Assume that you are a national official with the power to set policy for controlling environmental mercury pollution (Core Case

Kazeer [188]

Answer:

The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution. Policy:

Ban the incineration of waste
Require that coal-burning companies remove mercury from the coal
Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
Require that products containing mercury be labeled as such.
Set up programs that will recycle batteries and mercury-filled products.
Set up education programs that will help inform people about mercury pollution.

This policy works by addressing the ways to prevent and control mercury pollution.

Three problems that could result from implementing this policy:

Backlash from coal-burning companies.
It could take a while before we completely shift away from using coal.
Some of the programs that can be set up in this policy can be too expensive to set up and maintain.

<span>The answer is A. Invasive species are species that thrive unregulated in an introduced environment/ habitat and affect the biodiversity of the environment. They boom unchecked mostly due to lack of a natural predator. Therefore, introducing a predator will limit their growth. </span>

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father

prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
