Answer:
O As the air around the campfire is heated and becomes less dense, it rises and moves upward.
Explanation:
This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.
Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.
What is convection of heat?Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.
The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.
Therefore, the correct option is C.

Answer options:
The DNA located in the nucleus of the cell The cell in which the protein is located The amount of ATP available for the cell’s use The area in a cell where proteins are producedAnswer:
The DNA located in the nucleus of the cell
Explanation:
The sequence of the DNA is transcribed into a messenger RNA (mRNA). The mRNA molecule is translated into a sequence of amino acids. Every 3 nucleotides in the mRNA represents a codon. These codons correspond to a complementary anticodon linked to a tRNA, which specifies the order of amino acids in a protein.

Fats are the predominant forms of a class of biological molecules called _______, which also includes fatty acids and steroids, among other molecules. These biomolecules readily dissolve in _______ solvents such as hexane and chloroform. Because of their insolubility in water, fats and other biomolecules in this class are said to be_______. Triacylglycerols, also known as triglycerides, are a storage form of fat found in adipose tissue that consist of glycerol bound to_______. These fats are categorized based on the bonding of the carbon atoms in the chain. Fats that contain chains with no double bonds are classified as_______ , whereas those that contain double bonds in the carbon chain are _______.
Answer:
1. Lipids
2. Non-polar
3. Non-polar
4. Fatty acids
5. Saturated fats
6. Unsaturated fats
Explanation:
LIPIDS are one of the four major biomolecules in living systems. A form of lipids are fats which constitute most lipids i.e. predominant. Lipids also includes fatty acids, steroids and other molecules.
Lipid biomolecules readily dissolve in POLAR solvents such as hexane and chloroform. Because of their insolubility in water (polar solvent), fats and other biomolecules in this class are said to be NON-POLAR.
Triacylglycerols, also known as triglycerides, are forms of fat that is composed of a glycerol molecule bound to three molecules of FATTY ACIDS.
Based on the bonding of the carbon atoms in the chain, fats that contain chains with no double bonds are classified SATURATED FATS, while those that contain double bonds in the carbon chain are UNSATURATED FATS.

When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?
Answer:
The new solution has a higher concentration than the isotonic saline solution
Explanation:
Here, we want to deduce what has happened in the question.
We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.
Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.
What has occurred is the process of Osmosis
Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.
So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

1. Form hypothesis: How does temperature affect oxygen concentrations?
If you're correct then I'll give you brainliest! c:
Answer:
Hello!!! Princess Sakura here ^^
Explanation:
First things first if we are going to form a hypothesis it doesn't matter if it is correct hypothesis are supposed to get tested.
So anyways....
I believe that the solubility of oxygen will decrease as the temperature increase.
I believed that because as temperature increases molecules start to move faster and move farther away from each other.
Temperature can have a significant impact on the concentration of oxygen in various environments. 1) Solubility of Gases, Oxygen Dissociation, Biological Processes.
Here's a step-by-step explanation of how temperature affects oxygen concentrations:
1. Solubility of Gases: The solubility of gases, including oxygen, in a liquid like water is affected by temperature. Generally, as temperature increases, the solubility of gases decreases. This means that at higher temperatures, less oxygen can dissolve in water or any other liquid.
2. Oxygen Dissociation: In the context of the human body, temperature affects the dissociation of oxygen from hemoglobin in red blood cells. As temperature increases, the affinity between oxygen and hemoglobin decreases. This means that oxygen is more readily released from hemoglobin and made available to tissues and organs. Conversely, as temperature decreases, the affinity between oxygen and hemoglobin increases, making it more difficult for oxygen to be released.
3. Biological Processes: Temperature also affects the metabolic rates of organisms. Generally, as temperature increases, metabolic rates increase, leading to higher oxygen consumption. For example, in aquatic ecosystems, warmer water temperatures can enhance metabolic rates of aquatic organisms, leading to increased oxygen demand. Conversely, lower temperatures can slow down metabolic rates and reduce oxygen demand.
It's important to note that the specific effects of temperature on oxygen concentrations can vary depending on the system or environment being studied. Different factors such as pressure, salinity, and the presence of other substances can also influence the relationship between temperature and oxygen concentrations.
