the difference between prokaryotic and eukaryotic gene regulation
Answer:
READ THIS
Explanation:
To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level.
Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm. The regulation of gene expression can occur at all stages of the process (Figure 1). Regulation may occur when the DNA is uncoiled and loosened from nucleosomes to bind transcription factors (epigenetic level), when the RNA is transcribed (transcriptional level), when the RNA is processed and exported to the cytoplasm after it is transcribed (post-transcriptional level), when the RNA is translated into protein (translational level), or after the protein has been made (post-translational level).
Answer:
Prokaryotic gene expression is primarily controlled at the level of transcription. Eukaryotic gene expression is controlled at the levels of epigenetics, transcription, post-transcription, translation, and post-translation.

Why does evolutionary theory absolutely require the earth to be very
old?
Answer:
Because it takes time for the animals to adapt to their environment, and change their DNA
Answer:
Because evolutions don't happen overnight, it takes years and years for an organism to develop an evolution. So, the earth has to be old, because if we look at the earth when it was young, then we don't really see any evolutions. However, if we look at it when it's old, we can see that there were many evolutions. I hope this helps!
Explanation:
Most of the water vapor in the atmosphere comes from evaporation of water from oceans. Most of this evaporation occurs where there is the greatest solar radiation, which is - Group of answer choices around islands in the Pacific. along the coast of Europe. near the Equator.
Answer:
near the Equator
Explanation:
The part of the Earth that receives the most amount of solar radiation is always near the Equator. This is because the Earth itself revolves around the run in a tilted motion, since the Earth is round this makes the Equator always closest to the sun which means it will always get the most direct amount of Sun Radiation. This radiation causes more heat which ultimately causes a greater amount of water to be evaporated in this location.

Name and describe the five types of active transport systems.
Answer:
Please Mark as Brainliest. Please!!!!!!!!!!
Explanation:
Definition
Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active transport is required.
Active transport requires energy to move substances from a low concentration of that substance to a high concentration of that substance, in contrast with the process of osmosis. Active transport is most commonly accomplished by a transport protein that undergoes a change in shape when it binds with the cell’s “fuel,” a molecule called adenosine triphosphate (ATP).
For example, one type of active transport channel in the cell membrane will bind to the molecule it is supposed to transport – such as a sodium ion – and hold onto it until a molecule of ATP comes along and binds to the protein. The energy stored in ATP then allows the channel to change shape, spitting the sodium ion out on the opposite side of the cell membrane. This type of active transport directly uses ATP and is called “primary” active transport.
Another type of active transport is “secondary” active transport. In this type of active transport, the protein pump does not use ATP itself, but the cell must utilize ATP in order to keep it functioning. This will be explained in more depth in the section on Symport Pumps below.
Lastly, active transport can be accomplished through processes called endocytosis and exocytosis. In exocytosis, a cell moves something outside of itself in large quantities by wrapping it in a membrane called a vesicle and “spitting out” the vesicle. In endocytosis, a cell “eats” something by wrapping and re-forming its membrane around the substance or item.
Each type of active transport is explained in more detail below.
Types of Active Transport
Antiport Pumps
Antiport pumps as an example of active transport
Active transport by antiport pumps
Antiport pumps are a type of transmembrane co-transporter protein. They pump one substance in one direction, while transporting another substance in the opposite direction. These pumps are extremely efficient because many of them can use one ATP molecule to fuel these two different tasks.
One important type of antiport pump is the sodium-potassium pump, which is discussed in more detail under “Examples of Active Transport.”
Symport Pumps
Symport pumps take advantage of diffusion gradients to move substances. Diffusion gradients are differences in concentration that cause substances to naturally move from areas of high to low concentration.
In the case of a symport pump, a substance that “wants” to move from an area of high concentration to low concentration down its concentration gradient is used to “carry” another substance against its concentration gradient.
One example of a symport pump – that of the sodium-glucose transport protein – is discussed below under “Examples of Active Transport.”
Sympoter pump as an example of active transport
Active transport by symporter pumps
Endocytosis
In the third type of active transport, large items, or large amounts of extracellular fluid, may be taken into a cell through the process of endocytosis.

Which effect does the sun's energy have on a comet?
A. It causes the comet to form a bright tail.
B. It causes the core of the comet to melt.
C. It causes the comet to turn toward earth.
D. It causes the comet to break apart.
Answer:
The answer is B because the sun melts the core of the comet
The sun's energy causes the comet to form a bright tail. The correct answer is A.
When a comet approaches the Sun, the Sun's energy causes various effects on the comet.
As the Sun heats up the comet, it causes the icy nucleus of the comet to vaporize and release gas and dust into space.
This process is known as outgassing. The released gas and dust form a glowing envelope called a coma around the nucleus.
Additionally, solar radiation and solar wind push the released gas and dust away from the comet, forming a glowing tail that points away from the Sun.
So, the correct option is A.
