Answer:
Explanation:
Mitosis. Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
Answer: Precipitation occur more frequently than evaporation over land.
Explanation:
Precipitation refers to the water vapour that fall from the atmosphere in form of rain, snow, sleet, freezing rain or hail. It delivers water from the atmosphere to the Earth. Precipitation occur more on the land than evaporation, most water that teaches the surface of the Earth fall back on the land and fill the inland water, rivers , storages,e.t.c.
Evaporation occur frequently in the ocean because it is expose to the sun and most water that is evaporated from the ocean fall back to the ocean as precipitation.
Answer:
E) Either anaphase I or II
Explanation:
Failure of segregation of homologous chromosomes during anaphase I or failure of segregation of sister chromatids during anaphase II leads to the presence of the abnormal number of chromosomes in resultant gametes. In the given example, the egg mother cell with 48 chromosomes (24 pairs) would enter meiosis I but the failure of one pair of homologous chromosomes to segregate from each other followed by normal meiosis II would result in the formation of two gametes with one extra chromosome and two gametes with one less chromosome.
On the other hand, if the nondisjunction occurs at anaphase II of meiosis II, two normal gametes, one gamete with one extra chromosome and one gamete with one less chromosome will be formed. Therefore, nondisjunction at anaphase I or anaphase II would have resulted in the production of eggs with one extra chromosome.
Answer:
Archaea
Explanation:
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
