mihalych1998 [28]

Answer:

c) There will be a net movement of salt from side B to side A

Explanation:

According to the given information, the solution at side A is hypotonic to the solution at side B. The separating membrane is permeable to salt and would allow the movement of salt from the hypertonic side B to the hypotonic side A. Transport of substances down their concentration gradient is a passive movement and occurs from the region of higher concentration of the substance to that of its lower concentration.

natulia [17]

Options for the question are not given. They are as follows:

a. arg or lys

b. ala

c. thr

d. leu or ser

e. Only termination codons

Answer:

d. leu or ser

Explanation:

Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.

If first position is changed in each codon:

CCT = TCT (UCU)

CCC = TCC (UCC)

CCA = TCA (UCA)

CCG = TCG (UCG)

These codons produce Serine amino acid.

If second position is changed in each codon:

CCT = CTT (CUU)

CCC = CTC (CUC)

CCA = CTA (CUA)

CCG = CTG (CUG)

These codons produce Leucine amino acid.

Hence, out of the given options, option d. leu or ser is correct.

Which of the following statements is correct?
Keith_Richards [23]

Answer:

The statement that is correct is that all cells have the same genes, but different genes are active in different cells.

Explanation:

Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.

Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.

All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.

The other choices are wrong because:

  • <em>The eyes look different from the liver, because they have the same genes, but only some are expressed. </em>
  • <em>Differentiated cells and tissues do not lose their genes. </em>
  • <em>All cells have DNA.</em>
