Most animals with backbones, vertebrates, have a similar body plan: skull, ribs, two pairs of limbs, tail. What does this sugges
daser333 [38]

The correct answer is E. Vertebrates are all related to a common ancestor

Explanation:

According to biology and evolution, organisms from different species but that share similarities in morphology (body structures) as well as in genetics often have a phylogenetic relationship which means they descend from the same organism or share a common ancestor. This applies to multiple taxonomical levels including classes such as mammals or birds as it has been proved each of this derived from a common ancestor. Therefore, the similarity in the body structure (morphology) in all mammals suggest vertebrates are related to a common ancestor and as they evolved from this, they share similarities not only in terms of morphology but also in genetics.

Whole brain death occurs when the ______ ceases to function.
xz_007 [3.2K]

Answer:

Whole brain death occurs when the BRAINSTEM ceases to function.

Explanation:

In the US, whole brain death = legal death. Most people consider that a person is brain dead when the cerebrum, or the higher brain, is dead because the person is not able to think or have control over his/her body, but legally you are brain dead only when the brainstem ceases to function. The brainstem is responsible for keeping you alive and performing the most basic bodily functions like breathing and keeping your heart beating. But once it fails, you are legally dead. Even if your body could still survive using a ventilator and other devices, your brain has ceased to work and you wouldn't be able to survive if you were unplugged.
