I'm pretty sure it's high density as a solid.

Answer: Option (c) is the correct answer.

Explanation:

Vapor pressure is defined as the pressure that is in contact with its liquid or solid form.

Whereas boiling point is defined as the temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure.

When a substance has high boiling point then it means there will be less formation of vapors. Hence, it will have low vapor pressure.

For example, boiling point of water is 100 degree celsius and it is a high temperature. Therefore, vapor pressure of water is low.

This means that at 100 degree celsius or below 100 degree celsius water exists in liquid state.

Hence, it is able to allow large bodies of liquid to exist on Earth.

Whereas when water is present in solid state that is, ice then due to less density of ice it has the ability to float of liquid water.

Also, heat capacity of water is 4.18 $J/K ^{o}C$ which is also high.

Thus, we can conclude that low vapor pressure is the property of water allows large bodies of liquid water to exist on Earth.

When a population is at Hardy-Weinberg equilibrium which one of the following is true?

uysha [10]

Answer:

The correct answer will be option-D

Explanation:

The Hardy-Weinberg principle was given by two different scientists Godfrey Hardy and the Wilhelm Weinberg which worked on understanding the population genetics.

The Hardy- Weinberg equilibrium is based on certain assumptions like population should have no mutations, no emigration, no selective pressure, no migration and the population should be infinite.

Since the Hardy- Weinberg equilibrium is widely used to determine the allelic frequency from the genotype therefore option-D is the correct answer.

Some bacterial pathogens are highly infectious via the respiratory route. Determining whether the pathogen can make an enzyme th

aleksandrvk [35]

Answer:

Explanation:

Escherichia coli, is a type of bacteria that lives in the intestines. It's also found in the gut of some animals. Most of them are harmless, they aid keeping the digestive tract healthy. Though if contaminated food or fouled water is consumed, some strains can cause diarrhea .

Catalase enzymes, hydroperoxidase I (HPI) and HPII, catalyze the dismutation of hydrogen peroxide to water and oxygen but they play crucial roles in protecting cells against the effects of oxidative stress.

Some examples of pathogenic microorganisms which produces catalase include staph, bacillus, aureus,etc

Test Procedure:

With the aid of a loop or sterile wooden stick, a small amount of bacterial colony should transferred onto the surface of clean, dry glass slide .

A drop of 3% Hydrogen peroxide should be placed on to the slide and mixed.

A positive result is indicated by the rapid evolution of oxygen gas (within 5-10 seconds), which is evident by bubbling, while a negative produces no bubbles or only a few scattered bubbles.

The used slide should be disposed in the bio hazard glass disposal container.

Do stems anchor plants into the earth and draw water and nutrients from the soil?

Julli [10]

Answer:

The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves.
