Answer:
The answers to both parts (1 and 2) are given below.
Explanation:
1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.
2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.
Answer:
Herbivorous animals are unable to feed and end up migrating to other regions in search of food.
Explanation:
The tundra is a type of vegetation composed almost exclusively of mosses and lichens. This type of vegetation is found in regions with a polar climate. It is important to note that the tundra has a very fast vegetative cycle. That's because it freezes quickly and can be covered with ice all winter. This ends up modifying the lives of some animals that feed on this vegetation. These animals end up with unavailability of food and need to migrate to others in search of food.
Answer:
1. replication
2. gene
3. strand polarity
4. translation
5. complementary base pairing
6. chromosome
7. antiparallel
8. transcription
9. allele
Explanation:
1. Replication is the process by which DNA is duplicated or the process of making another copy of DNA.
2. Gene is the physical unit of heredity i.e a segment of DNA transferred from parents to offsprings. A gene also encodes a useful products such as protein.
3. A DNA strand is a polar molecule, which is attributed to the phosphate group at the 5'-end of DNA and the hydroxyl group at the 3'-end of DNA.
4. Translation is the process whereby the information in a mRNA molecule is used to synthesize a protein.
5. Complementary base pairing is a phenomenon whereby Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C).
6. A chromosome contains of single long molecule of DNA coiled together around histone proteins. The chromosome is associated with different types of proteins.
7. In the double-stranded DNA molecule, one strand runs from 5' to 3' and the other runs from 3' to 5'. This is called ANTIPARALLEL nature of DNA.
8. Transcription is the process by which a DNA molecule is used to synthesize a mRNA single strand.
9. Allele is the alternative or contrasting form of a gene. Each allele is contributed by each parent
Answer:
Changes in temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators can affect enzyme activity.
For example increasing substrate concentration increases the rate of reaction.
Explanation:
This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed.
