Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of asexual reproduction involves a body part regrowing and forming a new organism?
A
fision
B
budding
C
regeneration
D
sexual reproduction
Explanation: 

Detailed explanation-1: -Budding. Budding is a form of asexual reproduction that results from the outgrowth of a part of a cell or body region leading to a separation from the original organism into two individuals. Budding occurs commonly in some invertebrate animals such as corals and hydras.

Detailed explanation-2: -Budding. In budding, organisms reproduce by having new individuals split off from existing ones, which results in genetically identical parent and daughter organisms. The bud may stay attached or break free from the parent.

Detailed explanation-3: -Regeneration is a type of asexual reproduction in which the organism is capable of regrowing certain body parts. Regeneration occurs via mitosis. Lizards can regenerate their tails, star fish can regenerate their arms while humans have the ability to regenerate their liver to a certain extent.

Detailed explanation-4: -budding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas.

Detailed explanation-5: -Parthenogenesis is a form of asexual reproduction where growth and development of embryos occur without fertilization. Parthenogenesis occurs naturally in aphids, rotifers, nematodes and some other invertebrates, as well as in many plants and certain lizards, such as the Komodo dragon.
