What are the reactants of photosynthesis??

Answers

The reactants of photosynthesis are water, light and carbon dioxide, while the products are oxygen and sugars. Cellular respiration occurs in direct synchronicity with this process, using the products of photosynthesis as its reactants and producing its reactants. 

Hope this helps :D 
(If wrong please notify me asap)

Final answer:

The primary reactants of photosynthesis are water, carbon dioxide, and light energy, usually from the sun. Through a complex series of reactions, photosynthesis transforms these inputs into glucose and oxygen.

Explanation:

The process of photosynthesis, a key biological process, requires certain reactants or inputs to proceed. The primary reactants of photosynthesis are water (H₂O), carbon dioxide (CO₂), and light energy, typically from the sun. In the photosynthesis process, these inputs are transformed through a complex series of reactions into the products glucose (C6H12O6), a simple carbohydrate molecule that stores energy and the structural backbone for much of life on Earth, and oxygen (O2).

The simplified chemical equation representing photosynthesis is: 6CO₂ + 6H₂O + light energy --> C6H12O6 + 6O2

So, in a nutshell, photosynthesis uses carbon dioxide and water, along with energy derived from sunlight, to produce energy-storing glucose and oxygen.

What is the main responsibility of the endocrine system?

Answers

Answer:

Endocrine system may be defined as the system that controls the homeostsis of the organism by the production of hormones in the form of chemical messenger. Endocrine glands secrete their product directly into the blood stream.

The endocrine system regultes the proper growth and body metabolism. These system regulates the sugar level, calcium level and level of other ions in the body. The endocrine system is also responsible for the functioning of gonads.

the endocrine system produces important human hormones which regulate imprtant processes in the human body such as metabolism of sugars and production of growth and reproductive hormones.

Describe how the structures of the epidermis allow it to provide immediate and indirect protection to underlying tissues.

Answers

The stratum corneum is the outermost layer of the skin. It is a thick row of dead cells that contain keratin. Keratin is responsible for keeping the skin elastic and in preventing the underlying cells from drying out. The skin is called the Integumentary system of the body, it is responsible for protecting muscles, bones, and vital organs inside the body. It serves as a covering that is composed of two layers the Epidermis (outermost layer) and the Dermis (inner layer). They provide the necessary impulses for temperature control in the body through the different nerves and receptors.
