Answer:
Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.
Answer:
We can see that Lucy has ADA-SCID due to the constant infections that she has, generated by microorganisms that are easily fought by the immune system.
Explanation:
ADA-SCID is a hereditary cataresis syndrome that leaves a person's immune system highly weak and sensitive, failing to combat simple microorganisms that pose no danger to humans with the normal immune system. People with these syndromes basically have no defense in their bodies and often have infections caused by organisms that are easily fought by a healthy immune system. In addition, these infections can progress to more severe clinical cases.
The correct answer would be D. beaks of finches
I chose this answer because in the Galapagos islands, the species of finches were forced to separate into several different environments, where there were different foods and plants. They lived in these environments for many years and eventually the beaks of these birds adapted to the environment around them. So the finches in one environment may have gotten longer beaks to eat fruits and get honey better, while one may have gotten a smaller but longer beak to gather and break nuts easier.
Hope this helps!
