The answer is A btw you don’t have to use that chart the best way to do or the easy way to do it by doing it on the amino acid wheel it’s much better and faster.
Let me know if you have any questions:)
Answer:
Another name is <u><em>Scapula</em></u>
The bones of the shoulder consist of the humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collar bone). The clavicle is the only bony attachment between the trunk and the upper limb. The familiar flat triangular bone at the back of the shoulder. Known familiarly as the wingbone or, medically, as the scapula. The word "scapula" (with the accent on the first syllable) is Latin.
Explanation:
Hope this helps :)
If I told too much the answer to your question is <u><em>Scapula </em></u>
Answer:
13
Explanation:
The atomic number for Aluminum (Al) is 13. If you have access to the periodic table, this would've taken a few seconds.
Answer:
An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population. Natural selection results in organisms that are more likely to survive and reproduce.
Answer:
When a muscle cell contracts, the myosin heads each produce a single power stroke.
Explanation:
In rest, attraction strengths between myosin and actin filaments are inhibited by the tropomyosin. When the muscle fiber membrane depolarizes, the action potential caused by this depolarization enters the t-tubules depolarizing the inner portion of the muscle fiber. This activates calcium channels in the T tubules membrane and releases calcium into the sarcolemma. At this point, <em>tropomyosin is obstructing binding sites for myosin on the thin filament</em>. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites. Myosin heads bind to the uncovered actin-binding sites forming cross-bridges, and while doing it ATP is transformed into ADP and inorganic phosphate which is liberated. Myofilaments slide impulsed by chemical energy collected in myosin heads, <u>producing a power stroke</u>. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.
