Which statement is NOT true about the noncyclic electron pathway? (A) Electrons are boosted to higher energy level in Photosystem I.
(B) Sunlight excites electrons in Photosystem II.
(C) It produces ATP.
(D) It produces NADPH.
(E) It produces carbohydrates through carbon dioxide fixation.

Answers

Answer:

The correct answer will be option E.

Explanation:

The non-cyclic pathway or electron transport chain is the pathway which takes place in the light reaction.  

The non-cyclic pathway starts from the PSII or P680 when the sunlight excites the electrons form the from the photosystem. This high energy electron is transferred to the higher energy level and loses its energy on the path.  

The lost energy is used to form the ATP and NADPH which are used later in the formation of glucose during the dark reaction.

Thus, option E is the correct answer.

Final answer:

In the noncyclic electron pathway of photosynthesis, electrons are not boosted to a higher energy level in Photosystem I.

Explanation:

The statement that is NOT true about the noncyclic electron pathway is (A) Electrons are boosted to higher energy level in Photosystem I.

The noncyclic electron pathway is an important part of the light-dependent reactions of photosynthesis. In this pathway, electrons from photosystem II are excited by sunlight and transferred to photosystem I, where they are further excited to a higher energy level. This pathway ultimately produces ATP and NADPH, which are then used in the light-independent reactions to produce carbohydrates through carbon dioxide fixation.

In a population of seals, most of the seals have similar coloring. However, one seal has albinism. This seal is white and is almost completely blind. What is most likely the cause of this difference from the rest of the population?

Answers

The answer is gene mutation.

Albinism is a congenital disorder characterized by a complete or partial absent of pigment in skin, eyes or hair. It is a recessive disorder, which means that parents must not have the disorder. But if both of them carry a recessive allele, and offspring inherit the recessive alleles from mother and father, the offspring will have albinism. Anyway, it is pretty rare, since it is the recessive trait, and most of the offspring will have normal coloring.

The vultures do not have hair on their heads? explain

Answers

They have bald heads and usually don't have feathers on their necks, either. Bare skin in those areas helps them stay cleaner why they stick their head into a carcass to feed. With no feathers to trap gunk  on a vulture's head, meat and blood just dry and flake off. Vultures are able to eat rotting food because they have a strong immune system. And they play a super-important role in our environment as a clean-up crew!

Suppose that the farmer is growing rice crop. If he bought 5 kg seeds at Rs. 100 per kilogram, then how much net money will he get after selling 1000 kg of rice grains in the market at Rs.40 per kilogram?

Answers

Answer:

The net money the farmer will get

= Rs. 39,500

Explanation:

The farmer bought 5 kg seeds of rice at Rs. 100 per kg.

Cost price = 5 × 100 = Rs. 500

And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg

Selling price = 1000 × 40 = Rs. 40,000

The farmer's net profit

= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500
