Humans produce the enzyme amylase. This enzyme breaks down starch, a
complex carbohydrate found in many food sources (e.g. potatoes, breads).
Explain why the human digestive system is unable to use amylase to break down
the complex carbohydrate cellulose, which is also found in some foods (such as
celery).
Explanation:
We lack the enzyme cellulase which is the enzyme required to break down cellulose.
Base on the given information, human can produce the enzyme amylase, but cannot produce the appropriate enzymes that is able to breakdown the beta acetal linkages that exist in cellulose.
Enzymes serves as biological protein, and it is needed in the body to carry out specific functions.
Human posses amylase which made it possible to breaks down starch that is contained in many carbohydrate food that we eat.
We can conclude that human doesn't have the enzymes that that act on complex cellulose contain in found like celery.

If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called --
Answer:
Hypertonic solution
Explanation:
A hypertonic solution is where the concentration outside of the cell is greater when compared to the inside of the cell.
If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called - hypotonic solution.
Hypotonic solution is the one that contains more concentration as compared to the concentration in the cytoplasm of cells. It means that a solution contains more water as compared to the water within the cell.
molecules move from their higher concentration to their lower concentrationIt is called osmosisWater molecules always try to balance their concentration on both sides.When an animal cell, such as a red blood cell, gets water to the hypotonic solution, it swells.Thus, If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called - hypotonic solution.

Which table correctly describes the functions of the cell structures
listed
HELP ME PLEASE
Answer:
The correct answer is - cell membrane - regulates cell contents.
Explanation:
Various cell structures have different cellular functions in the cells. The major function of the chloroplast is to produce sugar with the help of chlorophyll pigment by trapping the sunlight. The mitochondria perform cellular respiration and convert sugar to energy.
The vacuoles are the cell structure that helps in maintaining water balance and also store nutrients and sometimes help in waste disposal, however, it is not its major function. The cell membrane is the cellular structure and barrier that regulate what cell content will move outside the cell and what will enter.

1. If x and y vary inversely and x=3 when y=8, find y when x=4*
Oy=12
Oy=6
Oy=5
y=2
If x and y vary inversely and x=3 when y=8, then y will be 6 when x=4. Therefore, option (B) is correct.
What is the value of Y?If x and y vary inversely, it means that their product remains constant. Mathematically, we can write this as x * y = k, where k is a constant.
We are given that x = 3 when y = 8. Using the formula above, we can find the value of k:
x * y = k
3 * 8 = k
k = 24
Now we need to find y when x = 4. Again, using the formula above:
x * y = k
4 * y = 24
y = 6
Therefore, the option is Oy=6.

An EMT reaches the scene of a car accident, disinfecting and dressing a man's head wound that has been bleeding profusely. Upon taking off his bloodied latex gloves, he notices that a shard of window glass has penetrated one glove and cut is palm. Years later, long retired after a second career as an accountant, he is surprised to discover that he has liver cancer. Thinking back, he recalls having received both hepatitis vaccines available at the time of the exposure, and guesses that he may most likely have been exposed to __________.
Answer: hepatitis C.
Explanation:
Based on the information given in the question, it's most likely that the person has been exposed to hepatitis C.
Hepatitis C is an infection that is caused when a virus attacks the liver which leads to the inflammation of the liver. Since the person reaches the scene of a car accident, it's possible that the EMT got in contact with the contaminated blood. In this case, he most likely have been exposed to hepatitis C.

By what means has the overuse of antibiotics in medicine and agriculture lead to the current global problem of antibiotic resistance?
The overuse of antibiotics significantly increases the bacterial mutation rate, causing more antibiotic-resistance mutations to occur.
Humans develop an immunity to antibiotics, rendering them ineffective.
Indiscriminant use of antibiotics selects for resistant bacteria and increases their numbers.
Antibiotic resistance is a fabricated problem used to sell newer and more expensive antibiotics.

Why is an imbalanced high population of moose on the island seen as a
problem? *
If the moose population continues to grow, they will run out of space on the island and
take over the wolf niche.
If the moose population is unchecked, the local balsam fir population will be
decimated, leaving a barren ecosystem.
It was not seen as a problem; science believes we should let the ecosystem run its
course and dies out.
It was not seen as a problem because the absence of wolves on the island ensured
the future of the ecosystem.
Answer:
If the moose population is unchecked, the local balsam fir population will be decimated, leaving a barren ecosystem.
Explanation:
The imbalanced high population of moose on the island seen as a problem because it decreases the local balsam fir population which is a major food source for the moose in the winter season. If the population of moose is grow higher then the scarcity of food sources occurs and the food source will be eliminated from that ecosystem. If the moose population increases the local balsam fir population will be eliminated from the ecosystem and the land will remain barren or without vegetation.

Explain why harmful mutations tend to disappear, while beneficial mutations become
widespread.
Answer:
Harmful mutations don't accumulate over time because they reduce the reproductive success of an organism! These mutations would be dead before they can produce any offspring, so there's a slim chance of their genes being passed on. (So it's basically like survival of the fittest, the ones that survive usually have beneficial mutations because that's what keeps them alive lol) Beneficial mutations play a big role in evolution too!
