The answer should be 2 because planting trees gives out oxygen and we need oxygen to live
Answer:
Photon radiation
A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).
The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.
Answer: diplontic plant
Explanation:
The mosses belongs to the phylum of non-vascular plants. They produce spores instead of seeds. They do not produce flowers, true roots and wood. They do not posses a vascular system. They exhibit a diplontic life cycle. The diplontic life cycle involves the formation of diploid gametes. In mosses the diplontic life cycle the mosses produces diploid cells and in only one stage they produce haploid cells.
Because water is so good at storing heat energy, it is harder for organisms to experience a change in body temperature in harsher climates.
Answer: 8hrs
Explanation:
G1 phase is the intermediate phase between the end if cell division and the beginning of DNA replication.
Thus to get the duration of the G1 phase = 1/3 × 24hrs = 8hrs
