The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominan

t, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38

Answer:

The correct answer is - 1133.

Explanation:

According to H-W equilibrium;

p2 +2pq + q2 = 1 ........... eq.1   and

(p+q)2 = 1 ..............eq.2

Here q = frequency of the recessive allele,

and p = frequency of the dominant allele in the population

The genotype of p2 + 2pq shows the dominant(taster) phenotype.

The genotype of q2 shows the recessive(non-taster) phenotype.

q^2 = (2400 - 1482)/2400

= 0.3825  

= 0.618

using eq. 2 we get p= 1-q

=0.382

2pq = No. of heterozygotes/2400

No. of heterozygotes = 1133.1648

nydimaria [60]

The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.

The rate of water loss from the leaves of a potted plant can be measured by determining the mass of the plant at one-hour interv
marusya05 [52]

Answer:

A potometer measures water loss from leaves. A bubble potometer measures the rate of water loss from a plant by transpiration. A weight photometer measures the amount of water lost by a plant through transpiration. The washing line method is used to prove that most water loss occurs from the lower surface of the leaf.

potometer' (from Greek ποτό = drunken, and μέτρο = measure), sometimes known as transpirometer, is a device used for measuring the rate of water uptake of a leafy shoot which is almost equal to the water lost through transpiration. The causes of water uptake are photosynthesis and transpiration

Suppose you ate an entire bag of potato chips and drank a 16-ounce cola while you studies for an exam. Together these items cont
Anastaziya [24]

Answer:

Total of 1164.187 kilo-calories are consumed.

Explanation:

In order to determine the total calories present in any food item, the calories contribution of each of its constituents must be know.

Here,

Calories in one gram of carbohydrate = 4 kilocalories

Calories in one gram of protein = 4 kilocalories

Calories in one gram of fat  = 9 kilocalories

As per the details provided on Coca-Cola website, calories in 16-ounce cola = 187 calories = 0.187 kilocalories

Thus, total calorie in  an entire bag of potato chips and  16-ounce cola

(144 * 4) + ( 12 * 4) + (60 * 9)  + 0.187\\= 576 + 48 + 540 + 0.187\\= 1164.187

Total of 1164.187 kilo-calories are consumed.
