Answer: The net movement is called diffusion.
Explanation:
Diffusion is the net movement of substance from region of higher concentration to a region of lower concentration.
The movement is due to constant and random motion characteristics of atoms ,ions and molecules due to kinetic energy. It continues until the concentration of substance is uniform.
Answer:
The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".
Explanation:
A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.
Answer:
Four to six days prior to the event, Maria should consume 550 g of carbohydrate daily and decrease to 220 to 275 g of carbohydrate daily 1 to 3 days prior to the event.
Explanation:
Carbohydrate loading is for constant supply of constant energy as ATPs for the skeletal muscles cells during high intense activity, to reduce fatigue, and increase performance for upmost performance.
The main objective is to sustaining muscle contraction during intense exercise
The practice involved increase in intake of high carbohydrate meals a few weeks before the commencement of the sporting activities. This is stored as muscle glycogen, as well as in the liver glycogen and brain.
The physiology involved the conversion of muscle glycogen to glucose -6-phopahate in the liver, and its entry into Glycolysis, and Krebs’s cycle to generate ATPs.
The use of muscle glycogen during strenuous exercise reduces blood glucose uptake, and ensured that its level is at a relatively constant value for the body homeostatic conditions, without exogenous carbohydrate intake
