Answer:
the Soviet Union and U.S.A, Gemini VI, commanded by Mercury astronaut Wally Schirra and piloted by Tom Stafford, was supposed to have orbited on October 25, to rendezvous and dock with an Agena target vehicle. But the unpiloted Agena spacecraft blew up during launch that morning, stranding the crew waiting in their vehicle on Launch Complex 19.
Almost all of the organisms in the PLANTAE kingdom are photosynthetic.
The best answer is; False
Fresh water found in soil and rock layers below Earth’s surface is not called deep water. It is known as ground water. Groundwater is the water that exists below the earth's surface in the cracks and spaces in soil, rock and sand. Groundwater flows to the earth surface naturally and discharges to water bodies such as rivers, lakes and wetlands. Groundwater is usually extracted for municipal, industrial and agricultural uses by extraction wells.
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.
