Answer:
Excitement
Explanation:
Sympathetic nervous system is a type of autonomic nervous system that acts as an emergency system of the body.
Sympathetic nervous system prepares the body during fight and flight response. The energy is put out in this system and protects the body from the injury. During excitement the heart speeds up, blood pressure increases and more energy is available to the body. Hence, excitement is the characteristic of sympathetic division of nervous system.
Thus, the correct answer is option (b).
Answer:
Reactants of the cellular respiration process are:
1. C6H12O6
The phase reactant is used: Glycolysis
Location: cell cytoplasm
In cellular respiration, the glucose is used up in the phase known as glycolysis which is performed in the cell cytoplasm that breaks the glucose into 2 molecules of pyruvate.
2. 6O2
The phase reactant is used: oxidative phosphorylation
Location: mitochondrial matrix
Oxidative phosphorylation is the phase of cellular respiration that forms the ATP by the transfer of the electron to the oxygen which reduced the oxygen to water.
Products of cellular respiration are -
1. 6CO2
The phase reactant is used: Krebs cycle
Location: mitochondrial matrix
2. 6H2O
The phase reactant is used: oxidative phosphorylation
Location: mitochondrial matrix inner membrane
3. 38ATP
The phase reactant is used: oxidative phosphorylation, Glycolysis, Krebs cycle
Location: mitochondrial matrix, cell cytoplasm and inner membrane mitochondrial matrix
Answer:
This is because crossing over occurs between two homologous chromosomes. It involves an exchange of segments of their arms of the two chromosomes during Metaphase I of meiosis. Genes on the different chromosomes are, therefore, more likely to be crossed over than genes on the same chromosome. In addition, because sections of the arms are exchanged, genes that are close to each other on the same chromosome are more likely to be exchanged together (these are called linked genes) than genes that are far apart on the same chromosome.
