The correct answer is option C, that is, it prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.
The herbicide atrazine combines with the D1 protein and inhibits the binding of plastoquinone. By obstructing the binding of plastoquinone, the procedure of photosynthetic transfer of electron is disturbed, and thus, the production of ATP and NADPH in the chloroplast gets compromised.
This leads to an incapacity to fix carbon dioxide and generate the nutrients required for the plant to live. The block in the transfer of electrons also results in an oxidative stress and the production of radicals that lead to brisk cellular destruction.
Consciousness is defined as the state of awareness of self and the environment. Another way of describing it is a condition for which a person is capable of perceiving stimuli from the environment and responding appropriately.
The consciousness system has two principal functions:
1) Maintenance of waking state (arousal or level of consciousness)
2) Content of experience (awareness or content of consciousness)
It is important to understand the difference between these two. Arousal shows the wakefulness of one person and awareness is the person ability to perceive the environment. In vegetative state, ones are awake but unaware of themselves or the environment.
In this article, we will look into the concept of neuronal system involved in consciousness system. It is crucial to realize that detail discussion is beyond the scope of this article and only essential and relevant elements to the
Answer : Option A) He asked what would happen if he deliberately inoculated someone with cowpox fluid from another person.
Explanation : Edward Jenner wanted to know what would happen if he deliberately inoculate the cowpox fluid from some person to another. He tested this experimental results and later on came up with the hypothesis. Which roughly state that someone will not get smallpox because they already had cowpox.
