Answer:
when placed in hyper tonic solution , the cytoplasmic volume of elodea plant will be reduced, this is because, elodea is a water plant with high water potential; therefore,with cytoplasm of high water potential elodea will loose water from the cytoplasm to the external; hypertonic solution, of lower of potential by osmosis. This reduces the cytoplasmic volume.With time the protoplasm pulls away from the cell wall, and the whole elodea structure shrinks.
However,, when RBC is placed in hypotonic solution, of higher water potential than the RBC (which has lower water potential), the cytoplasmic volume increases as water moves into the cytoplasm by osmosis. The RBC swells and eventually busted. This is hemolysis.
Explanation:
Answer:
water is considered a renewable resource.
Answer:
0.2 (or 20%)
Explanation:
The allele frequency can be calculated by counting how many times an allele appears in a population and then by dividing this number by the total number of alleles of the gene. In this case,
- Genotype BB = 30 moths >> 60 copies of the B allele
- Genotype Bb= 12 grey moths >> 12 copies of the B allele and 12 copies of the b allele
- Genotype bb= 3 white moths >> 6 copies of the b allele
The total number of copies of the gene is:
Dominant (B) allele = 60 (BB genotype) + 12 (Bb genotype) = 72 B alleles
Recessive (b) allele = 12 (Bb genotype) + 6 (bb genotype) = 18 B alleles
Then, 72 + 18 = 90 alleles
Allele frequencies:
Dominant (B) allele = 72/90 = 0.8 (or 80 %)
Recessive (b) allele = 18/90 = 0.2 (or 20%)
