Answer:
B. plasma membrane
Explanation:
Both plants and animals are eukaryotic organisms, it means that their cells contain 1-a nucleus that has linear chromosomes and 2-membrane-bound organelles such as mitochondria and endoplasmic reticulum. Moreover, chloroplasts are organelles found in the cells of plants and algae. On the other hand, bacteria are prokaryotic unicellular organisms that have neither an envelope-enclosed nucleus nor other specialized organelles. Most bacteria contain a genome composed of a single DNA molecule (i.e., one circular chromosome).
Answer:
Ionizing radiation
Explanation:
Ionizing radiation is a method of sterilization that can be used to sterilze material that can not withstand some higher temperature and cannot be exposed to water for sterilization.
It is form of energy that is released when atoms is released to move in the form of electromagnetic waves or particles. such as; X-rays or Gamma rays particles,neutrons, alpha or beta.
It could be dangerous if atoms inliving cells is exposed to it because the cell will be ionized, and it can lead to death of cell , or the mutatation of cell and can lead to cancer. Although not all cells are affected by ionizing radiation.
1)X-Rays, X-rays move in the form of photons energy .
2)Alpha Particles. Alpha particles have less penetration than gamma ray they don't penetrate skin as x-rays
3)Beta Particles, they are particles of electrons which are faster than alpha particles.
Orogeny is a mountain building process while epeirogeny is a content
Two examples of radioisotopes that can be used are carbon-14 to determine the age of fossils. Second, we can use iodine-131 to treat thyroid disease.
