1. During which of these phases is DNA least condensed? a. Metaphase b. Anaphase c. G2 d. Prometaphase 2. Sunflowers have 34 chromosomes in diploid cells. How many chromosomes would be found in a haploid pollen grain? a. 17 b. 34 c. 51 d. 68 3. In horses, neural cells and liver cells have drastically different shapes and functions. Based on what we have learned this week (and last week), what most likely explains these different functions? a. Neural cells and liver cells have different amounts of DNA b. Neural cells and liver cells have different amounts of genes c. Neural cells and liver cells express different genes d Neural cells and liver cells have different numbers of chromosomes

Step 1
Step 2: Sunflowers have 34 chromosomes in diploid cells. How many chromosomes would be found in a haploid pollen grain? - A haploid cell has half the number of chromosomes as a diploid cell. Therefore, a haploid pollen grain from a sunflower would have 17 Show more…
