Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.
Answer:
For the benefits we have had improvements in communication and transportation which has caused an increase in economic growth.
For the disadvantages this causes (urbanization) will allows people to live in urban areas.
Explanation:
Answer: Option D) 1:4
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.
Then, 10% + 10% + C + G = 100%
20% + C + G = 100%
C + G = 100% - 20% = 80%
Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%
Ratio Adenine to Guanine is 10% to 40%
or 1:4 in simplest form
Answer and Explanation:
Mitosis is the type of division that occurs in the general body cells resulting in growth while meiosis is the process that occurs during the formation of sex cells. Mitosis results in two daughter that are identical to one another and to the parent cell. In meisosis there is crossing over during prophase I.
