<span>D is the correct answer. In the F2 generation, 1 in 4 plants have two alleles for the dominant trait, 2 in 4 have one dominant and one recessive alleles and 1 in 4 has two alleles for the recessive trait.</span>
The right answer is: neutral mutation.
Neutral mutation is a nucleotide change in the DNA of the leading to the replacement of one amino acid by another amino acid possessing the same physicochemical properties.
example: AAA to AGA (Lysine to Arginine).
both these two amino acids are positively charged, so the charge of the protein will not change
The answer is water table. Water table is the boundary
between vandose zone and the zone of saturation. The unsaturated is the vandose
while the saturated is the groundwater zone. Water table is located in the top
of an unconfined aquifer, that can tell the level below which soil and rock are
saturated with water and the top of the zone that is saturation.
A minimum stream velocity <span>needed to keep a 6.4 cm diameter particle in motion must be 100 cm/s.
It can be concluded from Hjulstrome curve, a graph used to determine whether stream will transport, erode or deposit particles. The faster is the current, the heavier particles it could transport.</span>
