Answer:
The correct answer is: E) both B and C.
Explanation:
- Bacteria and Archaea forms two distinct and different Domains in the Taxonomic classification system.
- Nuclear envelope that surrounds and protects the genetic material by forming the Nucleus is absent in both Archaea and Bacteria. Both of them possess a region called the Nucleoid where their genetic material is located.
- Plasma membrane that surrounds the cell and maintains integrity of the cell structure is present in both Bacteria and Archaea. Although the composition of lipid in the plasma membrane is different in each.
- However, they vary in their cell wall composition. The cell wall of the bacteria is rich in a compound called peptidoglycan while the cell wall of archaea lacks peptidoglycan and is rich in polysaccharides and glycoproteins.

The correct answer is: about 99%.
The main difference between two random people’s genetic make-up issingle base pair differences, or polymorphisms (SNPs). There are about one SNP per 1000 bases. Since the human genome is about 3 Gbp long, about 3 million SNPs among two random people is present. SNPs may occur within coding sequences of genes, non-coding regions of genes, or in the intergenic regions.
Answer:
NO
Explanation:
The animal cell and plant cell are both eukaryotic cells. Eukaryotic cells are the type of cells that contains membrane-bound organelles, such as the nucleus, mitochondria, Golgi apparatus and a cytoskeleton.
The cytoskeleton, which is composed of microfilaments, internal filaments, and microtubules, <u>is present in both the animal and plant cells.</u>
However, some of the organelles that are not present in both the animal cell and the plant cell are centrosome and lysosomes.
<u>The </u><u>lysosome</u><u> is present only in the animal cell.</u>
