Answer:

The start of the period was marked by the major Triassic–Jurassic extinction event. Two other extinction events occurred during the period: the Pliensbachian-Toarcian extinction in the Early Jurassic, and the Tithonian event at the end; neither event ranks among the "Big Five" mass extinctions.

if a rabbit consumes 500 calories of plant material, how much of that would be passed on to a hawk in the following food chain?
slamgirl [31]
10% of energy is lost (to heat), for each level of the food chain. So the rabbit would have 500, the snake would have 50 and the hawk would have 5.

Which of the following scenarios would be most likely to cause a weak point in the aorta to rupture, and why? (2 points)
REY [17]
<span>I believe the answer is,

High systolic, because when the heart pumps, the pressure inside the aorta would be greatest, causing the weak spot to rupture outward.

This indicates high blood pressure that causes rupture of the aorta or aorta dissection.</span>

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

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).

Based on the DNA strand below, and assuming the promoter for this gene is located to the le\, which protein sequence below does
Art [367]
<h2>Protein sequence</h2>

Explanation:

  • The given sequence is of coding strand(5'-3' direction)

5’-ATGTTGAAAATGCCGTAGAGGC-3’  

  • Protein is made up of mRNA and mRNA has the same sequence as coding strand(only T is replaced by U) so the sequence of mRNA will be:

5’-AUGUUGAAAAUGCCGUAGAGGC-3’

According to the genetic code,3 bases code for one nucleotide and further nucleotide codes for amino acid,amino acids forms the base for protein

  • AUG codes for Methionine(Met)
  • UUG codes for Leucine(Leu)
  • AAA codes for Lysine(Lys)
  • AUG codes for Methionine(Met)
  • CCG codes for Proline(Pro)
  • UAG codes for stop codon(Stop)

Once the stop codon comes protein synthesis will be stopped,so the final protein sequence will be:

Met-Leu-Lys-Met-Pro-Stop
