The cell will increase in size as the water concentration increases due to osmosis. This means the cell fills up with more water which will cause it to expand. And if this is a plant cell then it will cause it to become turgid and the cell contents push against the cell wall.

maria [59]

Answer:1.c 2.d 3. d

Explanation:

The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.

The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.

What is the same about the electronic structures of lithium and sodium?
Sedaia [141]

Answer:

Sodium and lithium are in the same group of the periodic table; this is because they both have the same number of electrons in their outer shell (1 as indicted by the group number). this commonality is the reason they have similar chemical properties. As we go down the group however, the electronic structure of atoms of an element changes as that there are a increasing numbers of ‘shells’.

Electron ‘shells’ are filled according to ruled of quantum mechanics however to simplify things in this case the first shell can fit 2 electron, the second 8, and the third shell 8. Lithium has 3 electrons, hence it the first shell is filled, and 1 electron occupies the second shell. Whilst Sodium has 11 electrons, hence its first two shells are filled and the third shell is occupied by one electron.

To expand on this question, the duet/octet rule is a rule in quantum mechanics that observes that main group elements tend to be stable with a full outer shell.

This explains why sodium and lithium is found in the form of Li+ and Na+ ions in nature.

Scientific method lab results
-Dominant- [34]

Answer:

1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.

2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.

3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).

4.Establish a theory based on repeated verification of the results.
