What is the difference between internal and external fertilisation in animals?

Internal fertilization is like animals having sex....the egg is fertilized on the inside. External is when the egg is fertilized on the outside (like when frogs lay eggs and they need to be fertilized before they can hatch).


What relationship exists between an organisms habitat and its method of fertilization?

The organism's habitat can influence its method of fertilization based on the physical conditions required for successful reproduction. For example, in aquatic environments, external fertilization is common among species that release gametes into the water for fertilization to occur. On the other hand, in terrestrial environments, internal fertilization is more prevalent to ensure protection of gametes from drying out.


What is the relation between internal and external reflux ratio in distillation column?

The internal reflux ratio is the ratio of the liquid returned as reflux to the distillate product inside the column, while the external reflux ratio is the ratio of the liquid refluxed back to the column to the distillate product taken out of the column. These ratios are related as the sum of the internal and external reflux ratios is equal to the total reflux ratio, which can affect the separation efficiency and energy consumption in a distillation column.


Why do you think there is a basic difference between the kinds of fertilization most common in aquatic and terrestrial animals?

the process of fertilization involves fusion of egg/ova and spermatozoa. the two cells are also called gametes. for their meeting aqueous medium is required. in land animals out side environment is dry therefore fertilization on land is not possible while as genital tract provides similar aqueous atmosphere where spermatozoon swim to reach the egg.


How can you distinguish between external and internal stimuli?

External stimuli come from outside the body, such as light or sound, and trigger a response through the sensory organs, like eyes or ears. Internal stimuli originate inside the body, such as hunger or pain, and are detected by internal sensory receptors like nerve endings or hormones.

What is the difference between internal fertilization and-external fertilation?

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.
