Answer:
Explanation:Cell membranes act as barriers to most, but not all, molecules. Development of a cell membrane that could allow some materials to pass while constraining the movement of other molecules was a major step in the evolution of the cell. Cell membranes are differentially (or semi-) permeable barriers separating the inner cellular environment from the outer cellular (or external) environment.
Water potential is the tendency of water to move from an area of higher concentration to one of lower concentration. Energy exists in two forms: potential and kinetic. Water molecules move according to differences in potential energy between where they are and where they are going. Gravity and pressure are two enabling forces for this movement. These forces also operate in the hydrologic (water) cycle. Remember in the hydrologic cycle that water runs downhill (likewise it falls from the sky, to get into the sky it must be acted on by the sun and evaporated, thus needing energy input to power the cycle)
<span>Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion.
The absorption spectrum of chlorophyll a alone underestimates the effectiveness of certain wavelengths in driving photosynthesis. This is partly because accessory pigments with different absorption spectra are also photosynthetically important in chloroplasts and broaden the spectrum of colors that can be used for photosynthesis.</span>
Answer: Firstly it should be noted that, the chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. On this wise, their genomes would be more similar to each other than are the genomes of the five tree finch species. Secondly, they should be limited to the six islands that most recently emerged from the sea.
Thirdly, they should share fewer anatomical homologies with each other than they have shared with the tree finches.
Fourtly, their genomes should be more similar to each other than are the genomes of the five tree finch species.
Answer:
The answer would be brain stem!
Explanation:
plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis
