lara31 [8.8K]

This happens because when leaf are submerged it is using light to continue process of photosynthesis, this process includes the release of oxygen that we see in bubble format .

<h3>Why the gases came out of the leaf when it was put into warm water?</h3>

When the leaf is put in warm water it is using light to continue the process of photosynthesis. Part of this process is to let oxygen out of the leaves. It is this oxygen that you are seeing as bubbles in the water.

<h3>Which part of the leaf the gas came from?</h3>

The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata.

If a light is traveling straight up out of the ocean, then moves out of the air it will become less refracted because it is moving to a far less-dense medium, meaning the image will not be distorted.

What differs among DNA structures of different species?
weqwewe [10]

Answer:

D) the arrangement of the nucleotides within genes

Explanation:

De-oxy ribo nucleic acid that is basically a polymer of nucleotides. Nucleotides are composed of three basic units: a de-oxyribose sugar unit, a phosphate group and nitrogenous bases that can be Adenine, Gunanine, Thymine and Cytosine.Adenine always pairs with Thymine and Guanine always pairs with Cytosine.

This is a universal composition of DNA in each and every living organism. The genes are a segment of DNA that contain specific sequence of nucleotides and encode for a specific trait of organism such as height, weight, eye color etc. The sequence of nucleotides expresses the trait in the form of protein product during the process of Translation. The products of translation are amino acids and every amino acids encode for a specific protein  in almost  all living organisms.

So, what differs in the specie is the sequence of nucleotides in genes. Infact this is the nucleotide sequence which brings evolution in organism and organisms evolve to form new specie with the passage of time. One major cause of change in nucleotide sequence is mutations due to which the organisms change with time.

Suppose the sequence of nucleotide of specific gene in organism A is

AAGGGGAAATTT

However in other specie organism B of same specie is:

TAGGGGAAATTT

This means only mutation of one base changed the gene in organism B and also its product called protein.

Hope it help!
