Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
Answer:
a primitive mammal that lays large yolky eggs and has a common opening for the urogenital and digestive systems. Monotremes are now restricted to Australia and New Guinea, and comprise the platypus and the echidnas.
Explanation:
The resolving power of the earliest electron microscopes was at least ten times higher than that of the light microscopes, mainly because the wavelength of electrons is much shorter than the wavelength of light.
The electron microscope uses a beam of accelerated electrons to magnify the object whereas the light microscope uses visible light for this purpose. Unlike the light microscope, the electron microscope uses electromagnets as lenses.
The magnification of the electron microscope is much higher as compared to the light microscope and it produces high-resolution images. However, the Specimen preparation of an electron microscope takes several days while the Specimen preparation of the light microscope takes only a few minutes.

The correct option is THE ELECTRON IN THE OUTERMOST ELECTRON SHELL.
Different levels of energy exist in the atom of an element and these levels are filled with electrons. The electrons in the innermost shell has the lowest energy level while the electrons in the outermost shell has the highest energy level. For an electron to increase its energy level, it has to move to an higher shell; and to decrease its energy level it has to move to a lower shell.
Let us consider the centripetal force equation,
centripetal force F = mv² / r
f= force
v= velocity
m= mass
r= radius.
in all the factors only velocity has the power of 2. so when you double the velocity then it will become square of that.
if v= 2v , F = m4v² / r
so velocity is doubled it would produce the greatest change in the centripetal force.
