Yes. A woman normally produces one egg a month. A man produces enough sperm to repopulate the earth with each mating if all were used. All sprerm attempt but only one gets through to the egg then the 'door is shut for all the rest.

Yes. All mammals have internal fertilization.
No, in external fertilization, not all eggs are fertilized. The eggs are released into the environment and must be externally fertilized by sperm for fertilization to occur. Many eggs may not encounter sperm and therefore will remain unfertilized.
NO- the vast majority of the commercial eggs are infertile- the hen never sees a rooster. Fertilization of the egg happend BEFORE the shell membranes and shell are added. Fertilization is not needed to form a shell.
A follicular study is one that is conducted for in-vitro fertilization. This study basically nails down the assessment of the eggs and the timing of the eggs.
Depending on the species, egg-laying occurs anywhere from three to eight weeks after mating. The American crocodile lays eggs approximately three weeks after fertilization; Nile crocodiles lay eggs about eight weeks after fertilization; Saltwater crocodiles lay eggs four to six weeks after fertilization.
Usually, it doesn't. The only thing that would be different is that internal fertilization, there is less eggs because they are protected in the mother's body. The external fertilization, there is more eggs because of the lesser chance of survival
It is external because we all know that fish lay eggs and they lay eggs in their habitat so its meant to say that the fish, develop their embryo inside the egg and also where it is hatch.
Fertilization
all animals have eggs, but it depends their fertilization development type (which is either internal or external). Humans are mammals, and all mammals give live birth unless it is a monotreme, which lays eggs.
An ostrich lays eggs after the mating ritual. Therefore, the fertilization process is internal.
Seahorses reproduce sexually, with the male seahorses fertilizing the females' eggs. After fertilization occurs. the females transfer the eggs to the males, who keep the eggs stored in a pouch until hatching.
