Answer:
1. 100,000,000 pb
2. 3.33%
3. 3.33%
4. 1.11%
Explanation:
1. You just need to multiply the number of genes to the average size: 10,000pb*10,000pb= 100,000,000 pb
2. If 3,000,000,000 equals 100%, we use the rule of three:
3,000,000,000 – 100%
100,000,000 – X
X= (100,000,000*100)/3,000,000,000 = 3.33%
3. It equals the proportion of genes in the total genome, and since a random mutation can occur in any part of the genome, the fraction of gene material equals the probability.
4. Assuming that only one of 3 mutations will result in a protein change, We could assume that is the third part of the probability that this mutations occur in a gene, so: 3.33%/3= 1.11%.
Strategic minerals are resources or elements that are important to everyday life because it can be a source of renewable energy and are used in manufacturing household items, equipment regarding national security, and agricultural production.
Africa is leading worldwide in terms of abundance of strategic minerals like diamond, platinum, chromium and many more. Other essential minerals such as gold, silver, copper and colored gemstones are critical minerals are imported from Afghanistan.
Answer:
the nucleotide sequence of mRNA is 3'UCA5'.
Explanation:
this is because the coding strand mRNA has base pairs opposite to the DNA template strand .sine in case of RNA URACIL is opposite to ADENINE and CYTOSINE IS opposite to GUANINE. nad ADENINE is opposite to THYAMINE. so the correct sequence is 3'UCA5'.
An accompanying diagram is need to answer this question. Mechanical or physical weathering involves the break up of rock into smaller pieces. Mechanical weathering does not change the chemical composition....it is just broken down into smaller pieces.
In frost wedging the constant freezing and thawing will break rocks into smaller pieces. This occurs in temperate mountainous regions.
Salt wedging occurs at coastal areas where ocean water deposits the salt in the rocks. Peeling is also known as exfoliation and this occurs in desert regions rocks constantly contract and expand as the temperature drastically changes.
Biological weathering is caused by plant roots or burrowing animals. Their actions cause rocks to be broken into smaller pieces.
The diagram that does not demonstrate any of these activities is not likely to be mechanical weathering.
StMary's a good day for me and you are the kids going ❤️❤️ a good time☺️☺️
