6 0

Answer:

Presence of acidic oxides and other chemicals in air can change the PH value of the Rain.

Explanation:

Generally, PH value of rain remains 5.0. But when the air composition changes due to sulfur dioxide or nitrogen oxides released from automobiles and coal based power plants, the combination of these with rain water makes rainy water more acidic. This results in change of PH value of Rain.

Answer:

mRNA destroyer concentration has a greater influence because it is destroying mRNA before  proteins can even be produced.

Explanation:

<em>Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.</em>

Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.

How many dna molecules are present in your diploid cells
Tcecarenko [31]

Answer:

92 molecules

Explanation:

DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.

Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).

Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
