It adds bulk to our stools.

It helps food to move through your digestive tract more quickly for healthy elimination.

Fibre helps prevent diseases, diabetes, heart disease, weight gain and cancers. It also helps with stool
hope that helps:)

What are the different types of limiting factors found in nature?

disa [49]

1. the availability of food, water, shelter and space.

2. Common limiting factor resources are environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem. The limiting factor also causes competition between individuals of a species population.

Example: Space, food, or water.

3. Limiting factors, such as food, would sometimes cause one organism to kill another to survive or fight over that factor. But with space, it would get crowded probably.

4. ( i couldn't find anything about South America Ecosystems Interactive... sorry )

5. "Native people" are ethnic groups who are the original inhabitants or descendants of the original people.

Example: the Yanomami and the Tupi People of the Amazon.

6. I would say do an experiment or something???

7. A variable is any factor, trait, or condition that can exist in differing amounts or types.

8. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The dependent variable is also called the outcome variable.

9. A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.

Example: when testing for a new pill, one group is given the pill to see affects, one group (the control group) is given a placebo and is used to see what happens when given a placebo.

10. Changes in limiting factors will cause a population to decrease.

11. They are transmitted from indirect contact usually.

12. An animal or plant on or in which a parasite or commensal organism lives.

Example: When a human doesn't wash his/her hands and that makes someone else sick. Another one is since humans naturally have bacteria, some are bad and can cause a virus.

13. An infectious agent is something that infiltrates another living thing.

14. Lack of membrane-bound organelles, unicellular, and small.

15. cocci, bacilli, and spirilla.

16. Viruses can replicate only by infecting a host cell and they cannot reproduce on their own.

17. Influenza, HPV, and rabies.

18. Any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter.

Example: Pink waxcap, coral tooth, and pig's ear. (this is not their scientific name haha)

I hope this helps :D

Identify an example organism for each type of cellular respiration: aerobic respiration, anaerobic respiration, and fermentation

Julli [10]

Answer:

Anaerobic respiration-" The process by which cells that do not breathe oxygen liberate energy from fuel to power their life functions."

These organisms also use an electron transport chain to generate as much ATP as possible from their fuel, but their electron transport chains extract less energy than those of aerobic respiration because their electron acceptors are weaker. The Staphylococcus aureus and Lactococcus lactis are two organism which performs anaerobic respiration.

Aerobic respiration-"The process by which oxygen-breathing creatures turn fuel, such as fats and sugars, into energy."

Organisms who performs aerobic respiration:

Most of the living beings humans etc.

Fermentation:"The metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain."

Mechanism-" The main porpuse is to convert NADH back into the coenzyme NAD⁺ so that it can be used again for glycolysis."

During fermentation, an organic electron acceptor reacts with NADH to form NAD⁺, generating products such as carbon dioxide and ethanol or lactate in the process.

Types-

Ethanol fermentation,
Lactic acid fermentation.

Explanation:

Difference between Aerobic and anaerobic respiration:

In anaerobic cells, however, respiration typically takes place in the cell’s cytoplasm, since most anaerobic cells do not have specialized organelles.
In aerobic cells, the electron transport chain, and most of the chemical reactions of respiration, occur in the mitochondria.

Steps of Aerobic Respiration:

1. Glycolysis. In aerobic cells, the equation for glycolysis is:

Glucose + 2 HPO₄²⁻- + 2 ADP³⁻ + 2 NAD⁺ → 2 Pyruvate⁻ + 2 ATP⁴⁻-+ 2 NADH + 2 H⁺ + 2 H₂O,

2. Oxidative decarboxylation of pyruvate

2 (Pyruvate⁻ + Coenzyme A + NAD⁺ → Acetyl CoA + CO₂ + NADH),

3. Citric acid cycle

2 (Acetyl CoA + 3 NAD⁺ + FAD + GDP³⁻ + HPO₄²⁻ + 2H₂O → 2 CO₂ + 3 NADH + FADH₂ + GTP⁴⁻ + 2H⁺ + Coenzyme A),

4. Oxidative phosphorylation

34 (ADP³⁻ + HPO₄²⁻ + NADH + 1/2 O₂ + 2H+ → ATP⁴⁻ + NAD⁺ + 2 H₂O)

Electron Transport Chain Steps- These four complexes actively transfer electrons from an organic metabolite, such as glucose. When the metabolite breaks down, two electrons and a hydrogen ion are released and then picked up by the co-enzyme NAD+ to become NADH, releasing a hydrogen ion into the cytosol.

Complex I: The complex-structured proteins embedded in the phospho-lipid membrane.
Continuing onto Complex II,
Traversed to Complex III,
Cytochrome c via co-enzyme Q,
And then finally to Complex IV.

Note-By-products from other cycles and processes, like the citric acid cycle, amino acid oxidation, and fatty acid oxidation, are used in the electron transport chain. As seen in the overall redox reaction,
