Ionic bonds result when electrons are tranfered between atoms. Covalent bondsresult when valence electrons are shared between atoms. You should be able to identify whether an ionic or covalent bond is being formed between atoms.

Answer: all animals are multicellular
Explanation: All animals are Eukaryotic, I.e they are multicellular organims which means they posses different organs and cells that helps in the survival of the animal.
Answer:
Phenotypes
Explanation:
If a trait is simply controlled by 2 alleles, there is a maximum of three phenotypes that can be produced from the alleles. Either the individual is homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa). This would give a maximum of 3 different phenotypes, potentially only 2 phenotypes if the trait is completely dominant
In contrast, if a trait is controlled by lots of alleles (either at the same gene or different genes) there are many more possibilities for the final phenotype, as each allele might contribute something slightly different.
The correct answer is Axial Position
Reason:
When axial groups lie on the opposite sides of the ring, they are capable of holding large molecule and are stable as there is less steric hindrance between those groups. Also the molecular distance between them is large.
