State four ways in which the mammalian skin responds to low temperature in the environment
When you're out in cold climate, your skin starts shivering so the blood vessels will acquire and keep you as warm as possible.
But if there's a heat wave, you'll sweat to increase the blood flow to the veins, which in turn increases perspiring. This process chills you off as the water disappears from your skin.
How does the skin respond to low temperature?If the skin temperature drops below 37°C, a variety of rejoinders are started in the skin to have the warmth within the body and to increase heat display . These include vasoconstriction, end of sweating, and erection of follicles to increase insulation.
Thus, this could be the answer.

Cellular respiration release CO2 and photosynthesis absorbs CO2. These two reactions are part of which biogeochemical cycle?
A. Carbon cycle
B. Water cycle
C. Phosphorus cycle
D. Nitrogen cycle
Answer:
A
Explanation:
A. Carbon cycle
Cellular respiration is the metabolic reaction that occurs in the cells of organisms. Cellular respiration and photosynthesis both add carbon dioxide to the biogeochemical cycle. Thus, option A is correct.
What is a biogeochemical cycle?The biogeochemical cycle is the process that transfers and moves the abiotic chemical factors through the various spheres of the earth. It includes carbon, water, nitrogen, phosphorus cycle, etc.
The process of cellular respiration releases carbon dioxide as the waste gas into the atmosphere that gets consumed by the plants to make energy that gets eaten by the organism that again releases the carbon dioxide. This cycle of carbon goes on from the producer to the consumer in the ecological chain.
Therefore, cellular respiration and photosynthesis contribute to the carbon cycle.

How and why do water and carbon dioxide function as raw materials during photosynthesis?
Review how sunlight provides the energy to carry out reactions to release oxygen and produce energy-rich carbohydrates.
Answer:
plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
(if this isnt what your asking just let me know and i do it again)
Explanation:
photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxideand water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
sunlight, water and carbon dioxide helps to produce energy storing carbohydrates.The energy from sunlight drives the reaction of carbon dioxide and water molecules to produce sugar and oxygen, as seen in the chemical equation for photosynthesis.
carbon dioxide + water➡️sugar + oxygen
