Answer:
1. True
- Those are compounds
2. False
-They are actually polar molecules
3. True
-Acids are molecules that give away a type of subatomic particle
4. False
-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.
5. False
-An isotope is an atom that has gained an extra neutron.
6. True
-Oxygen is more electronegative than most of the halogen elements.
7. True
-Cellulose and starch are both polymers made from a glucose monomer.
8. True
-During DNA replication both strands that make up the double helix are used as a template that new strands copy.
9. True?
- I think the question is referring to a codon/nucleotide triplet, because each base cant specify a single amino acid and nucleotide triplets are made up of three nucleotide bases so id say true.
10. True
-Side chain groups vary in size, shape, charge, hydrophobicity, and reactivity, which makes them unique.
Answer:
The dialysis tubing is semi permeable in nature which means that it allows some molecules to pass through it while hinders the movement of other molecules.
<u>Process:</u>
A dialysis tube filled with water and sugar when placed in pure water will act as a setup that can depict the process of Osmosis. Sugar molecules will not be able to pass the membrane while pure water molecules will move from the area of higher concentration to the area of lower concentration (inside the dialysis tube). This is because the pure water is less concentrated while the water in dialysis tube contains more concentrated solution. This will also increase the liquid level in the dialysis tube.
<u>For example:</u> If we have a dialysis bag that is not permeable to sugar but is permeable to water and it is was placed in a
beaker full of pure water.
Suppose the bag’s initial weight was 15g but after 15 minutes the bag's weight can change upto 17 grams, why it happened is due to process of osmosis of movement of pure water into the dialysis bag.
Hope it helps!
Answer:
The correct order is:
* DNA helicase unwinds the DNA
RNA primase synthesizes
a primer which attaches
to the initiation point.
DNA polymerase extends the
primer by adding nucleotides
that are complementary to the
template strand
DNA polymerase removes
RNA primers and replaces
them with DNA nucleotides.
DNA ligase seals the gaps
between new DNA and
Okazaki fragments.
Explanation:
Replication is the mechanism that allows DNA to duplicate. The process is carried out by a semi-conservative model, it is bidirectional and the direction is in the direction 5´-> 3´. It consists of 3 phases: initiation, elongation and termination.
Light will increase the rate of photosynthesis, should be reflected in the rate of disk rising
- no disks should rise in dark since photosynthesis requires light
