There are exchanges that happen continuously in our bodies. One exchange is the gas exchange, or respiratory, system. This is the system where carbon dioxide is released from the lungs into the air, and oxygen is taken into the lungs from the air. This exchange happens in the air sacs of the lungs called the alveoli.
The questions lacks the pedigree chart. The chart has been attached below.
Answer:
1/8.
Explanation:
The trait follows the autosomal recessive inheritance because the trait is seen only in the homozygous recessive condition only.
Patricia and Les has both the genotype Gg as clear from the pedigree chart. The cross between the patricia and les will give the genotype GG, Gg , Gg, gg. The probability of the affected child is 1/4 and the probability of a girl is 1/2.
The girl with affected galactosemia 1/4 × 1/2 = 1/8.
Thus, the answer is 1/8.
Answer:
A. Some were already resistant and were the survivors that could reproduce
Explanation:
Both resistant and susceptible insects will be exposed to DDT, but according to the evolution theory, it is expected that those insects that are resistant to the insecticide will be selected by natural selection. In consequence, the resistant individuals will survive to reproduce in the next generation.

Typically, a cell electric potential across the cell membrane varies between -40mV and -80mV. The electric potential in cells such as the neuron enable the cells to transduce the electric signal from stimuli across the nervous system. In other cells, the electric potential powers the running of molecular devices such as the flagella motor in sperm cells
