B) thymus
C) Peyer's patch
D) appendix
</span>
The correct answer is "tonsil". Tonsils are lymphoid tissue that is found in the oral mucosa. The tonsils are arranged in a ring-like fashion called the Waldeyer's ring. This ring comprises of two tubal tonsils, two palatine tonsils, one adenoid tonsil, and one lingual tonsils. In cases of infection involving the oral mucosa and the pharynx, the tonsils become inflamed as well and the condition is called acute tonsillopharyngitis.

Which of the following is a true statement about sexual vs. asexual reproduction? A. Asexual reproduction, but not sexual reprod

Afina-wow [57]

The correct answer is: B. In sexual reproduction, individuals transmit half of their nuclear genes to each of their offspring.

The main difference between sexual and asexual reproduction is that in sexual reproduction genetic material from two parents is combined, while in asexual reproduction produced offspring is genetically identical to the one parent. So, advantage of sexual reproduction is that produced unique organisms contribute to genetic diversity (variation is formed). But, comparing to asexual reproduction, sexual reproduction requires more energy and lasts longer.

Asexual reproduction is found in lower organisms and can be in different forms: budding, vegetative reproduction, fragmentation, spore formation.

Jill is heterozygous for gene A and is going to have a child with Jack, who is homozygous recessive for gene A. Which of the fol

Igoryamba

Answer:

D. Aa

Explanation:

Given:

Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa

Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa

Now if both cross and fertilization occurs, we have:

A a

a Aa aa

The offsprings are (Aa, Aa, aa, aa)

Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.

Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
