Can hydrogen peroxide be broken down by catalysts other than those found in a living system? What is/are the control(s) and why are they needed?

Answers

Answer:

Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. It is unstable which makes it very reactive. ... Sand however is not able to break it down

Explanation:

because it contains no catalytic properties

Manganese dioxide, which has catalytic properties, can degrade hydrogen peroxide. Because it is unstable, it is extremely reactive. It even degrades when exposed to light.

What is a catalyst?

A catalyst is a substance that accelerates or reduces the temperature or pressure required to initiate a chemical reaction without being consumed in the process. Catalysis is the process of facilitating a reaction by adding a catalyst.

Hydrogen peroxide is one of the cleanest and most versatile chemicals available, decomposing to produce only oxygen and water (disproportionation).

The catalytic decomposition of hydrogen peroxide allows for the use of various catalysts to speed up the decomposition process.

Another consideration is that catalase is an enzyme that degrades at higher temperatures. The activation energy of the reaction changes as the catalyst decomposes.

As a result, the reaction will slow down. Manganese dioxide, on the other hand, does not decompose even at higher temperatures.

Thus, it can be concluded that hydrogen peroxide be broken down by catalysts other than those found in a living system.

Answers

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

Answers

Answer:

D / D / D / B / C

Explanation:

I just took the quick check myself, got all of them right :)

1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.

2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.

3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.

4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.

5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.

1: It maintains other populations

2: A shark

3: The biodiversity of the area increases

4: Seasonal flooding does not impact biodiversity for as long term as damming.

5: Yes, because such a change could have a large-scale impact on wildlife.

what is digestion? Starting from mouth, state the various steps involved in digestion

Answers

Mouth. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.

Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.

Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.

Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.

Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.

Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.

Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement

Answer:

The gastrointestinal system starts in the mouth. In reality, as soon as you eat the first bite, digestion begins here. Chewing splits the meal into sections that are easier to eat, and saliva combines with food to start breaking down the body into a shape that you can consume and use.

Explanation:

The mechanism of digestion can be divided into various phases, such as mouth, stomach, small and large intestine.

A complicated mixture of mechanical and chemical processes are used in digestion. The mechanism includes food intake and push, mechanical or physical digestion, chemical digestion, absorption, and defeat.

1. What is the function of a top predator in an ecosystem?

A. It increases the food for other predator species.

B. It creates imbalance in the ecosystem.

C. It maintains populations. **

D. It helps increase the number of prey.

Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.

2. Which is considered a top predator in the ocean?

A. A shark**

B. A sea lion

C. A small whale

D. A bird.

Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)

3. What happens to an ecosystem during normal seasonal flooding?

A. The biodiversity of the area reaches equilibrium.

B. The biodiversity of the area increases. **

C. The biodiversity of the area decreases.

D. The biodiversity of the area stays the same.

Reason - Just trust, I'm trying to finish this post and got tired of giving reasons. Sorry and thanks:)

4. How is the impact of seasonal flooding different from damming a river?

A. Seasonal flooding helps balance biodiversity, but damming does not.

B. Seasonal flooding is not considered an ecological disturbance like damming.

C. Seasonal flooding does not impact biodiversity for as long term as damming.**

D. Seasonal flooding increases biodiversity, but damming does not.

Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)

5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?

A. No, because it would not create large-scale changes in the environment.

B. No, because increases and decreases in average temperatures are normal.

C. Yes, because such a change could have a large-scale impact on wildlife. **

D. Yes, because any slight change in temperature is considered a distribution.

Explanation:

The second student set up solutions that were in equilibrium.

On which principle Dialysis is based?

Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.

In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing  molecules of water to diffuse across the membrane along the concentration gradient.

Therefore, the second student set up solutions that were in equilibrium.
