The covalent bonds between the oxygen and the hydrogen atoms result from a sharing of the electrons. This is what holds the water molecules themselves together. The hydrogen bond is the chemical bond between the water molecules that holds the mass of molecules together.
Answer:
Trees create their own food.
Explanation:
Trees like many other plants use photosynthesis to make or "produce" their own food using carbon dyoxide, water, and energy from the sun. This then creates glucose, their own food.
They form into more molecules as they produce more
Answer:
The correct response will be "Tends to help turn towards the light".
Explanation:
- The eyespot should not be an eye or an observer but somehow it needs to respond to adjustments in some kind of a light source's brightness.
- The Euglena may do the photosynthetic activity to prepare the meal for themselves. The eyespot makes it travel toward illumination, the source of power for photosynthetic organisms.
Answer and Explanation:
The magnitude of the foliar area defines the capacity of the plant in intercepting photosynthetic radiation, which is the <em>principal source of energy used by plants</em> for the tissues and food elaboration. The bigger the foliar area is the better photosynthetic capabilities the plant has. <em>Variations in the size of leaves correspond to variation in the amount of solar radiation intercepted</em>. The spatial arrangement of leaves in the whole plant is also related to the individual strategy for intercepting radiation.
The plant shown in the picture seems to have a very developed aerial part, growth in height, long stems, and huge leaves with an alternate arrangement. They probably become important competitors to their neighbors because of their size. Competition is probably related to space, but considering that all the species that are near this plant are much smaller, competition might be <em>related to space in the ground and not necessarily competition for aerial space
. </em>
