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 […]

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 […]

What factors influence potential and kinetic energy? Since the state of motion of an object can change with time, the kinetic energy of an object can also change with time. The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to […]

How does photon interact with matter? Photons interact differently in matter than charged particles because photons have no electrical charge. give up their energy via secondary interactions (mostly ionization). The interaction of photons with matter is probabilistic, while the interaction of charged particles is certain. What happens if an incident photon collides with a moving […]

Are there any full blooded aboriginal peoples left 2020? Yes there are still some although not many. They are almost extinct. There are 5000 of them left. There are 468000 Aboriginals in total in Australia in which 99 percent of them are mixed blooded and 1 percent of them are full blooded. What is wrong […]

Is current directly proportional to voltage? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is relation between voltage and current? […]

How does a roller coaster go up a hill? A roller coaster does not have an engine to generate energy. The climb up the first hill is accomplished by a lift or cable that pulls the train up. The higher the hill the coaster is coming down, the more kinetic energy is available to push […]

What are the 5 variables? There are six common variable types: DEPENDENT VARIABLES. INDEPENDENT VARIABLES. INTERVENING VARIABLES. MODERATOR VARIABLES. CONTROL VARIABLES. EXTRANEOUS VARIABLES. How many independent variables should an investigation have? one independent variable What’s the dependent variable in science? The dependent variable is the variable that is being measured or tested in an experiment. […]

What do plants use to make their own food? The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl). All photosynthetic organisms […]

How do you calculate sound pressure? Sound pressure level (SPL) calculator – formula & step by step calculation to measure the logarithmic RMS value of the sound or acoustic pressure caused by the sound wave relative to a reference value in decibels. SPL (dB) = 10 log10(p2/po2). How do you convert pressure to dB? Sound […]
