Do cats have internal fertilization or external fertilization?
Tigers have Internal Fertilization. (occurs inside the body). Tigers copulate frequently and noisily and repeatedly for 5 or 6 days. Each usually take about 20 to 30 seconds. Then the gestation period is 16 weeks.
What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
What is the difference between external fertilization and internal fertilization?
External takes place outside the female, as with fish eggs on which the male fish places his sperm. Internal fertilization, in plants and animals, takes place within the organism's structures, where the gametes are joined. In humans, in vitro fertilization (i.e. test tube babies) is a form of external fertilization in that it bypasses the normal occurrence in the fallopian tubes, and then directly implants the fertilized egg(s) in the uterus.
Do turtles use external fertilisation?
Amphibians undergo external fertilization and need to do this in the water. Both the male and female amphibians release their gametes close to each other after which fertilization will take place.
How is the number of eggs an animal produces related to its form of fertilization and development?
Animals that reproduce through external fertilization typically produce a large number of eggs because there is lower chance of each egg surviving to adulthood. In contrast, animals that reproduce through internal fertilization often produce fewer eggs but invest more energy and resources in caring for them due to higher survival rates. This relationship is influenced by the species' reproductive strategy and environmental conditions.
Do whales fertilize internally or externally?

What are the advantages of internal fertilization?

How do the relative size of the external and internal jugular veins differ in humans and the cat?
In humans there is one external and one internal jugular vein. The internal jugular vein is much larger (about twice the diameter) of the external jugular. In the cat there are a pair of each vein but the external jugular vein is about twce as large as the internal. (Opposite of humans.)
How does internal sovereignty differ from external sovereignty?
internal sovereignty = state is the highest authority within that territory external sovereignty = the recognition by all states that each state possesses internal sovereignty in equal measure
Is Arachnid Fertilization external or internal?
they fertilize eggs internally; just before they lay the eggs, the female releases the 'sperm packet' fertilising each egg individually. The sperm is gained through the peripalps which is located near the mouth of the spider.
