Answer:
Explanation:
The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled
Answer:
3.6 µg of Vitamin B12, 2.3mg of Vitamin B6, 30.1mg of Niacin B3, 1.8mg of Vitamin B2
Explanation:
Total amount of Vitamin B in 100 grams of Milo powder contains 3.6 µg of Vitamin B12, 2.3mg of Vitamin B6, 30.1mg of Niacin B3, 1.8mg of Vitamin B2. In milo powder, almost all types of vitamin B are present which make it good for our health. This milo powder also contains 54mg Vitamin C, 594mg of Calcium and 21.8mg of Iron so the total amount of Vitamin B is more about 34.2 mg.
Answer:
A. the heterozygote advantage
Explanation:
Heterozygote advantage is the condition where the heterozygous individual has higher relative fitness than both homozygous dominant and homozygous recessive individual. This means that the heterozygote individual has higher chances of surviving than both the homozygous counterparts. Sickle cell anemia is a recessive inherited disorder in which oxygen carrying hemoglobin has an abnormal structure. Hence, the resultant RBCs are not spherical but have crescent sickle shape. The oxygen carrying capacity of such RBCs is drastically reduced but they are unaffected by malarial parasite due to their abnormal structure.
- A person with both the recessive genes for sickle cell would not be able to survive due to insufficient oxygen transport in body.
- A person with both the dominant genes would be free of sickle cell anemia but in case of malaria would not be able to survive as the normal RBCs would be hijacked by the parasite.
- A hetrerozygote would survive both in malaria and sickle cell condition since he has enough normal RBCs for oxygen transport but also has sickle cell RBCs which are unaffected by malarial parasite.
