Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
Answer:
Bacteria provides vitamins to humans
Explanation:
The correct answer would be that bacteria provides vitamins to humans.
<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>
Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.
<em>Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.</em>
Answer:
The ocean.
Explanation:
It starts with the ocean and then there is evaporation condensation and precipitation and then runoff.
Pure water freezes at 32 degrees Fahrenheit, and at 0 degrees Celsius.

Answer:
Is released into the air through stomata
Explanation:
Oxygen and hydrogen both exists as gaseous molecules in the atmosphere. However, one of them (oxygen) is a product of photosynthesis while the other (hydrogen) is one of the constituents of the molecule that starts the process of photosynthesis.
According to this question, the X used in the attached diagram is the role of oxygen in photosynthesis. Oxygen is released as a product of photosynthesis and goes out of the plant into the air via the STOMATA. Hence, the gas released into the air via stomata is OXYGEN.
