The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.
The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

Answer - A
Semi-conservative model of replication involves the replication of DNA in all the familiar cells in such a way that each newly synthesized daughter cell contains a double helix with one new strand and one old strand.
Answer:
The correct answer is - Ψ = ΨS + ΨP.
Explanation:
The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).
Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.
Ψ = ΨS + ΨP.
Answer:
because

It is an Incomplete question and the complete question is
All healthy, highly productive ecosystems provide which of these essential ecosystem services that involve gases in the atmosphere?
A. increasing carbon dioxide levels in the atmosphere by the action of plants and animals.
B. removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.
C. removing water vapor from the atmosphere and using it to support plant growth.
D. removing methane from atmosphere and storing it's carbon and hydrogen in the tissues of organisms.
Answer:
The answer is removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.
Explanation:
The water and carbon dioxide are byproducts and in which the photosynthesis removes CO2 from the atmosphere and replaces it with O2. In case of respiration it takes O2 from the atmosphere and places it with CO2.
To remove the CO2 it is directly put out of the air and burried it under ground saline aquifers this process is known as carbon capture and sequestration.
Sequestration is a process in which CO2 is removed from atmosphere and stored in the soil carbon pool. This process is mainly done through photosynthesis.
