Juliette [100K]

Answer:

Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called <u>primary </u>tumors or ones that can move called <u>metastatic </u>tumors.

Explanation:

The term primary tumor refers to the original tumor, a place where the tumor first appeared.

Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.

For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.

Which protein inhibits interaction between actin and myosin to prevent skeletal muscle contraction; and which ions remove the in
zloy xaker [14]

Answer:

Tropomysin, calcium

Explanation:

Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.

Muscle will only contract when they get a rush of calcium ions.

The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
