Photosynthesis and cellular respiration are similar because they both involve organic and inorganic compounds.
Answer:
The distance between A and B is less than the distance between B and C.
Explanation:
Crossing over is the exchange of genetic segments that occurs between the chromatids of homologous chromosomes during prophase I of meiosis I. The process of crossing over requires the genes to be present on different chromosomes.
Linked genes are the ones that are present on the same chromosome. Linked genes that are present far apart on the same chromosome may undergo crossing over but the genes present close to each other on the same chromosome are least likely to undergo crossing over. Therefore, the frequency of crossing over increases with increased distance between the genes.
According to the given information, crossing over frequency between genes A and B is 0.1 while that for the genes B and C is 0.3. Since the genes B and C have more crossing over frequency, they are located far apart from each other than the genes A and B. Distance between A and B genes is less than the distance between B and C genes.
Answer:
a. Mitochondrial DNA is inherited through the maternal lineage.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
Explanation:
DNA is the genetic material. Nuclear DNA profiling is used to identify a person since each individual has unique DNA. Mitochondrial DNA exhibits maternal inheritance. All the offspring of a female share the same mitochondrial DNA. Therefore, all the individuals that are related by maternal lines, share the same mitochondrial DNA. The profiling of their mitochondrial DNA would not allow the identification of a person when individuals share maternal lines.
The mean rate of photosynthesis when the carbon dioxide concentration was 0.2% is 8 .
<h3>What is photosynthesis?</h3>
The process of photosynthesis is defined as the green plants prepare there own food in the presence of sunlight and during this process heat energy is converted into chemical energy is known as photosynthesis. The process is takes place only in green plants as they contain chlorophyll.
The plant use water, carbon dioxide, nitrogen in the form of nitrates, sunlight and sugar as the source of energy to prepare its own food. Plants prepare there own food so they are known as autotrophs.
Therefore, The mean rate of photosynthesis when the carbon dioxide concentration was 0.2% is 8 .
