Answer:
Macro-capsule: thickness of 0.2µm or more, visible under light microscope
Microcapsule: thickness less than 0.2µm, visible under Electron microscope
Explanation:
It has several functions: promote bacterial adhesion to surface or interaction with other organisms; act as a permeability barrier, as a defense mechanism against Phagocytosis and/or as a nutrient reserve. Among pathogens, capsule formation often correlates with pathogenicity
correct me if I'm wrong
Answer:
Capsule (also known as K antigen) is a major virulence factor of bacteria, e.g. all of the principal pathogens which cause pneumonia and meningitis, including Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Klebsiella pneumoniae, Escherichia coli, and group B streptococci have polysaccharide capsules on their surface. Nonencapsulated mutants of these organisms are avirulent.
It has several functions: promote bacterial adhesion to surfaces or interaction with other organisms; act as a permeability barrier, as a defense mechanism against phagocytosis and/or as a nutrient reserve. Among pathogens, capsule formation often correlates with pathogenicity.

1) A simplified nitrogen cycle in the ocean is shown here. The movement of nitrogen can impact algae growth, particularly the phytoplankton populations shown here. Large marine mammals, like whales,
move to the surface of the ocean and release nitrogenous wastes in the form of ammonia. Analyze the nitrogen cycle and select the logical explanation on the impact of the phytoplankton populations
A) Phytoplankton populations will increase as nitrogen availability increases at the surface.
B) Phytoplankton populations will decrease because the ammonia is toxic to the phytoplankton,
C) Phytoplankton populations will decrease as nitrogen influx will cause the phytoplankton to be outcompeted by the bacteria.
D) Phytoplankton populations will not increase nor decrease because ammonia is not a usable form of nitrogen for the phytoplankton
The Practice
Answer:A) Phytoplankton populations will increase as nitrogen availability increases at the surface.
Phytoplankton populations will increase as nitrogen availability increases at the surface. So, the correct option is (A).
What is Nitrogen cycle?The nitrogen cycle is defined as the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates in atmospheric, terrestrial and marine ecosystems where nitrogen is transformed through both biological and physical processes.
The steps which are involved in this process:
Nitrogen fixation.Assimilation.Ammonification.Nitrification.Denitrification.Dissimilatory nitrate reduction to ammonium.Anaerobic ammonia oxidation.It is a repeating cycle of processes during which nitrogen moves through both living and non-living things such as the atmosphere, soil, water, plants, animals and bacteria. In order to move to different parts of the cycle, nitrogen must change form. In this cycle , the phytoplankton increases the nitrogen availability.
Thus, Phytoplankton populations will increase as nitrogen availability increases at the surface. So, the correct option is (A).

how are tumor cells different from normal cells?
Answer:
Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells. These cells can invade body parts, such as the breast, liver, lungs and pancreas.
