Answer:Yes, there is plenty of evidence, maybe to much. Many people throughout the article state many different reasons why red leaves protect the trees. (Maybe you should consider removing some information because it is a little long.)
Explanation: You should remove some of the information because this article
(assuming that you wrote this), is a bit wordy.
Answer:
e) the number of pairs of homologous chromosomes in a gamete.
Explanation:
A diploid cell is defined as the the cell containing two complete set of homologous chromosomes in a gamete.
In humans or other diploid sexually reproducing organism, sperm get fertilised with egg and produces a gamete with two haploid sets of chromosomes form a complete diploid set.A human diploid cell has 46 chromosomes in 23 pairs.
Hence, the correct option is e)
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.
Since this is a relatively short string of DNA, we can count the number of mutations between the two strings. Firstly, Species A has thymine as the 2nd nucleotide, while Species B has adenine.2. Second, the 7th nucleotide of A has cytosine while B has thymine. Finally, the 16th nucleotide (3rd from the last) of A has adenine while B has thymine.
Since there are 3 point mutations, we multiply this by the frequency of 10 million years per mutation to get a time of 30 million years.
