e? (1 point)
o positive phototropism; auxin will accumulate on the side nearest to the light source
O negative phototropism, auxin will accumulate on the side away from the light source
O positive phototropism; auxin will accumulate on the side away from the light source
O negative phototropism; auxin will accumulate on the side nearest to the light source
normally, roots exhibit negative phototropism and positive geotropism. but with the absence of gravitational force, there's no way there will be negative geotropism
If a plant is grown in the absence of gravity, roots will exhibit NEGATIVE PHOTOTROPISM, and auxin hormone will accumulate on the side away from light.
Phototropism can be defined as the growth or movement of an organism (e.g., a plant) in response to light stimuli.
Phototropism may be caused by specific stimuli and chemicals such as hormones.
Positive phototropism occurs when a plant (or its parts) grows towards the light source, whereas negative phototropism occurs when a plant grows away from the light source.
In conclusion, if a plant is grown in the absence of gravity, roots will exhibit negative phototropism, and auxin hormone will accumulate on the side away from light.
<em>The blood brings bicarbonate to the lungs, and then it is exhaled as carbon dioxide. The kidneys also help regulate bicarbonate... it is excreted and reabsorbed by the kidneys.</em>
<em>The body's main response is to get rid of more carbonic acid and hold on to as much bicarbonate base in the kidneys as it can.</em>
La mejor razón para usar una sonda de temperatura en lugar de un termómetro es registrar mediciones continuas durante varios minutos. La temperatura es la cantidad física que expresa el frío y el calor. Se mide con el termómetro.
