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.

Answer:
diseño aerodinámico, aletas
Gresham Sykes and David Matza termed this technique B. denial of injury.
A is incorrect because they are not appealing to the higher loyalties, they are simply denying something. They are also not denying their responsibility, because they obviously stole the car. They are also not condemning other people because they know the responsibility is theirs. Thus, B is the correct answer - they say they didn't hurt anyone - this is what they are denying.
Answer:
ABG - Arterial blood gas findings
Explanation:
The ABG test measures the pH and the oxugen and CO2 levels in the blood that goes through the arteries.
Brown eyes + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene. If not, the chance is 0% Brown eyes + brown eyes = 25%, but only if both parents carry the blue-eyed gene.
a 25% If both of you have brown eyes, then there is generally a 25% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1% chance of the baby having blue eyes.
