3: Brain regions and their functions. Certain parts of the brain govern specific functions. For example, the cerebellum is involved with coordination; the hippocampus with memory. Nerve cells (neurons) are the basic unit of communication in the brain.
Budding is a type of asexual reproduction. It is most commonly associated with bacteria and yeast, but some animal species reproduce via budding, too. A parent organism creates a bud from its own cells, which then form the basis of the offspring organism and develop into an organism resembling the parent.Animals that reproduce this way are basic organisms, either without reproductive organs or with both male and female reproductive organisms located internally.hey take in oxygen and nutrients through the process of diffusion. To reproduce, flatworms produce self-fertilized eggs and release them. Upon release, these eggs split and go on to grow into entirely new organisms. All types of parasitic flatworm, such as tapeworms, use budding.
Most unicellular organisms, and a few multicellular organisms, use cell division to reproduce, in a process called asexual reproduction. In asexual reproduction, one organism produces one or more new organisms that are identical to itself and that live independently of it.he bud grows until it forms a complete or nearly complete new organism that is genetically identical to the parent. In some budding organisms, buds can form from any part of the body. In other organisms, buds can be produced only by specialized cells in particular parts of the body.
