Answer:
Angiosperms are vascular plants bearing the seeds in fruits or mature ovaries whilst gymnosperms are other types of the plant which bears the seeds directly on the sporophylls but without any cover.
Explanation:
Examples of gymnosperms include cypress,pine, redwood, spruce and ginkgo.
Examples of angiosperms include apple, banana,peach, cherry and orange.
Also, angiosperms are seeds producing flowering plants whose seeds are enclosed within an ovary.
Gymnosperms are also seeds producing non flowering plants whose seeds are unenclosed.

Coral can host symbionts that will help in their growth. There are algae that could live on the coral surface, giving them some of the energy from photosynthesis and help in calcification while the coral protects the algae. </span>The symbiosis will be formed when nearby algae attach to the corals. A stress on the coral can cause the algae to eject the algae.

Answer:
Answer is C.
Explanation:
For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.
Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
