The Nucleus contains most of the genetic information for making proteins
The ribosome is the place where the polypeptide strand and the mRNA meet in order to create a protein
Nucleolus has a role in the biogenesis of the ribosomes
RER -intracelular transport and protein making because of the attached ribosomes
SER-intracelular transport,lipid synthesis and it is the place where the glicogen is metabolized
Golgi Apparatus has a secretive role
Lysosomes contain 40+ hydrolytic enzimes that help with intracelular digestion
Cilia and flagella both help with the moving of the cell
Extracellular matrix keeps the cells together
The Mitochondria sythesizes ATP in a process caled oxidative phosphorylation of organic substances
The answers are solar for the first one, and chemical for the second one
A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.
Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.
Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).
<span>Sumerians built walls using the natural resource they were surrounded with, which was namely clay. They used this clay to create fired mud-bricks, as there was not any other building stone available at the time. However, the clay mud-bricks proved to be a solid structure for town fortification.</span>
