Answer:
The correct answer is "Charles Lyell".
Explanation:
Charles Lyell was a notorious Scottish geologist that associated events of Earth's history with natural events taking place at the same time. In 1830, Charles Lyell published the book "Principles of Geology", associating the formation of the Earth's crust with different small and vast natural events. Charles Darwin's was largely influenced by Lyell's ideas and he took his book during the famous travel trough the Galapagos islands.
The correct answer is Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.
In the case of Jose artificially active immunity has been induced due to vaccination. A vaccine instigates a primary response against the antigen without resulting in any signs of the disease. On the other hand, Karl will acquire active immunity naturally in future, as when an individual get exposed to a live pathogen, he or she develops the disease, and turns immune as an outcome of the primary immune response.
Answer:
K+
Explanation:
Leak channels are the gated channels that randomly open and close. The plasma membranes have many more potassium ion (K+) leak channels than the leak channels for other ions such as sodium ion. Also, the potassium ion leak channels are leakier than the sodium leak channels and allow exit of more and more K+ from the neurons. This makes the inside the neuron negative at rest and outside becomes more positive. In this way, the leakage of K+ across the K+ leak channels is mainly responsible for maintaining the resting potential.
