The metaphase is the second stage of cell division when chromosomes attach to the spindle fibers
Valence of oxygen is negative two.
<span>The increase in the use of wind energy does not have to affect the energy supply of coal, since they are not related in any way and do not depend on each other. It's totally out of logic. They are different energies, the wind energy should not affect the energetic consumption of coal for the simple fact that coal is not necessary to produce wind energy, but it could be said that the demand for coal could be reduced by a small percentage only If the wind energy is used much more.</span>
Answer:
Carbohydrate, proteins, and lipids
Explanation:
<em>The organic molecules that can be derived from eating foods are carbohydrate, proteins, and lipids.</em>
<u>Carbohydrates are general derived from starchy foods such as grains, proteins are derived from eating of foods that are rich in proteins such as meat, milk, etc, while lipids are derived from eating fat/oil-based foods such as butter, avocados, etc.</u>
Nucleic acids are not derived directly from foods. They are monomers of proteins and hence, they are only derived from breaking down proteins.
Answer:
Photons
Explanation:
Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.
