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.
Budding is a form of grafting in which a single bud is used as the scion rather than a section of stem. It is the most commonly used method for fruit tree production in the nursery, but can also be used for topworking plum, cherry, apricots, and peach as well as young apple and pear trees.he cleft graft is used for topworking older established apple and pear trees, either on the trunk of a small tree or on the side branches of a larger tree. It is best adapted to branches 1 to 2 inches in diameter.
