Answer: <u>Option Only anti-A antibodies are present.
</u>
Explanation: In a blood group type, antigens are present of the same blood type and antibodies for the other. For example, blood A type will have antigens A but antibodies would be anti-B. Similarly, in blood type B, antigens would be B, but antibodies would be anti-A. Both anti-A and anti-B are present in blood type O. And in blood type AB, none of them is present.
The answer is b) proteins because amino acids are the monomer of proteins. Many amino acids are joined together in what is known as a polypeptide chain, which forms a protein :)

Early land plants like mosses did not have vascular tissue. They must absorb their water directly from their surroundings, such as growing on rocks or trees that are moist. You find mosses in damp areas for this reason. They cannot grow in drier climates because they cannot pull water from the ground like vascular plants. Ferns are also suited to reproduce in more moist/humid climates because water must be present for their gametes (sperm and eggs) to find one another for fertilization. Seeds are adaptations by angiosperms and gymnosperms that allow for waterless fertilization. Either wind or animal pollinators help spread pollen and help the sperm reach egg cells for fertilization to occur. For that reason, these plants are better suited to survive in drier, modern climates.

Answer No 1:
<u>Chloroplasts in the leaves</u> are The part of plants that contains structures
needed to absorb sunlight and carbon dioxide.
Answer No 2:
The <u>Chloroplast </u>cells inside this structure contain many green
organelles called<u> chlorophyll</u>.
Answer No 3:
Inside each of these organelles are stacks of <u>thylakoid </u> that
contain the green pigment.
Answer No 4:
<u>Chlorophyll</u> absorbs sunlight needed to power the light dependent reactions of photosynthesis
Explanation:
The process of photosynthesis can be described as a series of reactions in which carbon dioxide and water are converted in to food i.e glucose in the plants. Oxygen is the by product of this reaction. Certain reactions of this process occur in the presence of light and are termed as light dependent reactions. The reactions which do not require light are termed as light independent reactions.
The process of photosynthesis occurs in the leaves. Leaves have structures called chloroplast where photosynthesis occurs. The chlorophyll are present inside the chloroplast which rap the sun's light energy.
