Answer:

Crossing over

Explanation:

Prokaryotic cells are cells that do not possess a membrane bound nucleus to house their genetic material e.g bacteria while eukaryotic cells possess a membrane bound nucleus that houses their genetic material e.g plants.

One important characteristics of prokaryotic cells is that they do not undergo any form of sexual reproduction, hence, cannot undergo MEIOSIS, which only occurs in sexual reproducing organisms. Prokaryotes reproduce asexually by binary fission.

Crossing over is a unique process that only occurs during meiosis. Since prokaryotic cells do not undergo meiosis, this means that crossing over is the difference between prokaryotic cells and eukaryotic cells in this question.

Explain what happens during the process of fertilization using the following terms: diploid, egg, haploid, sperm, and zygote
lisov135 [29]

Answer: During fertilization, an egg with haploid number of chromosomes unites with a sperm cell with a haploid number of chromosomes to form a zygote with a diploid number of chromosomes.

Explanation: Fertilization is a process in which a sperm cell from a male fuses with an egg from a woman to form a zygote. Sperm cells and eggs are diploid cells and they have half the number of chromosomes as the parent cell. During fertilization the haploid chromosomes from the sperm cells combine with the haploid chromosomes from egg to form a zygote with diploid chromosomes. Diploid cells have the same number of chromosomes as the parent cell. Haploid cells are produced in meiosis while diploid cells are produced in mitosis.

if the forest changed to more sandy it would let lighter mice live there to but the dark mice would still live because it is not all sand i like it would be equal amount of dark and light mice because they would both have there spot to hide and just as vulnerable if the switched spots
