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.
Answer: S- phase of cell cycle
Explanation:
Cell cycle is a cyclical process taken place in a cell leading to duplication of its DNA and division of cytoplasm to form two daughter cells.
The S phase of a cell cycle is an important part of the cycle which is found during interphase stage before either mitosis or meiosis.
The S phase of cell cycle is responsible for the replication of DNA. This replication DNA causes it to double before it enters mitosis or meiosis.
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Answer:
Genetic, geographic & cultural factors that cause sickle-cell anemia. It is important to note that even genetic diseases are caused by multiple social, environmental and biological factors. This is particularly true in the case of sickle-cell anemia, a genetically inherited blood disorder usually found in people with West African ancestry (PBS 2001).
Answer:
It's possible.
Explanation:
If the recently formed metamorphic rock keeps on warming, it can ultimately soften and become molten (magma). At the point when the liquid stone cools it frames a molten rock, which is igneous. Metamorphic rocks can form from either sedimentary or volcanic/igneous rocks.
