Large trees and ferns need water to survive. This suggests that the biome was once very different from the desert it is today. #globalwarming lol
Hello. This question is incomplete. The full question is:
"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation?
"
Answer:
You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.
Explanation:
Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.
If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.
Answer:
Explanation:
Interesting question. Consider the formula that governs the gravitational formula
F = G * m1 * m2 / r^2
G is the gravitational constant. It does not change no matter where you are in the inverse, nor is it found to be different under normal circumstances. Since you have asked this in biology, you can assume that the circumstances are always normal./
m1 and m2 are masses in kg. The mass is invariant as well anywhere in the universe, except perhaps near or in a black hole.
r^2 is a distance in meters.
So the Force of gravity (in Newtons) varies directly as the masses involved and inversely as the distance squared.
Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
A and E to be exact with this answer
