Macronutrients are a substance required in relatively large amounts by living organisms, in particular.
a type of food (e.g., fat, protein, carbohydrate) required in large amounts in the human diet.
a chemical element (e.g., potassium, magnesium, calcium) required in large amounts for plant growth and development.
a chemical element or substance required in trace amounts for the normal growth and development of living organisms.
Energy drinks tend to lack nutrients, and instead contain vitamins, minerals, and stimulants that interact with metabolic pathways to provide energy.
Metabolic pathways- A metabolic route is a series of activities or relationships between genes and associated byproducts that leads to the synthesis or modification of a system component that is necessary for a biological system to function properly.
Genes- The fundamental genetic component transferred from parent to child. Genes are composed of DNA sequences and are organized sequentially at specified sites on chromosomes inside the cell nucleus.
DNA- The molecule found inside cells that carries the genetic material necessary for an organism to grow and operate.

When cloning by restriction digest and ligation, you use restriction enzymes to cut open a plasmid (backbone) and insert a linear fragment of DNA (insert) that has been cut by compatible restriction enzymes. An enzyme, DNA ligase, then covalently binds the plasmid to the new fragment thereby generating a complete, circular plasmid that can be easily maintained in a variety of biological systems. Read on for an in-depth breakdown of how to do perform restriction digests.
Answer:
I'm sorry but there is no picture above you-
Answer: D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.
Hypothesis A and B both are suggesting that caffeine intake is related to higher heart rate. But hypothesis B is proving it more certainly by suggesting the affects of caffeine intake on heart rate. As, heart rate of most people will be higher 30 minutes after they drink a cup of coffee is testifying the fact, that higher heart rate is related with caffeine intake.
Therefore, hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.
