Answer:

A tan might indicate sun damage to the skin.

Explanation:

Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.

A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.

Answer:

A or "The blood would not be able to carry oxygen."

Explanation:

"Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin."

Answer:

Relative Humidity- Low

Air tempurature-cold

Air Pressure-low

Explanation:

High pressure, warm temperatures, and high humidity are  factors that creates snow.

Snow and/or ice formation requires temperatures below freezing, both in the atmosphere and close to the ground.

Something that will induce the moist air to rise, forming clouds and precipitation, moisture, produces precipitation and clouds.

Water that has frozen solidly is snow, and the atmosphere (layer of gases around Earth) contains water in the form of vapor (gas). When there is a lot of vapor present, clouds develop, fill up with water droplets, and eventually begin to rain.

Therefore, when a very cold water droplet freezes onto a pollen or dust particle in the atmosphere, a snowflake starts to form.

False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.

Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.

Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.
