During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!
El Niño affects global weather because precipitation increases in South and Central America and also decreases in Africa, Asia, and Australia (Option C).
<h3>What is 'El Niño'?</h3>
The 'El Niño' is a climatic phenomenon associated with the formation of violent storms that cause flooded areas in America.
It has been suggested that 'El Niño' may be associated with global warming and increased its activity in the last years.
In conclusion, El Niño increases precipitation in South and Central America and decreases it in Africa, Asia, and Australia (Option C).

Color blindness is a recessive x-linked trait in humans. In a family where the mother is color-blind, and the father is normal, the probability of their having a color-blind son is 100%.
Color blindness is a recessive x chromosome liked recessive disease which is more prone in males than in females. As the mother is color-blind she has both the alleles of colorblindness while the father is normal with both x chromosome and y chromosome normal.
So if the parents have a boy, he will always receive an x chromosome with colorblindness gene from the mother and a normal y chromosome from the father always. Thus, the probability of having a colorblind boy will be 100%.

The answer would be you bounce a basketball
The correct answer is B. 1 red; 2 pink; 1 white
Explanation:
In genetics, the combination of alleles (genotype) determines the phenotype or physical features; for example, in this case, the color of the flowers in the snapdragon plants can be determined by the combination of dominant alleles (R) and recessive (r) alleles. Additionally, in the case presented, a dominant allele combined with a recessive allele (Rr) leads to pink snapdragon plants, while two dominant alleles (RR) lead to red snapdragon plants, and two recessive alleles (rr) lead to white snapdragon plants.
According to this, the generation F2 shown in the chart produced 1 red plant because there is only one plant with RR genotype; 2 pink plants because there are two plants with Rr genotype; and finally one white plant because the last plant has an rr genotype.
