Answer:
nuclei, mitochondria and chloroplasts
Explanation:
A protein purification is a series of processes that allow the isolation of a single type of protein from a complex mixture. Protein purification is vital for the characterization of the function, structure interactions of the protein of interest, for example an enzyme a cell receptor or an antibody. The initial material is generally a biological tissue or a microbial culture. There are several steps in the purification process; it can release the protein from the matrix that confines it, separate the protein and non-protein parts of the mixture, and finally separate the desired protein from all the others. This last step may be the most laborious aspect of protein purification.
Techniques used
Homogenization
Cell fractionation
Reversible denaturation with ammonium sulfate
Chromatography
Electrophoresis
Dialysis
Ultraviolet-visible spectroscopy
Enzymatic assay
Answer:
Deep zone, surface zone and transition zone.
Explanation:
Open sea zone is the area of the coastal areas above the sea bed and cover the continental shelf where large Marine organism are present and there is enough sunlight algae organism use to photosynthesize and produce food for the Marine organisms by converting carbondioxide and water into carbohydrates.
The zone stretches from the surface , to the middle and depth of 200 m.
The surface zone is the area where light penetrates most , the transition stretches from the surface zone downward, in this zone light penetrates bit not as much as surface zone and in the deep zone, it stretches from the transition zone downward to a depth of 200 meters and don't have enough light penetration compare to surface and transition.

Explanation:
The best protection from Haemophilus influenza that causes infant meningitis is administration of conjugate vaccines.
Vaccines are injections administered into body to provide protection. They are based on the principle that prior introduction to weakened or killed from a microorganisms produced natural immunity against it which is remembered by the body by memory cells.
The conjugate vaccines are combination of weak and strong antigens which results in stronger immunity against weak antigens. The conjugate vaccine of Haemophilus influenza comprises polysaccharide of the microorganism. Strong antigen are also known as carrier proteins and in this case are either of tetanus, diptheria toxoid or its mutant toxin of diptheria.
