Answer:
The correct answer is option C. "Self-dispatch is encouraged in mutual aid systems".
Explanation:
It is false to affirm that self-dispatch is encouraged in mutual aid systems. Mutual aid systems are agreements that let resources assistance across jurisdictional boundaries under emergency situations. Therefore, self-dispatch is not encouraged in mutual aid systems. On the contrary, it is encouraged that the resources request for assistance of other jurisdictions under an emergency situation.
Speciation is the creation of a new species distinct from the original due to evolution.
I will walk through how this will work for you.
1. Animals of the same species living on either side of a stream can move from one side to another.
2. The stream changes into a river
3. Animals are now separated and must live apart
4. Environments on either side of the river change over time.
5. Animals due to natural selection, undergo change
6. After a thousands of years, two different of species form.
Hope this helps.
Answer:
B. increase the carrying capacity of the cell
Explanation:
Answer:
Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
Explanation:
The negative feedback principle in human physiology is involved in this case. The inciting factor here is the increase in blood glucose that will be recognized by the pancreatic islet cells (the endocrine part of the pancreas) and will signal insulin release. Insulin upregulates glucose transporter proteins in cells, especially muscle cells, which will then stimulate glucose uptake from blood. Insulin also stimulates glycogen formation in the liver. These events will subsequently lower blood glucose and low blood glucose will now inhibit the insulin secretion by the pancreas. In the event of hypoglycemia or dangerously low blood glucose, the first adaptive mechanism of the body is to produce glucagon from the pancreatic islet cells. Glucagon will stimulate glycogen breakdown in the liver and therefore raise blood glucose levels to normal.<span> </span>
