Receptor cells for our sense of ________ reproduce themselves every week or two. vision hearing taste equilibrium
patriot [66]
Taste

Taste buds or taste receptor cells in the tongue allow a person to taste the different flavors of the food he or she eats. An average person has around 10,000 of these cells, which gets replaced every week or two. As a person gets older, cell replacement is much slower and some of these cells do not get replaced anymore. An older person may then have only about 5,000 working taste buds.

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu
uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

  • Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
  • Forward and reverse primers (to customize the start of the enzyme reaction)
  • DNA polymerase (Enzyme required for replication of desired DNA region.)
  • DNA Template (the DNA to be copied)
  • PCR-grade water
  • Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).

In a tropical forest there is a species of bird that has a variable tail length. Long is incompletely dominant over short. In on
Temka [501]

Answer:

Frequency of long trait allele = 0.55

Frequency of long trait allele = 0.45

Explanation:

Given -

Total Number of birds  - 2000

Let us assume the given population is in Hardy Weinberg's equation -

Frequency of individuals with birds having long tails is depicted by p^2

Frequency of individuals with birds having short tails is depicted by q^2

Frequency of individuals with birds having medium tails is depicted by 2pq

Frequency of individuals with birds having long tails

\frac{614}{2000} * 100\\= 30.7

p^2 = .307\\p = 0.554

Frequency of individuals with birds having short tails

\frac{413}{2000} *100\\20.65

q^ 2 = 0.2065\\q = 0.4544

Rounding off the values of p and q we get

Frequency of long trait allele = 0.55

Frequency of long trait allele = 0.45

Sum of both  p and q should be unity

0.55+ 0.45 = 1
