Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
1. I’m not really sure how to answer it, i think it’s parasitic
2. The tick is the parasite since the human is the host
3. It’s symbiosis bc it’s a long term biological interaction between two different biological organisms (the human and the tick) and in this case it’s parasitic bc one benefits off the host but it’s harmful towards the host so it doesn’t benefit each member.
Hope that helps :)
C. a toy train is the item that has characteristics similar to a scientific model.
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die.
B.
Both processes have a growth period called interphase, in which a cell replicates its genetic material and organelles in preparation for division. The two cells that result after meiosis I enter meiosis II very quickly, during the brief interphase period, no further DNA replication takes place.
C.
