Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
Answer: Either of the two identical cells that form when a cell divides.
Explanation:
Answer:
it is the process by which carbon dioxide is removed from the atmosphere, is achieved through various chemical and biological processes
The original sample must be refilled and the most probable number (MPN) approach must be used if each dilution of the sample yields too few plates to count.
What is the most probable number(MPN) method?
The most probable number (MPN), a statistical technique based on the idea of extinction dilution, is used to calculate the number of bacteria that are likely to be present in a sample. It is frequently used to estimate the number of bacteria in food and water. However, the technique can only count living creatures. According to Food and Drug Agency (FDA) guidelines, which state that the maximum allowable limit in seafood is 10,000 cells per gram, it is imperative to count <em>V. parahaemolyticus </em>from seafood.
Why is the MPN technique crucial?
When samples include particulate matter that obstructs plate count enumeration techniques, MPN(most probable number) tests are particularly helpful. In order to determine if the water is safe to drink in terms of the number of bacteria present, MPN is most frequently used to assess the quality of water.

At the base of the brain is hypothalamus which received sensory signals from neurons and transmit it to pituitary gland. This gland releases hormones which play an essential role in controlling homeostasis. It often releases hormones of its own which then signal to pituitary gland. Hypothalamus is part of the limbic system
