Where in your body do mechanical and chemical digestion occur? Digestion is a process that converts nutrients in ingested food into forms that can be absorbed by the gastrointestinal tract. Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine. What mechanical and chemical digestion occurs in […]

What happen when you perform a cardiovascular activity? Cardiovascular exercise is any vigorous activity that increases heart rate and respiration and raises oxygen and blood flow throughout the body while using large muscle groups of the body repetitively and rhythmically. What is the relationship between physical activity and cardiovascular fitness? What is the connection between […]

Which one of the following statements about stretching is most accurate? You should plan a program of stretching exercises that involves most of your joints is the most accurate statement about stretching. You should plan a program of stretching exercises that involves most of your joints is the most accurate statement about stretching. Which one […]

Is K or Br bigger? Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms. Does S or O have a larger atomic radius? Consequently for […]

Who is the most powerful nuclear country? Countries with the most nuclear weapons | US is not number 1, China adds 30 warheads within a year No 3 | Country: China | Number of nuclear weapons: 320 (Image: Reuters) No 2 | Country: US | Number of nuclear weapons: 5,800 (Image: Reuters) No 1 | […]

Why force is directly proportional to pressure? From equation (1) it is evident that as force increases, pressure also increases and as force decreases pressure also decreases since force is in the numerator. Or pressure is directly proportional to the applied force. Whereas as the area increases, the pressure decreases. i.e. it increases with the […]

How many coordinate systems are there? In this article we mainly discuss two types of coordinate systems. What is the difference between phi and theta? Theta is the same as the angle used in polar coordinates. Phi is the angle between the z-axis and the line connecting the origin and the point. How do you […]

What enzymes do lysosomes contain? Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label. What organelle is responsible for respiration? The “powerhouses” of the […]

What are the 3 equations for power? Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = […]
