Analyze and Conclude 1. Evaluate How did the properties of the DNA you observed compare to those you
predicted in Pre-Lab Question 3?

2. Infer Why do you think that most DNA is stored in the nucleus of a cell and not
in the cytoplasm?

3. Use Analogies Sewing thread is very thin and difficult to see once a length of
thread is removed from its spool. How is the thread and spool an analogy for
what happened to the DNA in Step 7.

4. Draw Conclusions Water is the main ingredient in the detergent solution.
Ethanol is a type of alcohol. What can you conclude about the solubility of DNA
in water and alcohol?

5. Predict Do you think it would be easier or harder to extract DNA from animal
cells than from plant cells? Explain your answer?

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
