Yes and no, without mutations, there would be no biodiversity, a lack of biodiversity results in vulnerability for excitation. Mutations can also be negative and debilitating for organisms. Without mutations, there would be no differentiation in the genetic pool.
Macronutrients are a substance required in relatively large amounts by living organisms, in particular.
a type of food (e.g., fat, protein, carbohydrate) required in large amounts in the human diet.
a chemical element (e.g., potassium, magnesium, calcium) required in large amounts for plant growth and development.
a chemical element or substance required in trace amounts for the normal growth and development of living organisms.
The type of weathering is mechanical and the process is abrasion
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.
