A cellular organelle is a structure in the cell that performs a specific function.
Nucleus - stores cell's DNA; DNA replication occurs here
Ribosome - produce protein; "factories" of the cell
Mitochondria - breaks down food for energy to be used by the cell; "powerhouse" of the cell
Vacuole - store materials such as food, water, sugar, minerals, and waste products
Endoplasmic reticulum - carry materials throughout the cell; "transport system"
Answer:
c) It introduces a premature stop codon into the mRNA
Explanation:
Nonsense mutation is a type of point mutation (single nucleotide base is changed) which leads to premature stop codon. Stop codons are also called nonsense codons and that is way this type of mutation is called nonsense mutation. As a consequence, synthesized protein is incomplete and shorter than it should be (truncated protein), usually nonfunctional.

It is true that the gametophytes grow directly from the sporophyte
Answer: Option C
<u>Explanation:</u>
Conifers are distinct by the presence of evergreen needle shaped leaves and seeds that are generally attached to the cone. The conifers are generally pines which grow into tall trees and bonsai varieties are the smallest. They do not produce seeds in the fruits like other trees rather store it in a thick woody cone where it can be protected during forest fires.
In conifers the process from pollination to fertilization takes about a year. The plant in which the gametophyte grows is called as the sporophyte. This sporophyte is where the male and female gametes fuse together to form the first cells the zygote. Then this zygote develops into a seed. This seed is then disbursed through wind and end up forming a new baby plant called the sporophyte.
