Answer:

the gar population will increase, the diving duck will decrease slightly and the crab population will decrease

Explanation:

Since the alligator population will decrease, the gar population won't have anything to limit their population, so they will increase fast. The crab population will decrease fast as there are more gars to eat them. The duck population will decrease slightly as the gar is eating more crabs then the duck

Answer: Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Explanation:

Coal is produced from wood through decayed animals that burry down the earth and also start to deteriorate and behind millions of years they become coal.

Answer:

3. convection resulting from temperature and pressure differences above land and water

Explanation:

Due to the the difference between the ability of land and to water to absorb and radiate heat energy, the land gets heated up by the sun more quickly than water during the hot afternoons. As a result, the air above the land surface gets heated up more quickly than that above water. Warm air being less dense than cold air will rise above to atmosphere creating a low pressure area on land. On the other hand, air above water is not heated up as quickly, thus the dense cooler air over water will rush in and replace the warm air that has risen above the land surface.

At night, the land cools off more easily than water, hence the air above the land surface is cooler. On the other, water does not lose heat as quickly as the land, hence the air above the water surface is warmer than that over land. Warm air over the water surface will rise above, while colder air from land will replace it.

Answer:

10[tex]m/s^{2}[/tex]

Explanation:

Formula to find acceleration is :

Acceleration = [tex]\frac{ChangeInVelocity}{TIme}[/tex]  

                      OR

Acceleration = [tex]\frac{Final velocity-Initial velocity}{Time}[/tex]

= [tex]\frac{70 - 0}{7}[/tex]

= [tex]\frac{70}{7}[/tex]

= 10[tex]m/s^{2}[/tex]

Answer: could be Trifolium repens Aka the white clover

Explanation:

Answer: A

Explanation:

It can't be B or D because to get the polypeptide chain, we need the mNRA first to go through the ribosome. It's not C because after the mRNA is generated in the nucleus, it undergoes some modifications like splicing and the addition of the 5' cap and 3' tail.

The answer to the question is option A which is mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified.

In its most basic form, expressing a gene implies producing its matching protein, and this multi-step process comprises two primary phases. The information in DNA is converted to a messenger RNA (mRNA) molecule in the first phase, which is known as transcription.

During transcription, the DNA of a gene acts as a template for complementary base pairing, and an enzyme called RNA polymerase II catalyses the creation of a pre-mRNA molecule, which is subsequently processed to form mature mRNA. The mRNA that results is a single stranded copy of the gene that must then be translated into a protein molecule.

The genetic coding is used to "read" the mRNA, which connects the DNA sequence to the amino acid sequence in proteins, during translation, the second key step in gene expression.

Each codon in mRNA is made up of three nucleotides and represents a different amino acid.

As a result, The mRNA sequence serves as a template for constructing the chain of amino acids that comprise a protein in the correct order.

So we can conclude that first mRNA strand is formed then mRNA is processed, then polypeptide chain is formed and protein is modified.
