Answer:
Explanation:
Depolarization occurs when the nerve cell reverses these charges; to change them back to an at-rest state, the neuron sends another electrical signal. The entire process occurs when the cell allows specific ions to flow into and out of the cell.
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 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

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.

6. Which of the following is the DNA sequence that a restriction enzyme binds to?
O A. Recognition site
O B. DNA Ligase
O C. Transfection
O D. Complementary sticky end
Answer: A
Explanation:
They recognize and bind to specific sequences of DNA, called restriction sites. Each restriction enzyme recognizes just one or a few restriction sites. When it finds its target sequence, a restriction enzyme will make a double-stranded cut in the DNA molecule.
(Also I think you meant Restriction sites, not Recognition sites.)

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.

Which plants are most likely to adapt successfully to a climate change in their environment?
O A) plants that grow rapidly
O B) plants that reproduce asexually
O C) plants that are cross-pollinated
OD) plants that do not rely on wind-pollination
Answer:
A
Explanation:
plants that grow rapidly
The plants that are most likely to adapt successfully to a climate change in their environment are ; ( B ) plants that reproduce asexually
The change in climate favors some plant species while negatively affecting other plant species. most plants depend on the climate/weather like the wind for its reproduction/survival.
Most plants are cross-pollinated while some are wind pollinated therefore they will require the right weather/wind conditions to adapt and survive in their environment, plants growing rapidly can be hindered by changes in climate conditions.
But plants that reproduce asexually do not rely on the climate conditions to carry out their reproductive activities which makes them the most likely to adapt successfully to a climate change in their environment.
Hence we conclude that The plants that are most likely to adapt successfully to a climate change in their environment are plants that reproduce asexually

Concentration cell based on the Ni2 -Ni cell reaction.
(a) Concentrations of Ni2 (aq) in the two half-cells are unequal, and the cell generates an electrical current and a voltage.
(b) The cell operates until [Ni2 ] is the same in the two half-cells, at which point the cell has reached equilibrium and the emf goes to zero.
Answer:
Explanation:
The missing diagram contained in this question is first attached in the image below.
The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.
From the information provided:
In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.
This causes Q(equilibrium constant) to equal 1 as well as log(Q) to equal 0, indicating that the cell is dead.
As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.

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.
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.
