Answer:
A virus is a tiny infectious biological agent that can only replicate or duplicate inside the host cell. These infectious agents can infect all different types of living organisms ranging from animals and plants to microorganisms and archaea and bacteria.
Virions are ineffective particle or form of the virus outside of the host cell, with RNA or DNA and a protein capsid.
The main role of these infectious agent virions is to transfer the DNA or RNA genome from itself to the cell of host and expressed the gene which means produce proteins from the genome transferred to the host cell.
They come from the atmosphere, since plants use carbon dioxide to produce carbohydrates :)
Answer:
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
Explanation:
Trypsin and chymotrypsin are known as proteolytic enzymes which are actively involved in the digestive system. They are both secreted by the pancreas and are majorly involved in the breakdown of protein in the small intestine.
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.

<u>Three.</u>
Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. This occurs in distinct steps: 1) light fixation, 2) electron transport and NADPH production 3) ATP generation, then 4) carbon fixation and carbohydrate production.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Further Explanation:
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.
Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.
Additionally,
- Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
- This happens in the thykaloids, where pigment molecules reside like chlorophyll.
- Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.

Answer:
Leaf cells contain chloroplasts. Photosynthesis happens in the chloroplasts as they hold vitality from the sun. Chloroplasts contain chlorophyll, which influences leaves to seem green.
The tissues of the leaf in the middle of the epidermal cells, into which gases diffuse from the stomata, are called mesophyll. The mesophyll can be additionally separated into two layers, the palisade layer, and the springy layer, both of which are stuffed with chloroplasts, the production lines of photosynthesis.
