What Are Three Embryonic Tissue Layers Of Animals?
The three embryonic tissue layers of animals are ectoderm, mesoderm, and endoderm. These layers give rise to different specialized tissues and organs in the developing organism during the process of gastrulation. Ectoderm develops into structures like the skin and nervous system, mesoderm gives rise to muscles and bones, and endoderm forms the lining of the gut and associated organs.
What are the advantages and disadvantages of both asexual and sexual reproduction?
Asexual reproduction does not lead to genetic variations while sexual reproduction leads to genetic variations. In asexual reproduction there is no limitation/restrictions for gametes to be fertilized.In sexual reproduction if either of the gametes do not function/not present then the possibility of reproduction becomes nil.Asexual reproduction gives rise to multiple daughter cells from mother cells while sexual reproduction normally gives rise to only two daughter cells.

What are the major divisions of a frog's brain?
A frog's brain consists of three main parts: the forebrain, midbrain, and hindbrain. The forebrain is responsible for processing sensory information and controlling behavior. The midbrain is involved in coordinating visual and auditory reflexes. The hindbrain controls basic functions like breathing and motor coordination.
