The mother's genotype can be either 
or 
.
For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.
The circled male child is free from the disorder (
) while the females are carriers ().
The male inherited the healthy allele, 
, from the mother.
The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.
This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.
Thus, the possible genotype of the mother are and .

Answer:
the answer is D) a negative charge
Answer:
A. increased
Explanation:
In general, life has gotten more complex through history. However, there have been times when biodiversity as been substantially reduced. (We may be in one of those times at present.) We cannot say that the complexity of life has increased <em>throughout</em> the history of any particular place, but we can say the long term trend has been one of increase.
Answer:
The facilitated diffusion is a type of passive transport affected by different factors including the temperature and the pH level. The facilitated diffusion process is produced by proteins that enable the movement of molecules between both sides of the cell membrane.
The pH level depends on the ion gradient and this factor modifies the diffusion rate of the buffers between both sides of the cell membrane. Moreover, the temperature is a factor that modifies the ionic charge of molecules, as well as the structure and the porosity of pores that facilitate the interchange between both sides of the cell membrane
