Mutation can cause instant adaptation while natural selection is the process by which adaptation occurs over a series of generations.
Answer:
it regulates blood volume and blood pressure.
Explanation:
Cell membrane, Organells, flagella
Answer:
it is located 1000 nucleotides upstream of the gene’s core promoter - true
it is located 1000 nucleotides downstream of the gene’s core promoter- true
it is in the gene’s coding region - False
Explanation:
These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.
The correct answer is a - Lipid
Lipids are not considered as macromolecules because unlike proteins, carbohydrates and nucleic acids which polymers, lipids are composed of a single unit made up a glycerol backbone to which two or three fatty acids are linked.
Lipids are not polymers made up of individual subunits called monomers. They contain only one molecule and are not macromolecuels.
Examples of lipids include waxes, steroids, phospholipids and detergents. Lipids are generally hydrophobic and insoluble in water.
