Explain. How mitotic cell division results in more cells that allow growth of the organism, can differentiate to create different cell types, and replace dead cells to maintain a complex organism.

Answer and Explanation:

All cells including the gametes contain chromosomes. Each gamete cell after cell division contains 23 chromosomes. After fertilization, the diploid number of chromosomes which is 46 is restored in the zygote.

Meiosis, a type of cell division, has two phases which eventually lead to the formation of four daughter cells with equal number of chromosomes. Gametes are haploid in nature and thus meiosis I involves separation of homologous chromosomes hence the reduction in the chromosome number. Meiosis II involves separation of sister chromatids in the daughter cells resulting in four daughter cells with 23 chromosomes.

Meiosis ensures that chromosoe number does not double with each successive generation as the resulting daughter cells are gametes, two of which must fuse to form a zygote.

The statement, which best explain the data is this: THE ZEBRAS HAVE A LOWER POPULATION GROWTH RATE THAN THE LIONS.

From the data given in the question, the population growth rate for lions and zebra can be calculated. The formula for calculating population growth rate is: Population growth rate = [Number of birth - Number of death] + [Number of immigration + Number of emigration]

For lions, we have: Population growth rate = [4 - 3] + [5 - 5] = 1 + 0 = + 1

For zebras, we have: Population growth = [5 - 3] + [1 - 4] = 2 + [-3] = 2 - 3 = - 1.

From the calculation above we can see that, the lions have a higher population growth rate than the zebras.

Zebras have a lower population
