[#551] SNARE proteins are found in
Correct Answer

(D) Both B and C

Explanation

Solution: SNARE proteins are found in Golgi bodies as well as Endoplasmic reticulum. A soluble N-ethylmaleimide-sensitive factor activating protein receptors is SNARE. SNAREs are short proteins that are bound to the surface of the vesicle and the membrane, connected by a segment that crosses the membrane or by covalently-attached lipid chains. When the SNARE proteins come together, they form a tight bundle of alpha helices that pull the membranes into proximity.

[#552] The coding strand of DNA has the polarity
Correct Answer

(A) 5' - 3'

Explanation

Solution: The coding strand of DNA has the polarity 5' - 3'. DNA is double-stranded, but only one strand serves as a template for transcription at any given time. The coding strand is the strand used when displaying a DNA sequence. It is presented in the 5' to 3' direction. This template strand is called the noncoding strand. The non-template strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.

[#553] An example of a heterozygous but homogeneous population is
Correct Answer

(C) Hybrid variety

Explanation

Solution: An example of a heterozygous but homogeneous population is the Hybrid variety. A hybrid variety has homogeneous but heterozygous population. Synthetic and composite varieties are developed in cross-pollinated species. Such varieties consist of several homozygotes and heterozygotes and thus constitute a heterogeneous population.

[#554] Light phase of photosynthesis is not affected by
Correct Answer

(C) Temperature

Explanation

Solution: The light phase of photosynthesis is not affected by Temperature. The light-dependent reactions of photosynthesis are not affected by changes in temperature, the light-independent reactions of photosynthesis are dependent on temperature. They are reactions catalyzed by enzymes.

[#555] Endosperm provides nutrients to the embryo as it contains
Correct Answer

(D) All the above

Explanation

Solution: The endosperm provides nutrients to the embryo as it contains Hormones, Vitamins and Enzymes. The endosperm is a tissue produced inside the seeds of most flowering plants following double fertilization. It is triploid in most species, which may be auxin-driven. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.
