Based on the picture, how did the sunflowers show their competition? Why should they compete?
I choose this as a scientific question because there are numerous sunflowers that occupy the land. Living things try to survive with their environmental conditions. Thus, competition happens among the organisms.
<span>The answer is nerve net.
Jellyfish has a nerve net that surrounds its
whole body. It makes a series of interconnected neurons that form net-like structure. This net surrounds the whole body of the jellyfish. Some jellyfish may have sensory structures, motor nerve net, and diffuse nerve net. Sensory structures receive environment signals and send them through diffuse nerve net to motor nerve net that activates muscle contractions.</span>
Answer:
true
Explanation:
<em><u>Some water pollution is caused from “point sources” that is discrete locations, from which pollutants are discharged, e.g., a pipe, ditch, ship, or factory smokestack. Point sources originate in large and easy to trace facilities, hence are easier to control. In contrast, pollution from “nonpoint” sources is cumulative, arising from multiple inputs over larger areas, such as farms, city streets, and residential neighbourhoods. Hence, such sources are harder to precisely identify, and because of this uncertainty, nonpoint source pollution is harder to control than the point source.</u></em>
Answer: Plasmid.
A plasmid is a small DNA molecule within a bacteria cell that is separated from the chromosomal DNA and can replicate independently. Through Recombinant DNA, we can insert a gene that we want to see replicated in the plasmid, and when the bacteria multiplies, which it does often, we will obtain a lot of copies of interest gene.
