A microscope is an instrument which makes an object appear bigger than it is. It took the invention of this relatively simple tool to lead to the discovery of cells<span>. In the 1660s, Robert Hooke began using microscopes to look at all sorts of materials. Anton van Leeuwenhoek took up similar work in the 1670s.</span>
Answer:
d) It is beneficial to the whole species, but not to all of the individual members.
Explanation:
This form of behavior raises the fitness of all the species at the expenses of each member.
Each member of the species performs altruistic behavior towards the queen and her progenies as it assist in creating of her nest to increase their generation numbers. Take for example, The workers do more of nurturing of the queen offspring instead of laying their own eggs. This altruistic behavior of workers promotes the further population of their species at the expense of them producing their own offsprings.

Here is the complete question:
Some species of wasps are social. The queen starts a colony from scratch each spring. She builds a small nest, and lays and raises a group of female workers. The workers enlarge the nest while the queen continues to lay eggs. Unfertilized eggs become males that mate with newly hatched females. All of the wasps except the newly fertilized females die by the summer.
Which best describes this behavior?
a)It is beneficial only to the males that do not fertilize eggs.
b)It is beneficial only to the female workers that are not fertilized.
c)It is beneficial to each one of the individual colony members.
d)It is beneficial to the whole species, but not to all of the individual members.
Answer:
Animals, including humans, store glucose in the form of glycogen.<em>(option 2)</em>
Hope it helps :)
Answer:
Here are some explanations from 0nline so if you want rewrite in your own words
hope this helps :))
blood glucose-
"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."
"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."
body temperature-
" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."
"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."
"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."
"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"
Im not really sure , but it might have something to do with polar chemical compound <span />
