The diagram shows the motion of a group of water molecules over a heat source.

How do the molecules at point A compare to the molecules at point B?

They are farther apart.
They have increased in size.
They have lost energy.
They are moving slower.

During dehydration synthesis, water molecule gets removed. The correct option is a.

A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.

"Chemical processes known as dehydration reactions are those in which a water molecule is removed from the reactant molecule. Dehydration synthesis is the process of combining two compounds while removing water molecules.

These kinds of reactions can assemble and disassemble nucleic acids, proteins, and carbohydrates, however the monomers in each case vary.

Many polymers are made by dehydration processes as well. Another illustration is the transformation of alcohols into ethers.

Thus, the correct option is a.

Explanation:

Answer:

Answer:

The correct answer would be "contains coded information for the creation of proteins".

DNA or deoxyribonucleic acid is a polymer of nucleotides.

It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.

In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.

The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.

It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.

The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).

Explanation:

The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).

According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T)  and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.

The bases are Adenine, guanine, guanine, cytosine, thymine,  adenine the string of their base pair would be Thymine, cytosine, cytosine, guanine, adenine, thymine.

DNA stands for Deoxyribonucleic acid. It is made up of two complementary strands. There are four nitrogenous base present in the DNA strand. These are-

Adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair with bases on the complemenatry strand just according to the  Watson and Crick base pairing ( A=T, G ≡ C ). Uracil is another nitrogenous base. But it is present in RNA in place of Thymine.

Thus, bases found in the DNA are Adenine, thymine, guanine, cytosine.

Answer:

As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.

There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.

There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:

Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.

Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.

Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.

Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.

It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.

Answer:

Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.
