sec(A) = 5/3 ⇒ cos(A) = 3/5
Angles A and C are complimentary (they sum to 90°), so
sin(C) = cos(A) = 3/5
since sin(90° - x) = cos(x) for all x, and in turn
csc(C) = 1/sin(C) = 5/3
Answer:
A) two examples of environmental factors that may impact salivary peroxidase activity are pH and temperature. All enzymes have an ideal pH range. When the environment has a pH in that specific range, the enzymatic reaction rate will be the fastest. However, when the environment deviates from the pH range, the enzyme's reaction rate will be slower. Furthermore, when the pH is too far off that ideal pH range, then the salivary peroxidase may denature and unravel, due to it being a protein. Another factor is temperature. When temperature is higher, the reaction rate increases. However, when the temperature is lower, the reaction rate decreases. However, when the temperature gets too high, then the enzyme may denature.
B) The effects of defects in the thiocyanate transport channels would be for lactoperoxidase to not be able to function properly, causing defects in the defense against pathogenic microorganisms in the intestinal tract of newborn infants and defects in sterility of the secretions for the respiratory tract.
In order for lactoperoxidase to function properly, thiocyanate is necessary. Because of this, Therefore, thiocyanate is likely a cofactor, allowing for lactoperoxidase to function.
Because of this, if the thiocyanate transport channels are defective, thiocyanate can likely not reach the lactoperoxidase, and can therefore not bind to it. This defect in the transport channels would mean that thiocyanate cannot carry out its necessary function of activating lactoperoxidase.
Answer:
the number of houses ≈ 8.25 million houses
Explanation:
Given that:
A typical house in the United States uses about 10,900 kWh,
1 TWh (terawatt-hour) =1×10^6 GWh (gigawatt-hour) =1×10^9kWh (kilowatt-hour)
The three Gorges Dam in China produces about 90TWh of electricity each year. If it was to to be built in the United states, the number of houses such a plant would be able to provide the electricity for in a year is given as:
Number of houses = Amount of electricity produced in a year / amount of electricity used by each house.
Number of houses = 90 TWh / 10,900 kWh = 90 × 10⁹ kWh / 10,900 kWh = 8256881
Therefore the number of houses ≈ 8.25 million houses
Answer: A good scientific question is one that can have an answer and be tested. "Why is that a rock?" is not as good a question as "What are rocks made of?" 2. A good scientific question can be tested by some experiment or measurement that you can do.
Mount saint helen is an active stratovolcano and it was formed due to the subduction of the Juan de fuca plate.
