The answer is B only because it makes wayyy more sense
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:
The circulatory system
Explanation:
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH,
Answer: The observation clearly shows that certain behaviors are genetically controlled
Explanation:
From the observation, the Fishers bird uses long strip while the Peach-faced uses short strips and there offspring uses intermediate. It is an indication that the behavior of the length of strips cut by the bird is under genetic control and it can also be concluded that both the Fisher bird or Peach-face bird does not have complete dominance over length of strips cut for nest making.
