I) I think four gametes are possible in either a male or a female. That is; GY, gY, Gy, and gy.This is because both traits are heterozygous which means for a certain gene there are two different alleles. While in the case of homozygous there would only be one type of gametes since for a given gene there are two similar alleles. ii) I think crossing over or recombination could cause the alleles that are linked with the wing color and the eye color genes to be exchanged between the two chromosomes in a pair, thus, resulting to new combinations of alleles. The final result would then be an increase in possible genetic variation.
To answer the question need to watch this video:

Answer:
The correct answer is - A large amount of sea life is being taken from the ocean to feed other creatures.
Explanation:
In this video, Greenberg found out that there is a terrible problem as using fishing on a large scale causing harm to marine life and resulting in the extinction or endangering of species on large scale or taken from the ocean to feed other creatures.
To correct this he talks about the overfishing problems He talks about preventing people from overfishing so many fish do not have to face problems of extinction.
"Sex Cells" or "haploids" are needed in order to add variation in DNA. If there was no "haploids" (which are just cells with 23 Chromosomes), then the female would not need the male for reproduction, basically meaning birth of an identical twin to the mother. The two haploids, the female's ova (Egg) and male's sperm meet, creating a zygote, or a fertilized egg.
This makes sure there is "immediate variation", and it isn't just ten generations of the same "Bob"!
Answer:
Contain gentic material
both have DNA
Explanation:
Prokaroytes dont have organ systems
and the rest are incorrect
It is not just the muscle cells that respire. All cells in the body need oxygen for respiration and all cells need to get rid of the carbon dioxide that they produce. In the lungs oxygen is taken from air into the blood and the blood transports the oxygen to the cells in all tissues of the body.As the muscles use the oxygen up,carbon dioxide is produced and absorbed into the blood. And this de-oxygenated blood is pumped back to the heart then on to the lungs. The lungs get rid of this carbon dioxide, and breathe in more oxygen.
Hope this answered your question.
