Answer: B
Explanation:
Honestly, I would say a word. Since it states that codons are read by mRNA molecules in groups of three, they could be easily compared to words, not letters.
Answer:
diverse proteins embedded in a phospholipid bilayer
Explanation:
According to fluid mosaic model the cell membrane is made of bilayer of phospholipid. Many proteins are embedded in this bi layer. Carbohydrate and cholesterol are also found in different forms. Carbohydrate can either be attached to the embedded protein in which case it is called as glycoprotein or it can be connected to the lipid molecule in layer and called as glycolipid.
Proteins can be found in two forms too. They can either be embedded in the layer i.e. they can penetrate single or both layers. These proteins are called as integral proteins. They can also be present on one side of the membrane and not penetrate the lipid bilayer in which case they are called as peripheral proteins.
The options attached to the above question are given below:
A. A table of classification that is based only on physical characteristics
B. Eight levels of taxonomic categories that are used to classify organisms
C. A branching chart that depicts evolutionary relationship among organisms
D. Organisms organized based on structure and genetic comparisons
ANSWER
The correct option is C.
A phylogenetic tree refers to a diagram, which represents evolutionary relationships that exist among organisms. Phylogenetic tree has many branches, which represents how different species evolved from a series of common ancestors. The relationships among the living organisms is usually based on the similarities and the differences in their physical or genetic features. A phylogenetic tree can be described as rooted or non rooted based on the depth of information they offer.
