Answer:
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond)
Explanation:
Answer;
Atomic number Tc = 43 , which is equivalent to the number of protons in nucleus.
Number neutrons = mass number - number of protons = 99 - 43 = 56 neutrons .
Number of electrons = number of protons - charge = 43 - (+7) = 36 electrons
Explanation;
-Atomic number is the number of proton in the nucleus of an atom of a given element. Mass number is the total number of protons and neutrons in the nucleus of an atom. A neutral atom has equal number of protons and neutrons.
-Isotopes are atoms of the same element with the same atomic number but different mass number.
<em>the correct option for this is B>></em>
The lower invertebrate phylum that has the greatest diversity is called Arthropod. An Arthropod is an invertebrate animal that has a segmented body, an exoskeleton, and paired jointed appendages. Arthropods include an incredibly diverse group from the phylum Euarthropoda, which includes myriapods, <span>arachnids, insects, and crustaceans.</span>
