B. Metaphase II
C. Mitosis
D. Prophase I
The correct answer is option D. Prophase I
The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.
Answer:
Nick observes thickening and discoloration of the nail of the index finger. Nick is most likely suffering from an onychomycosis infection.
Explanation:
Onychomycosis is a chronic and progressive infection of the nails caused by fungi. In most cases it is produced by dermatophytes, and less frequently by yeasts and molds. It is the most frequent nail disease.
Onychomycosis can affect the appearance, thickness and color abnormally, both in the nails of the hands and the feet, although the nail of the big toe is the most frequently affected.
Answer: 256.2 m/s (meters per second)
Explanation: Distance covered is 12450km and time used is 13.5hours. We first convert these values to standard units for distance (meters) and time (seconds).
12450 km = 12450 x 1000 m = 12,450,000 m
13.5hours = 13.5 x 60 x 60 = 48,600s
Average speed =
The average speed of the jet is 256.2m/s
How many times does the rrTt combination appear in this Punnett square?
Answer: The combination produced is RRtt.
The combination rrTt does not appear in this punnett square.
Explanation:
As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.
A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment. It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.
Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.
The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.
To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.
