Answers

Answer 1

Answer:

They are produced by the lacrimal glands above your eyes. They drain into tiny holes in the corners of your upper and lower eyelids before traveling through small channels, and down your tear ducts to your nose. Our tears taste salty because of electrolytes.

What are cytokinesis and mitosis?

Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.

Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.

Thus, option "B" is correct.

Blood Blood has four main components:Plasma is a straw-colored fluid. It is about 90 percent water and 10 percent dissolved gases, salts, nutrients, enzymes, hormones, waste products, plasma proteins, cholesterol, and other important compounds. Parts of plasma help control body temperature, transport substances, and fight infection. Plasma proteins are involved in blood clotting.Red blood cells transport oxygen. Blood gets its red color from the iron in hemoglobin, a protein that binds oxygen in the lungs and releases it in the capillaries.White blood cells guard against infection, fight parasites, and attack bacteria.Platelets are cell fragments involved in blood clotting.

Lisa sees the image below as she researches the behavior of light.

A clear glass of water with a metal spoon inserted halfway into it. There is an offset between the top half of the spoon and the bottom half of the spoon.

Which behavior is the spoon in the top image most likely being used to illustrate?

refraction
absorption
reflection
bounce

Answers

Answer:

THE ANSWER IS REFRACTION

Explanation:

The spoon half dipped inside the water is appeared to be bent. This is due to the optical  phenomenon called refraction.Refraction is the property of light by virtue of which light ray bends away or towards the normal at the point of incidence when it incidents obliquely at the refracting surface.In the given figure, light rays are coming from air which is optically rarer medium as compared to water. So, the ray, after striking the air-water interface, gets bent towards the normal in the optically denser medium i.e water.  It is so because the velocity of light in optically denser medium is less as compared to rarer medium.We view the object due to the light. As light rays are bent, so the spoon is appeared to be bent.

Answer:

(2) Photosynthesis

Explanation:

The biological process, by which oxygen and food is taken in, ATP is produced by the green plant cell, and carbon dioxide and water is released, is called photosynthesis.

The electron transport system, photosynthetic photosystem, reduction routes, and other components are all included in photosynthesis, which is the most complex physiological process in plants. Thus, option A is correct.

What combine process occur during photosynthesis?

A reaction that is endothermic is photosynthesis. This indicates that without energy, it cannot happen (from the Sun).

The palisade and spongy mesophyll cells of plants include chloroplasts, which contain chlorophyll.

Mineral nutrients that plants need in great numbers include potassium (K) and magnesium (Mg). Both components play a crucial role in photosynthesis and the consequent long-distance transfer of photoassimilates.

Therefore, biological process is represented in the diagram is photosynthesis.
