Bacteria will multiply so fast between
41-135 degrees Fahrenheit. Bacteria
can grow rapidly in the TDZ, also known as the Temperature Danger Zone, which
is 41f - 140f. Generally 37 degrees - body temperature. However some,
such as fungi, prefer lower temperatures as they are found on the outside of
the body. Similar some bacteria.
Skin serves as a protective barrier, a way to sense the world, and a layer that keeps nutrients and water inside the body. Four types of cells make up the skin, and they are produced mainly in the epidermis near the basement membrane.
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
Cancer cells reproduce the same way the other cells reproduce. The difference between cancer cells and others is that their reproduction is uncontrollable. They constantly go through the cell cycle and they reproduce. Two ways cell reproductions are meiosis and mitosis. DNA duplicates itself. Cancer is incessantly receiving messages.
Answer:
The power of the lens of an eye adjust or bends the light rays to provide an image on the retina depending on distance of the object.
Explanation:
The lens of an eye and the cornea work together in forming a real image in the retina that houses numerous receptors in the fovea and blind spot of the optic nerve.
Image will be formed in the retina when light rays converging most at the cornea upon entering and exiting the lens.The power of adjusting the eyes focal length is known as accommodation.
