Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

<em>In any one species, the amount of adenine closely approximates that of thymine. </em>
<em>In any one species, the amount of guanine closely approximates that of cytosine. </em>
<em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA A T G C </u>

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

Write a short essay (not more than 5 sentence ) on how you think life began on earth

Snezhnost [94]

Answer:

The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.

A human liver cell is very different in structure and function from a nerve cell in the same person. This is best explained by t

Yuri [45]

<h2>Liver cell Vs Nerve cell</h2>

Explanation:

b. liver cells can reproduce while the nerve cells cannot.

Liver cells , the fundamental units of liver are called hepatocytes. Hepatocytes secrete bile that helps in digestion by emulsifying fats. Hepatocytes are capable of dividing and they can regenerate damaged parts of the liver.

In contrast,

Nerve cells, the fundamental unit of nervous system are neurons. Neurons are longest cell of the human body and they contain a cell body and a long axon. Neurons conduct nerve impulses. Neurons are incapable of dividing and hence once damaged neuron cannot be replaced.
