Ans. Option (a).

Genetic engineering involves intentional modification of the characteristics of a target organism by the manipulation of its DNA or genetic material.

It includes five steps: isolation of target gene; formation of recombinant DNA molecule by joining target gene and vector molecule; insertion of recombinant DNA (vector and target DNA) to host cell; production of many copies of recombinant DNA molecule in host cell; separation and purification of target gene product from host body.  

Hence, according to given diagram, step 2 describes cutting of target DNA and vector molecule to get desired fragments, which are then ligated with the ligase enzyme to make a recombinant DNA.

Thus, the correct answer is option (a).

Answer:

From factory emissions to carbon dioxide in the atmosphere (C)

The process occurring can be called Combustion. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because the carbon in organic matter is oxidized to form CO2.

from dead organisms to fossils and fossil fuels (E)

The process explained in the question can be stated as Fossilisation. In this process, dead remains of plants and animals are transformed into fossils under pressure. The organic matter is preserved according to the shape of the organism.

from factory emissions to carbon dioxide in the atmosphere (C) & from carbon dioxide in the atmosphere to photosynthesis (B)

Two reactions represent the conversation of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure

HELP! NOW!
uranmaximum [27]

Answer:

Option-D

Explanation:

Cellular respiration and photosynthesis are the two main physiological process which drives the life on Earth. Photosynthesis process leads to the synthesis of Glucose whereas Cellular respiration breakdown the Glucose molecule to form ATP molecules.

In plants, the photosynthesis process occurs in green leaves whereas cellular respiration occurs in every cell of the plant inside the mitochondria.

In the given question, the graph shows:

1. The absorption of oxygen till 6 am which is required during cellular respiration.  

2. After 6 am, the level of oxygen production becomes more than oxygen absorption till 6 pm.

3. After 6 pm, no sunlight is available therefore photosynthesis does not occur. After this, the rate of cellular respiration increases that is oxygen is taken in.

Thus, Option-D is correct.
