Answer:

The correct answer is option A. "Hormone receptors evolved later than many of the hormones with which they now interact".

Explanation:

It is false to affirm that hormone receptors evolved later than many of the hormones with which they now interact. There are multiple scientific studies that support the theory that  receptors and ligands evolve at the same time  in what is known as "synchronous birth". Receptor and ligand interactions are key components in the processes of living organisms, therefore, it they should evolve together in order to be functional.

From what you should now know about bacterial taxis and nodule formation, predict how a rhizobium would respond to a flavonoid.
andreev551 [17]

Answer;

-The bacterium would exhibit positive chemotaxis.

Explanation;

-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.

Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
myrzilka [38]

Answer:

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461

Explanation:

Given -

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Number of students with curly hair is 37

Thus frequency of genotype "CC"

= q^{2} = \frac{37}{117} \\= 0.3162

Thus, frequency of allele "q"

= \sqrt{0.3162} \\= 0.5623

As per Hardy Weinberg's first  equation-

p+q=1

Substituting the value of q, we get -

p+0.5623=1\\p= 0.4376

As per Hardy Weinberg's second equation -

p^2+q^2+2pq=1\\

Substituting the values of "p" and "q" we get -

0.4376^{2} + 0.3162+2pq = 1\\2pq = 0.2461\\

Hence,

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461
