Answer:
- The solution is hyperosmotic to the body.
- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L
- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L
- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased
- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.
Explanation:
A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).

discuss the contributions of pasteur, and koch to 'germ theory of disease' and to the prevention of diseases
Answer:
Pasteur showed that putrefaction is a process associated with organisms present in the air, while Koch identified the germs that cause different diseases
Explanation:
The germ theory states that pathogenic microorganisms called germs cause the disease state observed in a particular (infected) organism. The term 'germ' includes pathogenic bacteria, protists, fungi, and even non-living pathogens (e.g., viruses). This theory was developed and accepted due to the work of Louis Pasteur and Robert Koch. In the 1860s, Pasteur showed that germs were omnipresent in a flask open to the air, showing that putrefaction and fermentation are caused by these microorganisms. Moreover, in the 1880s, Koch identified the germs that cause different diseases, including tuberculosis (Mycobacterium tuberculosis) and cholera (Vibrio cholerae).

Explain how stem cell therapy helped Lucy break down deoxyadenosine
Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.

Storm water runoff carries pollution
Answer:
Precipitation is increasing in deserts due to an increase in water use
Explanation:
Just see for yourself
The one that is not a human effect on the water cycle is precipitation is increasing in deserts due to an increase in water use. The correct option is B.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
One of the most essential elements of human life is water. There is water all over. It passes through your house as well as rivers, mountains, lakes, and oceans. Without water, neither humans nor any other species could survive.
In the majority of deserts, the air's moisture content is very low. In the dry air, light raindrops frequently evaporate before they can reach the ground. Rainstorms can occasionally appear as ferocious cloudbursts.
Therefore, the correct option is B. Precipitation is increasing in deserts due to an increase in water use.

B.Gametes are formed with the same number of chromosomes as the parent cells
C.Offspring display half of their traits from their mother and half of their traits from their father
D.Offspring have traits not displayed by either parent
Answer:
c option is correct.
Explanation:
gametes are produced by meiosis during which genes get crossed in a process of crossing over ad new recombinent characters are produces. these gametes fertilized and offsprigs have multiple characters they get from their mother and faaher. so offsprimgs have characters half from mother and other half from father.
Genes often produce gametes. The statement that describes a possible result of this process is that Offspring display half of their traits from their mother and half of their traits from their father.
What is genes and gametes?A gene is known to be the molecular unit of heredity of all living beings.
A gamete is known to be a cell that comes together with another cell during fertilization that takes place in organisms that reproduce and this is a product of the male and the female gamete.

Please :( Based on your knowledge of evolution, are humans evolving? Support your answer with factual evidence as to
why or why not
Answer:
Jesus made every one evalution is false
When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.
The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:
