Matthew is paralyzed. it is likely his _____ transmission is blocked

Answers

Answer 1
Answer: Matthew is paralyzed. It is likely his ACh transmission is blocked. Acetylcholine is the neurotransmitter used at the neuromuscular junction—in other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles.

If you've been sitting in the hot Sun and start to sweat, your body responds from a _____. positive or negative feed back?

Answers

If you've been sitting in the hot sun and start to sweat, your body responds from a negative feedback.
The body responds from a negative feedback. Homeostasis is carried out in the human body under the principal of negative feedback, where changes are made in order to counteract the effect of a stimulus. For example, the stimulus is the sun and its effect is your body heating up. Therefore, by sweating, the body tries to reduce its temperature.

The ________________ in males and the _____________________ in females are permanently blocked when an individual undergoes a sterilization procedure.a. testes; ovaries

b. testes; fallopian tubes

c. vas deferens; ovaries

d. vas deferens; fallopian tubes

Answers

Answer:

The ________________ in males and the _____________________ in females are permanently blocked when an individual undergoes a sterilization procedure.

a. testes; ovaries

b. testes; fallopian tubes

c. vas deferens; ovaries

d. vas deferens; fallopian tubes

Explanation:

I believe the answer would be B. This would be because the Fallopian tubes I think are tied which then would help so the sperm cannot go up to the ovaries. We know that it is A or B because the first answer being tested is correct.

Three genes in fruit flies affect a particular trait, and one dominant allele of each gene is necessary to get a wild-type phenotype. a. What phenotypic ratios would you predict among the progeny if you crossed triply heterozygous flies? b. You cross a particular wild-type male in succession with three tester strains. In the cross with one tester strain (AA bb cc), only 1/4 of the progeny are wild type. In the crosses involving the other two tester strains (aa BB cc and aa bb CO, half of the progeny are wild type. What is the genotype of the wild-type male?

Answers

a. When crossing triply heterozygous flies (Aa Bb Cc), where each gene has one dominant allele and one recessive allele, the phenotypic ratios among the progeny would be 1:1. b. The genotype of the wild-type male can be deduced based on the phenotypic ratios observed in the crosses with the tester strains.

a. If you crossed triply heterozygous flies (Aa Bb Cc), where each gene has one dominant allele and one recessive allele, you can use the product rule to predict the phenotypic ratios among the progeny.

For each gene, the possible gametes are A and a, B and b, C and c. When you cross the triply heterozygous flies, you can determine the possible genotypes of the offspring:

Genotypes:

AA BB CC (wild type)

AA BB Cc (wild type)

AA Bb CC (wild type)

AA Bb Cc (wild type)

Aa BB CC (wild type)

Aa BB Cc (wild type)

Aa Bb CC (wild type)

Aa Bb Cc (wild type)

The phenotypic ratios can be determined by counting the number of wild-type (dominant phenotype) offspring and dividing it by the total number of offspring:

Wild-type progeny (AA BB CC, AA BB Cc, AA Bb CC, AA Bb Cc, Aa BB CC, Aa BB Cc, Aa Bb CC, Aa Bb Cc) = 8

Total number of progeny = 8 (since each possible genotype occurs once)

Phenotypic ratio: 8 wild-type : 8 total = 1:1

b. To determine the genotype of the wild-type male, we can deduce it based on the phenotypic ratios observed in the crosses with the tester strains.

In the cross with the tester strain AA bb cc, only 1/4 of the progeny are wild type. This means that the male being tested (wild-type male) must be heterozygous for the B and C genes (Aa Bb Cc) since the wild-type phenotype requires one dominant allele for each of the three genes.

In the crosses involving the other two tester strains (aa BB cc and aa bb CO), half of the progeny are wild type. This indicates that the wild-type male is homozygous for the A gene (AA Bb Cc) since the wild-type phenotype requires two dominant alleles for the A gene.

So, the genotype of the wild-type male is Aa BB Cc.
