Answer: Option B. 1. photosystem II 2. photosystem II 3. photosystem I
Explanation:
Photosynthesis is the process by which plants make their own food in the presence of light utilizing carbon dioxide and water. this process occurs in chloroplast which contains green pigments called chlorophyll.
Photosystem are defined as the cluster of chlorophyll pigments found on the thylakoid membrane ( in chloroplast) which functions to collect energy and concentrate it to reaction center which further uses the energy to excite electrons and pass on to enzymes.
Photosystem II absorbs light and energy which allows the excitation of electrons and creates an electron deficiency in Photosystem II. the deficiency filled by Z protein which contain manganese that stimulates splitting of two water molecules.
NADPH formation takes place in Photosystem I. Photosystem I accepts energy from light which excites an electron and passed on to an electron acceptor called FeS. FeS then passes its e- to Ferrodoxin which donates its electron to NADP+ reductase. NADP+ reductase donates electron to NADP+ and add a proton to form NADPH to get stabilized.
Hence, the correct option is B.

B

The right answer is A patient who is Rh– can receive only Rh– blood.
The blood group is not the only thing that matters, it adds a category: rhesus. Rhesus refers to a red blood cell antigen that is on their wall. There are two blood group systems: Rh positive (Rh +) and Rh negative (Rh-).
Rhesus is positive in people who have this antigen. It concerns the majority of the population. Negative rhesus refers to people without the antigen. This rhesus factor is especially useful to know if a blood transfusion is feasible between two people.
The blood transfusions can be "iso-rhesus", that is to say between Rh + and Rh- but only in one sense: Rh- can give to Rh + but Rh + can not give to Rh-. Again because of the presence of antibodies directed against the antigen in Rh- people.

Answer:
The correct answer is minority influence.
Explanation:
According to the concept of minority influence, the smaller groups will affect the individuals on the basis of their opinions and perspectives on the topics, which are not witnessed by many. They develop a perception, which is not common and majorly are from their observations of the things, which are required to get better in the humanity and community.
