First of all, let's think about the scientific method, and its processes of how it works.
It all starts with observation, so we need to check all the data we have and all the information that can be collected to have a good thought on what's going on.
After gathering enough information, let's think about a hypothesis that could help solving this problem. Well, reading the question, we can check that that region passed through the wettest summer in 100 years, and that's the main problem here, because before this weather, was this disease a problem? I guess not, so this can be a reason, the change in the percentage of water in the air.
With that said, we need to test if this is true or not, and for that, we'll need mosquitoes with the West Nile virus, and we'll put them in different environments, one that it's wet, and another one that it's not that wet, just like the West Nile problem. This way we can check if this is the problem or not, if it's affecting their reproduction and etc.
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.
Answer:
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.
I hope this works and I helped :3
Explanation:
Answer:
Active transport proteins use adenosine triphosphate (ATP), the cell's energy storage molecule, to pump glucose into the cell, either with or against the concentration gradient.
