[#531] Heterodera is a
Correct Answer

(B) Sedentary endoparasite

Explanation

Solution: Heterodera is a Sedentary endoparasite. Heterodera is a genus of nematodes in the family of Heteroderidae. The genus is unique among nematode genera because of the ability of the female to transform into a tough, brown, cyst that protects the eggs which have been formed within her body. The cyst nematodes (Heterodera and Globodera) and root-knot nematodes (Meloidogyne) are sedentary endoparasites within a broad group of free-living and parasitic worms.

[#532] ATP formation during photosynthesis is
Correct Answer

(B) Photophosphorylation

Explanation

Solution: ATP formation during photosynthesis is Photophosphorylation. Photophosphorylation is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. This involves the splitting of the water molecule into oxygen and hydrogen protons (H + ), a process known as photolysis. All organisms produce a phosphate compound, ATP, which is the universal energy currency of life. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by the flow of electrons through an electron transport chain.

[#533] To apply NPK, an NP complex has to be supplemented with
Correct Answer

(B) Potash

Explanation

Solution: To apply NPK, an NP complex has to be supplemented with Potash. NPK (10 : 26 : 26) is a complex fertilizer that contains all three major nutrients 10% Nitrogen, 26% Phosphorous, and 26% Potash which are easily and quickly available to plants. Contain Phosphorous and Potassium in a 1 : 1 ratio. Fertilizers are labeled N, P, or K to indicate their nutrient content in terms of nitrogen (N), phosphorus (P), and potassium (K). All three are important for plant growth.

[#534] Sucidal germination take place In
Correct Answer

(B) Striga

Explanation

Solution: Suicidal germination takes place In Striga. Striga seedbank depletion can be achieved by suicidal germination, a strategy where the Striga seeds are stimulated to germinate in absence of a true-host plant. In suicidal germination, parasitic weeds are germinated without a suitable host. In this way, before crop cultivation, weeds are died off. Infestation by the parasitic plant Striga hermonthica is a severe threat to food security in sub-Saharan Africa, impacting the production of the major staple crops pearl millet and sorghum, equating to 7 - 10 billion $ losses.

[#535] Besides water and light which is more essential as a raw material for food formation
Correct Answer

(A) CO 2

Explanation

Solution: Besides water and light which is more essential as a raw material for food formation CO 2 . Photosynthesis is a process used by plants and other organisms for the synthesis of food. This process converts light energy into chemical energy that, through cellular respiration. Carbon dioxide is converted into sugars in a process called carbon fixation, photosynthesis captures energy from sunlight to convert carbon dioxide into carbohydrates.
