A student conducted an investigation to study phototropism in grasses. The only difference between the control group and the exp

erimental group was light conditions. The control group was provided full light, while the experimental group was shaded on one side. The diagrams show the average heights and positions of blades of grass in the investigation. Which statement best explains why the grass tips of the experimental group bent toward the light?
a) Water evaporated faster on the side of the plant having full light.
b) Light sensors in the grass tips stimulated a hormone in the shoot system.
c) The xylem in the root system absorbed more nutrients from the shaded side.
d) The side facing the light has a greater chance of absorbing carbon dioxide from the atmosphere.

Answer:

Option-B

Explanation:

Phototropism refers to the movement of plants in response to light. The mechanism of phototropism involves the photoreceptors which respond to a different wavelength of light: the phytochromes to red light, cryptochromes to blue light and the phototropin to the UV light.

Plants integrate the signals obtained from these receptors and then activates the gene which will be involved in the phototropism.

The gene could be the production of the auxin hormone and the PIN proteins which helps in the distribution of the auxin in the plants. Due to the production of this hormone and its distribution in the shoot, the grass tips bend towards the light.

Thus, Option-A is correct.

What happens to the CO2 released by the body?
Sladkaya [172]

Answer:

When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.

The same rabbit population is seen from year to year because the food supply is greater in the spring, so it can support a large
solniwko [45]

The same rabbit population being constant because the food supply is greater in the spring and supporting a larger number of animals is a false statement.

<h3>What is Population?</h3>

This is defined as the total number of organisms in a particular place at a given period of time.

Factors such as topography, human influence are other factors except food supply which influences rabbit population which is why False is the correct choice.
