Answer:
1. How did the tidal wave affect the predicted frequencies of the alleles in the population?
No changes
2. What is the frequency of the recessive allele?
q= 0.6
Explanation:
If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.
If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:
q^2 = 36/100
q= √36/100= 6/10= 0.6
Answer:
The cell membrane separates the external and internal environment of the cell. The cell membrane is composed of bilayer lipids, proteins and small amount of carbohydrates.
The lipid part is soluble in hydrophobic environment or with the hydrophobic part of other phospholipids because like molecules dissolve in like molecules. The hydrophobic part is non polar and hydrophilic parts is able to dissolve in polar area due to the interaction of same molecules with each other.
Answer:
One easy way to measure the "size" of a ball is how far it is from side to side. Your tennis ball example is a good one: a typical tennis ball is about 2.5 inches form side to side.
