The correct answer to this question is D.
Answer:
The correct options are:
a) The ability to halt the cell cycle in response to DNA damage.
c) The ability to repair DNA damage.
e) The ability to stimulate cell death processes if the cell is irreparably damaged.
Explanation:
p53 gene has been called 'the guardian of the genome' because its prevents genome mutations which can bear to tumor formation. The main roles of p53 are:
DNA repair (option c): it activates a ribonucleotide reductase which is involved in DNA repair when it is damaged.
Growth arrest (option a): it avoids the cycle cell progression when a damage occur.
Apoptosis (option e): it induces programmed cell death or apoptosis (because every cell must die eventually).
These processes are involved in prevention of tumor formation through activation/inhibition patways which in last instance prevent the replication of cells with a damaged/mutated genome.

Answer:</h2>
The largest source of information on metamorphism relative to plate tectonics is found in converging plates. Metamorphic rocks can be found up to 100 kilometers.
It is evident that igneous rocks are closely related to metamorphic rocks in subduction zones.
non-living factors in an ecosystem are things that are not alive. like so rocks, water, air, soil and sunlight.
Answer:
Las flores de pepino son masculinas o femeninas, y los frutos se desarrollan solo a partir de flores femeninas. Las flores masculinas suministran el polen, que las abejas llevan a las flores femeninas, cuyos ovarios, una vez que las flores son polinizadas, se hinchan.
