When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.

Answers

Answer:

C broken down into amino acids.

Explanation:

Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.

In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien

Answers

Answer:

B. generating more nerve cells

Explanation:

Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.

Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

Explain the differences between the three ways of heat transfer, conduction, convection, and radiation.​

Answers

Answer:

The differences between these three ways of heat transfer are that conduction is the transfer of thermal energy through direct contact, convention is the transfer of thermal energy through the movement of liquid or gas, and radiation is the transfer of thermal energy through thermal emission. As you can see, each way of heat transfer has a different way of moving through objects.

Why is this statement true?
O Hydrogen is a gas, but oxygen is a solid.
O Hydrogen atoms have a lower mass than oxygen atoms.
• Hydrogen atoms make up more of water's mass than oxygen atoms.
Hydrogen is present as single atoms and oxygen is bonded in compounds,

Answers

Answer:

Hydrogen atoms have a lower mass than oxygen atoms.

Explanation:

The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.

What is hydrogen?

Hydrogen is the most abundanet element representing nearly three quarters of the mass of the universe. Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter. Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).

Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table. Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.

Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.

Therefore, The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.

Give an example of how Eubacteria can be beneficial. Explain. Please help me. ​

Answers

Answer:

Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.

An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.

What are eubacteria?

The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.

Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.

Therefore,  Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

A. Cut the DNA into fragments of different sizes.
B. Compare the samples with a positive control.
C. Isolate DNA from the waterwakin question.
D. Stain the gel to reveal a banding pattern.

Answers

The last step to observe different DNA patterns is to stain the gel to reveal a banding pattern (Option D).

DNA extraction, polymerase chain reaction (PCR) and fragment separation by gel electrophoresis are basic molecular techniques used to identify patterns in DNA.

The patterns in DNA can be used for identifying an individual in a population, distinguishing different species, etc. These patterns can be obtained by using restriction enzymes.

There are different dyes used to stain DNA before the identification of patterns in DNA.

For example, ethidium bromide is a widely used dye to stain DNA before fragment separation by agarose gel electrophoresis.

In conclusion, the last step is TO STAIN the gel with a DNA dye to reveal a banding pattern (Option D is correct).

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose

A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made

Answers

Answer:

D)NADPH is made

A)ATP is used

Explanation:

Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]

The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:

Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).

Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis).

Conversely, the Calvin cycle regenerates ADP and NADP^+

How would the disappearance of shrimp, copepods, and amphipods affect the other organisms in the ocean food web

Answers

The disappearance of shrimp who cause whale numbers to decrease because they are a main food source for whales. And if copecods were to disappear it would cause a problem with microscopic algal cells and phytoplankton who’s populations would increase. And amphipods play an important role in marine and freshwater ecosystems. So if they were to disappear they would be more dead creatures around because they are scavengers and eat dead or decaying algae.
