Explanation:
A directional flow of electric charge
Answers
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart. Actually, electrons would go in the reverse direction across the cables.
What is electric current ?A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
The cell phone, trains, ships, refrigerator, and the motors in appliances like food processors all run on electricity. To be useful, electric energy must be converted into other forms of energy like heat, light, or mechanical.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart.
Thus, a positive charge would go in the same direction as an electric current.

Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)

Answer:
Explanation:
Okay, so the female's eyes will be Xx because she carries it and I am not sure if the male is a carrier as well or not so if he is it will be Xx on the top and Xx on the side of the male is not then it will be XX and Xx and it does not matter which is on top which is on the bottom. If the male is a carrier then the outcomes will be XX, Xx, Xx, xx so they will have a 1:4 chance of getting white eyes if the male is NOT a carrier then it will be XX+Xx = XX, XX, Xx, Xx with no chances of having white eyes
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
Answers
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

Answers
Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
The correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.
What is gene expression?It is the process by which cells produce protein from DNA molecules. DNA produces RNA which contains codes to produce amino acids.
The mRNA enters the ribosome which produced protein using the codons of mRNA.
Retroviruses have special machinery to produce the DNA from mRNA.
Therefore, the correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.
