Answer: Chlorophyll
Explanation:
Chloroplasts contribute to the cell by housing the photosensitive pigment chlorophyll which is able to facilitate the conversion of light energy to chemical energy.
Answer:
The postsynaptic cell has many synapses with many presynaptic neurons
Explanation:
Spatial summation is a process of producing an action potential in a neuron with input from multiple presynaptic nerve cells. This process determines whether an action potential will be triggered upon reaching threshold from multiple synapses with presynaptic neurons. Summation of all inputs determines if an action potential will b generated.
Stem cells have the ability to replace damaged cells and treat disease. ... Stem cells, if they can be directed to differentiate into specific cell types, offer the possibility of a renewable source of replacement cells and tissues to treat diseases including Parkinson's, stroke, heart disease and diabetes.
The Answer is A) Nuclear power generates large amounts of power limited to projection of greenhouse gases.
I believe this is the answer. As per the reports in 1998, it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Nuclear energy by far has the lowest impact on the environment since it does not releases any gases like carbon dioxide, methane which are largely responsible for greenhouse effect. There is no adverse effect on water, land or any habitats due to the use of it. Though some greenhouse gases are released while transporting fuel or extracting energy from uranium.
Have a great day. Keep asking questions!
