Walking
Explanation:
A muscle cell usually contracts or expands simultaneously when one is working or doing some activities like running, exercises, house chores e.t.c
Muscles are flexible fibers that are very essential appendages for locomotion in human beings.
For muscle cells to contract, they are pulled together thereby causing tension in the muscle. When they are relaxed, they move away from one another.

Answer: A, C, and E are correct
Explanation:
Sympatric speciation is a random or naturally occurring event whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e no single specie occupy
an area in isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory and practice non-random mating, which favors some genes results in an uneven gene flow or disruption of alleles previously common among the population.
- produce offspring with extra sets of chromosomes known as polyploidy, leading to show genetic variations
Finally, M. graminicola and S passerinii are Sympatric species based on the already given explanation.
Answer: There are 47 chromosomes in each body cell.
