Answer:
Explanation:
Muscle contraction is stimulated by the movement of an action potential moving along a nerve fiber to the muscles. This event follow some series of process before being stimulated.
1. The impulse arrives at the synapse and travels through the transverse tubules.
2. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
4. Tropomyosin molecules bind to exposed active sites, linking actin and myosin.
5. Thin filaments are pulled over the thick filaments.
6. The muscle fiber shortens and contracts.
Forming an hypothesis, gathering materials, performing your experiment, and determining the conclusion. Also determining independent and dependent variables could be one depending on the teacher. Sorry if I’m wrong!
No abiotic things are non-living, and cells are living.
Answer:
Increase
Explanation:
The predator is a type of animal or bird species which kill other animals to obtain its food. The prey is the animal which is killed by the predator. According to the given situation, if the predator species A is eliminated, the population of the predator B will likely increase because there will be no competition between the two species for the same prey. And the chances of predator B obtaining the prey will increase. Hence, the population will increase.
I can’t see the image but I would guess animals such as deer or horse or elephants or any large animal have the ability to run over the rocks and turn them to smaller sediments
