B. they are single molecules...
Answer:
Our body cells require oxygen to release energy.
Explanation:
The oxygen that we take in during respiration is used to break down the food we eat to release energy from it. When we breathe in oxygen, it diffuses into blood from the lung, where it is transported by red blood cells to the entire body to be used to produce energy.
Answer:
The initial cost of solar panels is very high compared to using fossil fuels.

Answer:
Frequency of CW allele in the population= 0.41
Explanation:
A diploid organism has two alleles for each gene. So, a population of 100 plants will have total 100 x 2 = 200 alleles.
The each of the white colored plants have two copies of CW alleles and each pink flowered plant have only one CW allele.
Frequency of CW allele in the population = total number of white flowered plants x 2 + total number of pink colored plants / total population size x 2.
Frequency of CW allele in the population= 22 x 2 + 38 / 100 x 2 = 82 /200 = 0.41
Answer:
Geodesic Dome
Explanation:
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size.
