Answer:
Adaption is a gradual process of change or modifications of animal body either physically, structurally or behavioral changes in order to thrive and adjust better in the changing environment for survival.
Explanation:
Adaptation could takes by exhibiting a sort of mimicry to the habitat in which the animal thrive. Also it could takes place by the process of structural changes that blends them well with the environment. Classical Example is the adaptation by Polar bear. In the coolest arctic region, polar bear possesses long white furs with big sized paws and long hair. This help them to blend with white snowy color of environment and the big sized paws prevents them from slipping in ice and also could dig in the ice to take shelter is hostile weather like snowstorm. They have thick layers of fat beneath the skin that keeps them warm. Also they are capable of swimming , in spite of a big body to facilitate their feeding on fishes on arctic sea.

Answer:
The process by which a compound increases it's concentration in the tissues of the organisms as it travel up the food chain is called biomagnfication.
When you scrape your original sample onto your agar plate, you cannot see how much single bacteria or where the individual bacteria is on your plate- since it's invisible to the naked eye. But when the bacteria start to multiply, you start to see the individual colonies. (from the single bacteria, it begins to multiply within 20 min. maybe after 1-2 days you'll see a colony, meaning there are millions of bacteria)
for example, if you take a water sample and spray it onto an agar plate, you won't know which parts of the agar plate the bacteria landed on. however, when they start to multiply from a single bacterium, you'll see where each starting bacterium was because now you can see a whole bunch of bacteria. (remember that a colony contains millions of bacteria- which allow it to be visible to the naked eye).
so you count the number of colonies, and that'll tell you how much bacteria you started with. if you look at the size of the colonies, you're only looking at how long you allowed the bacteria to incubate (since from the single bacteria that you started with, it's only multiplying and growing outwards).
