The answer is c I think sorry if it is wrong
Answer:
The correct answer is -
1. Archaea are prokaryotic cells. These are one of the two prokaryotic organism domain. the other is eubacteria.
2. Eubacteria cell wall contains peptidoglycan which is composed of sugar and amino acids.
3. Eukaryotic cells have membrane-bound nucleus or organelles. which distinguishes it from prokaryotic cells.
4. All archaea domain organisms found in extreme conditions such as halophiles, extremophiles, and thermophile.
5. The cell wall of the plant is made of cellulose, a polymer of glucose units.
6. Eubacteria are considered to be the first living organism or form found on earth.
7. Fungi cell walls are made up of a chitin cell wall. which is makes it different from eubacteria and plants.
8. Fungi uses absorption to obtain nutrients. Most of the fungi uses haustaurium to absorb nutrients.
9.Fungi are organism that do not fit in other eukaryotic category. Hence they were classified as separate kingdom in 5 kingdom classification.
10.plants are classifies as autotrophs because they make their own food.These autotrophs serve as primary producers.
11.Corals have a symbiotic relationship with algae. Algae provide food for coral through photosynthesis where as coral provide protection to algae.
12.corals are classified as autotrophs due to their relationship with algae.They are mixotrophs generally because they act as autotrophs with association of algae and capture prey by tentacles thus making heterotrophic nutrition.
Reactants. Reactants are the substances that are needed for a chemical reaction to occur. Without reactants there are no products.

Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.
