Population density is calculated by _______.

Answers

Population density is calculated by dividing the total population of a specific area by the total land area of that area.

The formula for population density is:

Population density = Total population / Total land area

To calculate population density, you need to know the total population and the total land area of the area you are studying. For example, let's say we want to calculate the population density of a city with a population of 500,000 people and a land area of 100 square kilometers.

Using the formula, we can calculate the population density as follows:

Population density = 500,000 / 100 = 5,000 people per square kilometer

This means that in the city we are studying, there are approximately 5,000 people living in each square kilometer of land.

Population density is an important measure that helps us understand how crowded or sparse a particular area is in terms of population. It is often used to compare different regions or to analyze population trends over time. By calculating population density, we can gain insights into the distribution of people and understand the impact of population growth on a specific area.

What accounts for water's properties of adhesion and cohesion?

Answers

What accounts for water's properties of adhesion and cohesion? The polar nature of water and the effects of hydrogen bonding

Further explanation

Adhesion is the tendency of dissimilar particles to cling to one another. While the cohesion is the grammatical and lexical linking within a sentence that holds the text together and gives the meaning. Cohesive forces are the intermolecular forces which cause a tendency in liquids to resist separation. The example of intermolecular forces  are hydrogen bonding and Van der Waals forces. The differences between adhesion and cohesion are in adhesion, the molecules of different substances stick together and in cohesion, the molecules stick to each other

Water is a transparent, tasteless, odorless, and nearly colorless chemical substance. There are five main properties of water such as:

  1. The attraction to polar molecules.
  2. High-specific heat.
  3. High heat of vaporization.
  4. The lower density of ice.
  5. High polarity.

The bonding between the hydrogen atom and the polar nature of the water account for adhesion and cohesion characteristics of water.

Further Explanation:

The water molecules have two hydrogen atoms attached to an oxygen atom by a polar covalent bond. Carbon has an electronegativity of 2.55, which is very close to the electronegativity of hydrogen (2.20). Water is a good solvent because it is a polar molecule (polarity of a molecule is the separation of electric charge result to a molecule consisting of an “electric dipole moment” through a positively charged end and negatively charged end). The oxygen atom in the water molecule is more electronegative (tendency to attract electrons, as they are electron deficient.), while hydrogen molecule is electropositive as compared to the oxygen.

Due to this electronegativity difference, the shared pair of electrons is prominently pulled towards the oxygen atom, giving the atom a partially negative charge, and the hydrogen atoms a partially positive charge. The polarity of water is accountable for the “cohesion and adhesion” characteristics of water.

Penicillium notatum is what type of organism?

Answers

Penicillium notatum is  a fungi.
Penicillium is a genus of ascomycetous fungi which has a major importance in the natural environmen. It plays an important role in food and drug production as well. Some members of the said genus produce penicillin, a molecule that is used as an antibiotic. These antibiotics kill or stop the growth of certain kinds of bacteria inside the body.
