Answer:
B. Each allele must be equally beneficial.
Explanation:
There are five main requirements to achieve Hardy-Weinberg equilibrium:
- No mutation
- No migration or gene flow
- Very large population
- Random mating
- No natural selection
The red-purple allele difference has to do with #5, <u>no natural selection.</u> This difference in alleles "Therefore, more of them will survive and reproduce" indicates natural selection, and hence evolution, may occur, which cannot happen in Hardy-Weinberg.

Iron deficiency is considered the first nutritional disorder in the world. And it is that iron is essential for our body since it participates in many metabolic processes, especially in the formation of hemoglobin (Hb) contained in red blood cells.
Hemoglobin is primarily responsible for transporting oxygen to tissues and is also essential for DNA synthesis, cellular respiration and for key metabolic reactions to be carried out, as well as for proper functioning of the immune system is for this reason. The body feels fatigued due to lack of iron.
Explanation:
Iron deficiency and anemia occur mainly in women. The causes are several, and range from poor diet (following a very strict vegetarian diet, not consuming red meat, drinking a lot of tea or a lot of fiber), taking medications that prevent its absorption, being pregnant or having insufficient iron absorption, which is It is mainly due to intestinal surgery or diseases of the intestine, such as Crohn's disease or celiac disease.
The main cause of iron deficiency and anemia is blood loss. “In developed countries it is mostly due to menstrual losses in premenopausal women and digestive bleeding in men and postmenopausal women
