Answer:yes
Explanation: when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.
Answer:
high
Explanation:
If the concentration of the water is low ten that means the solute-solvent ratio is high which means the solute(solid dissolved) is high

What is the function of DNA? It takes the message of the amino acid order for proteins to the cytoplasm, where the protein will be built. It serves as an enzyme to speed up many kinds of biochemical reactions in the cell. It builds proteins from amino acids using the instructions stored in RNA. It stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids.
Answer: The answer is B. (It stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids.)
Explanation: I took the test and this was the answer! :)
The function of DNA (deoxyribonucleic acid) is to store and transmit genetic information from one generation to the next, and it stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids. That is the last option.
What is DNA?DNA is a molecule composed of long chains of nucleotides. A nucleotide is made up of three components: a sugar molecule, a phosphate group, and a nitrogenous base. The process of gene expression begins with the transcription of DNA into RNA (ribonucleic acid). RNA is a molecule similar in structure to DNA but with a few key differences, such as the presence of the nitrogenous base uracil (U) instead of thymine. DNA also plays a role in the regulation of gene expression. Certain regions of DNA, called promoters and enhancers, help to control when and where a gene is expressed.
Hence, it stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids. That is the last option.

I will write essay, but need the 3 reasons why.
In this activity, you will need to analyze the reasons that people give for smoking. This may be done by interviewing some people you know that smoke or by going online and researching reasons persons give for smoking.
Below, in the downloadable essay, list three reasons why people smoke. Weigh each reason against the facts. In other words, prove that the reasons not to smoke far outweigh the reasons to smoke. Information on smoking can be found at the Centers for Disease Control and Prevention (CDC).
CDC Information on Smoking and Tobacco Use
1. Reason:
Opposing Argument/Contradictory Facts:
2. Reason:
Opposing Argument/Contradictory Facts:
3. Reason:
Opposing Argument/Contradictory Facts:
Answer:
Some reasons that people give for smoking:
> they believe it reduces stress and anxiety ( scientific studies show this isn't factual and the chemicals within smoking products is only made appealing and or distracting to make the user believe so. It actually heightens stress levels and lowers health levels)
> this sounds cliche but, teens often think its cool or get peer pressured into it. They find themselves wanting to try harmful substances and get addicted. ( in one study there were d r u g s found in smoking products aimed to get the attention of children and young adults. It's all a marketing ploy for business men and women to collect money as you slowly grow more and more breathless)
> lastly, "it's not that bad for you" often, markets and cig stores tell potential buyers its not as bad as other things. Some say its not harmful at all.( Lung disease,gum disease,heart failure,etc. all disprove this. Each year about 480,000 people die from the affects of smoking)

6)Twist your model and explain how it is a helix
7)Explain how Muslims can understand DNA from the Islamic Worldview
Answer:
DNA
DNADNADeoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
2) (i) A pentose sugar is a monosaccharide with 5 carbon atoms. Pentose sugars are the deoxyribose sugars, which are part of nucleotides in DNA
(Ii) a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H ₃PO ₄. The phosphate or orthophosphate ion [PO ₄]³⁻ is derived from phosphoric acid by the removal of three protons H⁺
Formula: PO₄³⁻
Molar mass: 94.9714 g/mol
3D model (JSmol): Interactive image; Interactive image; Interactive image; Interactive image
Beilstein Reference: 3903772
Conjugate acid: Monohydrogen phosphate
Gmelin Reference: 1997
(III) Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids.
3) purine nitrogenous bases:-
Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.
pyrimidine nitrogenous bases
Pyrimidine: A nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA.
The pyrimidine bases are thymine (5-methyl-2,4-dioxipyrimidine), cytosine (2-oxo-4-aminopyrimidine), and uracil (2,4-dioxoypyrimidine)
4) Explain Chargaff's rules for base -pairing
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C ) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
5)Identify what objects/colors you used for your DNA Model
The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
6)Twist your model and explain how it is a helix
Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.

In conditioning, during the sequence of delaying the stimulus, the dogs often displayed____ anxiety or excitement
In conditioning, during the sequence of delaying the stimulus, the dogs often displayed anticipatory anxiety or excitement. Therefore, the correct option is (C).
During the sequence of conditioning, as the stimulus is delayed, dogs often display anticipatory anxiety or excitement. This phenomenon is known as the "anticipatory response" and is a form of classical conditioning. The dogs have learned to associate the delayed stimulus (e.g., the sound of a bell) with the upcoming reward or punishment. As a result, they exhibit a conditioned response, expressing their anticipation of the outcome even before the actual stimulus is presented.This anticipatory response is a crucial aspect of classical conditioning, demonstrating the learned association between the conditioned stimulus (the bell) and the unconditioned stimulus (the reward or punishment). It reflects the dog's ability to predict the forthcoming event based on their prior experiences and conditioning history.Therefore, the correct option is (C).
