Air does rise and go up. For example, hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water. keep this in consideration though, as the hot air cools and sinks back to the surface of the earth, there it gets warmed by the ocean only to rise again. This is called a convection current. In conclusion, air does indeed rise and go up.

II. Abundance of resource
III. Inexpensive compared to other resources
A. I only
B.II only
C. I and II only
D. I, II, and III
Answer:
C. I and II only
Explanation:
i took the test and got it right
Photovoltaic cells and hydrogen fuels are inexpensive compared to other resources as well as they produce no pollutants to the surroundings. They components are abundant in nature as well. Hence all the options are correct.
What is photovoltaic cell ?A photovoltaic cell uses solar energy and converts the light energy to electrical energy. They are working with the principle of photoelectric effect. The solar energy is abundant to use and it is relatively less expensive to design the photovoltaic cells.
Fuel cells are using hydrogen as fuel. Hydrogen is abundant in the universe and is most efficient than all other fuels sources. Fuels cells involve the reaction of hydrogen and oxygen forming and water and not any other compounds are formed.
Both photovoltaic cells and hydrogen fuels are eco-friendly in the sense that they does not produce any pollutants to the atmosphere. Therefore, all the given are advantages of photovoltaic cells and hydrogen fuel.

What is the effect of paraquat on ATP, NADPH,
and sugar?
Answer:
ATP will increase
NADPH will decrease
Sugar will decrease
Explanation:
Trust, and I just got this answer
The effect of paraquat on ATP, NADPH, and sugar includes the fact that ATP will increase, NADPH will decrease, and sugar will reduce.
Paraquat is also referred to as methyl viologen. It's a toxic chemical which is used as an herbicide for grass and weed control.
Paraquat can cause damage to one's health when it comes into contact with one's mouth or intestines.
It should be noted that biochemical changes that are caused by paraquat in the lungs will lead to rapid and prolonged oxidation of the NADPH. This then leads to the reduction in NADPH as it attempts to detoxify the lipid hydroperoxides. Also, paraquat will lead to an increase in ATP and a reduction in sugar levels too.

How would you expect the spread of an airborne disease to be similar to and different from the spread of a foodborne disease and a person-to-person disease
Answer:
The airborne disease is only similar in the way that you must come in contact with infected air. There is no physical contact needed.
Explanation:
Answer: A. person to person
Explanation:
The graph shows that the disease spreads slowly at first, then rapidly, and slowly at the end. This pattern of transmission is most characteristic of a disease spread from one person to the next. When only one person has the disease, the rate of transmission is slow because that person may only meet a few others. But as the number of people with the disease increases, the number of meetings that spread the disease also increase. At this time, the disease can spread very rapidly. The disease spreads more slowly again when there are only a few people remaining that do not have the disease. With foodborne and airborne diseases, the rate of disease spread is most rapid when the disease first arises and the greatest number of possible victims are available. Graphs of foodborne and airborne transmission show the greatest rate of disease spread at the start of the outbreak.

A. Water is polar and oil is polar therefore the substances will not mix.
B. Water is nonpolar and oil is nonpolar therefore the substances won't mix.
C. Water is nonpolar and oil is polar therefore the substances will not mix.
D. Water is polar and oil is nonpolar therefore the substances will not mix.
Answer:
Water is polar and oil is nonpolar so the substances won't mix.
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.

Thermoses work because they minimize which kinds of heat transfer?
A.Conduction and convection
B. Conduction and radiation
С. Convection and radlation
D. Conduction, convection, and radiation
Answer:
B or C
Explanation:
I read about this awhile ago just forgot if it was ethier conduction or convection
The thermal heat energy transfers through various modes. Thermoses work because they minimize conduction and radiation transfer of heat. Thus, option B is correct.
What is heat transfer?Heat transfer has been the process that moves the heat from higher temperature towards the area of lower temperature. Conduction, convection, and radiations are the three modes of heat energy transfer.
In conduction, the heat flows from one body to another when they are in contact, and in radiation the heat flows in the waveform that does not need any direct contact. It needs an indirect medium to transfer the heat from high to lower temperatures. Thermoses do not show convection as it keeps the temperature constant.
Therefore, option B. thermoses use conduction and radiation.

Explain why the chemical equation for photosynthesis is a simplified representation of the process. How is the equation accurate? How is it inaccurate?
Answer:
The equation shows the general reactants and products of the process. However, it does not show intermediate steps. For example, carbon dioxide and water do not actually react with each other.
Explanation:
The equation is representing the general reactants and products of the process. But, it does not express the intermediate steps. For example, carbon dioxide and water do not actually react with each other.
What is photosynthesis reaction?The procedures by which chlorophyll bearing organisms and certain other microbes transforms sunlight to chemical energy is renowned as photosynthesis.
Light energy is grasped and utilized by green plants in the process of photosynthesis to efficiently convert, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Plants grab these carbon dioxide as well as water from either the environment or soil during photosynthesis.
Water is oxidized within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
The equation represents the process's broad sense reactants and products. It does not, however, convey the intermediate steps. Carbon dioxide and water, for example, don't really actually react with each other.
Thus, that's why the equation is perhaps not accurate.

Biodiversity allows for everything to exist. All types of animals, plants, etc. work and contribute in different ways, the actions that every species makes contribute to the larger ecosystem which allows for plants to grow, food to exist, other species to thrive, the atmosphere to exist, etc. All of these side effects create a system that allows Earth to maintain a habitable state and prevents it from becoming a dry and bare planet that cannot sustain life.

b. 46, 23, 23
c. 46, 12, 12
d. 46, 46, 46
Answer: B is the answer
Following mitosis, the daughter cells would each have a total of 46
chromosomes.
After meiosis I, the two daughter cells would have 23 chromosomes, and
after meiosis II it will still remain as 23 chromosomes.
Mitosis is a type of cell division that involves the production of identical
daughter cells. The daughter cells usually contain 46 chromosomes with all
the parent traits present.
Meiosis is a type of cell division which produces sex cells and for
reproduction. It involves generating unique daughter cells which is gotten by halving the 46 chromosomes to become 23 chromosomes.

HELP!What are the roles of and what happens to chromosomes, centrioles, centromeres, spindle fibers, nucleus and cell membrane during mitosis.
Answer:
Perhaps the most amazing thing about mitosis is its precision, a feature that has intrigued biologists since Walther Flemming first described chromosomes in the late 1800s (Paweletz, 2001). Although Flemming was able to correctly deduce the sequence of events in mitosis, this sequence could not be experimentally verified for several decades, until advances in light microscopy made it possible to observe chromosome movements in living cells. Researchers now know that mitosis is a highly regulated process involving hundreds of different cellular proteins. The dynamic nature of mitosis is best appreciated when this process is viewed in living cells.
