Explanation:

Winds are caused by low and high pressure zones, mainly due to temperature differences of atmospheric air in different regions. Air moves from high to low-pressure zones causing winds.

Local winds, as the name suggests, are winds due to regional temperature differences. An example is sea breeze caused by temperature differences over land and sea in the region.

Global winds, on the other hand, are caused by large pressure systems across the planet. These are mainly caused by differences in how the sunlight ‘hits’ the planet at different latitudes – due to earth’s spherical nature- causing differential heating of the earth. These winds travel great distances causing trade winds.

Proteus vulgaris has a doubling time of roughly 28 minutes. If an initial population of 500 cells is allowed to grow for 6 hours

romanna [79]

Answer: The final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

Explanation:

We are given:

Proteus vulgaris divides and doubles every 28 minutes

Total time given = 6 hours = 360 min (Conversion factor: 1 hr = 60 min)

Number of times Proteus vulgaris doubles in 6 hours = $\frac{360min}{28min}=12.857times$

Calculating the number of bacteria after 6 hours under ideal conditions:

We are given:

Initial population = 500 cells

Number of times it doubles = 12.857 times

Final Proteus vulgaris population = $500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells$

Hence, the final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

Natural selection is based on the idea that as an environment changes, an individual’s genetic makeup will change suddenly to su

erastova [34]

yes it is right because if we take example of viruses and germs .. new germs and viruses are much modified as compared to old ages because they adopted the ways they can escape from the immunity.. they have an adoption to transmit their DNA material ,also they can take protein coat of host because of which host's immunity cells cannot recognize germs as foriegn particle..and in this way germs and viruses remain for a long time in body due to the adoptations according to age and environment..
