human reproduction

Question 1

(d) asexual reproduction

Answer 1

process resulting in the production of genetically identical offspring from one parent

Question 2

can asexual reproduction proceed without the fusion of egg and sperm?

Answer 2

yes

Question 3

types of asexual reproduction

Answer 3

budding, fission, fragmentation/regeneration

Question 4

(d) budding

Answer 4

produces offspring by the outgrowth and eventual splitting off of a new individual from the parent

Question 5

(d) fission

Answer 5

parent that separates into two or more offspring of about equal size

Question 6

(d) fragmentation and regeneration

Answer 6

fragmentation is the breaking of a parent body into several pieces and regeneration is the regrowth of lost body parts

Question 7

advantages of asexual reproduction

Answer 7

eliminates the need to find a mate, allows a population to perpetuate itself if its individual members are isolated from one another, permits organisms to multiply quickly without spending time or energy-producing sperm and eggs,

Question 8

disadvantages of asexual reproduction

Answer 8

genetically identical, limits a population’s chances if surviving periods of drastic environmental change (natural selection)

Question 9

(d) sexual reproduction

Answer 9

process involving the fusion of two haploid sex cells (gametes) to form a diploid zygote (fertilised egg), production of genetically dissimilar offspring
