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:
Central and Peripheral
Explanation:
The nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord.
On the other hand the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.
The below diagram provides a schematic view of the role of each sub-division of the Nervous System.
Answer:
The correct answer would be -
Membrane A - Hypotonic solution - the movement of water towards inside the cell
Membrane B - Isotonic soltion - there will be no movement of water
Membrane C - Hyertonic solution - the movement of water towards outside of the cell
Explanation:
This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.
In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.
Thus, the behavior of the membranes are-
Membrane A - Hypotonic solution - the movement of water towards inside the cell
Membrane B - Isotonic soltion - there will be no movement of water
Membrane C - Hyertonic solution - the movement of water towards outside of the cell
The right answer is: Leptin
.
Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.
A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.
Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
