The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.
<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.
Answer:
Bb, Db
, Bd and Dd
Explanation:
When a cross between two parents (having certain trait) is carried out , they share their alleles with each other to produce offspring with new traits. These offspring have gentically different allele combination as compared to their parents. A genetic cross can be represented by a punnet square (as given below)
The cross between two parents with genotype "BD" and "bd" will result into the following offspring -
B D
b Bb Db
d Bd Dd
Answer:
The answer is "Building artificial reefs and limiting fishing activity".
Explanation:
A variety of different methods could be used to construct an artificial island, which is most habitats are built to create a coral through using raw parts, and farming is the farming company, both "the creation of artificial reefs and restriction of fisheries" the activities are used to control environmental ecosystems throughout the region.
Can I see the picture please?
Just by reading the answers it seems like the correct one would be A, but i would like to double check.
