A researcher is comparing sugar molecules that a cell takes in with amino acid molecules that the cell produces. Highlight all the statements that are true about amino acids but not true about sugars,
Always contain carbon
3. an input in glycolysis
C.typically contain nitrogen
D. can be used as an energy source
E can bond together to form proteins

Answers

Answer:

The correct statements for amino acids but not for sugars are :

C. typically contain nitrogen

E can bond together to form proteins

Explanation:

Both Sugars and amino acids always contain carbon molecules and both macromolecules can provide energy so are the source of the energy. Sugar molecule more specifically glucose molecule enters glycolysis during the cellular respiration process.

Amino acids always contain the nitrogen molecule in the structure along with carbon, oxygen, and hydrogen, there is a side chain present. Amino acids are the building blocks of the protein, peptide bonds are formed by amino acids together to make a poly peptide chain of a protein molecule.

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this: 6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy

Answers

The question is incomplete, the complete question is;

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2

cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

See explanation

Explanation:

If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.

Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.

Solid waste is stored in the colon until it is expelled from the body. This demonstrates that the excretory system working with which of the following systems? A circulatory B digestive C respiratory D muscular

Answers

Answer:

b

Explanation:

The solid waste that is stored in the colon until it is expelled from the body is a product of the digestive system, which is responsible for the breakdown and absorption of nutrients from food. Therefore, option (B) is correct.

What is digestive system?

The digestive system is a group of organs and structures in the body responsible for the breakdown of food into nutrients that can be absorbed and used by the body. The system includes the mouth, esophagus, stomach, small and large intestines, liver, pancreas, and anus.

The excretory system is responsible for removing waste products, including solid waste, from the body. The colon, which is part of the large intestine, is where water is absorbed from undigested food and the remaining waste is stored until it is eliminated from the body.

The circulatory system is responsible for transporting oxygen and nutrients to cells and removing waste products, but it is not directly involved in the storage or elimination of solid waste.

The respiratory system is responsible for gas exchange and the elimination of carbon dioxide, but it is also not directly involved in the elimination of solid waste. The muscular system is involved in the movement of the body, but it is not directly involved in the storage or elimination of solid waste either.

13) When mRNA is "processed", what are the pieces of mRNA that are cut out and stay in the nucleus?

Introns

Exons​

Answers

Answer:

Introns

Explanation:

The coding region of the gene is the part of the gene that is transcribed. However, not all of the gene makes the final mRNA. There are sequences called exons and introns in the coding region of the gene.

The pre-mRNA contains transcribed sequences of both the introns and exons. However, the introns are removed from the final mRNA by splicing. The final mRNA that is translated to the protein only contains exons. An illustration is attached to illustrate this.

Explanation:

Use Darwin’s finches as example they were separated and speciation occurred in the changed beaks

In which situation is speciation MOST likely to occur is few members of the population are isolated from the others.

What can cause speciation?

The speciation process usually occurs due to adverse conditions imposed by the environment. Briefly, two causes are attributed for the process to occur: Geographical Isolation: When lineages of a species separate from the rest of the species for environmental reasons.

In this case, a species no longer identifies with it and thus it isolates itself from its environment.

Which is more important: the brain or the heart? Explain your reasoning.

Answer:

Explanation:

the heart pumps blood through your system, keeping you alive. the brain only helps you think. and plus, so many people in this world are dumb so they already surviving without a brain so the obvious answer is heart

I would like to say the heart is more important than our brain but without our brain how do we function. We simply wouldn’t function our brain tells our heart to pump sends impulses throughout our body allowing us to move our bodies speak and talk it converts our vision so we see correctly. The brain just simply does too much to be more important than the heart but the heart is what also keeps us alive pumping oxygenated blood throughout the body so you could argue both sides.

Answer:

Explanation:

Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability
