Does a puffin have a backbone?

Yes, puffins are birds and like all birds, they have a backbone. Their backbone, or vertebral column, supports their body and provides structure for their movements.


Does a yak have a backbone?

Yes, a yak has a backbone. As a mammal, it is part of the vertebrate group, which means it possesses a spine made up of vertebrae. This backbone supports the animal's body structure and protects its spinal cord.


What fish group gave rise to the terrestrial vertebrates?

The group of fish that gave rise to terrestrial vertebrates is known as lobe-finned fish. These fish had fleshy fins with bony supports that eventually evolved into limbs capable of supporting the animals on land. The transition from water to land occurred during the Devonian period, around 360 million years ago.


What is a exoskeleten?

An exoskeleton is a rigid external covering that supports and protects the body of certain animals, such as insects and crustaceans. It provides structure, support, and protection for the organism's soft tissues and helps with movement.


How does DNA evidence support whales evolutionary pathway?

DNA evidence supports whales' evolutionary pathway by revealing genetic similarities between whales and terrestrial mammals, particularly artiodactyls like hippos. Molecular studies show that whales share a common ancestor with these land-dwelling mammals, indicating a transition from land to water. The analysis of specific genes and DNA sequences has helped trace the evolutionary changes that enabled adaptations for aquatic life, such as modifications in limb structure and respiratory systems. Overall, genetic data provides a clear molecular framework that aligns with fossil evidence of whale evolution.

Why is mars called at terrestrial planet if there no life for it to be called a terrestrial planet?

Mars is called a terrestrial planet because it shares similar characteristics with Earth, such as a solid surface, rocks, and mountains. The term "terrestrial" refers to rocky planets that are similar to Earth, not necessarily that they support life. Mars is considered terrestrial because of its composition and structure, not because it currently supports life.


When oxygen gas supports combustion is it called physical or chemical change?

When oxygen gas supports combustion, it is considered a chemical change. This is because a new substance is formed through the reaction between oxygen and the fuel, resulting in the release of heat and light.

Does a otter have a back bone?

Yes, otters have a backbone. They are mammals and, like all mammals, possess a vertebral column (spine) that supports their body structure. This backbone is part of their skeletal system, allowing them to move and function effectively in their aquatic and terrestrial environments.
