Answer:
B. 0.42
Explanation:
Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1
According to the given information, the frequency of one allele in the population is= 0.7
This means that the frequency of the other allele would be= 1-0.7 = 0.3
Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42
Option a is the correct answer
people do not use water correctly and waste it
Answer:
<u>Carbon Dioxide limits photosynthesis at a concentration of around 400 ppm (ambient concentration) in low light.</u>
Explanation:
Limiting factors affect the photosynthetic rate, decreasing the potential amount of carbohydrate made via photosynthesis. Carbon dioxide is essential to this form of biosynthesis- it provides the inorganic carbon that is integrated into carbohydrate molecules.
Carbon dioxide is typically present in the atmosphere at concentrations of 0.04%. Light intensity typically cause stomata to open, and increase CO2 uptake. Higher concentrations of CO2 up to 0.1%, cause dramatic increases in the photosynthetic rate.
Low light, thus means less stomatal opening, and less CO2 uptake. As low light intensity can be limiting, it lowers the concentration of Carbon dioxide at which the rate becomes constant.
Answer:
Energy is used up while running, and cellular respiration needs oxygen to produce more energy. Energy is used up while running, and cellular respiration needs carbon dioxide to produce more energy.
