Enzymes are also known as Biological catalysts. An enzyme working at its maximum possible rate, where the substrate concentration is in excess is <span>V max.
</span><span>The reaction is slow because the molecules are moving slowly and they will not often collide with the active site of an enzyme, so the binding of an enzyme and substrate is rare.</span>
The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58
Difference between rock 3 and combined rocks
= 46.3 - 44.58
= 1.72 grams
therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.
Answer:
Explanation:
Environmental changes occurs from time to time, we have the short term changes that do not last for a very long time and the long term changes that last for a while. Accumulate of short term changes can extend to long term as some of the long term effects are as a results of short term changes in the environment.
Short term environment changes can be favourable to some organism and adversely affect others. Raining season causes increase in growth and development of most plant species but a long period of drought and dryness makes its hard for some plant to strive while some plants can strive well in long period of drought. This makes the two changes different, the both have individual effects on plants response.
<u>Answer:</u>
The correct answer option is B. Green wavelengths are the least used in photosynthesis.
<u>Explanation:</u>
Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.
From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.
Therefore, this reflection of green light makes the leaves to appear green.
