Please help me with this question! A level Biology. Apoptosis lysosomes :)

Bax protein will attach itself to the cell membrane

It will then be released into the ICF

This will cause the mitochondria to release cytochrome c which will act on APAF 1 to form apoptosome.

Apoptosome will then activate Caspase 9 which will then activate caspase 3 and 7.

Caspase 7 will cause release of hydrologic enzymes which will then digest cellular organelles resulting in cell death

answer; a muscle cell, another neuron and a of the above

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
