Answer:
The cells wouldn't be able to photosynthesize
Explanation:
Chloroplasts absorb light energy, enabling photosynthesis. if they are damaged then the plant can't get light energy.
<span>What did Jean-Baptiste Lamarck believe about traits such as large muscles that are acquired during one's lifetime?
</span><span>They can be passed on to offspring.
</span>
<span>Jean-Baptiste Lamarck proposed that organisms have an innate tendency toward complexity and perfection.</span>
Answer:
When light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule
Answer:
not very sure what your question if you can upload again the question that will be great
The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
Action potential travels through the membrane of the presynaptic cell causing the voltage-gated 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 ACh binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
