IN between the G1 and the G2 phase of the cell cycle the cell's DNA replicates its DNA. The number of chromosomes stays the same, but the amount of DNA molecules duplicates.
Therefore, our cell with 6 chromosomes in the G2 phase has 6 chromosomes and 12 DNA molecules.
Answer : Corpus Callosum
Explanation : By the end of the preschool period, the brain structure called the <u>Corpus Callosum </u> becomes considerably thicker, with individual fibers that helps to co-ordinate brain functioning between the two hemispheres.
Corpus Callosum by definition is a thick band of nerve fibers that divides the cerebral cortex lobes into left and right hemispheres in the brain, which connects the left and right sides of the brain allowing for communication between both hemispheres.
Starting at least level up to the largest as organized by ecologists, see the chart below.
Answer: option C) species -> community -> biosphereD
Explanation:
Species refers to closely related organisms (plant or animal). When different species of organisms live together in a habitat where they feed on one another and become codependent on one another, a COMMUNITY has been formed.
A BIOSPHERE, however is composed of many ecosystems i.e different species of plants, animals and microorganisms relating with their environment. Thus, a biosphere = Communities + environment
