AnsweR:
Rough endoplasmic reticulum.
Explanation:
The endoplasmic reticulum is a member of the endomembrane system and is present as a continuation of the nuclear membrane. They are divided into the rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum has ribosomes on its surface and is responsible for the synthesis of secretory proteins. Smooth endoplasmic reticulum synthesize lipids.
Therefore cells that intensely biosynthesize secretory proteins like neurons, white blood cells have a greater amount of rough endoplasmic reticulum than another cell of the body.
The function is Hepatocytes
I believe the answer is B. They were no longer able to acquire the necessary characteristics for survival in a changing environment. I think it is B. because trilobites mostly went extinct because of the event that wiped out 95% of Earth's species. So they didn't have the characteristics to survive. Hope I helped!
<span>A person is able to squeeze a clothespin more times if they exercise beforehand because many body systems have been activated during the prior exercise. The respiratory system is activated providing increased oxygen to brain and other muscles. The circulatory system is activated to move blood from lungs and brain to the proper muscles. The brain has been activated to a mechanical task such as muscle movement.</span>
Answer:
a. human body systems interact with each other to perform life functions
Explanation:
The digestive system like all other organ systems relies on other organ systems working efficiently for it to work. For example the food digested by the digestive system is transported around the body by the circulatory system. Moreover enzymes and hormones needed by the digestive system are transported to target cells through blood
