D. An element donates an electron to another element.
The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.
Explanation:
Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".
In meiosis, cell division will occur two times. It shall be called Meiosis I and Meiosis II. And Meiosis happens to our sex cells, egg for female and sperm cells for the male. There four stages in Meiosis I, Prophase I will happen when who homologous chromosomes exchange DNA. Metaphase I will happen when the pair move together in the center. Anaphase I is when the who homologous chromosomes are pulled apart to opposite poles. Telophase I is when the the first division of the chromosomes happen. Producing two 24 chromosomes cells. The nest division will produce haploid or 12 chromosome cells. In Propase II, the nuclear walls will disappear once again, in the Metaphase II the cells will meet again in the center. In Anaphase II the chromatids will be pulled apart. And then lastly in the Telophase II, the chromatids will not be 2 haploids. So in Meiosis, 4 sex cells are produced.
The first law. Planets orbit is an ellipse with the Sun at one focus.
