Answer: Lac operon
Explanation: the same cells when grown in glucose media utilize the glucose as source if energy by blocking the activity of the enzyme beta- galactosidase. the operator site of the operon is blocked thereby preventing the activity of the collective functional genes.
Answer: Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFW genotype is 96.
Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFB genotype is 12.
The population may be evolving because the actual number of individuals with each genotype differs from the expected number of individuals with each genotype.
The population is not at Hardy-Weinberg equilibrium.
Explanation:
The FB allele should accounts for 120 of the alleles (40 × 2 = 80 in FBFB wolves, + 40 × 1 = 40 in FBFW wolves).
the FB allele would make up 20% (120/600) of the total alleles in the population, so the value of p would be 0.2. The allele frequencies of the population must add up to one for it to be valid (what this means is p+q=1); therefore, since the value of p is 0.2, and the value of q is 0.8.
According to the Hardy-Weinberg equation, the expected frequencies of the genotypes would add up to 1.
= p2+2pq+q2
= 1
or
= 0.22+2(0.2)(0.8)+0.82
= 1
or
= 0.04+0.32+0.64
= 1
In most ecosystems, the original source of energy for the living things in the system is the sun.
Answer:
gas
Explanation:
Gas has a volume but doesn't take specific shape.
