Answer:

Nerve agent

Explanation:

A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.  

On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.

These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.

pav-90 [236]

Answer:

Option A, Glucose metabolism in the fetal brain increased

Explanation:

Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active

Hence, option A  is correct

During this stage, children are now capable of thinking in a more logical manner and their moral judgement has become subjective as <u>they now center on the motives of wrongdoers as well as on the amount of damage done when assigning blame</u>. For instance, they are able to judge another child according to the amount of damage she/he has done and whether it was done in purpose or accidentally.

Elan Coil [88]

The true statement about the relationship between true moss sporophytes and gametophytes is: (d) Sporophytes are parasites of gametophytes.

Sporophyte is the part of the life cycle in plants where the plants are asexual and in diploid phase of their life. The plants produce spores during this stage. In vascular plants sporophyte is the dominant stage of life.

Parasites are the organisms that live inside or outside an organism and depend upon that organism for their food as well. Apart from extracting food, the parasites also provide some kind of harm to the host they live in. Sporophytes are called parasites because they directly developed from the fertilized egg in archegonia.

The given question is incomplete, the complete question is:

Considering that the mature sporophytes of true mosses get their nutrition from the gametophytes on which they grow, and considering these generations as individual plants, what is true of the relationship between true moss sporophytes and gametophytes?

a. Sporophytes are endosymbionts of gametophytes.

b. Sporophytes are mutualists of gametophytes.

c. Sporophytes are commensalist of gametophytes.

d. Sporophytes are parasites of gametophytes.
