<h2>Correct answer is option"e"</h2>
Explanation:
- Headache is a migraine which influences one portion of the head which endures from 2-72 hours.
- It influences a larger number of young male than young females before puberty and more young females then young male after puberty. The normal side effects incorporate retching, sickness, affect ability to light, stable and smell.
- Prevalence is characterized as the quantity of influenced people present in a populaces at a particular time partitioned by the quantity of people in the populace around then.
- Hence, the correct answer is option "e"
Answer:
0%
Explanation:
The cross of a pea plant with round seeds (RR) with another pea plant with wrinkled seeds (rr) is shown as under :
P RR x rr
F1 Rr Rr Rr Rr
It is clear from the cross above, all the 4 probable progenies in filial 1 (F1) generation will be heterozygous with Rr genotype. Not even a single progeny will have homozygous recessive genotype which is responsible for producing wrinkled seeds. Also, even though the genotype of the progenies will be Rr not RR yet phenotypically they all will have round seeds i.e. they will show dominant trait. The reason behind it is that one of the alleles R which is responsible for dominant trait will mask the expression of recessive allele r. So, wrinkled phenotype which is a recessive trait will not be observed in any of the progenies.
Answer:
D. LINE-promoted transposition.
Explanation:
Pseudogenes are traditionally defined as sequences that closely resemble known genes but do not produce a functional protein, which in many cases were actually genes, or copies of genes, degenerated by mutational processes that alter the reading frame of coding regions (ie that encode the amino acid sequence) or that interfered with the promoter elements that controlled their expression.
Pseudogenes originate by the same mechanisms as protein coding genes, followed by the subsequent accumulation of disabling mutations (e.g., insertions, nucleotide deletions, and / or substitutions) that disrupt the reading sequence in the coding regions, or lead to the insertion of a premature termination codon or the aforementioned reading frame change. However, it is believed that the transposition promoted by LINE is the main transposition responsible for the appearance of pseudogenes.

Answer: karyotype
Explanation: if you suspect trisomy, you need to count chromosomes!
