They’re electromagnetic radiation wavelengths that are visible to most human eyes.
Answer:
Ribosomes
Explanation:
Cellular fractionation consists of centrifugally separating the subcellular structures after cell disruption. Cells can be broken in many ways, the most common technique being a rotating plastic pestle inside a tube. The space between the pylon and the tube wall should be sufficient to break the cells causing minimal damage to the organites. After cell disruption, the resulting paste-like material is centrifuged to separate the organelles. The smallest organelle that can be isolated in this type of process is the ribosomes.
Answer:
B. Stabilizing selection
Explanation:
When natural selection acts against the extreme phenotypes but favors intermediate variants, it is called stabilizing selection. Stabilizing selection is mostly operative in the population s that are well adapted to the prevailing environmental conditions. Individuals with average or intermediate phenotypes are favored by stabilizing selection.
In the given example, the elk population maintains the antler size over generations. Most of the elks have intermediate-sized antlers while only a few have larger or smaller antlers. Since the average antler size (the intermediate phenotype) is favored over the extreme ones (larger or smaller sized antlers), the population is experiencing stabilizing selection.
<span>the darkspots on the photosphere are known as : C. sunspots
this phenomenon happened because reduced surface temperature cause a concentration of magnetic fluc.
The type of electromagnetic radiation that cannot be focused is : A. gamma rays
gamam rays caused the electric fluctuation in the field to be much faster than the electron distribution, making it unable to be focused</span>
