Given what we know, after you’ve removed a loopful of broth culture from the culture tube you should immediately apply a flame to the open end of the test tube.
<h3>Why would this be the next step?</h3>
Once you have removed the loopful of broth culture from the tube, you should apply a flame to the end of the tube, this is of vital importance. The reason for this is to deny any other contaminants from entering or exiting the culture sample.
Therefore, we can confirm that after you’ve removed a loopful of broth culture from the culture tube you should immediately apply a flame to the open end of the test tube.

Biological systems do not contradict the second law of thermodynamics. Even in this case, entropy is still always increasing. Biological systems can only decrease their own entropy by using copious amounts of energy and by increasing entropy in their surrounding environment. Also, unfavorable anabolism reactions are always paired with more favorable reactions, such as the use of ATP in order to make the overall Gibb's free energy of the reaction negative.
<span>Osteoporosis is most likely to be affected by : Phosporus cycle.
basically, our skeleton are the warehouse of two substance, calcium and phosporous. If our skeleton has insufficient amount of these two susbtance, it will weakened its composition and caused the osteoporosis</span>
<span>B.The existence of vestigial structures
</span>
Vestigial structures have been used for long by evolutionists to support the theory of evolution. These organs are believed to have been in use in the past lives but as the species adapts to new forms of life and lifestyle,the vestige organs becomes obsolete,but are not removed by the body. An example of vestige organs in human being are the appendix,tail bone,and mammalian grands in men.

Answer:
Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.
The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense and begins to rise. The cooler and denser air mass from the poles rushes in, through the lower atmosphere, to replace the void of the rising air.
When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.
The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.
