Answer: sediment deposited by the sediment flow of mass wasting are the slowest type of mass wasting
Mass wasting is the movement of large mass of rocks, boulders, slit, soil, sediments and ice down a slope. It occurs during retreating glaciers, landslides and mudflows. Moraine is a glacier deposit that develops during a retreating glacier. It develops when a glacier melts and it leaves sediments of ice, rocks and others over an area. As, the glacier ice may melt slowly, it is a product of slowest type of mass wasting.
During sperm penetration, human eggs are still surrounded by follicular cells.
Therefore, the correct answer is Option D.
<h3>What changes does egg undergo for fertilization?</h3>
- An egg goes through a few changes at the hour of sperm penetration during fertilization.
- These progressions happen at the cell surface, in development, physiology and gene expression.
- For fertilization, a sperm should combine with the cell membrane and afterward infiltrate the egg cells.
- Infiltration through the egg cell or extracellular matrix (ECM) is a troublesome task.
- The acrosome of the egg goes through acrosomal reaction to get through the hard shell of cell.
- To go through the follicle cells encompassing the egg or oocyte, the sperm discharges hyaluronidase enzyme.
- This chemical isn't delivered until the sperm comes into contact with the egg cell's zona pellucida.
