Answer: Option C. -> virus
Mumps is a contagious disease that is caused by a virus. It typically starts with a few days of fever, headache, muscle aches, tiredness, and loss of appetite. Then most people will have swelling of their salivary glands.

Answer: Option B. -> 47
Number of chromosomes in down's syndrome is 47.
Number of chromosomes in down's syndrome is 47.
Answer: Option B. -> active transport
Active transport, this is the only transport method that can move species against their concentration gradient (from low to high concentration). Facilitated diffusion only moves species down their concentration gradient from high to low concentration.

Answer: Option C. -> amino acids
We know that, proteins are polymers of amino acids. So, plants are also used to synthesise protein from amino acids. Hence, plants synthesis protein from amino acids in the presence of ATP by specific synthetases.

Answer: Option A. -> Leaf and other chloroplast bearing parts
In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll.

Answer: Option A. -> free nitrogen
The plant cells absorb nitrates from the soil and convert them into ammonia which ultimately reduced to ammonium ions (NH4+). These ammonium ions are then combined with organic compounds to form amino acids such as glutamine i.e., free nitrogen. This process of conversion is known as nitrogen fixation.
