Answer:
1. True
- Those are compounds
2. False
-They are actually polar molecules
3. True
-Acids are molecules that give away a type of subatomic particle
4. False
-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.
5. False
-An isotope is an atom that has gained an extra neutron.
6. True
-Oxygen is more electronegative than most of the halogen elements.
7. True
-Cellulose and starch are both polymers made from a glucose monomer.
8. True
-During DNA replication both strands that make up the double helix are used as a template that new strands copy.
9. True?
- I think the question is referring to a codon/nucleotide triplet, because each base cant specify a single amino acid and nucleotide triplets are made up of three nucleotide bases so id say true.
10. True
-Side chain groups vary in size, shape, charge, hydrophobicity, and reactivity, which makes them unique.
A bound formed by an electrical attraction between two oppositely charged ions is an ionic bond.
I hope this helps.
Rough Endoplasmic Reticulum. it has a rough surface and is covered in ribosomes.
Answer: Non disjuntion occurs during prophase 2 in meiosis 2. one pair of sister chromatids don not separate from each other. As a result three cell have normal haploid chromosomes but one cell have extra chromosome while other have one less chromosome. It lead to the phenomenon of non dis junction.
