Answer: The probability of having an offspring that is dwarf in size is zero.

Explanation: Since tall phenotype is dominant to dwarf phenotype, let T represent allele for tall and t represent allele for dwarf. A heterozygous pea plant will have Tt genotype while a homozygous tall pea plant will have a TT genotype. A cross between them will produce two homozygous tall pea plants (TT) and two heterozygous tall pea plant (Tt). They will not have any offspring having a dwarf size. Therefore, the probability of having a dwarf offspring is zero.

<h3>Question from alternative source</h3>

Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?

  • silent
  • missense
  • nonsense
  • deletion

Answer:

Nonsense

Explanation:

Nonsense mutations describe mutations that produce a premature stop codon. The stop codons are UAG, UAA, and UGA. A way in which this could arise is, for example, if there was a substution of a nucleotide in the mRNA codon UAC (which codes for the amino acid Tyrosine) to the nucleotide UAG (which codes for a stop codon).

The translation machinery would reach this codon, which signals that translation should be terminated. This would mean that the mRNA would be released, and a truncated (shortened) version of the amino acid would be produced. This is likely to be non-functional, and may even be marked for destruction by the cell.

What hormone is responsible for stimulating the breakdown of liver glycogen and its release as glucose?
Lostsunrise [7]
The hormones that stimulate the breakdown of liver glycogen are epinephrine and glucagon. Epinephrine is the one that triggers the glycogen breakdown inside the muscle and also inside the liver. However, the liver is the one that is more active or responsive to the hormone called glucagon than the muscles. A glucagon is a hormone which is a polypeptide hidden by the cells of our pancreas called α cells whenever our blood-sugar is low. This hormone indicates the state of starving.

The correct answer is the extensor digitorum longus and fibularis tertius.
The pretibial muscles include the anterior tibialis, extensor digitorum longus, extensor hallucis longus, and peroneus tertius. As a group they are active during the swing phase and the heel-strike to foot-flat phase of gait. Fibularis is often considered as part of the extensor digitorum longus muscle.
