4 0

Answer:

Z

Explanation:

The first stage of cellular respiration is called GLYCOLYSIS, where glucose is broken down into pyruvate. Because glycolysis occurs irrespective of whether there is oxygen or not, it occurs in all organisms. Hence, glycolysis occurs in the CYTOPLASM of their cell.

In this question, a diagram was given as an attachment. In the diagram, letters W, X, Y amd Z are used to represent organelles in the cell. Letter Z represents the cytoplasm, hence, the first stage of cellular respiration takes place in Z.

Answer:

RFLP analysis.

Explanation:

RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.

The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.

Thus, the correct answer is option (1).

A mutation occurs in an original DNA template that changes the DNA, changes the RNA, but does not change the protein sequence. W
jonny [76]

Answer:

<h2>The changes that do not affect the function of a protein are called silent mutations.</h2>

Explanation:

As given here as a mutation occurs in an original DNA template that changes the DNA, by transcription this mutation passes into RNA and changes the RNA, but it does not change the protein sequence, it means that this mutation could be silent mutation.

Silent mutation is the mutation which cause the change of a base in that, after the mutation the codon codes for the same amino acid, or the amino acid which do no cause any change in the protein, hence these changes do not affect the function of a protein.

"Superior vena cava carries completely digested substances"
Savatey [412]

Answer:

Yes.

Explanation:

As a blood vessel, Superior vena cava carries completely digested substances that is present in the blood from upper part of the body to the heart. Blood is a fluid that transport digested food from small intestine to other parts of the human body. It also carries oxygen from the lungs to the cells and also carries carbondioxide from the cells to lungs so we can say that Superior vena cava carries completely digested materials.
