When deep-water waves move intoshallow water, they change into breaking waves. When the energy ofthe waves touches the ocean floor, the water particles drag along the bottom and flatten their orbit (Fig. ... Transitional waves occur when the water depth is less than one-half thewavelength (D < 1/2 L).
Question
What must happen before meiosis can begin
DNA replication must come first before meiosis to happen.Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy. and a paternal copy.
Answer: B. beta
Explanation:
Sickle cell anemia is a inherited disorder which occur due to mutation of gene responsible for synthesis of hemoglobin protein. Typically the gene which is responsible for synthesis of beta-globin protein which make the beta chains in the hemoglobin is affected by the mutation. As a result of this the red blood cells acquire a shape of sickle rather than round. Pain, cold, stress, dehydration and illness are the symptoms associated with this disorder.
The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)

Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
False.
It can either be called Dependent or Independent variable.
Hope this is correct :)
Have a great day
