Blood<span> is a heterogeneous </span>mixture<span> because the </span>blood<span> cells are physically separate from the </span>blood<span> plasma. The cells have different properties than the plasma. The cells can be separated from the plasma by centrifuging, which is a physical change. Since it can be separated mechanically, it is not a chemical compound</span>

because it produces smoke and it's smell attracts others.
Answer:
Viruses replicate only inside host cells.
Explanation:
<u>Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells. </u>
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
<em>Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory. </em>
Answer:
1. B. NADH
2. B. hydrolysis of ATP.
3. C. ATP is produced from protein.
4. Option C.
5. Option C. Oxygen
6. Option D. Glucose.
7. Carbondioxide.
8. Metabolism.
9. Electron carriers.
10. Electrons.
Explanation:
Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.
Explanation:
Answer:
In cats, there are two types of ears: normal and curly. A curly-eared cat mated with a normal- eared cat, and all of the kittens had curly ears. Are curly ears a dominant or recessive trait? Explain.
CC x cc = Cc, Cc, Cc, and Cc 4:0
All kittens have curly ears, this is as a result of the dominance of curly ears to normal ears that is recessive
