Answer:
Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition.
Explanation:
They would've the same size, be in the same location and contain the same DNA.
A twitch is defined as a single, brief contraction period and then relaxation period of a skeletal muscle in response to a single stimulation. Contraction period involves receptive power strokes that pull the thin filaments past the thick filaments shortening sacromeres and muscle tension increases as the sacromeres shorten. Relaxation period begins with or release of cross bridges resulting from the return of Ca2+ back to sarcoplasmic reticulum. The strength of skeletal muscle contractions can be broadly separated into twitch, summation, and tetanus. A twitch is a single contraction and relaxation cycle produced by an action potential within the muscle fiber itself.
ATP stand for adenosine triphosphate. It consists of the nitrogenous base adenine and is linked to a sugar molecule. It is necessary for human life because it gives the body energy
1st question-B) chemoautotrophs
Reason: light can't penetrate into hostile habitats like volcanic vents deep in the ocean. The prokaryotic cells there are called chemoautotrophs and produce food through chemosynthesis. A process where chemical energy is used to produce carbohydrates instead of light(photosynthesis)
2nd question- Answer is A
Reason: super bugs are strain of bacteria that don't respond to antibiotics. You can prevent this by using antibiotics only when directed by a physician and only when needed.
