Taxonomy
The Radio-ulna and digits of most primates and animals represents a homologous structure
An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>
Pseudo vacuoles are not true organelles since they are just air bubbles which do not possess tonoplast and cell sap like real vacuoles. But they do help by increasing buoyancy of cells.
A synovial joint is surrounded by a two layer <em>joint capsule</em> which encloses a fluid filled space called the <em>synovial cavity</em>. The outer layer of this structure consists of <em>dense connective tissue</em> which is continuous with the periosteum of each bone. The outer layer may be reinforced by <em>ligaments</em> which are bundles of collagenous fibers. Some of these bundles are part of the capsule while other are located outside of the capsule. By definition, the structures, such as some ligaments, that are located outside the capsule are called <em>accessory structures</em>. The inner layer of the joint capsule is the <em>synovial membrane</em>, consisting of loose connective tissue. The inner lining of the joint capsule secretes a fluid called <em>synovial fluid</em>. This fluid is viscous, and moistens and lubricates the surfaces within the joint capsule
Answer:
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
