Each enzyme has an optimum pH but it also has a working range of pH values at which it will still work well. This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. ... Catalase has an optimum pH of 9 and a working range of between pH 7-11. Hope this was helpful

Explanation:
Temperature is not a direct measure of thermal energy of a system the total energy depends on its temperature and what other factors?
Answer:
See explanation
Explanation:
There are two main factors that affect the magnitude of thermal energy of a system.
The thermal energy of a system depends on
i) Temperature of the body
ii) Mass of the body
Thus, the greater the mass of a substance at a particular temperature, the greater its thermal energy. Also, at a higher temperature, an object has greater thermal energy.

pills weighs 650mg and the technician weighs exactly 15.6g of pills, how many pill were dispensed
and placed into the pill bottles. Show all work with units.
Answer:
24 pills
Explanation:
650 mg/1000 = 0.65 g
(There are 1000 mg in one g)
15.6g/0.65g=24

Combustibles fosiles ¿Por qué son inflamables los gases naturales?¿Dónde están los gases naturales?¿Cómo podemos sacar el aceite?¿Dónde está el carbón?¿Es el combustible fósil una fuente no renovable? AYUDAA
Answer:
1) Los gases naturales son inflamables porque el natural contiene metano junto con una pequeña cantidad de otros gases orgánicos, lo que hace que una mezcla de entre 5 y 15% de concentración de gas natural con aire u oxígeno se queme por completo cuando se enciende.
2) El petróleo crudo, que son depósitos de hidrocarburos que se encuentran en depósitos naturales en las formaciones subterráneas de la Tierra, se obtiene perforando un pozo en el yacimiento de petróleo a través del cual se permite que una parte importante del petróleo fluya fuera del yacimiento bajo la presión del yacimiento para recibir procesamiento e instalaciones de almacenamiento en la superficie
3) El carbón se forma cuando se aplica compactación y calor a la turba que proviene de material vegetal muerto enterrado durante un período de varios millones de años.
4) Los combustibles fósiles se consideran una fuente de combustible no renovable porque la velocidad a la que se produce es más rápida que la velocidad a la que se forma.
Una fuente de energía renovable, como la energía eólica, es producida por la naturaleza tan rápido como se consume para generar energía.

about how many days does it take to go from one moon phase to another
Answer:
After one month, the Moon returns to the same location in the sky as the Sun and we see a New Moon again. The demo represents a month as 28 days for simplicity. But the real cycle of phases takes 29.5 days to complete.
What is the natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America? Is it the Jet Stream, the Gulf Stream, La Niña, or El Niño? This is a science question about weather.
Answer:
El Niño
Explanation:
The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.
El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years
During El Niño, the surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.
El Niño brings rainfall nd flooding to South America and droughts in the western United States

Which charge kept the electrons in the atom?
Enter the answer
Check it
Answer:
hope it helps
Explanation:
Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

Answer:
Option 3, The attraction between the can and the magnet is a pull.
Explanation:
The complete question is
Mr. Wang works in a recycling center. Recyclable materials arrive at the
center mixed together. Workers use magnets to separate steel cans from
other items. Which two statements are true about the force between a steel can and a magnet?
1 Gravity pushes the can toward the magnet.
2 The force between the can and the magnet is a noncontact force.
3 The attraction between the can and the magnet is a pull.
4 The attraction between the can and the magnet is a push
Solution
The force exerted by magnet on steel is the pull force. In magnets unlike poles attract each other (pull force) while the like poles repel (push force). Now, the steel or any ferrous object in the garbage when experience magnetic field develop magnetic field of their own in such a way that their north always faces the south of the external magnet or vice versa.
Hence, the force between a steel can and a magnet is pull force

Write a scientific explanation that compares the electrical forces of ethanol, hexane, and water.
Claim:
Evidence:
Reasoning:
Answer:
"Water and ethyl alcohol will both have dipole-dipole interactions.
Technically they will both have Hydrogen bonding, which is a type of dipole-dipole. This is due to the high electronegativity values of oxygen atoms compared to the carbon and hydrogen atoms the oxygens bond to. This causes regions of both of these molecules that have partial negative charges and other regions wind up with partial positive charges.
Hexane will not have any dipole-dipole interactions because it is a non-polar molecule. The intermolecular forces between hexane molecules will be dispersion forces."

A microwave oven uses electromagnetic radiation to heat water molecules in food or drink. This radiation has a frequency of 2.45 x 10⁹ Hz. Calculate its energy
Answer:
1.62 × 10⁻²⁴ J
Explanation:
Step 1: Given and required data
Frequency of this radiation (ν): 2.45 × 10⁹ Hz (2.45 × 10⁹ s⁻¹)Planck's constant (h): 6.63 × 10⁻³⁴ J.sStep 2: Calculate the energy (E) of this electromagnetic radiation
We will use the Planck-Einstein's relation.
E = h × ν
E = 6.63 × 10⁻³⁴ J.s × 2.45 × 10⁹ s⁻¹ = 1.62 × 10⁻²⁴ J
