8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the allele B leads to blue beetles. Heterozygous beetles are red and blue spotted. A heterozygous beetle mates with a red beetle. What is are the genotypic and phenotypic frequencies of their offspring? Please show all of your work. (2)
Answer:
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
Explanation:
Given that:
The allele → R = Red beetles
The allele → B = Blue beetles
Since the gene color shows a codominant allele
The Red Beetle = RR
The blue beetles will be = BB
The heterozygous beetle will be = RB
∴
The punnet square showing the crossing of RB × RR is:
R B
R RR RB
R RR RB
The result shows that we have two red beetles and two heterozygous beetles.
Hence;
The genotypic frequency = 1:1
The phenotypic frequency = 1:1

__________ give you energy and help you feel satisfied after eating.
Animals, including humans, derive chemical energy from their food to support their metabolism, including their muscular activity.
What is the source of energy from food?The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
Cells release energy from nutrients through the process of respiration. The majority of the time, glucose has already been produced from the food.
Because they work quickly and provide energy as soon as they are taken, carbohydrates—which have 4 kcal per gram—are the foods that are used as an energy source the most frequently.
Therefore, food give you energy and help you feel satisfied after eating.

How can you identify whether
plant is monocot or dicot without uprooting the plant?
Answer:

oxygen is very electronegative and therefore is a strong reducing agent
The oxygen atoms undergo reduction, formally gaining electrons, while the carbon atoms undergo oxidation, losing electrons. Thus oxygen is the oxidizing agent and carbon is the reducing agent in this reaction.
How does oxygen enter the urchins system?
Answer:
Enters through the gills and tubed feet.
Explanation:
The oxygen obtained by a Purple Sea Urchin is dissolved in water. Oxygen enters through the gills and tubed feet. When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through the body (through the canals).
Any Questions?
Oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.
What is the water vascular system?The water vascular system is seen in the phylum of the echinodermata, which is essentially a network of canals and tube feet that run throughout the urchin's body, and the tube feet are helpful for the attachment to the surface and for the respiration. When the tube feet are extended, oxygen from the water diffuses across the walls of the tube feet and into the urchin's body, while carbon dioxide is released into the water.
Hence, oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.

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