Production of the mature sperm cells have 4 step process beginning at puberty and throughout the male's lifetime. Spermiogenesis is the final process for production of sperm where the spermatids mature into motile spermatozoa. For humans, the spermatogenesis takes 74 days to 120 days and if the transport on the ductal system is included it would take 3 months.
The three major factors that can contribute significantly to a project success are (1) timely user involvement, (2) executive management support, and (3) a clear user requirements. There are other success criteria, but with these three elements in place, the chances of success are much greater
(Do whatever you want with this information lol, but honestly I hope this helps)
The client should remove all metal objects (such as piercings, rings, jewelry of any kind) the day of the scan.
Answer: C. Above the kingdom level
Explanation:
Hierarchical classification can be defined as the system of grouping living beings according to the level or orders. Domain secures the highest taxonomic rank in the biological hierarchical classification system. This lies above the Kingdom level. The life forms are classified into three domains, which are Archea, Eukarya and Bacteria.
Explanation:
The spinach leaves would have a higher photosynthetic rate due to the additional carbon dioxide provided from the sodium bicarbonate solution. Sodium bicarbonate NaCO3, breaks down to release dissolved carbon dioxide gas. This is taken up by the leaf for photosynthesis which begins in the stroma. Here,chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates in the process photosynthesis.
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate-limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
- No, the light-independent pathway cannot occur when the discs are placed in the dark environment-this is because during the light dependent process then the products of light dependent reactions ATP and NADPH, along with several enzymes are used in the Calvin cycle which produces energy storage molecules like sugars/ carbohydrates and other organic molecules. Respiration, occurs at the same time,producing CO2 as a byproduct. However, this doesn't affect photosynthesis; plants are living organisms that need more energy for metabolic processes like the Calvin Cycle .
- Photosynthesis occurs faster in the cops containing bicarbonate solution. This is due to the increased amount of carbon for use by the leaves in photosynthesis; the rates of reaction are higher in light environments because photosynthesis is a light-dependent process; the energy used and the light-dependent reactions produces ATP and NADPH which are then used to begin the Calvin cycle.
- This supports the hypothesis, that the syringe containing sodium bicarbonate at higher light intensities would produce more floating disks due to higher rates of photosynthesis, which releases water and Oxygen gas as end products, causing the disks to float to the top. Conclusion:<em>Thus at higher intensities of light, and in the pesence of sodium bicarbonate i.e. light environments the rate of photosynthesis is also higher and will occur faster; the Oxygen produced makes more leaf disks float.</em>
