Answer:
10: Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.
19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).
20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.
Explanation: Hope those are the only answers you needed. I just saw the stars next to them and figure those were the only ones you needed.
Answer: alpha bond
Explanation:
The carbohydrates popularly called sugars are energy nutrients formed by carbon, hydrogen and oxygen atoms. It is the main energy source of the man and also has a structural or plastic role (formation of parts of cells such as the cell wall, or tissues, such as the exoskeleton chitin of the insects and crustaceans - crab). The small intestine's main mission is to complete the digestion of the chyme. In its passage through the duodenum, it suffers the action of pancreatic and intestinal juices and bile. In fact, it is in the duodenum that most digestive secretions are produced. The foods complexes are thus transformed into simple elements, easily assimilable by the body.
Enzymes are protein catalysts responsible for most of the chemical reactions of the organism, is found in all tissues. Amylase acts in the intestine hydrolyzing glucose polymers (starch, amylopectin, and glycogen). The bonds that hold the monosaccharides together and which are easily digested by pancreatic amylase in the intestine are known as alpha bonds. Some examples of sugars that have alpha bonds are sucrose, maltose, and starch.

Answer:
True
Explanation:
<em>The three groups of organisms have the capability to cause different diseases in humans and other animals. The specific ones among them that can cause diseases are said to be pathogenic while those that are incapable of causing diseases are said to be non-pathogenic.</em>
The right answser is Chromosomes.
After DNA replication during cell cycle interphase, the chromosomes are composed of two identical chromatids attached at the centromere. Each chromatide is formed of a molecule of DNA (the nucleofilament) associated with proteins, the histones, around which it winds to form nucleosomes. At the ends of each chromatid are telomeres, consisting of repetitive DNA sequences that provide protection for chromosomal endings. Telomeres and centromere do not encode genetic information, it is non-coding DNA.
