Answer:
Diversity of the community = 2.097
Explanation:
Given:
Number of pitch pines = 134
Number of douglas firs = 24
Number of red pines = 53
Find:
Diversity of the community
Computation:
Simpson's diversity index = N(N-1)/Σn(n-1)
Particular n n(n-1)
Pitch pine 134 17822
Douglas firs 24 552
Red pine 53 2756
Total N=211 21130
So,
D= [211(211-1)] / 21130
D = 2.097
Diversity of the community = 2.097
Answer:
D
Explanation:
Because there has to be competition or one population wouldnt decrease and the other wouldn't increase due to survival and reproduction the population doesn't always have to be below the carrying capacity because it can also do it when its above and natural selection can act on traits determined by different alleles.
C. The exact amount of nonrenewable energy resources is not currently known.
In addition to several other factors, the overall risks of environmental chemicals depend on genetically determined variations in the <u>proteins</u> involved in the transport, metabolism, and excretion of these chemicals.
Environmental Chemicals
Various chemicals and compounds present in the air, food, soil, water, dust, etc are called environmental chemicals. In humans, there are more than 400 listed environmental chemicals. Most of these chemicals are already present in the environment while the others were manufactured for humans to use. Some chemicals may be harmful to all humans while others may be selectively harmful to certain individuals and they are commonly referred to as allergens. Even though there are many environmental chemicals around a human being, most of them are not harmful.
The risks involved in exposure to chemicals depend on variations in the proteins present in various metabolic functions. If the functions of the proteins are hampered then it will create a cascade of errors that may end up causing serious harm to the person.
