Answer: Haploid cells have 23 chromosomes while diploid cells have 46 (23 pairs) chromosomes
Explanation: Haploid cells are produced in a type of cell division called meiosis. In meiosis, parent cells undergo two cell divisions to produce four daughter cells with half the number of chromosomes in the parent cell. Diploid cells are produced by a type of cell division known as mitosis. In mitosis, parent cells undergo one cell division to produce two identical daughter cells that have the same number of chromosomes as the parent cell. Gametes undergo meiosis while somatic cells undergo mitosis.
I’d say the first option. “The disposal of radioactive wastes is an intended benefit.”
I’m sorry it it isn’t correct.
Answer:
Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones.
Explanation:

Their higher classification is already considered as human.
