Vitamins are organic food substances required by man man and other animals only in small amounts for normal growth and healthy development.

The main vitamins are vitamins A , B, C, D, E and K.

Deficiency of vitamin A causes Night blindness

Deficiency of vitamin C causes scurvy.

Vitamin D is required for strong bones and teeth.

Cereal Z is recommended for the children because of its high vitamin D content.

The absence of which of these will not affect photosynthesis is - oxygen, Carbon dioxide, water, Chlorophyll, light. Give reason
In-s [12.5K]

Answer:

Oxygen

Explanation:

Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).

Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.

Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.

Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)

Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.

Light is needed as a source of energy to energise the electrons

3. How can we use what we know about cell membranes to treat disease
Amiraneli [1.4K]

We use cell membranes to treat disease because the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.

<h3>What is the cell membrane?</h3>

The cell membrane is a thin lipoprotein film formed by phospholipids and proteins delimiting the cytoplasm of all types of cells. They prevent invading microorganisms from attaching to the cell and replicating.

Then, using the concepts of cell membrane, we can use them to prevent viral diseases from occurring since the virus cannot fix itself to replicate. So in this case, the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.

Zarrin [17]

The answer is B)<span> </span>temporal isolation.

<span>
<span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>
