Answer:
A função do citoplasma é fornecer sustentação esquelética para a célula através da estrutura composta por filamentos e túbulos proteicos. Além disso, todo o conjunto de estruturas mergulhadas no citosol apresenta bastante dinamismo, fato que possibilita à célula realizar alguns movimentos.
No citoplasma, ainda há membranas que atuam como verdadeiras usinas intracelulares, que fornecem energia indispensável à manutenção da vida.
Outro fato que você deveria saber sobre o citoplasma é que ele preenche todo o interior das células eucariontes, sendo delimitado pela membrana plasmática. Já nas células procariontes, o citoplasma fica entre a membrana plasmática e o núcleo da célula.
Explanation:
1. Regulation of glucose blood levels is an example of negative feedback mechanism.
Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.
Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.
• Pancreatic cells-sensors
• Insulin-control system
• Body cells- effector cells
2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.
This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.
3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.
Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
The density of water is 1.0kg/L
I am pretty sure the answer is cytoplasm
