Answer: CFU/mL = 14200 CFU/mL
Explanation:
Microorganisms are very small and difficult to count directly. Instead, a laboratory technique is used to count CFUs (Colony Formation Units). This involves making dilutions of a microbial suspension and spreading it on thin layers of agar containing nutrients for growth in Petri dishes also called agar plates. After incubation under ideal conditions, some plates are completely covered with microbial growth; some have little or no growth; and some are covered with individual isolated "spots", which are microbial colonies. Since a colony may consist of a single organism or a group of microbes, the dots represent a CFU.
To calculate the viable count of the stock culture, you have to count the number of colonies, multiply by the dilution and the result will be the plate count in CFU.
So, the equation is:
CFU/mL = Number of colonies / (Volume trasferred to plate x dilution blank)
100 microliters = 0.1 mililiter
1/10 = 0.1 (dilution factor)
Replacing the information from the question:
CFU/mL = 142 / (0.1 mL x 0.1)
CFU/mL = 14200 CFU/mL

Methane gas is more potent( roughly by 30 times), as a greenhouse gas than carbon dioxide.
Explanation:
Greenhouse gases in the atmosphere trap infrared radiation (responsible for the transfer of heat) that reflects off of the earth's surface instead of allowing most of this radiation to escape to space. This causes heat to build up in the atmosphere. The more the greenhouse molecules are in the atmosphere the higher this effect is. Global warming is subsequently blamed for climate change around the world.

Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.
