Answer:

pH meter and pH paper.

Explanation:

There are a few other ways that are commonly used, including titration, but most are tedious and require detailed hands-on work. A pH meter is normally assisted by the use of a computer or a digital user interface. The use of pH paper can be likened to the use of a Galileo thermometer.

Answer:

Similarities And Differences:

If a topic, law or scientific research shares the same origin of study, similar to another topic or term, then they will be compared and further analyzed by the team of scientists and research workers in order to have some conclusions and results.

Explanation:

As there are many scientific research and analyses which is been carried out in order to analyze the different elements in the process of comparison between any two subjects and terms.

There are various subjects and topics of research work. Many of the scientific research work are in parallel to each other as they are somehow compared by other scientists and research workers.

Assuming the stomata are open to the same degree, the rate of transpiration should _____ on a rainy day compared with a sunny da

Allushta [10]

Answer:

decline: decrease

Explanation:

Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.

On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.

Suppose you discover a new form of a nucleic acid, XNA. Like DNA, it is double-stranded. You are interested in its mode of repli

victus00 [196]

Answer:

A: Unlike DNA, XNA replicates conservatively

Explanation:

The replication of the DNA is semi conservative. This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.

In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.

Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
