The order from the longest to the largest will be; Eon, Era, Period, Epoch.
Eon is the longest division of geologic time. Epoch is the shortest division of geologic time, only present in Cenozoic Era. Era is the second longest division of time, marked by sweeping changes in the fossil record. Period is the time division which is longer than an epoch but shorter than an Era.
The correct answer is option B, that is, the release of large amounts of greenhouse gases can change Earth's climate.
Fossil fuels refer to hydrocarbons, mainly fuel oil, coal, or natural gas, produced from the leftovers of dead animals and plants. The use of fossil fuels has allowed large-scale industrial development and hugely supplanted water-driven mills, as well as the combustion of peat or wood for heat.
The burning of fossil fuels by humans is the biggest source of emissions of carbon dioxide that is, one of the greenhouse gases, which permits radioactive forcing and donates to global warming. One of the dreadful effects of global warming is the change in the climatic condition of Earth.
Answer: different organisms have different chromosome numbers
Explanation: eukaryote cells have more than one chromosome
chromosomes are present in most cells all the time (not in erythrocytes), but cannot be visualised except during telophase of mitosis or meisosis
bacterial cells don’t have a nucleus
Answer: A small middle portion of the sperm contains the mitochondria. The tail of the sperm, sometimes called the flagellum, is a slender, hairlike bundle of filaments that connects to the head and middle portion. The tail gives the sperm cell movement. It whips and undulates so that the cell can travel to the egg.
