They are at the beginning because they absorb the energy from the sun and the energy or the sun gets transferred by each organisms
Answer:
organ systems
Explanation:
These include the chemical, cellular, tissue, organ, organ system, and the organism level. ... Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.
The true statements are the following:
3. Genes that are expressed in all cell types usually vary in their level of expression in different cell types.
4. Many differentiated plant cells can be fully de-differentiated and give rise to an entire plant.
Explanation:
Gene expression patterns are cell-specific, it means that in a cell genes are expressed at different levels in order to carry out their functions. In consequence, distinct gene expression patterns can be associated with distinct cellular types.
Plant cells that are differentiated may be reverted to their original (pluripotent) state and even they can be activated to produce a completely totipotent embryo that is then capable of producing differentiated plant tissues and organs.
Answer:
lipids
Explanation:
-Lipids are among the four biomolecules the others being proteins, carbohydrates and nucleic acids. Lipids are made of fatty acids and glycerol. --Fats (solid) and oils (liquid) are the major types of lipids.
-Butter is an example of saturated fats while oils are the lipids in liquid form.
