Explanation:

polarity can mean different things based on how you use it but in chemical bonding its the distribution of the electric charge over the atoms in the bond and in chemistry its typically physical properties such as melting and freezing point but like i said it depends on how its used

The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".

A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

Explanation:

1) antibiotic drugs can kill bacteria however, they are not effective against viruses

2) some bacteria's help to digest foods and speed up enzyme reactions. Some bacteria cells destroy disease causing cells

The treatment for viral and bacterial illnesses differs primarily due to the fundamental differences in their nature and characteristics. Bacteria are living organisms that can be targeted by antibiotics, whereas antiviral medications are used to treat viral infections.

Both bacteria and viruses can affect healthy body cells, with bacteria directly invading cells and causing damage, while viruses rely on host cells for replication and can induce damage during the process.

Bacteria and viruses can both cause damage to host cells. Bacteria can directly invade and damage cells through mechanisms such as releasing toxins or inducing inflammation.

Viruses require host cells to reproduce. They invade host cells, hijack cellular machinery to replicate themselves, and subsequently cause damage to the infected cells during the process.

Answer:

The Correct answer is DNA is transcribed into RNA which is translated into protein

Explanation:

The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

The model of the Human digestive system that is most detailed is ( B ) : Dissected Pig

Pigs and Human have similar internal organs and the locations of each organ in both mammals are similar as well, therefore from the options the closest model that is most detailed as regards to the Human digestive system is a dissected pig.

A photograph of the digestive system does not provide a detailed model, also an artist drawing cannot provide as much detail as needed.  A 2d computer-generated model will only present the digestive system in 2 dimensions hence it is not detailed enough as well.

Hence the most detailed model is a Dissected pig model.

The phrase which best describes air pressure is: decreases as a result of fewer air particles pushing down.

Pressure can be defined as a measure of the force exerted per unit area of an object or physical body. Thus, it is usually measured in Newton per meter square and calculated by using this formula:

[tex]P = \frac{F}{A}[/tex]

Where:

In Science, there are different types of pressure and these include the following:
