<h2><em>what is an atomic mass of an atom referring to?</em></h2>
- <em>Lr. The atomic mass of an element is the average mass of t<u>he atoms of an element measured in atomic mass unit </u>(amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.</em>

According to the United States Department of health and human services, in order to obtain sufficient physical activity for health, the Americans should perform the following activities:
1. 75 minutes per week of vigorous-intensity activity.
2. 150 minutes per week of moderate intensity activity.
3. Or, an equal combination of both moderate and vigorous-intensity activity
May I please see the entire table so I can answer your question.
The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium. It is incredible the complex array of macromolecules that can be built starting with these simple elements.
Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.
Explanation:
Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)
Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>
After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>
