Answer:
True however some are unicellular.
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds. Their paths typically have a meandering shape.
Because polystyrene has certain thermal properties that can be used in order to store things and maintain their temperature.
When you store ice cubes in polystyrene containers they won't melt and they'll keep cold because the cold they'll generate in the container wont escape, and the heat from outside wont come in.

Polystyrene containers are used to store ice cubes because they are good insulators, which helps to preserve the coldness of the ice. These containers are also lightweight and cost-effective, which makes them practical for storage and transportation.
Polystyrene containers are used to store ice cubes due to their excellent insulating properties. Polystyrene foam is a very poor conductor but a good insulator because it traps many small pockets of air, leveraging air's poor thermal conductivity. This material helps maintain the low temperature of the ice, slowing the melting process.
Additionally, polystyrene containers are lightweight and affordable, making them practical for storing and transporting ice. They also won't shatter or break like a glass or metal container if dropped.

Spontaneous generation is a concept of the origin of life that can be traced back to the theories of Greek philosophers Aristotle and Plato and persisted through the Enlightenment Period. While some Enlightenment Period scientists experimented to show that life could arise even under controlled conditions, their methods were not sanitary and microbial contamination of the containers used gave dubious results. it was Louis Pasteur who is generally credited with refuting the idea due to his more advanced and precise control of starting conditions that revealed that no life arose from non-life. This strongly established that life cannot arise from non-life.
Today, we have similar superstition by some naturalists who posit that natural processes are capable of producing living entities, whether it is SETI searching for extraterrestrials, NASA astrobiologists searching for aliens and panspermia, or other life enthusiasts similarly inclined.
Currently, the term abiogenesis is used by naturalists to detail the emergence of life from non-life,and has failed miserably to do so. It is very similar to the spontaneous generation idea that was disproven and lost favor in the 1800's. The current understanding strongly favors abiogenesis because it ideologically fits the belief system that all reality is the result of natural processes and forces, but there is not evidence of its validity, not even at the simplest biochemical levels.
a. Genetic diversity occurs in sexual reproduction.
b. Asexually reproducing organisms can repair their own DNA.
c. There are no special reproductive cells in asexual reproduction.
d. A gametophyte produces haploid cells in the alternation of generations from sexual reproduction.
