A compound microscope has multiple lenses: the objective lens (typically 4x, 10x, 40x or 100x) is compounded (multiplied) by the eyepiece lens (typically 10x) to obtain a high magnification of 40x, 100x, 400x and 1000x. Higher magnification is achieved by using two lenses rather than just a single magnifying lens.
It could be c. But the answer is B
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.
Explanation:
Answer:
The amount of atmospheric oxygen is more than the amount of dissolved atmospheric oxygen in water.
Explanation:
The oxygen which is present in the atmosphere is much higher than the oxygen which is present inside the water. About 21 percent of oxygen is present in the atmosphere while only 1 percent of atmospheric oxygen is dissolved in the water. Oxygen is higher in atmosphere because this oxygen is used during respiration of organisms. If concentration of dissolved oxygen is very high, the marine animals die.
<u>Answer:</u>
<em>The biological macro molecule protein can serve as a precursor to the production of cyanide.
</em>
<u>Explanation:</u>
<em>Cyanides are chemical compounds that contain the cyanide group(C≡N). </em>Based on the elements attached to the cyanide group cyanides can be classified into organic and inorganic cyanides.
<em>In inorganic cyanides the cyanide group is present as 
ion which makes them toxic. In organic cyanides group is not present and thus they are less toxic. </em>
Since nitrogen is the essential component in a cyanide, a biomolecule containing nitrogen will best act as the precursor to cyanide formation.
<em>The biomolecule protein is a long chain polymer of amino acids that contain nitrogen group. Thus proteins can act as precursor to cyanide formation.
