The correct answer is C. Mitosis produces 2 genetically identical diploid cells, while meiosis produces 4 genetically unique haploid cells.
Mitosis is where a parent cell duplicates its genetic information before dividing into 2, therefore, the daughter cells from mitosis are completely identical to their parent cell and the other daughter cell, and we call the cells which has complete genetic information as diploid. Mitosis is very useful in repairing, growth, asexual reproduction etc.
Meanwhile, meiosis involves 2 times of division. The parent cell first duplicates its genetic information, but then swapping them, and divide. 2 new cells are produced. Then these 2 cells are further divided but without duplicating the genetic material. Therefore, this results in 4 genetically different cells. We call them haploid, as they only have half of the chromosomes from their parent, which is the opposite of diploid. Meiosis is important in producing sex cells.
Answer:
The correct answer is option C- "oxidize, reduce".
Explanation:
Fermentation is a process analogous to cellular respiration and, just like the latter, it involves oxidization and reduction of molecules with the final purpose of producing energy. During the process of fermentation nicotinamide adenine dinucleotide + hydrogen (NADH) is oxidized to its original form of NAD with a plus charge; while other organic molecules such as piruvate are reduced.
Answer:
The correct answer is - electron transport system.
Explanation:
There are 3 main stages of cellular respiration (aerobic) that are Glycolysis, the Kreb's Cycle and the ETS or Electron Transport Chain. The formation of energy in ATPare as follows:
Glycolysis - glucose > 2 Pyretic Acid Molecules =>2 ATP and Hydrogen
The Krebs Cycle - Citric Acid (a derivative of Pyruvic Acid) > 2 ATP in 4 cycles and Hydrogen, carbon dioxide and water.
The Electron Transport Chain > electron carrying Hydrogens > releases the energy as 4 ATP and water
Thus, the correct answer is - The Electron Transport Chain is the stage that produces most of the ATP during cellular respiration.
I think b would fit more as the mitochondria, d would be the endoplasmic reticulum, and e would be lysosomes
Answer:
Spongy or cancellous tissue – the porous, honeycombed material found inside most bones, which allows the bone to be strong yet lightweight.
