Explain scientifically whether humans and humpback whales share a close evolutionary relationship.

Answers

Answer 1

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 2

Answer:

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.

At what point do particles have no kinetic energy

Answers

A temperature of absolute zero is the point at which the gas particles stop moving. This corresponds to a temperature of . Particles have no kinetic energy at all so no energy can be removed and the temperature cannot get any lower. With no kinetic energy and now stationary, the particles will exert no pressure either.

Many bacteria are able to pass small pieces of the hereditary information on their DNA from one bacterial cell to another. This can sometimes result in an increase in the number of drug-resistant bacteria. What name is given to the process by which one bacteria transfers DNA to another? A) sporolysis B) conjugation C) gametic transfer D) haploid translocation

Answers

Answer:

The process in which one bacteria transfers DNA to another is called conjugation.

Explanation:

Conjugation is the process of transferring genetic material from one bacteria to another through direct cell contact. In the process of conjugation one bacteria acts as donor and transfer the DNA to a recipient. There is a specific DNA sequence present in Donor's DNA called fertility factor (F factor). F factor helps in the formation of pillus which is the site of genetic material transfer.

Which correctly compares how coal and natural gas are formed? A.
