Identify the factors that made early Earth a hot planet.

What is the world’s largest carbon sink?

vladimir1956 [14]

A. The oceans.

That is because oceans absorb more than a quarter of the carbon dioxide that humans produce.

Hope that helped.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp

OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

<em>The DNA sequences may vary but the amino acid sequences are identical. </em>
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

In C3 plants the conservation of water promotes _____.

bija089 [108]

Answer:

The correct answer is d. photorespiration

Explanation:

In the C3 plant, the Rubisco enzyme is important that fix CO2 into organic molecule by binding with CO2. Rubisco can also bind to oxygen when the oxygen concentration increases in cells which leads to the loss of fixed CO2 and waste of energy which is called photorespiration.

So when stomata are open CO2 comes in and O2 goes out of the cell which maintains the high CO2 concentration in the cell but during hot days C3 plants close stomata to prevent water loss.

So closing of stomata decrease the intake of CO2 and increase the oxygen concentration inside the cell. So in increased temperature and high oxygen concentration, the rubisco enzymes bind to O2 and promote photorespiration.

Why is variation In a population beneficial

Aneli [31]

Some of the organisms might have different traits that allow them to survive better than others within the population. That way the population has a greater chance of surviving.
