The rapid speciation of mammals as a result of the availability of new habitat due to the extinction of the dinosaurs 65 million years ago is an example of adaptive radiation.
Many plants depend on animals primarily insects for pollination and sexual reproduction. If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct.
Both plants and animals undergo cellular respiration producing Carbon Dioxide. Animals produce only Carbon Dioxide while plants produce both Carbon Dioxide and Oxygen. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.
Plants that survived the extinction of animals would be much simpler than presently complex plants.
Perhaps some plants would become predators of other plants to absorb the nitrogen content of other plants because of the lack of animals to engage in the recycling of nitrogen content.
<h2>The brain ventricle located in the diencephalon is the <u>third</u> ventricle.</h2>
Explanation:
Brain Ventricles:
- Ventricles are the communicating network
- It is filled with CSF (cerebrospinal fluid )
- This is responsible to transport the above fluid around the cranial cavity.
Ventricle system consists of "2 lateral ventricles", "the third ventricle", "the cerebral aqueduct", and the "fourth ventricle".
diencephalon:
- This is the division of fore brain.
- This relays sensory information
- Controls autonomic functions
- It is also termed as "between brain" or "interbrain"
Yes because type O blood is the universal donor.
