Answers
Answer: B, C, and D.
Explanation: Leaves absorb the light coming from the sun. Leaves also have something included in them called chlorophyll. Plants use this chlorophyll and light for photosynthesis. The stem helps to transport the products of photosynthesis. The roots absorb some of the most important nutrients to a plant.
Three organs that help a plant carry out photosynthesis are the leaves, by trap sunlight and take in carbon dioxide, and the stem, which transports nutrients and water to plant cells.
What is photosynthesis?Photosynthesis is a chemical process by organisms that contain chlorophyll to make their own food. The process includes light, carbon dioxide, water, and chlorophyll.
Thus, the correct options are B and C.

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
Answers
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.

Which statement best describes a dormant plant? *
1.It is in need of food,
2.It is hardy
3.It is inactive
4.It is fast growing
Answers
Explanation:
Dormant plants are plants that are able to endure and survive in such harsh conditions. Looking at the definition of “Hardy” it is indeed the correct answer.
Also If you wanted, you could use process of elimination to answer this question.
1. It is in need of food.
While this may be half true, it isn’t fully correct because most dormant plants have waxy covered leaves, or some storage function to save water. That allows them to survive.
2. It is hardy.
This is true because dormant plants are very strong plants for being able to survive in such harsh conditions. That being said this answer is most likely correct.
3. It is inactive.
Dormant plants are kind of like hibernating bears because they store and collect to survive but there is one difference and it’s that bears go to sleep and are inactive while these plants remain active.
4. It is fast growing.
This is kind of hard to answer but there is one thing that makes this answer not correct and it’s that this doesn’t correlate to the original question. What does a dormant plant have to do with fast growing?
Looking at all these answer choices, we have managed to find the (hopefully/most likely) correct answer.
I hope this helped you! :)
9. In one or two sentences, describe how the available energy may affect the population sizes of organisms at different
trophic levels
Answers
Answer:
Explanation:
In food web energy are been transfered from the producer which are often plants down to the last individual on the web.
Each individual takes in and expels the remaining to the next until it is distributed to all. The amount of energy received from the producer will determine the amount of energy that will be available for others to share, when enough energy is transferred they all have enough to share but when the energy level is low the individual on the web also receive a low energy this may affect the population leading to a reduction,
It can also lead to competition among the organisms,migration out of environment to search for food. But When the energy level is high or on the increase it leads to growth and development among the organism.
Why can't the air just rise and go up?
it's sinking
it's spinning
Answers
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.

What is the effect of paraquat on ATP, NADPH,
and sugar?
Answers
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.

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.

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.

Answers
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.

Pathogens: These are invading the bloodstream, so you can see them among the white cells, and too many of them. Macrophages are one of the different types of white globules involved in the organism's defense against strange substances and pathogen agents. These cells are the principal actors in the immune response. Macrophages are the principal phagocytes of tissues, capable of recognizing different strange molecules that penetrate the organism, such as bacterias, parasites, and viruses. Macrophages phagocyte these substances and eliminate them, a process known as phagocytosis. Macrophages also have the capability of inducing an adaptative immune response. Macrophages show the antigens on their surfaces where they are recognized by lymphocytes.Helper T-cell: T-Lymphocytes are in charge of the regulation of the immune system. T-cells are the helper cells that coordinate the initial response in front of the pathogen. There are three types of helper T-cells: TH1 (lymphocyte T helper), TH2, and TH17.

The three components of RNA are a phosphate group, ribose sugar, and a nitrogenous base
How are the base pairs different?
Answers
Answer:
The nitrogenous bases Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.
Explanation:
Nucleotides are monomers that make up DNA and RNA- these are nucleic acids that function as storage, transport and messenger molecules for encoding proteins. Nucleotides contain a 5-carbon deoxyribose (with hydroxyl modifications) or ribose sugar (RNA), phosphate and one of four nitrogenous bases:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).- DNA only
Uracil (U) found in RNA
Nucleotide monomers derive their names from their bases. Nucleic acid polymers form on a single strand through covalent bonding. This occurs between two nucleotides in an esterification reaction where a phosphodiester bond is formed.
Nitrogenous bases encourage hydrogen bonding, and resulting base pair formation. Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.

HELP!What are the roles of and what happens to chromosomes, centrioles, centromeres, spindle fibers, nucleus and cell membrane during mitosis.
Answers
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.
