<u>Complete Question:</u>

Which of the following is most responsible for reducing the availability of fresh water in this country?

A. aquifer depletion,

B. reservoir evaporation,

C. non-point source pollution, or

D. boat and watercraft emissions.

<u>Correct Option:</u>

The non-point source pollution is most responsible for reducing the availability of fresh water in this country.

<u>Option: C</u>

<u>Explanation:</u>

The contamination which is a mixture of wide area contaminants, instead of common known factors like drainage pipes, is understood as non-point source pollution. Runoff is commonly correlated with non-point source contamination, because water is drained into streams or rivers after pollutants are collected from outlets such as parks, parking lots or construction sites.

Surplus fertilizers, herbicides and insecticides from farmland and populated areas can contain non-point source emissions. Carbon, grease, and toxic substances derived from industrial wastewater and electricity. Sediment from poorly controlled building sites, farm and woodland areas, and diminishing stream banks, triggering a decline in the nation's freshwater supply.

Among the products of glycolysis, which compounds contain energy that can be used by other biological reactions?a) ATP onlyb) py

Sunny_sXe [5.5K]

Answer: A (ATP only)

Explanation:

Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.

Answer is ATP only

What are the advantages of Using Both Types of Reproduction

ra1l [238]

Answer:

Leads to variations. Variations which are desirable often show hybrid vigour. High adaptability of individuals to changing environmental conditions. Variations provide a basis for evolutionary changes. The population can increase rapidly when the conditions are favourable. Only one parent is needed. It is more time and energy efficient as you don't need a mate. It is faster than sexual reproduction.

What ARE The relationship of genetics and environment in effecting evolutionary changes

Lubov Fominskaja [6]

The environment can influence the evolutionary changes so that the organism will be best suited to survive in that area. Genes that are useless in that specific environment will eventually be replaced with more useful traits as the species evolves.

Hope that helps

The pedigree below tracks Duchenne Muscular Dystrophy (DMD) through several generations. DMD is an X-linked recessive trait.

Goshia [24]

Answer:

- If individual III-1 marries an unaffected, non-carrier female, none of their children will have DMD

Explanation:

From the options, the only correct statements is that <em>If individual III-1 marries an unaffected, non-carrier female, none of their children will have DMD</em>

<u>DMD is an X-linked recessive trait, meaning that a male individual is either affected or unaffected (can never be a carrier). III-1 is unaffected and if he marries an unaffected, non-carrier female, it means that none of their children will have DMD.</u>

All the children of II-4 and II-5 will always come out with DMD because both parents are affected.

Individuals I-1 and II-1 are males. A male can never be a carrier in for X-linked traits. He is either affected or unaffected and as shown by the pedigree, both males are unaffected (unshaded).
