We could possibly use water as a fuel source, rather than fossil fuels (which are limited)
Science has already developed something of the sort, and with using water as a fuel source for say vehicles and such, it's inevitable for a positive change to happen because there would be less carbon monoxide; which means less polution.
Ok... so pretty much you need to use the words they gave you and find the relation between them and connect them using the chart given in the textbook. I tried explaining my best. hope I helped
<span>The correct answer is 'metastasis'. This is the migration of cancer cells from one place to another in the body. They do this by travelling through the blood stream or the lymphatic system.
Mitosis is the process of asexual cell division. It produces cells that are identical to the original cell as one cell divides into two after replicating its organelles and genetic information. (Mitosis makes my toes.)
Apoptosis is controlled cell death. When cells are getting old then they need to be replaced. Old cells are programmed to 'die' at the correct time. The cell contents are recycled to make new cells.</span>
Random orientation of homologous pairs of chromosomes during meiosis I results in alternative arrangements that contribute to genetic variation in offspring. This is called "independent assortment".
<u>Explanation:</u>
The sets of homologous chromosomes, also recognized as bivalents or tetrads, align along the metaphase plate in a random order in metaphase I of meiosis I. Another way for cells to incorporate genetic variation is by spontaneous orientation. Mendel's independent assortment law stipulates that, independently of one another, the alleles of two or more different genes are sorted into gamets.
In other terms, for one gene, the allele that a gamete receives does not affect the allele that is obtained for another.Genetic recombination (by random segregation) and crossing over during meiosis creates daughter cells each containing different combinations of maternally and paternally coded genes.
