__________ 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.

Answer:
A. sister chromatids separating
Answer:
will go for b. crossing over
Explanation:
"The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads."

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
