The scientific methodology is also referred to as scientific method, it is the problem solving approach that is used in science. The scientific method ls made up of the following steps: observation, formation of research question, formation of hypothesis, making prediction and conduction of experiment {testing out the prediction}.
Answer:
Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy
Muscle cramps are caused when the muscle takes longer than normal to relax after a contraction. During contraction, the myosin heads attach on their binding sites on the actin filament and pulls on the filament hence shortening the sarcomeres. For the myosin head to release its binding site on the actin filament, ATP attaches to an active site on the myosin and is hydrolyzed to ADP and Pi. This causes relaxation after a contraction cycle. Cramps, therefore, may be due to depletion of ATP molecule in the muscles cells.
Another reason for cramps may be a high amount of calcium in the muscles that bind to troponin on the actin filaments. This exposes the myosin binding sites longer hence promotes the formation of cross-bridge even when the contraction of the muscle is not intended anymore.
Transcription is when the Dna is being copied by the mRNA
Translation is when the mRNA is turning the DNA into another "code". So the t RNA can drop off the right protein.
