B. Organelles.
Prokaryotes (Bacteria etc.) usually have a cell wall, cell membrane, nucleoid, ribosome and a plasmid; unlike eukaryotes (Human cells) which have golgi apparatuses, Mitochondrias..etc
Hope this helps
They replace the lost ions by active uptake through active transport
of ions from the surrounding waters. This is exhibited in freshwater fishes that
actively take in these ions through the gills. Most of the ions involved in osmoregulation in freshwater are those of Na+ and Cl-.
the insertion on removal of mutations are dangerous in nature. the process is basically just one large gamble to see what it does. and even though we have a decent understanding of the genomes of many animals and plants, we still dont know everything. so if we tamper with certain genes we may cause a evolution or we might kill the subject and the potential for it to procreate.
Answer:
A higher frequency causes a shorter wavelength and higher energy.
A shorter frequency causes a greater wavelength and low energy.
Explanation:
Frequency is the number of waves that move at a period of time. It is measured by counting the number of crest point.
Wavelength is the distance between waves. A wave with higher frequency have crest that a very close and therefore the distance between them or wavelength is short compare to a wave with low frequency that the distance are farther apart and they have long wavelength. Therefore to generate high frequency of wave , more energy is required to do this .
B
The other problems are not as easily solved; whereas, data collection over long periods of time is possible and was already done in the past, eg temperature and weather patterns. Therefore, this is the easiest limitation to overcome.
