Autoclaving is the most effective among all moist heat-related antimicrobial methods. (True or False)

Biology
1 answer:
kirza4 [7]2 years ago
4 0

Answer:

True.

Explanation:

Autoclaving is the most effective among all moist heat-related antimicrobial methods because this method can kill all the harmful microbes such as bacteria, fungi and viruses. Moist heat causes destruction of microorganisms by denaturation of macromolecules that is present in their body such as proteins. Autoclaving is a very common method for moist sterilization. It is an effective method in killing fungi, bacteria, spores, and viruses but it does not eliminate prions.

Why are protozoa significant? Select all that apply. Protozoa contaminate the water supply. Protozoa do not contribute to a food
Luba_88 [7]

Answer: Protozoa contaminate the water supply.

Some protozoa are parasites and cause diseases like malaria.

Protozoa have an important role in the food chain.

Protozoa are parasitic or free living single celled eukaryotic organisms. They are mostly found in water bodies.

Protozoa contaminate the water supply: Some of the protozoan species which are released from the human feces usually contaminate thee water, and causes waterborne infections in humans. Examples are Cryptosporium and Giardia. The infection occurs through drinking water or swallowing water from swimming pool.

Some protozoa are parasites and cause diseases like malaria: The Plasmodium is the genus belonging to the protozoan parasites. This malarial parasite is transmitted by female Anopheles mosquitoes to humans. The parasite multiply in the red blood cells causes symptoms like fever, anemia, flue, illness and may also cause coma and death.

Protozoa have an important role in the food chain: The protozoa species plays many roles in the food chain, they act as consumers, predators or prey, herbivores and decomposers. Their main function is to control the population of other species in the same habitat. They engulf small single celled bacteria, hence prevents excessive bacterial colonization act as predator. They also feed upon the algal species therefore, act as herbivores. They act as decomposers, as they feed upon the organic matter present in the bottom of the aquatic water body. They are the source of food for large worm and insect species.

The sole of a gecko's foot is covered with millions and millions of small, dry "hairs" that make direct contact with surfaces, a
tamaranim1 [39]

Answer: Van der Waals forces

Explanation:

Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.

The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.

Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.

Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
