Answer:</h2>
Blood Is A Heterogeneous mixture.
<h2>
Explanation:</h2>
Heterogeneous mixture is a mixture that is made up of different substance that remains physically separated which means the cell organelles (Red blood cells, white blood cells, platelets etc.)present in blood does not mix completely and hence get precipitated after kept still for a while.
There are three ways to identify a Heterogeneous mixture.
- It has chunks of stuff that you are able to see with your eyes.
- It appears cloudy(blur).
- After a while, the substance will separate into layers at settle at the bottom(gets precipitated).
Result: Blood is a Heterogeneous mixture

Answer:
Has three dominant alleles
Explanation:
Skin colour is a polygenetic inheritance and it is controlled by three genes pairs of alleles. The human skin is determined by the amount of melanin it contains. A combination of melanin producing alleles determines the skin color.
In the above question, the person has a skin color that is midway meaning only half of the alleles produced melanin. The total number of alleles is 6 and half of it is 3. So, only 3 alleles were dominant and the remaining three were recessive.
Answer:
B. G1, S, G2, Mitosis, Cytokinesis
Explanation:
G1 is the first stage of the cell cycle, and it is essential for cell growth.
Next, the S (Synthesis) phase occurs. This phase involves DNA synthesis to prepare the cell for division.
G2 is the next phase, and it involves preparing and growing the cell for mitosis.
Mitosis is the next stage, where the cell divides into 2.
Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.
So, the correct answer is B. G1, S, G2, Mitosis, Cytokinesis
