What is the defining characteristic of an acid?
Answer:
Acid in chemistry has distinguishing properties as a substance. Acidic compounds are acidic; they react with paper, bases and metals; they conduct electricity; they have a pH of less than 7. They can generate electricity. Based on reactivity, conductivity and pH levels, an acid can be categorized as strong or weak.
Explanation:
The defining characteristic of an acid is when dissolved in water, acids are sour in taste, conduct electricity and react with metals to produce hydrogen gas.
What is an acid?
"An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis)."
What are the types of acid?
Usually acids can be divided into three major types:
binary acid, oxyacid, carboxylic acid.What are main characteristics of acid?
The main characteristics of acid are:
Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current.Acids have a sour taste.Acids change the color of certain acid-base indicates.

11. The Human Genome Project showed that humans have around
thousand genes;
about as much as a
and twice as many as a
Answer:
The answer isn't on there, but humans have estimated 20,000-30,000 genes.
The closest answer in the selection is "Twice as many as A"
Explanation:
The HGP has revealed that there are probably about 20,500 human genes. This ultimate product of the HGP has given the world a resource of detailed information about the structure, organization and function of the complete set of human genes.
Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins. Each of the estimated 30,000 genes in the human genome makes an average of three proteins.
According to the latest estimate, humans only have twice as many genes as worms or flies. On average, humans have 20,000–30,000 genes.
What is genome?Genome is defined as the entirety of a cell's DNA instructions. The genome's main job is to preserve, express, and store the genetic material that gives rise to a cell's structural and functional machinery. The genome is a significant part of the cell's structural makeup, nevertheless. It gives the organism all the knowledge it needs to function.
Aiming to better our comprehension of the genetic contribution to human health and disease, the 1000 Genomes Project is an international research cooperative that was established in 2007. Its goal is to sequence the genomes of at least 1,000 volunteers from various communities around the world. The human genome's gene index analysis places the number of genes at around 120,000.
Thus, according to the latest estimate, humans only have twice as many genes as worms or flies. On average, humans have 20,000–30,000 genes.

1.what effect does air pressure have on wind movement?
2.what happens to the density of air as it is heated
3. It’s a hot, sunny morning in a coastal town in south Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer: 1) Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience. 2) So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.
Explanation: 3) Now that there are large puffy clouds in the area, most of sunlight will be clocked from reaching the earth's surface. The land will cool faster than the ocean (because water has a high heat capacity and has to lose more energy to drop by a degree which will take longer than land).
Explanation:
1)Air pressure drives the creation of wind worldwide. Although it is not the only factor, differences in air pressure throughout the Earth's atmosphere lead directly to wind and influence the speed and direction of that wind. Pressure differences also affect larger weather systems like storms, even hurricanes.
2)
Heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons. The air is heated by the burner and the expanding air becomes less dense, causing the balloon to rise through the denser, cooler surrounding air.
In which of the following ways is DNA replication different from DNA transcription? (4 points)
New cells can be created only after transcription has taken place.
Replication results in mRNA strands, while transcription creates new DNA.
Transcription happens outside the nucleus, and replication happens inside the nucleus.
Thymine is used in replication, while uracil is used in transcription.
Answer:
Transcription copies the DNA into RNA, while replication makes another copy of DNA. Both processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in gene expression and the other involved in cell division.Explanation:
So,my answer is,transcription happens outside the nucleus,and replication happens inside the nucleus.

A. Red blood cells have different genes than skin cells
B. Red blood cell produce DNA, but skin cells do not.
C. Different genes are activated in blood cells compared to skin cells
D. Blood cells have recombinant DNA
Answer:
A. Red blood cells have different genes than skin cells
Explanation:
This specialization takes place because, the red blood cells have different genes than the skin cells.
Red blood cells have different genes than skin cells. Therefore, option A is correct.
What is hemoglobin?Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body. Hemoglobin can be thought of as the iron-containing, oxygen-transporting protein found in red blood cells. The color of red blood cells is also due to hemoglobin.
You have a low red blood cell count if a hemoglobin test finds that your hemoglobin level is lower than normal (anemia). Numerous factors, such as vitamin shortages, bleeding, and chronic illnesses, can contribute to anemia.
Skin cells do not produce hemoglobin because they have different genes than red blood cells. Therefore, option A is correct.

Occasionally cells stop dividing and enter another phase, G. If you damage your liver, new
liver cells can be produced to replace up to 75% of the liver. However, if you sustain brain
damage, your body does not produce new brain cells. Explain this observation using what
you have learned about the cell cycle. Hint: What phase of the cell cycle are the brain cells
in once they mature?
The phase of the cell cycle are the brain cells in once they mature is G0 phase (inactive phase).
What happens in the G0 period?The G₀ phase is the phase of the cell cycle where the cell remains in interphase indefinitely. Generally, highly specialized cells such as nerve cells are found in G0. Depending on the type of cell, stimulation and the return of the cell cycle can occur.
It is important to mention that there are cells that do not divide and that, for this reason, do not pass to the later phase, S. When this happens, the cell remains in a phase called G0.
These cells that do not divide further exist G1 phase to enter an inactive stage called quiescent stage (G0) of the cell cycle.
