The disk part of the galaxy.
Answer:
50%
Explanation:
Glucose is a simple sugar with a total of 6 carbon atoms in its structure. Pyruvate has a total of three carbon atoms. Two molecules of pyruvate are obtained per glucose by glycolysis. None of the carbon of glucose is released in the form of CO2 during glycolysis. Therefore, the radio-labeled C-1 of glucose will be the component of the carbon skeleton of one of the total of two pyruvate molecules produced during glycolysis. So, 50% of the pyruvate will exhibit radioactivity.
Answer:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because
- <u><em>Respiration</em></u><em> is a process that occurs in the mitochondria.</em>
- <u><em>Diffusion</em></u><em> is a passive transport process that does not require energy.</em>
- <u><em>Cellular </em></u><em>recognition depends on membrane proteins that act as specific receptors.</em>
The answer is A and here is why:
We know that plants conserve and retain water. But the reason they do that is so they have enough water to survive. If the plants transpire more, they would lose water, so we know it isn't B. Same thing for C, if they give back 50-80% of the water, they are losing water. And it is obviously impossible for desert plants to make their own precipitation because precipitation is rain and snow and no plant can create that. So, using the process of elimination we can determine that the answer to the question is definitely A. effectively conserve and retain water
When you live closer to the equator, the climate is warmer than areas closer to the north and south poles. When elevation is higher the atmosphere is thinner and colder. Places near water tend to have more precipitation compared to places like deserts. Because there’s more water that can actually come out of the clouds.
I hope that helps at least a little
