Answer:
Advantages:
Low Level Irradiation kills bacteria and parasites.
The Nutrition value of of irradiated food is the same as regular food with less bacteria.
Irradiation makes fruits and vegetables riper and spoil slower.
Disadvantages:
Irradiation will increase cost of food.
The percentage of radiation as always being negative will also make
Irradiated food are not widely available yet.
Answer:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0)
y-int: (0, 2)
Explanation:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0) ==> When y=0
y-int: (0, 2) ==> When x=0
Answer:
Baldness
Explanation: hair loss, or absence of hair. Baldness is usually most noticeable on the scalp, but can happen anywhere on the body where hair grows.
Answer:
Genetic drift
Explanation:
Genetic drift can also be referred to as allelic drift, it refers to the variation in allelic frequencies within a particular population over a period of time. It can also be referred to as the random fluctuations in the number of genotypes within a population. Genetic drift is not influenced by the environment and is usually more pronounced in a small population of organisms.
For example, a population of birds can consist of green feathers and blue feathers with the green feathers as the dominant allele, but as a result of random fluctuations, the offspring may all be with green feathers and hence could eliminate or reduce the allele responsible for blue feathers over time.
