Your answer is A.) Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells
During mitosis, a cell duplicates and divides to create two cells identical to the parent cell. During meiosis, the same thing occurs, except the daughter cells divide again, without duplicating. This creates 4 haploid cells.
Hope this helps!
Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.
Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.
Answer:Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
Answer:
The food we eat - our diet - is made up of different biological molecules which gives us energy and contain chemicals we need to grow and repair ourselves and help our cells function in our body.
Carbohydrates and fats are made up of carbon, hydrogen and oxygen.
Proteins contain carbon, hydrogen, oxygen and nitrogen.
