Aneli [31]

The correct order of arrangement of energy resources from highest to lowest usage world wide is fossil fuels, nuclear energy and geothermal energy.

A fossil fuel is a energy source formed by the dead remains of living organims over millions of years through the natural process. It includes the coal, petroleum and the natural gas which are the highly used energy resources all over the world. Nuclear energy is the energy generated during the fission or fusion of nuclear reactions which is used to generate electricity. It is one of the low carbon power methods to generate electricity. Geothermal energy is the thermal energy or the heat energy stored in the earth which is used to produce electricity.

Thus, fossil fuels forms the first energy resource to be highly used worldwide.

e-lub [12.9K]
Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation. 
<span>In sexual life cycles, meiosis and fertilization keep the number of chromosomes constant from generation to generation. </span>

T lymphocytes that are capable of killing invading organisms are
AlladinOne [14]
The T lymphocytes capable of killing invading cellular organisms such as bacteria, protists, or fungi are cytotoxic T cells also known as CD8+ cells. These cells are capable of recognizing whether a cell has a major histocompatibility complex I (MHC I) surface protein or not. Those with absent MHC I surface protein will be killed by the cytotoxic T cells. Those with the MHC I surface protein expressing an invading antigen will also be killed by cytotoxic T cells. Those with the MHC I surface protein without an antigen will be spared by the cytotoxic T cell.
