The Ferrel cell is the middle cell, one of the three cells in each hemisphere in which air circulates through the entire depth of the troposphere. This cell occurs between 60 and 70 degrees north and south and <span> the surface wind flows from a southerly direction in the northern hemisphere. From the given options, in a Ferrel cell a Westerlies can occur. </span>
An elements number of protons is the same as its atomic number. In this case there would be 43 protons
Answer: Adaptations to a common environment and examples of convergent evolution.
Explanation:
Ichthyosaurs were the giant marine reptiles but it possess tails and dorsal fins though this is not a common character of reptiles. But the presence tails and dorsal fins states that it was an adaptation which was required at that time.
This giant reptile was an mixture of modern fish and dophins. It also had dorsal fin for swimming in water and has vertical tail which was used for the propulsive stroke. They were air breathing but had some part of their life in water as well like other reptiles.
Convergent evolution can be defined as the evolution of similar features in the species found at different period.
Some of the fishes like dolphins and other fishes shows convergent evolution to ichthyosaurs.
The EEG scan of the brains of children with autism SHOW FEWER BRAIN REGIONS WITH SYNCHRONIZED BRAIN WAVES compare to the brain of the control group. This means that there is decreased connectivity throughout the brain of those with autism.
