Answer:
Yes
Explanation:
All mutations will be passed onto new cells through DNA replication, and all RNA made from that DNA will also have the mutation. If the mutation occurs in sperm or egg cells, those mutations will also be passed on to the organism's offspring.
<span>Well water draws from the sources of water beneath the Earth's surface. This type of water supply is known as "groundwater."
</span><span>Groundwater includes water that flows naturally from below the Earth's surface to the surface by way of springs. Some springs run entirely underground and do not break through the surface. Groundwater also includes water that is contained in a variety of porous materials that lie beneath the Earth's surface, such as silt, gravel, clay and sand. Water collects below ground in these porous materials into structures called aquifers. Generally speaking, well water collects into the well from these water-bearing structures. Wells are situated in the Earth to access the aquifer at a depth well below the surface.</span>
Explanation:
Gram staining is a widely used technique designed to distinguish between the bacteria on the basis of the composition of the cell wall of the bacteria.
The basis of differentiation is the color of the bacteria they attain after staining technique is performed that is gram-positive bacteria remain deep blue in color while gram-negative bacteria appear pinkish-red in color.
If the culture of the bacteria on which the test to be performed is of more age that is more than 24 hours of age then the bacteria cells lose their ability to retain the stain mainly the gram-positive bacteria. Also, the culture gets damaged after 24 hours.
Thus, fresh cultures are used for staining.
