Viruses can multiply very quickly, and so they can go through natural selection at a much quicker rate, allowing certain vaccine resistant mutations to take over a population.
Answer:
Sartorius and Stapedius muscle
Explanation:
Sartorius is the longest and stapedius is the thinnest
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
This is likely a mutant mouse (as synaptic clefts are typically 10 to 20 nm wide). Given that neurotransmitters act over short distances, this mouse may demonstrate delayed responses to stimuli, or no responses at all.
That’s the answer
Answer: While active transport requires energy and work, passive transport does not.
