Answer:
It speeds up the reaction rate
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Answer:
personality

do you mean traits or characteristics
B
The European weather model sometimes differ from predictions made by the American weather model because <u>The two models use different types of data measurements</u>
<u></u>
<u>The amount of solar energy that reaches Earth</u> is changed by the Milankovitch cycles
Explanation:
(I)
Remember that in the United States, they use different SI units as compared to Europe. For example, Europe uses degrees Celsius as a measure of temperature while the United States uses Fahrenheit. In addition, the United uses Pounds for weight measurements while Europe uses Kilograms and grams. The US uses miles while Europe uses kilometers. The United States uses yards while Europe uses meters.
The differences can cause a difference in the input and output measurement gotten from the models. However, the models are the same because the basic principles of weather across the world are the same.
(II)
Milankovitch cycles are differential changes in the earth as it revolves, around the sun, in its orbit. They explain the changes in the orbital eccentricity of the earth's orbit, the changes in the tilt of the earth (obliquity), axial and apsidal precessions. All these affect how the earth is oriented, in space, towards the sun. The orientation affect how the sun rays ‘hit’ the earth. Differences in how different places on earth receive the sunlight affect the climate of the regions. These changes occur very slowly, relative to our time, hence the changes also are hard to perceive except over decades and millennia.

Answer:
Primary role of vitamin D is to absorb calcium. It along with calcium, helps to keep bones strong. It also help to make the bone brittle.
Deficiency of vitamin D causes the bones to lose their strength. If body does not get enough vitamin D, then absorption of calcium is lost resulting in osteoporosis in adults and rickets children.
