Answer:
TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine. A person with TB can die if they do not get treatment.
In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.
Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).
Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.
I really hope this helps!
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.
The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.

What are herbicide?</h3>
Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.
This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.

Answer:
The correct answer is option A, that is, stimulate smooth muscle contraction.
Explanation:
A group of lipids and a hormone that plays an essential role in monitoring the process of the formation of blood clots, stimulation of labor, the flow of blood and inflammation is known as prostaglandins. The hormone prostaglandin takes part in various kinds of body functions like the relaxation and contraction of the smooth muscles at the time of childbirth, monitoring blood pressure, dilation and constriction of blood vessels, and produce inflammation at the site of infection or tissue damage.
Prostaglandins possess five-membered rings and are obtained from the fatty acid, arachidonic acid. At the time of blood vessel injury, thromboxane, that is, a form of prostaglandin enhances the process of blood clot formation so that the injury site gets heal quickly.
