The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:
A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.
B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
C. Crossing over between homologous chromosomes during prophase I of meiosis.
D. Replication of chromosomes prior to meiosis.
E. Independent alignment of different homologous pairs on the metaphase I spindle.
Answer:
The correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
Explanation:
The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.
This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.
Thus, the correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
Answer: A B C
Explanation:
The synthesis of ATPS takes place in the mitochondrial and chloro plasts of cells.It is an exergonic reaction that involves the use of energy released from influx of protons to for the catalysis of in organic phosphate and ADP by enzyme ATP Synthase in the stroma and matrix of chloroplasts and mitochondrial respectively.
The 3 bonds that connected phosphate ions to ADP to form ATP must be broken down(hydrolysis) with water to release the energy for biochemical activities of the cells.
The first bond hydrolysis releases first phosphate and ATP changed to ATP,
The second bond releases breakage changed the ADP to AMP with the release of more energy.
When molecules uses energy for transportation across the cell, then it is known as "Active Transport"
So, option B is your answer.
Hope this helps!
