During the rock cycle, rocks get broken apart by weathering, carried along by erosion, and eventually deposited in a body of water. What happens next?

Answers

After many years of pressure and possibly heat it will be compressed back into a form of rock such as sediment.

Compaction and cementation into sedimentary rock, then heat and pressure into metamorphic rock. this is correct answer

Which structures on the ocean floor are equivalent to the mountains on land

Answers

Answer;

-the continental shelf, slope, and trenches;


The continental shelf, slope, and trenches are the structures on the ocean that are equivalent to the mountains on land.


Explanation;

-Continental shelf is that shallow part of the ocean floor that begins at the shoreline and gently slopes underwater to an average depth of about 430 feet. It is normally covered with thick layers of sediment.

-Continental slope begins at the edge of the continental shelf and plunges down to depths of over two miles and are covered with thick layers of sand, mud and continental shelf.

-Ocean trenches are very deep and similar to canyons on land.

The continental shelf, slope, and trenches are structures on the ocean floor are equivalent to the mountains on land.
Continental shelf is the landmass underwater. It extends from a continent and results in an area of  shallow water known as a shelf sea. The shelf brake, or the slope is the point where the continental shelf ends. 
The ocean trenches topographic features on the sea floor, formed when one tectonic plate slides beneath another.

The scientific name for a white oak is Quercus alba; the scientific name for a red oak is Quercus rubra. What does this tell you about the organism? A. Red oaks are grouped in the genus alba.
B. White oaks are grouped in the genus Quercus.
C. White oaks are grouped in the same species category as red oaks.
D. Red oaks are grouped in the species Quercus.

Is it B????

Answers

The answer is B. White oaks are grouped in the genus Quercus. 

According to binomial nomenclature, a formal system of naming species, a name of species is composed of two parts. The first word indicates the organism's genus classification, the second word indicates the species within a genus. So, the first word Quercus indicates the genus in both cases, the second word alba or rubra indicates species within the genus Quercus.

A. is not the right answer because alba indicates species name, not genus name.
C. is not the right answer because white oaks and red oaks are different species, but the same genus.
D. is not the right answer because Quercus is not species but genus.
The answer to the question stated above is letter B.White oaks are grouped in the genus Quercus. 

The scientific name for a white oak is Quercus alba; the scientific name for a red oak is Quercus rubra. This simply implies that 
White oaks are grouped in the genus Quercus.

Answer:

it's really simple, all you need to do is look at the periodic table. for example, group 1A has 1 valence electron. 2A has 2, 3A has 3, and so on.

Explain the difference between an infection caused by a fungus and an allergy caused by a fungus

Answers

Re-posting some old information I found on this website

When a fungus infects a body, it attacks the host by destroying and often taking over cells. When a person has an allergic reaction (to anything) the substance triggers the body to send histamines and excess water to the affected area, swelling and closing the area to prevent infection. - Answer Provided by ChaoticPiece

What would happen if there were no enzymes in the human body? Explain your answer.

Answers

Enzymes are in our bodies to speed up reactions etc. If there were no enzymes, then our bodies would act very slowly to reactions. 

Final answer:

Without enzymes, the body couldn't perform essential chemical reactions quickly enough to sustain life. Enzymes also aid digestion and help in immune defence. Their absence would critically interrupt bodily functions and overall health.

Explanation:

If there were no enzymes in the human body, many essential biological processes would be negatively impacted. Enzymes act as biological catalysts, speeding up the chemical reactions that occur within cells, thereby allowing life-sustaining processes to occur at the rate necessary for life. If we didn't have enzymes, these reactions would happen too slowly to sustain life, or might not happen at all.

Enzymes are vital in breaking down food and converting it into usable energy. Without enzymes, our digestive system would not be able to efficiently break down nutrients, leading to malnutrition and energy deficiency. Moreover, enzymes are involved in the immune system's defence mechanisms. They assist in the destruction of foreign pathogens, thus protecting the body from infections.

Furthermore, each cell's enzyme demand changes according to its needs and role within the body. For instance, the enzymes necessary in stomach cells differ from those in skin, blood, or nerve cells reflecting the diverse functions enzymes perform in the human body.

Overall, without enzymes, the human body would be unable to function properly. They are essential for our survival, and their absence would dramatically alter the way our bodily systems operate.
