polyspermy is a egg that was fertilized by multiple sperm. This is a major problem in most cells because due to this, there will be no sign of diploidy (2 set of chromosomes). The egg prevents this during the acrosomal process. The contact between the acrosome and the vitelline envelope triggers the egg to release Ca+ which changes the charge under the plasma membrane. This prevents other sperms from interacting. This is the first way that it is prevented. This way is often referred as the "Rapid Block"
For the "Slow Block", The cortical granules inside the egg (they're like these tiny vesicles just under the plasma membrane) fuse with the egg plasma membrane. this in turn triggers swelling of the space betweel the vitelline envelope and the plasma membrane. Afterwards, the vitelline envelope hardens.
What else can I help you with?
What hat happens if two sperms go into an egg?
If two sperm penetrate an egg, a condition known as polyspermy occurs. This usually results in an abnormal fertilization, leading to an imbalance in the genetic material, which typically causes the embryo to be nonviable and unable to develop properly. In many organisms, including humans, mechanisms exist to prevent polyspermy, such as changes in the egg's membrane after the first sperm enters. If polyspermy does occur, it often results in failed implantation or miscarriage.
What is the chemical that prevents clotting within the circulatory system?
The chemical that prevents clotting in the circulatory system is called heparin. Heparin is a naturally occurring anticoagulant that inhibits the formation of blood clots by potentiating the action of antithrombin III, which inactivates thrombin and other clotting factors.
What is the opposite reaction of a Catalyst?
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
What is the significance of cortical reaction?
The cortical reaction is a crucial process in fertilization, occurring shortly after a sperm penetrates the egg. It involves the release of enzymes from cortical granules in the egg's cytoplasm, leading to changes in the egg's membrane that prevent polyspermy, ensuring that only one sperm fertilizes the egg. This reaction also helps to initiate early developmental processes, contributing to the formation of the fertilization membrane. Overall, the cortical reaction is vital for successful reproduction and the proper development of the embryo.
Why do you shake tomato ketchup bottle before opening its cap?

A prevents actions from occurring?
inhibitor
What causes the slow block to polyspermy?
The slow block to polyspermy is caused by changes in the egg's membrane potential and increased intracellular calcium levels, which prevent additional sperm from fertilizing the egg. This physiological response allows only one sperm to successfully fertilize the egg and prevents the formation of abnormal embryos with multiple paternal contributions.
Result of polyspermy in humans is?
Nonfunctional zygote
What is the function of the fertilization envelope?
The fertilization envelope acts as a barrier that prevents polyspermy, which is when an egg is fertilized by more than one sperm. It also helps in the activation of the egg and plays a role in the early developmental processes of the embryo.
What would happen if 2 sperm penetrated an egg?
If two sperm penetrate an egg, a condition known as polyspermy occurs. This usually leads to an abnormal fertilization, resulting in an embryo with an incorrect number of chromosomes, which is typically not viable. In many organisms, mechanisms exist to prevent polyspermy, such as the fast block and slow block to polyspermy, to ensure normal development. If polyspermy does occur, it usually results in failed embryo development or miscarriage.
What is polyspermy in humans?
Polyspermy is when more than one sperm penetrate one egg during conception. Normally, there are blocks to polyspermy because humans are generally monospermic - only one sperm and one egg can create a viable zygote. Thus, there are biological blocks to polyspermy in humans.
Why is polyspermy bad for fertilization?
Polyspermy is bad for fertilization because it results in the fertilized egg having an abnormal number of chromosomes, which can lead to developmental abnormalities and prevent the embryo from developing properly.
Why polyspermy bad?
Polyspermy, the fertilization of an egg by multiple sperm, is detrimental because it leads to an abnormal number of chromosomes, resulting in genetic imbalances. This can cause developmental issues, embryo lethality, or infertility. In many organisms, mechanisms exist to block polyspermy, ensuring that only one sperm fertilizes the egg to maintain proper genetic integrity.
What prevents a pure monopoly from occurring?
Monopolies are usually bad for society so governments either nationalise them or regulate them.
What hat happens if two sperms go into an egg?
If two sperm penetrate an egg, a condition known as polyspermy occurs. This usually results in an abnormal fertilization, leading to an imbalance in the genetic material, which typically causes the embryo to be nonviable and unable to develop properly. In many organisms, including humans, mechanisms exist to prevent polyspermy, such as changes in the egg's membrane after the first sperm enters. If polyspermy does occur, it often results in failed implantation or miscarriage.
What Congressional aide prevents trouble from happening?
The correct answer is Sergeant at Arms " Another helper is the Sergeant at Arms, whose job is to prevent trouble from occurring on the Congressional floor."
What is the chemical that prevents clotting within the circulatory system?
The chemical that prevents clotting in the circulatory system is called heparin. Heparin is a naturally occurring anticoagulant that inhibits the formation of blood clots by potentiating the action of antithrombin III, which inactivates thrombin and other clotting factors.
