Answer:
the molecules in water are spread apart enough that it can flow but tignt enough so that it isn't a gas. water is flowy and can conform to the shape that of the container that it is consumed within.
Glucose is the main provider of energy for the brain and the nervous system. Because the brain is so rich in nerve cells, or neurons, it is the most energy demanding organ, using one half of all the sugar energy in the body. Brain functions such as memory, thinking and learning are closely linked to glucose levels and how efficiently the brain uses this fuel source.
<em>You will find the cell in metaphase and the draw of the gametes in the attached files</em>
Answer:
Gametes: RY, RX, rY, rX
Explanation:
During metaphase I, homologous pairs migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane.
During metaphase II, when the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Diploid cell) RrXY
Gametes) RY, rY, RX, rX
The alleles of each of the genes randomly migrate to different poles and combine with the allele of the other gene that migrated to the same pole.
Answer:
Eukaryotes have multiple replication forks, histones. Eukaryote have more Deoxyribonucleic acids in their genome compared to prokaryotic cells (e.g bacteria)
Explanation:
Bacteria is an example of prokaryotic cell. The difference between Eukaryotic cells and Prokaryotic cells is that prokaryotic cells are simple in structure, they have no nucleus, no organelles and a small amount of DNA in the form of a single, circular chromosome. While Eukaryotic cells have a well defined nucleus, multiple organelles and more DNA arranged in multiple, linear chromosomes
DNA synthesis is therefore more complex in eukaryotes because eukaryotes have multiple replication forks in which when replication occurs, precautions need to be set in place in order to prevent unwinding of the DNA strand in multiple sites in a single replication cycle. Also, the DNA in eukaryotes is packaged around histones to form chromatin. Before replication can occur, DNA needs to first be unwound around histones.
Eukaryotic DNA polymerase incoperates DNA at a much slower rate (17 nucleotides per second) than prokaryotic polymerase (1000 nucleotides per second). Therefore the eukaryotic cells are equipped with a slower polymerase but numerous replication forks more than just the two that are found in prokaryotic cells in order to effectively replicate the increased amount of DNA.
