Answer:
e.) If exposure to cowpox gives immunity to smallpox in milkmaids, then milkmaids have a natural immunity and their blood should be used to develop a smallpox vaccine.
Explanation:
- Milkmaids who suffered from cowpox did not suffer from smallpox i.e. they were immune to the disease.
- If milkmaids did not suffer from smallpox then there must be some element of immunity that they received once they had recovered from cowpox, this would likely be found in their blood as antibodies.
Explanation:
The answer is A.
When the body temperature returns to normal,the respiratory system sends a message to the skeletal system to stop shivering.
Coach Luke encourages his football team to wear biodegradable sneakers. The sneakers can be buried in the ground when they are worn out, and after many years, they will decompose like a plant. This condition conserves the environment.
<h3>What do you mean by Environment?</h3>
An environment may be defined as anything which is present in the surroundings of living entities that is either biotic or abiotic factor.
Chef Sonia uses disposable, nonbiodegradable kitchen towels in her kitchen. She uses them for everything from cleaning up spills to wiping her hands. She ends up using about two rolls in a month. This condition harms the environment because the towels are nonbiodegradable in nature.
The last situation conserves the environment because it utilized solar panels for energy production which is efficient in cost as well as helpful for the environment.
Therefore, each situation is mentioned above.

A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).
<h3>Mitogen-activated protein kinase :</h3>
A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.
In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.
Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.
The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.
