Answer:

The correct answer is - 6.5 to 7.5 pH.

Explanation:

The proper acidity or alaklinity or pH of an environment affect the growth of the microbes. The most suitable pH value for the most of the microbes are between 6.5 to 7 pH.

Most bacteria influences bacterial growth positively around neutral pHvale which is 6.5 to 7.5. However, some present in acidic nature called acidophiles as they can tolerate pH value of 1.

Thus, the correct answer is - 6.5 to 7.5 pH.

Which statements describe proteins? Select three options.
andre [41]

<u>Complete Question:</u>

Which statements describe proteins? Check all that apply.

A.) Proteins are created from the code in DNA.

B.) Proteins are synthesized in the nucleus of a cell.

C.) DNA and RNA are proteins.

D.) Amino acids are the building blocks of proteins.

E.) Proteins affect the structures and functions of living things.

F.) The shape and the function of a protein are not related.

<u>Correct Option:</u>

The statements which describe proteins are as follows:

A.) Proteins are created from the code in DNA.

D.) Amino acids are the building blocks of proteins.

E.) Proteins affect the structures and functions of living things.

<u>Explanation:</u>

Transcription is the method of RNA molecule creation from DNA. The translation is the mechanism by which the protein material is produced from the RNA molecule. Originally, protein forming data is contained in the DNA in the context of nucleotide code. The mechanism of translation happens in the cytoplasm and not at the nucleus.

DNA and RNA contain nucleotides and not proteins. Proteins are the alpha amino acid polymers, which serve as the building block of the protein. An individual's phenotype relies on the composition of the protein, and protein determines the composition and phenotypic expression in living organisms. 3D structure of proteins and their work are realized with one another.

In mammoths, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-woo
lisabon 2012 [21]

Answer:

Genotypic and Phenotypic ratios → 1:1:1:1

  • 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair, SsWw
  • 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair, Ssww
  • 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair, ssWw
  • 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair, ssww

Explanation:

<u>Available data</u>:

  • spotted skin (S) is dominant over non-spotted skin (s)
  • wooly hair (W) is dominant over non-wooly hair (w)
  • Cross: heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth.

Parentals) Ssww   x   ssWw

Gametes) Sw, Sw, sw, sw

                 sW, sW, sw, sw

Punnett square)     Sw            Sw           sw           sw

                  sW      SsWw      SsWw      ssWw     ssWw

                  sW      SsWw      SsWw      ssWw     ssWw

                  sw      Ssww       Ssww       ssww      ssww

                  sw      Ssww       Ssww       ssww      ssww

F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair

    4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair

    4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair

    4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.

Genotypic and Phenotypic ratios → 1:1:1:1
