Answer:

The correct answer would be sexual reproduction.

Sexual reproduction leads to the development of genetic variation in the offspring in two ways:

Crossing over: Exchange of genetic material between non-sister chromatids of homologous chromosomes takes place during the formation of gametes.

Fertilization: The two gametes fertilize to form a zygote. Thus, the genetic material of zygote is contributed by both the parents.

These two factors form a new combination of genes in an offspring which is different from either parent.

sexual reproduction

Sexual reproduction provides genetic variation because the sperm and egg that are produced contain different combinations of genes than the parent organism. Sexual reproduction involves meiosis which is the process of a cell doubling its DNA, shuffling its genes and then dividing the shuffled DNA among four cells.

zheka24 [161]

A community refers to the total number of populations that inhabit a specific location or area. This is part of the levels of organization of life. Arranged from the least complex to most complex it falls 8th in the category. Below are the organization of life:

a. Organelles - the basic part of a living organism. It refers to the different structures of the cell, whether prokaryotic or eukaryotic. (Ex. Mitochondria, nucleus)
b. Cells - building blocks of life that are composed of different molecules responsible for the function of an organism. (Example: prokaryotic, eukaryotic cells)
c. Tissues - combinations of cells that carry out a specific function in an organism. (Example: Human skin)
d. Organs - collections of tissues that perform specific functions. (Ex. heart, lungs)
e. Organ Systems - composed of interconnected organs that function as a whole. Many organisms, particularly mamamals, are composed of organ systems. (Ex. respiratory, circulatory systems)
f. Organisms – individual entities that specifically make-up a population. (Ex. Each tree in the forest is an organism, each animal in sea is an organism)
g. Population – species living within a specific location. It could be the same or different species that inhabit a place. (Ex. Birds are species in the forest as well as bears)
h. Community – refers to the total number of populations that inhabit a specific location. (Ex. All of the trees, insects, birds that inhabit the forest are a community)
i. Ecosystem – consists of all living things that function together as a group which also includes the non-living parts of the environment. (Ex. Rain water, nitrogen in the soil)
j. Biosphere – the highest organization of life that consist of all the collection of ecosystems in the planet. It includes the land, air, water, even the atmosphere of the planet.
