Answer:
A gamma-ray, or gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist, and physicist discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation alpha rays and beta rays in ascending order of penetrating power.
Explanation: hope this helps :)
Answer
Environmental pressures

Answer: Rivers
Explanation: Runoff from cars and other pollutants usually flow off of roads into rivers or streams that usually lead into bigger bodies of water such as oceans.
Answer:
...were due to single genes and followed simple inheritance patterns (dominant/recessive).
Explanation:
The traits Mendel studied were easy to track because the two possible outcomes were distinct and the trait itself was visible and trackable. The fact that they followed simple inheritance patterns helped him when he was determining his ratios for different crosses because complex inheritance would've muddled his data.
