Answer:

$3.5 * 10^6$

Explanation:

Hydrogen peroxide is a harmful chemical which is broken down into oxygen and water by the catalase enzyme. The oxygen gas is released in to the air for next two minutes till reaches a steady rate and hence decrease further in an hour.

The speed with which a catalase decompose hydrogen peroxide is $3.5 * 10^6$ times per second

In absence of catalase, H2O2 will be decomposed at a rate slower by $3.5 * 10^6$ times

It will take 1,000,000 times slower for Hydrogen Peroxide to decompose

Hydrogen peroxide is a toxic compound that usually destroys cell membrane. Also, it is a byproduct of metabolism that must be broken down quickly because it can cause damage to the cells. Moreover, catalase is an enzyme that is found in almost all the living organism and function by catalysing the decomposition of hydrogen peroxide into water and oxygen. However, the decomposition of hydrogen peroxide is very slow and cannot sustain human life in the absence of catalase.

Pls help!!! osmosis help needed!!

Answer:

1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic

Explanation:

1. Given the image, it shows there is 10% glucose outside the cell.

2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)

3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.

2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.

3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).

3. The cell will swell, since water is getting moved in.

6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.

Hopes this helps!^^ I tried the best I could at explaining.

Why does a cell need to grow during interphase before it divides during mitosis? What would happen if cells did not grow before

dexar [7]

Answer:

the cell copies every oranelle in preperation for mitosis if it didnt go through interphase it woughd just split the organelle in half, interphase copies the dna and organelles .

Explanation: also the cell spends most of its life cycle in interphase.

Explanation:

electromagnetic waves: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

radio waves: Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.

microwaves: Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.

infrared: Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.

visible ray: The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers

ultraviolet:UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. Different UV wavelengths and intensities are used for different purposes

xray:An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz)

gama ray :A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.
