Answer:
Explanation:
Whales and humans have alot of things in common, they are the largest groups of mammals in the world.
Whales which belong to cetaceans(group of marine mammals) can be considered human, they possess self awareness, feelings and high-level cognitive power than man.
They have large brain size which suggests that they have a complex and elaborate evolutionary history.
Humpback cerebral cortex, the part of the brain where though processes takes place are similar to that of man. Humpback whales exhibit complex social patterns that include good communication skills, collaboration and good tool usage.
Whales and human are quite social in nature.
Answer:
A whale's fin is a major homologous structure. When you examine a whale's skeleton, you'll find that all of its bones are comparable to those of other mammals. As mammals, whales share a common ancestor with other mammals, including humans. Humans and humpback whales belong to the same kingdom (Animalia), phylum (Vertebrates), and class (Mammals) which means they are related but not too close. Humpback whale embryos still have limbs, but when they become adults, they become dormant, meaning the ancestor of today's humpback whale walked on land with humans in the past and therefore may have some evolutionary relationship with us.
The other body systems that play a direct role in removing waste products from the body are the digestive and respiratory systems.
Body systems may be defined as the collection of numerous numbers and kinds of organs that are arranged together in order to perform complex functions for the body which facilitates the rate of survival of organisms.
Some examples of body systems are the skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems.
The excretory system is known as the fundamental system in order to eliminate toxic waste materials from the body. But along with it, the respiratory system involves the exchange of gases through which carbon dioxide is eliminated from the body.
Apart from this, the digestive system facilitates the removal of solid wastes in the form of feces.
Therefore, the other body systems that play a direct role in removing waste products from the body are the digestive and respiratory systems.
