<h2>Answer is option "1 B & 2 C"</h2>
Explanation:
- Evolution genetics is a field of science, which includes the study of genetic variations that lead to evolutionary changes in organisms
- As some bacteria had changed their DNA that led to the development of antibiotic resistance in them
- Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
- Hence, the right answer is option 1 B and 2 C " evolution Genetics & less bacteria becoming resistant to the specific antibiotics"

Answer: SKELETAL MUSCLE
Explanation:
Skeletal muscles is a type of muscle tissue that forms those muscles that move the bones of the skeleton,straited because straitations (strips) can be seen on microscopic examination and involuntary as it is under conscious control.
Although most skeletal muscles move bones,they also accomodate a degree of voluntary control in breathing.
A lot of movements can be finely coordinated.example; writing but may also be controlled subconsciously, maintaining an upright position does not normally require thoughts unless a new locomotor skill is being learned example skating or cycling and the diaphram maintains breathing while asleep.
The fibre (cells) of the skeletal muscle are cylindrical,contain several nuclei and can be up to 35cm long.
Skeletal muscle contraction is stimulated by motor nerve impulses originating in the brain or spinal cord and ending in the neuromuscular junction.
The contraction of a whole skeletal muscle occurs because of coordinated contraction of it's individual fibres.
