Answer:
Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.
Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.
Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules.
Chemoautotrophs are usually bacteria that live in ecosystems where sunlight is unavailable.
Heterotrophs cannot synthesize their own energy, but must obtain it from autotrophs or other heterotrophs; they act as consumers in food webs.
Hope this helps you.
Ans: The Piedmontese MSTN missense mutation G938A is translated to C313Y myostatin protein. This mutation alters MSTN function as a negative regulator of muscle growth, thereby inducing muscle hypertrophy. MiRNAs could play a role in skeletal muscle hypertrophy modulation by down-regulating gene expression.
