A woman with normal color vision has a colorblind daughter. what are the genotypes and phenotypes of both parents
vovikov84 [41]
 The only possibility of the daughter being colour blind is where both parents have a recessive gene for colour blindness with the father being colour blind as well. so assuming the recessive allele is Xc, then the genotype of the mother is XCXc, where she has a normal colour vision and the father's genotype is XcY, where he is colour blind.

Which of these statements is true about adaptive evolution? The ability to learn plays a key role in the process of adaptive evo
pentagon [3]
<span>The correct answer is "Sudden changes in the somatic cells of organisms play a key role in the process of adaptive evolution". Adaption in evolution is caused by sudden gene mutations that affect an organism's offspring and give it - potentially - a better chance of survival. For example, a giraffe who passed on a mutated gene for a slightly longer neck to its offspring gave its offspring a better chance of reaching untouched food, and thus a survival advantage.</span>

Now we need to prepare a buffer that has a pH of 7.4. We need this specific pH to
Anestetic [448]

Answer:

b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.

Explanation:

Hello,

In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.

Best regards.
