The exploration of the mid-Cayman rise is intended to discover _______. a. what life may have been like before the evolution of photosynthesis b. the origins of photosynthesis c. life in shallow, coastal regions d. the chemical composition of undersea mountains Please select the best answer from the choices provided A B C D
Answer: a. what life may have been like before the evolution of photosynthesis
Explanation:
The mid-Cayman rise is an area that has little light coming in but still has life in it.
Plants are able to provide food for themselves and the rest of us by using photosynthesis to make food. Photosynthesis uses sunlight to make this food.
One would think that photosynthesis was around for as long as plants were around but this is not the case. Life on earth had existed long before photosynthesis became a valuable process to plants.
There is therefore curiosity as to how this life fed itself without using photosynthesis and this is why the life in the mid-Cayman is being explored. The way the life makes food there in the absence of light will shed light on how plants made food before photosynthesis.

Describe the role of gravity in maintaining the atmospheric layer around Earth. I will mark as brainliest
Answer:
Hi so the answer is that Gravity pulls the gas molecules towards Earth's center. The pull of gravity is stronger closer to the center at sea level. Air is denser at sea level where the gravitational pull is greater. Gases at sea level are also compressed by the weight of the atmosphere above them.

Starch is a polysaccharide used as a component of cell walls in plants.
True
False
Answer:
false
Explanation:
is type of carbohydrates
False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.
What are structural component of cell wall?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.

Answer:
Relative Humidity- Low
Air tempurature-cold
Air Pressure-low
Explanation:
High pressure, warm temperatures, and high humidity are factors that creates snow.
What are the factors that create 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.
