Answer:
- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.
- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:
1. Damaged DNA
2. Increase of cytosolic calcium concentration
Explanation:
Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.

The answer is D. This is referred to as reflex reaction. Reflex is the instantaneous and involuntary reactions to a stimuli. Reflex arc does not pass through the brain so the reaction time is shorter than normal. This is a adaptation to increase survival.
This means that the micrograph was created by an electron microscope
The difference between these three types of rock is in their formation process:
• Igneous rocks are formed by thesolidification of melted rocksm(agma) inside the Earth.
,
• Metamorphic rocks are formed from the other types of rock that suffer changes due to different processes,for examples caused by high preasures or heat.
,
• Sedimentary rocks are formed by the accumulation
