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:
decline: decrease
Explanation:
Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.
On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.
Options: A. contralateral
B. ipsilateral
C. both
Answer:B. ipsilateral
Explanation:The ciliospinal reflex which is also known bas pupillary-skin reflex is usually made uo of the dilation of the ipsilateral pupil this dilation is in response to pain applied to the neck, face, and upper trunk.
If you stimulate the left side of the subject, the response will be only in the ipsilateral which means the stimulation will be felt in the same side of the subject which in this case is the Left side if the subject.
Answer:
The correct answer is vertebral column and cranium
Explanation:
Vertebrates are the animals that are characterized by having backbone or vertebral column and apart from the vertebral column they also have a bony skull. Skull and vertebral column protect the brain and spinal cord in vertebrates.
Vertebrata is a subphylum under phylum Chordata and clade Craniata so vertebrates have both cranium and vertebral column. In vertebrates, notochord is present in the embryonic stage and is replaced by vertebral column in adults.
Animals that comes under the Vertebrata are fishes, mammals, reptiles, amphibians, and birds. So the correct answer is B and C.
