False. That question doesn't really make sense also but it should still be false given the context.
Answer:
Providing a controlled source of water vapour through which water can be vaporized into the plant envoirment.
Explanation:
Humidity ratio is the ratio of the mass of water in air to the mass of dry air. Humidity is needed in some conditions where the air is very dry. In a very dry air setting, there can be excess moisture loss from the plant surface, increasing the Humidity ratio can counter this effects and reduce excess moisture loss.
Q5.
<span>The
answer is A. In thermodynamics, the first
law of conservation states that energy can never be destroyed or created but
can only be transformed from one form to another. Therefore part of the
electric energy was converted to light energy while the other dissipated as
heat. However, the summation of the energy
of these tow outputs in joules remains
the same as initial electric energy.

Q6
<span>The answer is B. This is because
the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they
turn electromagnets that convert the mechanical energy into electrical energy</span>
Answer:
C) The pea plant would be shorter with more branches compared to wild-type plants.
Explanation:
Gibberellic acid stimulates the stem growth by promoting elongation and cell division, so having this compound's gene underexpressed will make the plant shorter. On the other hand, cytokinins are located in young cells, particularly the buds, and stimulates its lateral growth. Having a plant with a overexpressed cytokinins gene will make the plant have more branches compared to wild-type plants.
The correct answers are:
sin(D) = 24/25
tan(D) = 24/7
sin (E) = 7/25
