Answer:

The Clean Water Act (CWA) can be considered as one of the effective program which impacted the water quality in the United States. Under this Act, quality standards for surface water were generated.

This Act has set wastewater standards for the industries and it ensures that industries do not pollute the clean water. The Clean Water Act (ACT) made it unlawful to discharge any pollutant in waters and set a fixed amount for it. Beyond that amount, polluting water is considered to be illegal.

Why are enzymes important for our bodies
valentinak56 [21]

Answer:

Because enzymes have many functions as chemical catalysts in numerous chemical reactions (for example in metabolism). By lowering the activation energy, they make it much easier to carry out reactions. They are also indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolyzing ATP to generate muscle contraction, and also transport cargo around the cell as part of the cytoskeleton. Other ATPases in the cell membrane are ion pumps involved in active transport.

Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of gly
dem82 [27]

Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of glycolysis that is catalyzed by pyruvate kinase.

<h3>Gluconeogenesis:</h3>

The tissues of some organs, including the brain, the eye, and the kidney, use glucose as their primary or only source of metabolic fuel. Glycogen stores become exhausted during a protracted fast or intense exercise, and glucose must be created from scratch to keep blood glucose levels stable. The process through which glucose is created from non-hexose precursors such glycerol, lactate, pyruvate, and glucogenic amino acids is known as gluconeogenesis.

Glycolysis is effectively reversed during glucose synthesis. However, gluconeogenesis makes use of four distinct enzymes to skip the three highly exergonic (and essentially irreversible) phases of glycolysis. The pyruvate carboxylase, PEP carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase enzymes are specific to gluconeogenesis. Gluconeogenesis can only take place in particular tissues because these enzymes are not found in all cell types. In humans, the liver and, to a lesser extent, the renal cortex are the primary locations for gluconeogenesis.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages​
elena-s [515]

Answer:

75years

Explanation:

Let the Father's age be represented by 2x

Let the Son's age be represented by x

Five years ago;

Man's age will be = 2x - 5

Son's age will be = x - 5

If the ratio of their ages five years ago was 9:4, then;

2x - 5/x-5 = 9/4

4(2x - 5) = 9(x - 5)

8x - 20 = 9x - 45

- Collect like terms

-20 + 45 = 9x - 8x

25 = x

Hence, the son's age = 25 years

If x = 25, the father's age (2x) will be 2 × 25 = 50years

The sum of their ages will be = 25years + 50years = 75years
