Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.
Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.
Weak contraction
- Potassium accumulates in the sarcoplasm.
- Contracted lower sarcoplasm pH.
- Begin contraction with muscle already 50%.
- The circular arrangement of muscle fascicles.
Stronger contraction
- Increase in muscle belly circumference.
- A lesser proportion of motor neurons to muscle fibers.
- Increased recruitment.
- Increased stimulus frequency.
It is d. If it was adaptation, the organism would have stayed in order to adapt. The species moved in order to not go extinct. It can not be speciation, because a new species was not made. It is stimulus. It experienced too much heat, so it left.
The message would change because each base has a specific pair that it bonds with. So the original strand's matching sequence would be (ACT GCT) if they were to change the last letter of the first set of 3 numbers, it would be (ACA GCT), and you can see there is a difference in the first sequence of bases. Hope this helps (:
It’s Wolf biologists are a specific type of wildlife biologist - a scientist employed to observe and study animal behaviors. In this case, their research and study are limited to wolves. They spend time in the field observing the wildlife and their interactions with each other, prey animals and the ecology.
