what's the importance of microscope in the study of animal
Answer:
It is important because biology mainly deals with the study of cells, genes, and all organisms. Some organisms are so small that they can only be seen by using very strong magnifications, which can only be achieved by a microscope.

How do mutations happen?
Answer:
HOPE THIS HELPS
Explanation:
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke
Explanation:
would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.
If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.
When someone says they have a "fast" metabolism, they are referring to the fact that they are able to efficiently
break down complex molecules at a higher rate than the average person.
Which of the following answer choices best describes someone with a "slow" metabolism?
Choose 1 answers
Low rate of catabolism
Low rate of anabolism
High rate of catabolism
Equal rates of catabolism and anabolism
Answer:
CORRECT (SELECTED)
Low rate of catabolism
Explanation:
Someone with a "slow" metabolism would have a low catabolic rate because their ability to break down complex molecules occurs at a slower, less efficient rate than someone with a "fast" metabolism.

Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
b. False
Answer:
Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
Explanation:
A woman's estrogen levels become highest towards the end of her ovulation. At this point, the woman is naturally prepared for a possible pregnancy. The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women. By the end of the luteal phase, the corpus luteum function declines.

Which statement describes the function of nucleic acids during the synthesis of proteins ?
Answer: sheesh
Explanation cuz i said
Fiona wants to use the scientific method to answer the question “Do oxygen levels in the air affect rates of photosynthesis?” She reads about photosynthesis in her biology book and is ready to carry out the next step. What should she do next?
perform an experiment
design a procedure
make observations
form a hypothesis
The first thing Fiona, or anyone, should do is form her hypothesis.
The hypothesis is your own proposed explanation for whatever phenomenon you're trying to study. Think of it as a predetermined idea of what could happen based on what you already know.

Henry is a forensic scientist who works in the lab. He has to process evidence that was collected by the field officer. Henry knows that the field officer believes the perpetrator was the victim’s best friend, and has collected evidence to prove such. Which two types of bias affect this investigation? Henry believes that bias might be present, because the field officer selectively collected evidence. He also believes that is present, because the field officer has come to a conclusion before the evidence is processed.
1st- Selection bias, 2nd - expectation bias

how can blood be stored much longer
Answer:
Whole blood can be stored at 4–8°C for up to 24 hours before the serum is separated, but it must not be frozen. Whole blood should be allowed to clot and then centrifuged at 1000 × gravitational units (g) for 10 minutes to separate the serum.
hope this helps

Explanation:
are atrophies considered producers or decomposers
Answer:
decomposers
Explanation:
The PO2 and PCO2 of blood leaving the lungs is kept remarkably constant. This homeostasis is maintained by adjusting the magnitude, or volume, of respiration. Thus, it follows that changes in the magnitude of respiration are influenced by changes in P_O2 and P_CO2 in the body.
Of these two gases, changes in ____(1)___ are the most important in regulating the magnitude of ventilation. A rise in the partial pressure of this gas triggers the body to __(2)____ the magnitude of ventilation. Which of the following statements correctly describes the major mechanism by which this has is monitored?
(1) PO2 or PCO2
(2) decrease or increase
A. Peripheral chemoreceptors in the carotid arteries monitor changes to CO_2 levels in the arterial blood.
B. Peripheral chemoreceptors in the carotid arteries monitor changes to P_CO2 levels in the arterial blood.
C. Central chemoreceptors in the medulla monitor changes to H^+ levels in the extracellular fluid
D. Central chemoreceptors in the medulla monitor changes to CO_2 levels in the extracellular fluid.
Answer:
1. Partial pressure of Carbon dioxide or PCO₂
2. A rise innthe partial pressure of Carbon dioxide triggers the body to increase the magnitude of ventilation.
A. Peripheral chemoreceptors in the carotid arteries monitor changes to CO2 levels in the arterial blood.
Explanation:
Breathing or ventilation refers to the process by which the gases oxygen and carbon dioxide are exchanged in the body through the lungs.
The most important function of breathing is to supply oxygen to the body as well as the removal of the the carbon dioxide produced in the body during respiration. Since oxygen and carbon dioxide are both gases, their concentration in the lungs are given as their partial pressures. The partial pressure of carbon dioxide (PCO2) in the lungs, or its concentration in the body, controls the magnitude or rate of respiration.
The peripheral chemoreceptors located in the carotid arteries detect and monitor changes in the levels of carbon dioxide in the arterial blood. An increase in arterial levels of CO2 when detected, is passed as signals from the peripheral chemoreceptors along nerves to the respiratory groups of the respiratory center, which then induces an increase in the movement of the respiratory muscles especially the diaphragm. Thus, respiration rate is incresed to remove CO2 and bring in oxygen.
