When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2) This range change in reaction rate suggests

that liver is a substrate for hydrogen peroxide

that liver contains lots of germs

the liver contains an enzyme that breaks down hydrogen peroxide

that hydrogen peroxide is a powerful enzyme

Answers

Answer 1

Answer: C

Explanation:

Catalyst is one enzyme from liver that breaks down harmful hydrogen peroxide into oxygen gas and water

Answer 2

When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide decomposes into water and oxygen. This suggests the liver contains an enzyme that breaks down hydrogen peroxide. Thus, the correct option is C.

What is Catalase?

Catalase is a common enzyme which is found in nearly all living organisms which are exposed to oxygen gas. Catalase is a key enzyme which uses hydrogen peroxide, a nonradical Reactive Oxygen Species, as its substrate. Catalase enzyme is responsible for the neutralization through decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell system which is also essential for the cellular signaling processes.

Catalase is an enzyme which causes or speeds up a reaction without being affected during the reaction. The enzyme catalase speeds up the breakdown of hydrogen peroxide into water and oxygen gas.

Therefore, the correct option is C.

Identify the locations within the human body for Hyaline, Elastic and Fibrocartilage.

Answers

Answer:

A flexible connective tissue, known as cartilage varies from bones in many ways, its microcomposition is less developed in comparison to the bone and is avascular. It is not supplied with nerves and thus depends upon the process of diffusion to attain nutrients. The three kinds of cartilage are fibrous, hyaline, and elastic.

Of these the most widespread kind is the hyaline cartilage, it looks like glass. It is witnessed in embryos, where the formation of bone takes place as hyaline cartilage, which ossifies later. In adults, it is found on the tips of the ribs, on the articular surfaces of the long bones, the parts of the skull, and the rings of the trachea.

Fibrous cartilage is witnessed in the pubic symphysis and intervertebral discs and exhibits many collagen fibers.

Elastic cartilage is witnessed in the internal support of the external ear and the epiglottis and is yellow, springy, and elastic in characteristics.

where do plants get their nitrogen

Answers

Although there's plenty of nitrogen in the air, it's not in a form plants can use. They can only absorb nitrogen in the form of ammonium, nitrite, and nitrate. One way plants have access to these forms of nitrogens is decomposition of organic matter by soil organisms. Another source of usable nitrogen are mutualistic relationships between plants and bacteria. By providing nitrogen-fixing bacteria a place to live and feeding them with carbohydrates, plants get nitrogen in the form of ammonium. Plants that can do this include most legumes which form relationships with Rhizobium bacteria, and other plants like alder, bayberry, California lilac, and Russian olive that support Frankia bacteria on their roots.
There are also free-living nitrogen-fixing bacteria, as well as cyanobacteria that grow on the surface of plants or the soil, that add small amounts of plant-usable nitrogen to the soil. Lightning also generates usable nitrogen compounds.
Chemical fertilizer is a major source of plant-usable nitrogen. But other human activities, like the burning of fossil fuels and livestock operations, inadvertently produce widespread, nitrogen-enriched rainfall.

two layers of warm air, one on top of the other

a layer of warm air over a
layer of cold air

a layer of cold air over one of warm air

Answers

Answer:

the answer is that"a layer of warm air over a layer of cold air" which can be caused by factors like formation of fronts, scattering, advection.

The condition important for a temperature inversion is a layer of warm air over a layer of cold air. Hence option C is correct.

What is temperature?

Temperature is defined as any scale used to represent how hot or cold something is, including the Celsius and Fahrenheit scales. Food, beverages, agriculture, and medical care for both people and animals all depend heavily on temperature. Temperature also frequently affects our general health in a number of ways. In facilities used for medical cold storage, maintaining optimum temperatures is crucial.

The usual behavior of temperature in the troposphere is reversed by a phenomenon known as temperature inversion. A layer of warm air sits on top of the layer of cold air beneath this meteorological occurrence. It is brought on by static atmospheric circumstances, while it can also be brought on by air moving horizontally or vertically.

Thus, the condition important for a temperature inversion is a layer of warm air over a layer of cold air. Hence option C is correct.

A 50 mL sample of soup was found to be contaminated with E. coli. A dilution of the soup was prepared by adding 14 mL of the soup to 20 mL of water. This was then diluted 1/60, and finally 10-3. Then .25 was added in to 2 plates. The first plate had a colony count of 72 and second had 65.


To do the dilution series does the 50 need to be added?

Answers

Answer:

The answer is "[tex]\bold{4.0 \times 10^7 \ \frac{CFU}{mL}}[/tex]"

Explanation:

The very first thing we must do is figure out where the plate was really a countable sheet.  By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range.  We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.

[tex]\to 72+ \frac{65}{2} = 68.5[/tex]

We need to calculate its dilution factor for both the second item. Increase for all of this  

All of the dilutions you also made:

[tex]\to \frac{7}{17} \times \frac{1}{60} \times \frac{1}{1000} \\\\= \frac{7}{1020000}\\\\= 6.8 \times 10^{-6}[/tex]

[tex]\to \frac{CFU}{mL} = \frac{Colonial \ number}{Dilution \ Factor \times Volume \ plated}\\\\[/tex]

            [tex]= \frac{68.5}{6.8 \times 10^{-6} \times 0.25 \ mL} \\\\ = 4.0 \times 10^7[/tex]

To solve this problem we need to use Avogadro's number, which is defined as the number of molecules (or atoms, in the case of an element) that are in 1 mole:

There are 6.023x10²³ molecules in 1.0 mole

With that information in mind, we convert lactic acid moles into molecules:

Answer:

D. They are usually transmembrane proteins

Explanation:

Membranes are made up of a phospholipid bilayer, cholesterol and various mimbrane proteins. The lipids consist of outward facing hydrophilic heads and inwards facing hydrophobic tails. Cholesterol molecules help maintain membrane fluidity.

Transmembrane proteins play an important role. These help to transport various molecules and ions like glucose, and Na+ across the selectively permeable bilayer. These are permanently embedded within the membrane as integral membrane proteins, and do not move around.

Compare the wind speeds of the edge of a hurricane on earth and the edge of the great red spot on jupiter what is your conclusion

Answers

Answer:

Jupiter is approximately 318 times bigger than the earth. So, it is expected that its hurricanes would be very massive as well.

Explanation:

A hurricane is a tropical cyclone, a storm with a very violent wind. It is labeled a cyclone because of its cyclic nature.

The Great Red Spot of Jupiter is a giant storm about twice as large as Earth, which in its southern hemisphere orbits the globe. This at least twice the speed of the most dangerous and most destructive hurricanes on Earth, which can produce wind speeds of approximately 280 km/h.

So it means that if there were to be a great red 'jupiterian' spot on earth it would blow the earth away.

Answers

Answer:

photosynthesis

Explanation:

it takes carbon into the biosphere

Photosynthesis doesn't move carbon out of the biosphere instead takes up carbon  and uses it for energy production in plants. Therefore, option (B) is correct.

What is photosynthesis?

During the process of photosynthesis, plants draw carbon dioxide (CO2) and water (H2O) from the atmosphere and the soil respectively. Within the plant cell, water undergoes oxidation, which results in the loss of electrons, whereas carbon dioxide undergoes reduction, which results in the accumulation of electrons. Because of this, the water is converted into oxygen, and the carbon dioxide is converted into glucose.

Photosynthesis powers plant growth. This mechanism transforms carbon dioxide, water, and soil minerals into cells. Plants generate oxygen and nourishment.

Therefore, option (B) photosynthesis move carbon out of the atmosphere and into the biosphere.
