Nitrites are often added to meat products as preservatives. in a study of the effect of these chemicals on bacteria, the rate of
tatyana61 [14]
Nitrites are 307880 115 and control is 30 8112 1250
Let X be nitrate group and let Y  be a control group.
If ∪X-∪Y∠0 then we can say that nitrates decrease the number of amino acids which is taken.
Hypothesis test.
H0:∪X-∪Y=0Vs. Where H1:∪X-∪Y∠0.
Sample for X = 7880 and Y = 8112 and Sx∧2=variance sample for X = 1115∧2 = 1243225 and Sy∧2 = variancesample for Y= 1250∧2 = 1562500. The size of the sample = 30 for both cases.
Test statistics is Z =((7880-8112)-0)/squareroot (1243225/30+1562500/30) = 0.758623)
Value of P = P(Z∠z)
=P(Z∠-0.758623).
Since P-value is greater than the importance of 0.02, we can not reject the null hypothesis. The conclusion is that ∪x-∪y =0 a good example is nitrates does not decrease the number of amino acid which is taken.

How does gene therapy work to reverse the causes of cancer we learned about today?
tatiyna

Answer:

Explanation:

In gene transfer, researchers introduce a foreign gene directly into cancer cells or into surrounding tissue. The goal is that the newly inserted gene will cause the cancer cells to die or prevent cancer cells and surrounding tissue from funneling blood to tumors, depriving them of nutrients they need for survival.

a pollutant released on one continent is found concentrated in the tissues of organisms on another continent. Is this likely an
Neporo4naja [7]

Answer:

It is most likely an air and water pollutant.

Explanation:

The continents are separated with water and air. Therefore, if a pollutant is released from one continent, it could have transported to the other continent via water and air. Although the effect of air is less due to dispersing of air masses, it still have a chance to transport the pollutant at far distance. This phenomenon can also be related with the <u>transboundary pollution</u> where a pollutant travels to another place. For example, many persistent organic pollutants have beend detected in the bodies of polar bears living in arctic.

Master genes that affect development tend to be highly ____; therefore, similarities in patterns of embryonic development reflec
Yanka [14]

Answer:

Master genes tend to be conserved.

Explanation:

Master genes, which are the genes in the DNA that control major development processes such as the development of the skeleton, the organs etc and the production of the necessary proteins.

Since they take on such an important role, they don't really change much. Master genes that affect development tend to be highly conserved so embryonic development can show similar patterns.

I hope this answer helps.
