Answer:
Model B
Explanation:
It let's more fluids flow through unlike Model A
Answer:
During photosynthesis the tree while convert the energy from sunlight into sugar (glucose). The xylem will transport the water to the leaves. The phloem will transport the glucose. The energy from sunlight will also be used to convert water and carbon dioxide into oxygen and glucose. Hence, the energy stored within the glucose/sugar molecules will be used to help the tree grow.
Explanation:
I wrote it in my own words but it will probably say i took it from go ogle since used similar terms apparently.
hope this helps and is right. p.s i really need brainliest :)
The correct answer is Individual.
Species is the basic unit of macroevolution.
We can term macroevolution as a large-scale change at the species level which results in the formation of new species.
Answer:
Enzymes are proteins made up of amino acids and acts as biological catalysts in our body. However, glucose serves the purpose of energy provider for metabolism which is not a protein.
Explanation:
The correct order is:
- Action potential arrives at the axon terminal.
- Calcium ions enter the axon terminal.
- Synaptic vesicles fuse to membrane of axon terminal.
- Acetylcholine is released into the synaptic cleft.
- Acetylcholine binds to its receptors on the junctional folds.
- Junctional folds become depolarized.
- Action potential is initiated on the sarcolemma.
Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell).
