Which table correctly describes the functions of the cell structures
listed
HELP ME PLEASE
Answers
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.

Which scenario would result in a decrease in population size, or a negative population growth?
Use this formula:
population growth = (birth rate + immigration) – (death rate + emigration)
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate
Answers
Answer:
The third situation has the lowest amount of people with 0.
Explanation:
In this situation,
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate. Population growth = 14
In this one,
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate Population growth = 2
For this one,
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate Population growth = 0
Last one,
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate Population growth = 2.

A. Layers that cut across the most other features are youngest.
Explanation:
Using the principles of cross-cutting relationships, you can determine the relative age of rocks found in the ground. The idea behind it is that the geologic feature which cuts another is the younger of the two features, and it had been around for 400 years. It's not very precise but it is good for determining relative age.

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).
Answers
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.

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.
Answers
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.
what are the many forms of energy? how is energy either potential of kinetic
Answers
Answer:
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
You need energy to do any work, which is why the ability to do any work is energy. Read that again. Potential and kinetic energy are two forms of energy that can be converted into each other. Potential energy can be converted to kinetic energy and vice versa.

Explain why harmful mutations tend to disappear, while beneficial mutations become
widespread.
Answers
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!

If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).
