Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles
FrozenT [24]

Answer:

The correct answer is - 4.34 days.

Explanation:

Given:

Distance from the sun to earth = 150 million kilometer

= 1500,00,000 km

The solar "wind" travels = 400 km/sec

= 400*60*60 km/ hour

= 1440000 km/hour

Then time = distance/speed

time = 1500,00,000 km/1440000 km/hour

time = 104.166666667 hours

time = 104.166666667/24

=  4.34 days.

Generally speaking, which of the following mutations.....? would most severely affect the protein coded for by a gene? -a base s
Svet_ta [14]
The answer is <span>a frameshift deletion at the beginning of the gene.

The frameshift deletion means that due to the deletion, the reading frame will be changed. Because of this, changed mRNA will be synthesized and translated into altered protein. It is known that codon is a triplet (a set of three nucleotides), that code for certain amino acid. The earlier in the sequence the deletion occurs, the protein will be more severely affected.
For example, if codons on RNA are THE BIG BAD DOG and the frameshift deletion happens on the first triplet (earlier in the sequence), the changed sequence will be  TEB IGB ADD OG. If </span>the frameshift deletion happens on the third triplet (later in the sequence), <span>the changed sequence will be THE BIG ADD OG.</span> This way, if the<span> frameshift deletion occurs at the beginning of the gene,</span> the more codons will be changed and in turn, they will code different amino acids.
