Question 1. A. Genetic engineering

Answer:

1. The correct answer would be genetic engineering.

With the help of genetic engineering the breeder would select, isolate, and transfer the gene (responsible for vitamin production) from the carrot plant cell to the potato plant cell.

It is then followed by cell and tissue culture to grow the plant with the desirable character. Lastly, plant breeding is done to yield the transgenic line.

2. The correct answer would be hybridization.

Inbreeding refers to the breeding of closely related animals or plants over many generations.

In contrast, hybridization is the practice of breeding in which organisms of different varieties or species are cross-breed to produce a hybrid breed or variety. It helps in transferring a desired character from one variety to the other.

Prokaryotic cells cell walls contain peptidoglycan sensitive to traditional antibacterial antibiotic. True or False
kherson [118]

Answer:

True

Explanation:

Prokaryotic cell or bacterial cell contain cell wall which is made up of peptidoglycan and traditional antibacterial antibiotics were able to interfere with the cell wall synthesis and cause the destruction of bacterial cells.

For example, one of the most traditional antibiotic is penicillin which inhibit the synthesis of bacterial cell wall by blocking transpeptidation reaction. As it inhibits new cell wall formation it results in the formation of holes in the cell wall.  

These holes in the cell allow movement molecules inside the cell and cause osmotic cell lysis. Therefore the statement is true.

What weight of Tris-HCL (MW=121) is required to prepare 2L of a 15% w/v solution?
podryga [215]

Explanation:

Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.

Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.

                 \frac{15 g}{100 ml} \times 2000 ml

                  = 300 g

Thus, we can conclude that weight of Tris-HCL required is 300 g.
