Answer:
Antigens, and epitopes.
Explanation:
Antigen is known as a substances which is capable of the causes an immune response in the body, and specifically activating white blood cells which are known as body's infection fighting cells. In general antigens are two types:
1) Foreign antigens or heteroantigens.
2) Auto-antigens or self antigens.
Epitopes are the part of an antigen which is recognized with the help of immune system, specifically by B cells, T cells, and antibodies. They are also called as antigenic determinants. The epitope is defined as the specific part of the antigen where an antibody binds.
Answer:
Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

The answer is ions, compounds & neutrons don’t really make sense & isotopes are different from everything this question is asking
Answer: Only options A, B, C and D are true statements
A) One sperm fuses with an egg while the other sperm fuses with the polar nuclei.
B) It results in the formation of a diploid embryo and triploid endosperm.
C) Both sperms involved in double fertilization form within the same pollen tube.
- The diploid nucleus resulting from the second fertilization undergoes meiosis to form the endosperm.
Explanation:
Double fertilization is a process that occurs in only flowering plants. It involves the following:
- A pollen grain produces TWO male gametes
- one male gamete fertilize the egg to form a zygote that is DIPLOID (with two basic sets of chromosomes)
- the second male gamete fuses with another cell named POLAR NUCLEI, to form endosperm (the food storing tissue) in the seed. The endosperm formed is TRIPLOID ( it has three sets of chromosomes), having undergone reductive division - meiosis
Thus, the options A, B, C and D are true statements
