Genes.
explanation:
- sections of DNA that contain information that determine your physical features are called genes. Since you have two pairs of chromosomes, you also have two pairs of genes, one from your father and one from your mother. These pairs of genes then determine certain physical features or traits(phenotypes).
Answer:
Chloroplasts are organelles found in only plant cells that convert sunlight into energy (photosynthesis)
the cell membrane is the circle surrounding the cell which protects the inside of the cell from the outside of the cell
the cell wall is a wall found outside the cell membrane which is found only in plant cells
The answer would be Prevent yourself from knowing what was in the pill bottles, and distributed the bottles randomly to the subjects
When researcher know which group got the treatment and which group got placebo, they might be biased. It will be better if the researcher is "blinded" and ask third party to help labeling the drug. The drug should be distributed randomly to makes the subject in control and treatment group as similar as possible.
Answer:
The correct answer is option A) "0.0 mM sucrose".
Explanation:
Since single-celled Paramecium use their contractile vacuole to osmoregulate upon hypotonic environments, it is expected that a condition where no sucrose or salt is added is the condition where the contractile vacuole would be most active. In this extremely hypotonic condition cells tend to absorb high quantities of water, the contractile vacuole pumps water out of the cell to regulate its osmotic pressure.
The answer could possibly be natural selection or survival of the fittest
