Answer:
           
                  The correct option is b (false). 

Explanation:
     
                    As is is cleared from the figure that when lactose is absent, the lac repressor binds tightly to the operator. It gets in RNA polymerase's way and prevent transcription.

Lac repressor does inhibit expression of the lac operon when there is no lactose present (because it's a waste to make these proteins when there's no lactose around), however, the statement above is false because the lac repressor binds to the OPERATOR site, not the promoter.

svp [43]

Answer:

the answer is Newton's third and Second law

Explanation:

Newton's second law tells us that the force that is generated on a body is proportional to the acceleration it acquires.

F= M*A

at lower mass greater acceleration

Newton's third law explains that for each force that acts on a body, it performs a force of equal intensity and direction but in the opposite direction to the body than gender.

I hope it's help you

Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the frequencies of the genotypes.

<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>
