Answer:
True
Explanation:
Each replicated chromosome pairs with its corresponding homologous chromosome forming a tetrad. During tetrad formation, alleles can be exchanged between chromatids, a process called crossing-over.
Answer:
The optimum pH of ATP synthase is 6.4 therefore maximum activity will occur at pH7 by the vesicle, however because the concentration of the three , is relatively the same , and exhibited equal effects on the pH, catalysis by the vesicle will not take place BECAUSE NO HYDROGEN ION IS AVAILABLE to supply the energy
Generally the synthase activity decreases with drops in pH. The lower pH of 6.5 from the set point value , will affect catalysis.
The low pH lead to increase in concentration of base in the buffer solution. Therefore more H + are produced .for the synthesis of ATP. The vesicle catalyzed ATP production. But the increase in hydrogen ion concentration with time affect the 3 dimensional structure of the ATPase synthase enzyme in the vesicle and increases the inhibitory effect of ADP therefore the vesicle stops the catalysis.
B) The positive charge of the protons in the nucleus equals the negative charge in the electron cloud.
