The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
There are many billions of nerve cells, also called neurons, in the nervous system. The brain alone has about 100 billion neurons in it. Each neuron has a cell body and various extensions. The shorter extensions (called dendrites) act like antennae: they receive signals from, for example, other neurons and pass them on to the cell body. The signals are then passed on via a long extension (the axon), which can be up to a meter long. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
Answer:
Well, by my reckoning, the first sentence they are putting Ralph on a sort of condition, not a way of reasoning.
The last one they try to intimidate Freddy comparing him to a coward.
The letter B sounds better. The speaker says something positive to Maryann, making her come up with a sense of being brave and make a good decision.
But, as I said before, it's just what comes to my mind. Let's wait for any other explanation. :)
Explanation:
Answer:
The correct option is
Option (E) All the choices are membrane - bound organelles.
Explanation:
The membrane bound organelle are -
( A ) Lysosome - have digestive and destructive membranes .
( B ) Golgi apparatus - are membrane bound , and are responsible for transporting and modifying lipids and proteins .
( C ) peroxisome -
It is a membrane - bound organelle present in the cytoplasm of the cell, it plays a key role in the oxidation of some biomolecules.
( D ) Endoplasmic reticulum - is a membrane bound organelle , present in the cytoplasm , it usually has ribosomes on its outer surface , which helps in protein and lipid synthesis.
Hence,
all the mentioned organelles are membrane bound,
correct answer is ( E )
