Sodium Chloride is placed in water, what happens to the sodium ions and chloride ions in the solution.
blondinia [14]
Na+ ion in sodium chloride is attracted to the oxygen side of the water molecules, while the Cl- ion is attracted to the hydrogens' side of the water molecule

this causes the sodium chloride to split in water, and the sodium chloride dissolves into separate Na+ and Cl- atoms

I think it's A?? B makes sense but the beginning of the paragraph is talking about how the royal society of science wasn't impressed, so it seems like the focus is on that and not how he defended against lightning strikes.

4 The graph below shows how the activity of an enzyme changes
choli [55]

Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

Arrange the following in the correct sequence, from earliest to most recent, in which these plant traits originated. 1. sporophy
zavuch27 [327]

Answer:

Earliest- gametophyte dominance, sporophyte dependence

Middle- sporophyte dominance, gametophyte independence

Recent-  sporophyte dominance, gametophyte dependence

Explanation:

The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores.  The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.

In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.
