Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

The population in a 50 square mile area is 200 people. What is the population density?
Answer:
[tex]\rho _{population}=4\frac{people}{mi^2}[/tex]
Explanation:
Hello.
In this case, since the population density is computed by dividing the amount of people by the space (area) where they are in:
[tex]\rho _{population}=\frac{people}{area}[/tex]
For 200 people living in a 50-mi² area, the population density is:
[tex]\rho _{population}=\frac{200people}{50mi^2}\\\\\rho _{population}=4\frac{people}{mi^2}[/tex]
It means that 4 people live per square mile area.
Best regards.

The diagram below shows the exchange of carbon dioxide (CO2) and oxygen (O2) between a cell and the blood flowing through a capillary.
In this diagram, the molecules of CO2 (represented by x’s) are moving from an area of--
Answer:
From an area of higher concentration to an area of lower concentration.
Explanation:
The molecules of CO2 are moving from an area of higher concentration to an area of lower concentration. Carbondioxide is produced as waste product in the cell during the process of respiration. This carbondioxide gas is loaded in blood cells because in the cell, concentration of carbondioxide gas is higher while on the other hand the concentration of carbondioxide is lower in the blood cells. This carbondioxide gas exchange in the lungs with oxygen which is required in the process of respiration for the production of energy in the form of ATP molecules. So from the conclusion we can say that CO2 moves from an area of higher concentration to lower concentration.

How does the experience of seeing a green leaf, connect with nuclear fusion in the Sun.
Answer:
The Sun shines because it is able to convert energy from gravity into light. This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion. Hope this helps

Is matchsticks biodegradable
Answer:
Unlike lighters, matches are made from wood or paper, which is easily biodegradable. Because they are biodegradable, they won't contribute to the growing waste problem in the world. The most common type of wood matches are made from aspen or white pine. Each tree can create hundreds of thousands of match sticks.

during photosynthesis, what is the source of the carbon i the sugar that is created
Answer:
Plants get the carbon from the air that humans exhale. They breath it in and use it for photosynthesis.
Explanation:
Took biology last year.
During photosynthesis, what is the source of the carbon is the sugar that is created is carbon dioxide in the air.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.Carbon dioxide serves as the source of carbon, and it enters the photosynthetic process in a series of reactions called the carbon-fixation reactions (also known as the dark reactions).Stages of photosynthesis:
(i) Absorption of light energy by chlorophyll.
(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
(iii) Reduction of carbon dioxide to carbohydrates.
