Answer:
Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells
Explanation:
Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.
A natural disaster can cause an ecosystem to obliterate completely.
On March 18th, 1980, Mount St. Helens erupted in Washington. The eruption caused over 19 miles of destruction. Nearly 40 years later, the surrounding area still showed signs of recovering. The hot blast of volcanic ash destroyed the ecosystem around the volcano, and while the ecosystem was destroyed, eventually the ecosystem slowly grew back to flourishing.
Answer:
The circulatory system interacts with every organ and system in the body hence, it is vital for every organ and system to function properly.
The circulatory system carries oxygen to the lungs and takes the waste materials out of it. Hence, a malfunction in the circulatory system can cause the respiratory system to not work properly. Severe damages will be caused to the body if oxygen is not taken to and from the lungs.
The circulatory system is also involved in carrying waste materials to the kidneys. It helps carry the waste materials out of our bodies. Malfunctioning of the circulatory system can cause no excretion of wastes from the body which will eventually lead to the death of the organism.
