Answer:
Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.
Explanation:
Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.
Answer:
Actin filament are one subunit type.
Intermediate filament has many subunit types.
Microtubules has two subunit types.
Intermediate filament has diverse cellular role.
Explanation:
Actin filament is a monomeric subunit of two types of filament in cells. The two types of filaments are the microfilaments which is one of the three components of the cytoskeleton and the thin filament which is a part of the contractile apparatus in muscle cells. Actin filaments are made up of identical actin protein arranged in a long spiral chain. Actin filaments play a major role in cytokinesis and in cell movement.
Intermediate filament have a strong and rope-like structure. Intermediate filaments are composed of various proteins, depending on the type of cells they are found. The play a significant role by working in tandem with microtubules to provide strength and support do flagile tubule structures.
Microtubules contains two polypeptide subunits in which the dimers of this subunits string together to form long strands called the protofilament. They are long and cylindrical in structure. They perform a variety of functions which include the determination of cell shape, involvement in cell movement and in the position of organelles in cells.
Answer:
This is the process where certain things like pesticides work their way into water bodies and then move to the food chain to greater concentrations as they are incorporated into meals of aquatic organisms e.g. zooplankton. An example is: small fish that eats plankton that has been tainted with mercury.

Answer:
Thyroxine is a hormone the thyroid gland secretes into the bloodstream. Once in the bloodstream, thyroxine travels to the organs, like the liver and kidneys.
