Answer:
sarcoplasmic reticulum deteriorates and ATP production is stopped
Explanation:
Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.
Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.
Answer:
Explanation:
1.) All organisms differ in traits such as size and behavior.
2.) No two individuals are exactly alike.
3.) There was a gradual change in each species.
4.) Fossils were different from the living animals. However, these fossils had many similarities to modern forms of life.
5.) Species on the Galapagos Islands resembled species on the mainland but they were different in certain characteristics.
6.) Some organisms became isolated on many islands.
Everlasting cells are cells that are incapable of regeneration. these cells are taken into consideration to be terminally differentiated and non-proliferative in postnatal lifestyles. This includes neurons, heart cells, skeletal muscle cells, and pink blood cells.
Pink blood cells (RBCs) fall right into a truly less complicated category. Mature RBCs do not divide. In truth, because mature RBCs do not even have a nucleus, those cells in reality can not do an awful lot of anything other than act as vessels for the hemoglobin with which they are jam-packed. New RBCs are made in the marrow within the mature human.
Because the mitochondria are the mobile website for oxidative metabolism, where glucose is damaged all the way down to carbon dioxide and water to release energy, and because purple blood cells lack these organelles they cannot break down glucose absolutely aerobically.

Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!
Hope this helps!
