Before it hits your tap, unfiltered water from the Catskills winds its way through 6,000 miles of pipes aqueducts and tunnels.
Most of New York City's water -- 90 percent -- comes from the Kensico Reservoir. It holds 30 billion gallons and then travels to the ultra violet treatment facility in Westchester County, where 12,000 bulbs treat 1 billion gallons of water a day.
Hope this helps
Answer:
Kinases would stop working too.
Explanation:
Cells work constantly to maintain homeostasis or equilibrium within themselves. One of the mechanisms used for this purpose is feedback. As mentioned in the question, kinases put phosphates on proteins, and then, phosphatases take them off. Therefore, for phosphatases to work, kinases must be working at the same pace. By inhibiting the phosphatases the number of phosphate-proteins will be too high. This can be perceived by the kinases and they will automatically stop working since there's an excess of product. That process is called feedback.
Answer:
Vitamin C
Explanation:
Vitamin C is known as the ascorbic acid performs various functions in humans and is present as the constituent of the skin epidermis.
Vitamin C protects the skin from photodamage caused by the harmful UV radiations and helps in the synthesis of collagen, a type of connective tissue in the human body.
Vitamin C is involved in the hydroxylation of collagen synthesis which is important for the support of the epidermis and extracellular stability.
The deficiency of Vitamin C causes scurvy characterized y the fragility of blood vessels and bleeding.
Thus, Vitamin C is the correct answer.
Answer:
The correct option is: <em>a deficiency of dopamine in the substantia nigra.</em>
Explanation:
The substantia nigra is the principal site involved in the physiopathology of Parkinson´s disease.
Cells from this area degenerate and die progressively causing important degeneration in the central nervous system. The cells that die -with no known reason- are those that produce dopamine and proportionate dopaminergic innervation to the encephalon. In fact, almost all the symptoms exhibited by patients with the disease can be explained by the lack of dopamine in the substantia nigra.
This area uses the neurotransmitter to communicate neurons from the base ganglia. Ganglia are responsible of modulating and modifying movements.
The nigrostriatal system participates in planning and automatic execution of learned movements. When the ganglia activity decreases, so it does the amount and velocity of movements, something typical of the disease.
Answer:PLZ MARK ME THE BRANISET
By examining large sample sizes, Mendel showed that his crosses behaved reproducibly according to the laws of probability, and that the traits were inherited as independent events. Two rules in probability can be used to find the expected proportions of offspring of different traits from different crosses.
To find the probability of two or more independent events occurring together, apply the product rule and multiply the probabilities of the individual events. The use of the word “and” suggests the appropriate application of the product rule. To find the probability of two or more events occurring in combination, apply the sum rule and add their individual probabilities together. The use of the word “or” suggests the appropriate application of the sum rule.
