Helen [10]

Answer:

Averaging the fitness of its members.

Explanation:

The fitness of a whole population can also be determined by averaging the fitness of its members. Absolute fitness is the ratio between the number of individuals with a genotype before selection versus after selection. Fitness is usually discussed in terms of genotypes, or collection of genes.

Brief summary of conservation of forests &amp; wildlife <br><br> least 10 page
wel

With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.

Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.

More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.

Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.

The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.

Answer:

Organization helps us make sense of our surroundings. Some people organize their sock drawers

by color. Books in a library are often organized by topic. Food in a grocery store is organized so we

to know just where to find something.

For scientists, organization is an essential tool. The organization of similar organisms into groups

helps scientists understand how living things are related. It also allows scientists to communicate

about all forms of life. For example, suppose a scientist in the United States writes about a specific

group of animals. Other scientists around the world will know exactly which group of animals the

writer is referring to. But, how do scientists decide which organisms to group together? Do they use

a particular process?

Scientists classify organisms in different ways.

Scientists organize the living world using a process called taxonomy, which is the science of

classifying organisms based on shared structures, functions, and relationships to other organisms.

For example, organisms can be classified based on their cellular

structure. Organisms that have nuclei are eukaryotes. Eukaryotes

also have organelles, or specialized structures bound in a

membrane. They are in a different group than prokaryotes, which

are organisms that do not have nuclei. Also, many unicellular

organisms are in a different group than multicellular organisms.

For example, bacteria are unicellular organisms. They are in a

different group than animals, which are multicellular. Living things also can be classified

according to the way in which they

obtain food. Think about the

differences between plants and

animals. Plants make their own food and are called autotrophs. Animals must consume other

organisms and are called heterotrophs. This difference classifies

plants and animals into two separate groups.

Method of reproduction can be used to classify organisms into

even smaller groups. The two main reproductive methods are

asexual and sexual reproduction. In asexual reproduction, only

one parent is involved in producing offspring. In sexual

reproduction, two parents are involved: a male and a female
