Monocots and dicots are two groups of _____.
Step2247 [10]
I believe the correct answer is the second option. Monocots and dicots are two groups of angiosperms. This group of plants are seed bearing plants. Flowers are their reproductive system where the ovules are being enclosed in the ovary. Angiosperms can be found in every habitat from grasslands and forests to deserts and sea margins. Angiospersms are divided to monocots and dicots. Monocot plants are characterized by having one cotyledon while dicots have two. Also, leaf veins of monocots are branched while that of dicots are parallel. The root system of monocots is a fibrous root system while dicots have a taproot system.

In an investigation, plant cells are placed in water that has been tinted blue. The investigators observe the color of the cells
larisa [96]

Answer:

C

Explanation:

When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.

If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.

In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.

Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.

Which is an example of scientific evidence that can be used to critique a new scientific argument?
Margaret [11]
When we perform a study, we test a specific hypothesis to see whether our hypothesis is supported by the data or not. If our hypothesis is not supported by the data, then we can argue that a specific argument (that would be important for this hypothesis) does not have a claim in scientific research. 

This is more broadly meant though. Usually you need to perform multiple studies and test multiple hypothesis to be able to critique a scientific argument and see whether the claims it makes and the predictions it makes hold up in scientific research.
