of the chloroplasts where the pigments are housed, and glucose is the end product of this process, not the light-absorbing molecule.
