Im not for sure but i think its D if that helps any
Answer:
C.In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.
Explanation:
C. In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.
This statement not true for a following reasons.
Firstly, creatine phosphate directly phosphorylates ATP instead of providing any support for aerobic pathways.
Secondly, creatine phosphate stores are used up in about 15 seconds only. Thirdly, a cell does not need oxygen deficit for creatine phosphate to be activated, it just needs to be short on ATP.
Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".
<u>Answer:</u> Option B
<u>Explanation:</u>
Global circulation is defined as the global connection of winds, through which the requisite heat transport from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.
The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.
