Answer:
The first box would be the pH will decrease, and the acidity will increase, and for the second box, the pH will increase, and the acidity will go down.
Explanation:
As the hydronium concentration increases, the pH decreases, and therefore if the hydromnium concentration decreases, the pH will increase. pH is sort of backwards, as the level increases, the acidity will go down, and as it decreases, the acidity will go up.
when the concentration decreases, the pH level increases, therefore causing it to become more basic/alkaline (acidity decreases)

the difference between prokaryotic and eukaryotic gene regulation
Answers
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.
This food web represents a community in a rain forest.
If the beetles disappeared from this community, which changes would be
likely to occur? Select the three correct answers.
A. An increase in the number of strangler figs
B. A decrease in the population of sloths
C. A decrease in the number of boa constrictors
D. An increase in the population of fruit bats
E. A decrease in the population of poison dart frogs
Answers
Answer:
A, C, E
Explanation:
If the beetles disappeared from this community, changes likely to occur include
an increase in the number of strangler figs, an increase in the population of fruit bats and decrease in the population of poison dart frogsThe beetles are insects which eat up strangler figs and a decrease mean an increase in its number.
The population of fruit bats will increase as they will have more strangler figs available for food.
Poison dart frogs will decrease because they feed primarily on beetles in the ecosystem.

Why does evolutionary theory absolutely require the earth to be very
old?
Answers
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!

Answers
Answer:
An aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain
Explanation:
It's aerobic because there is oxygen available while if it were anaerobic, no oxygen would be present.
Hope it helps :)
Natasha is making a model of cellular respiration. Her model shows the pathway followed when there is enough oxygen available, so her model shows it is an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain, which is option C.
What is the significance of respiration in living beings?Cellular respiration is either carried out when there is an abundance of oxygen, called "aerobic respiration," when there is enough oxygen present to lead to the running of the glycolysis, Krebs cycle, and electron transport chain to form energy, which is in a normal condition of a cell. while fermentation takes place when oxygen is not enough.
Hence, Natasha is making a model of cellular respiration. Her model shows the pathway followed when there is enough oxygen available, so her model shows it is an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain, which is option C.

Answers
Answer:
A.) Are extinct
You should mark me brainliest because I think I'm cool
Index fossils are usually defined as those fossils that were present on earth for a very short period of time. They were very broadly distributed in almost all parts of the world. They were comparatively smaller in size and comprised of hard parts that were preserved under favorable conditions which are found at many places in the present. These are extinct species. For example, trilobites and ammonites.
These index fossils are very useful because it helps in determining the age of the fossils as well as rocks by applying the radioactive dating method.

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.
Answers
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.

Answers
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.
