Answer:
(D) all of the above
Explanation:
The rough endoplasmic reticulum is part of the endoplasmic reticulum, the other one is known as the smoother endoplasmic reticulum.
1. This rough endoplasmic reticulum is considered rough because it has ribosomes bound to it.
2. Also, it is part of the membrane system found throughout the cell's cytoplasm, even though its density is considered to be higher in some places, such as near the nucleus.
3. It is also is connected to the nuclear envelope or membrane
Some of its functions include
1. It produces antibody in certain leukocytes
2. It produces insulin in pancreatic cells
Hence, in this case, the correct answer is Option D "all of the above."
Speed = distance ÷ time.
1864/42=44.38
The correct sequence is option (c)
All the living organisms in the world responds to the environmental conditions and that condition could be temperature, pressure, etc. The changes in the environmental conditions are first observed by the cells of the body and then by the tissues and then from tissues it gets transferred to the organ then to organ system and finally the organism responds to the change.
There are mountain ranges in the middle of the ocean floor. Because of the higher elevation gravity pushes down on the edges of the plates. This is called ridge push.
<h3><u>Explanation:</u></h3>
Ridge push is a simple explanation of the height of the landforms based on the gravity and the elasticity of the underlying rock. It says when a landform gets too much higher, the weight of the overlying rock and soil pushes the landform back to plains. Thereby an equilibrium is maintained.
Slab pull is a theory proposed which visualizes the earth interior as a pool of hot molten lava that has a convection current going on. It explains why the crust of the earth continuously moves slowly and forms mountains and other rift valleys.
