Answer:
Structurally, proteins are different from carbohydrates because all proteins contain nitrogen (option C).
Explanation:
The basis of the chemical composition of proteins is carbon, hydrogen, oxygen and nitrogen, so all proteins have nitrogen in their structure. Some proteins also possess phosphorus and sulfur atoms, among others.
Proteins are biomolecules formed by the union of multiple amino acids through carboxyl-amino bonds, called petidic bonds. Their content of nitrogen and other atoms in their structure is what makes them different from carbohydrates.
The other options are not possible because:
Only some proteins contain iron in their composition.Potassium and helium are not part of the protein structure.Which molecule supply’s the energy for cellular functions
Answer:

1 In the picture above, do you expect the net flow of
chloride ions to flow in or out of the cell? Explain your
answer
Answer:
It should flow outside.
Explanation:
There are more of the chloride ions on the inside part than on the outside part of the cell so it would go to the outside.
The chlorine molecule will move from inside to outside of the cell.
What is membrane potential?
The molecules move from higher membrane potential to lower membrane potential. Diffusion via a semipermeable membrane leads to osmosis.
The solvent will tend to permeate from the less concentrated to the more concentrated solution if two solutions with varying concentrations are separated by a semipermeable membrane.
The name of this procedure is osmosis. Both processes are examples of passive transport at the cellular level.
Therefore, The chlorine molecule will move from inside to outside of the cell.

Which researcher proposed that dreams are a chance for problem solving? A. Sigmund Freud B. Matthew Wilson C. Rosalind Cartwright D. J. Allan Hobson
Answer:
The answer is Rosalind Cartwright.
Explanation:
A researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.
What is Problem-solving?Problem-solving may be defined as an instance of illustrating a problem that significantly determines the consequences of the problem along with identification, prioritization, and selection of alternatives for a solution; and implementing a solution.
Rosalind Cartwright was a neuroscientist who proposed the theory of dreams with respect to the chance for problem-solving. She hypothesized the complete mechanisms of dreaming which is particularly based on REM sleep. It is a way to process emotions, experienced during the day.
Therefore, a researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.

How is the difference in the walls of the atria and ventricle related to the different functions of the atria and ventricle?
Answer:
The atria are thin-walled sacs that receive blood from the body or lungs, while the ventricles have a thick muscular wall because they must pump the blood with greater pressure than the atria.
Explanation:
In the human heart, the atria and ventricles are responsible for handling blood and have different structures and function.
The atria are thin-walled sacs located at the top of the ventricles and their function is to receive the blood that comes from the whole body —right atrium— or from the lungs —left atrium— to pass it to each ventricle through the atrioventricular valves, which does not require much pressure. On the other hand, the walls of the ventricles are made up of a thick layer of muscular tissue, since the pressure with which they must pump the blood -towards the lungs or to the entire organism- is greater than that of the atria.The structure of each chamber of the heart is configured to be able to fulfill the specific function that they possess.

What shift in population growth has occurred by point A?
1 The birth and death rates are equivalent.
2 The rate of emigration equals the death rate.
3 The population sizes of the organism and its predator are equalized.
4 There will be more food available than the populations can consume.
The shift in population growth has occurred by point A is The birth and death rates are equivalent.
How does birth rate and death rate affect population growth?Population alteration is controlled by the balance between birth rates and death rates.
Suppose the birth rate stays constant and the death rate decline, then population numbers will increase.
whereas If the birth rate grow at a faster rate and the death rate stays the constant, then population will also increase.
Thus, option "A' is correct, The birth and death rates are equivalent.

What would happen if the Golgi bodies in the cell were destroyed?
The cell would not be able to digest or break down the materials left over from protein creation.
Explanation:
Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell. If this happened, the cell wouldn't be able to live for very long.

why might one type of coal contain more energy than another type of coal?
I think because of the strength of the coal, and the material. That makes a big difference, opinion wise.
Because it has a higher carbon content and/or a greater amount of other energy-rich components such as hydrogen and sulfur.
Why some coals have more energy than others?The amount of energy in coal can vary due to differences in the organic matter from which the coal was formed, such as the amount of plant material, the type of plants, and the amount of time the plant material was exposed to heat and pressure.
Additionally, the formation process of coal can also affect the energy content, with coal formed under higher pressures and temperatures typically containing more energy than coal formed under lower pressures and temperatures.

Essential nutrients move through a cell membrane by both passive transport and active transport. Which of the following correctly describes the transport of materials across a cell membrane?
Answer:
This question lacks options, the options are:
A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
B). Passive transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
C). Active transport moves nutrients from areas of high concentration to areas of low concentration without the use of chemical energy.
D). Passive transport moves nutrients from areas of low concentration to areas of high concentration without the use of chemical energy.
The answer is A
Explanation:
Transport of materials across a cell occurs via passive transport or active transport depending on whether energy input is required or not to facilitate the movement.
- Passive transport is the transport of materials e.g nutrients from areas of high concentration to areas of low concentration i.e down a concentration gradient, without the use of chemical energy (ATP).
- On the other hand, active transport requires chemical energy (ATP) to move nutrients from areas of low concentration to areas of high concentration i.e against concentration gradient.

How does greenhouse effect, affects biodiversity and gradual extinction
Answer:
Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze.
