The segregation that occurs during meiosis results in a a. group of genetically identical cells b. reduction in the number of chromosomes per cell c. fertilized egg cell d. decrease in total number of cells per organism

The correct answer is option B, that is, reduction in the number of chromosomes per cell.

Meiosis refers to a unique kind of cell differentiation, which minimizes the number of chromosomes by half, forming four haploid cells, each genetically different from the parent cell from which they originated.

This procedure takes place in all the sexually reproducing single-celled and multicellular eukaryotes, including fungi, animals, and plants. In meiosis, the replication of DNA is succeeded by two rounds of cell differentiation to generate four daughter cells, each with half the number of chromosomes as the main parent cell.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
