What is the name of the groove that forms in the middle of a dividing plant cell
mrs_skeptik [129]

Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate  forms across the cell in the location of the metaphase plate.

There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.

A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.

The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.

"describe how prolonged immobilization results in muscle injury"

<span>Rhabdomyolysis constitutes a common cause of acute renal failure and presents paramount interest. A large variety of causes with different pathogenetic mechanisms can involve skeletal muscles resulting in rhabdomyolysis with or without acute renal failure. Crush syndrome, one of the most common causes of rhabdomyolysis presents increased clinical interest, particularly in areas often involved by earthquakes, such as Greece and Turkey. Drug abusers are another sensitive group of young patients prone to rhabdomyolysis, which attracts the clinical interest of a variety of medical specialties. We herein review the evidence extracted from updated literature concerning the data related to pathogenetic mechanisms and pathophysiology as well as the management of this interesting syndrome. Keywords: Rhabdomyolysis, acute renal failure, myoglobin, crush syndrome The first case of the crush syndrome, which constitutes one of the main causes of rhabdomyolysis, was reported in Sicily in 1908, after an earthquake1,2. In 1930, in the Baltic area, an epidemic of myoglobinuria was observed due to consumption of contaminated fish. Interest in rhabdomyolysis and crash syndrome was stimulated during the World War II particularly after the bombing in London, where the victims developed acute renal failure and myoglobinuria1. Rhabdomyolysis is a rupture (lysis) of skeletal muscles due to drugs, toxins, inherited disorders, infections, trauma and compression3. Lysis of muscle cells releases toxic intracellular components in the systemic circulation which leads to electrolyte disturbances, hypovolemia, metabolic acidocis, coagulation defects and acute renal failure due to myoglobin4. The skeletal muscle consists of cylindrical myofibrils, which contain variant structural and contraction proteins. Actin and myosin, arranged in thin and thick filaments respectively, form the repeated functional units of contraction, the sarcomeres5. The sarcoplasmic reticulum constitutes an important cellular calcium storage. It is structurally connected to the t-tubules, that are formed by invaginations of the muscle cell plasma membrane, the sarcelemma, around every fibril (Figure 1). After the sarcelemma depolarization, the stimulation arrives, through the t-tubules junctions, at the sarcoplasmic reticulum, inducing the calcium ions release and triggering muscle contraction6.</span>

*<br> Which is a type of scavenger?<br> Hyena<br> Lion<br> Bear<br> Deer
DerKrebs [107]
I think that I might be HYENA.

Since they don’t really kill they are mostly “scavengers”

I am not 100% sure though. I hoped I helped at least a little.
