1. Define Chemosynthesis?

the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.

2. List some organisms that undergo Chemosynthesis?

Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic.

3. Which organisms conduct photosynthesis?

Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

4. Define photosynthesis

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

5. Type out the chemical equation of photosynthesis?

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Put the following structures in order of superficial to deep based on their descriptions:
AleksandrR [38]

Answer:

The right order is 3, 1, 2.

Explanation:

The most superficial layer is 3, which describes the Cornea. This layer, which is first hit by light, is made of transparent and resistant fabric. It protects the eyeball from trauma and contamination and helps shape the globe and refract light.

Then, the layer described as 1 is the pigmented part that has melanocytes, which may be the uvea that consists of the whole of the iris, choroid membrane and ciliary processes.

Finally, the deepest layer in this question describes the lens, which is a gelatinous biconvex lens. This important structure enables the eye to focus on objects.
