DNA and RNA are two types of molecules that are responsible for the transfer of genetic information in living organisms. They are both made up of nucleotides, but they differ in their structure and function. In this article, we will explore the ways in which DNA and RNA are different.
DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid. DNA is found in the nucleus of cells, while RNA is found both in the nucleus and in the cytoplasm of cells.
The main difference between DNA and RNA is that DNA is double-stranded, while RNA is single-stranded. This means that DNA is composed of two strands of nucleotides that are held together by hydrogen bonds, while RNA is composed of a single strand of nucleotides.
Another difference between DNA and RNA is that DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. This difference in sugar structure affects the stability of the two molecules, with DNA being more stable than RNA.
DNA serves as the template for DNA replication, which is the process by which cells make copies of their DNA.

The amount of energy an area receives depends largely on A. Earths atmosphere B.The seasons C. The suns angle D.The suns distance from earth
Answer:
C. The sun's angle
Explanation:
The amount of energy received by an area depends on the suns angle from earth's surface.
Different areas of the earth receive different amounts of solar energy. As the earth revolves around the sun and the sun rays fall directly at the Equator, that makes areas lying at the equator are warmer while areas at the north and south poles receive minimum solar energy and remain colder.
Hence, the correct answer is " C. The sun's angle".

What makes a water molecule polar?
The pH of pure water varies with thetemperature.
A water molecule is made up of three atoms.
A water molecule has a slight charge on each end.
Water has the ability to be frozen.
Answer:
Therefore, water is said to be a "polar" molecule, which means that there is an uneven distribution of electron density. A hydrogen bond is a non-covalent bond between a partial negative charge and a partial positive charge. Hydrogen bonds tend to be weak. Hydrogen bonds tend to be transient.
Based on that, I would say that A water molecule has a slight charge on each end.
Explanation:
If I am correct, can I please have brainliest?
Answer:
[tex]\boxed {\tt C. \ A \ water \ molecule \ has \ a \ slight \ charge \ on \ each \ end}[/tex]
Explanation:
Water molecules are polar, which means the charge is not distributed evenly between the atoms.
The reason they are polar is the shape of molecule. Water molecules are bent and form a sort of "Mickey mouse" shape.
One water molecules= One oxygen atom and two hydrogen atoms bonded.The negative charge from the oxygen is on one end of the molecule, but the positive charge coming from the hydrogen is on the other end of the molecule.
The water molecule gets a different charge on each end, so the best answer is choice C.
what does it mean when you keep having a dream about a place but with different people in it?
Answer:
I have had many dreams like that. Where a different kind of dream takes place in the same setting.
I don’t think it has anything to do with parallel universes. Rather, the details of the place are what are important. In my case, it is two different houses. The rooms, the house itself, what I’m doing there, the condition of the rooms and the house — all these details are important to finding whatever meaning it has for me.

According to the concept of solubility,window cleaner is ammonia dissolved in water is an example of solution.
What is a solubility?
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

When Charles Darwin published his radical theory of evolution by natural selection in 1859 it was attacked by many early biologists as seriously flawed. Today his ideas are accepted as correct by biologists. From what we know of how science works, and the scientific method, why might opposition to Darwin's ideas disappear over the last 160 years?
Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.

A country that has been relatively poor is starting to become wealthier. This
has brought many people into the capital city, causing the population to grow
very rapidly. Many new apartment buildings, as well as water and waste
management systems, are being constructed to meet their living needs.
Which other technology would most directly help the survival of such an
expanding population?
A. Access to modern transportation systems
B. Building more parks and open spaces for recreation
C. A method for growing food with less available land
D. Using space in the city to build new landfills
Answer:
C
Explanation:
this is because for survival living things need a main 3 things and that's water, shelter and food. And if they can get it in limited space than that's just a bonus.
A method for growing food with less available land is the best method directly help the survival of such an expanding population, and it is the primary need, hence option C is correct.
How to maintain an expanding population in a country?When a country is starting to develop the population also needs to grow to live in that city, individuals who lived in other cities also moved to a developed country.
In developing countries, there is the basic need for food, is the primary requirement, and transportation and residency are the secondary things. To develop a method that produces a higher amount of food in less time and with available resources.
Therefore, a method for growing food with less available land is the need to survive for a growing population.
