Answer:
Explanation:
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment
Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers.
One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. Cells are suspended in a fluid environment. Even the cell membrane is fluid. ... By allowing some materials but not others to enter the cell, the cell membrane acts as a gatekeeper.
The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration; this process continues until the substance is evenly distributed in a system.
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy
I am thinking the answer is C. Hope this helps
Answer:
300L
Explanation:
So basically 3.9 L is equivalent to 3900 Kg of glucose and when u minus 3900 to 144 is basically 3000 which is 300L
Neurotransmitter has to be consumed in the diet is not the criteria for neurotransmitter. So the correct option is a.
A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. These signals enable you to move your limbs, experience sensations, maintain heartbeat, as well as receive and process all the information your body receives from other internal body parts and your environment.
These signals enable you to move your limbs, experience sensations, maintain heartbeat, as well as receive and process all the information your body receives from other internal body parts and your environment.
The axon terminal, a component of the neuron, is where neurotransmitters are found. They are kept inside synaptic vesicles, which have thin walls. Numerous thousands of neurotransmitter molecules can fit inside each vesicle.
