Asexual reproduction
Sexual reproduction
Explanation:
In asexual reproduction the offspring are genetically identical to the parents. Asexual reproduction include binary fission, fragmentation and vegetative propagation.
It involves direct inheritance of the genetic copy of the parent without any alteration. The parent gives rise to the offspring without any intermediary process.
In binary fission, the parent simply divides into two to form a new ones.
For sexual reproduction, there is fusion of gametes which carries genetic materials contributed by both parents. The offspring is an offshoot of the genetic combination of the traits of two parents.
Therefore, genetically, offspring produced by sexual reproduction have a distinct copy of the genotypes they posses. They are different from those of the parents.

Answer:
Explanation:
Given that d = 0.11cm = 0.0011m, l = 2.2m, extension = 1.24cm = 0.0124m, mass = 34kg
force = 34 x 9.81 = 333.54N, Area = Pi x d²/4 = 3.142 x 0.0011^2/4 = 9.505x10^-7m²
Calculate the stress = Force/Area = 333.54N / 9.505x10^-7m²
= 350926661.4N/m²
calculate the strain = extension/original length
= 0.0124 / 2.2 = 0.00563
Young modulus of elasticity = Stress/Strain = 350926661.4N/m² / 0.00563
= 6.2332 x 10^10Pa
