Answer:
Centripetal force is perpendicular to the velocity of the satellite.
Explanation:
because there is no friction or wind resistance, the speed of the satellite remains the same
Answer:
Enzyme-controlled chemical reactions combining carbon dioxide and glucose water. The photosynthetic rate is affected by the temperature much like any other enzyme-controlled reaction.
Explanation:
At low temperatures, the number of molecular collisions between enzymes and substrates limits the photosynthetic rate. Enzymes are denatured at high temperatures.
Enzymes are protein molecules used in biological reactions by living organisms. The proteins are folded in a very specific form, which enables them to effectively bind to the molecules of interest. The enzymes used for photosynthesis perform less efficiently at a low temperature between 32 and 50 degrees Fahrenheit 0, 10, and 10 degrees Celsius, which lowers the photosynthesis rate.This will lead to lower glucose synthesis and slow growth. In the case of plants in a greenhouse, this is prevented by installing a greenhouse heater and thermostat.
Answer:
True
Explanation:
Ice pellets are rain drops that have frozen <em><u>before</u></em> they hit the ground.
(They freeze while they're still in the air)
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
