Answer: The contaminants would move quickly to the groundwater in channels.

Karst aquifer are the source of ground water. These are based on special type of fractured rock (limestone, dolomite or magnesite) in which when water comes from any natural source like rain dissolves the soft rocks, thereby the size of the fractures increase which may act as a channel to deposit water in the under surface of rocks. The groundwater in the Karst aquifer is vulnerable to pollution because of the rocks gets solubilize by the affect of water from external source. The contaminant from these rocks can be quickly transferred to the groundwater.

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:

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

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

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.

How do mutations work in dna sequences? I'm so lost

liraira [26]

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Describe the structure and the function of the stomach. Be sure to include cells and tissues relating to this organ.

Vikentia [17]

Connective tissues support the tissues of the mucosa and connect it to the muscularis layer.

The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.

<h3>What is the function of the stomach?</h3>

The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach.

The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

Thus, this could be the answer.
