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:
D. A dairy cow produces milk over several years
Explanation:
A dairy cow is reared mainly for milk production and the cattle normally produces lots of milk as long as it’s well fed. This usually goes on for several years and provides income throughout that period and can then be used for beef purpose later on .
The beef cattle is usually slaughtered and the beef used immediately and has no long term use.
This is why dairy cow brings in more income than a beef cow.
3 is the answer, as 1 is depicting evaporation, 2 is forming of cloud, and 3 is precipitation
This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
