The greatest current threat to the loss of the Earth's biodiversity is global warming. This is because when the ice melts, the cold comes down to us and makes us have rainy summers and very early snow and cold springs and cold autumns. And when the ice melts enough, water will start to come down and flood countries and cities, such as Manhattan. Scientists are predicting that California will break away from America.
In my opinion the answer would be A.
The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem. Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia.
The correct answer is A. Apoptosis is regulated cell death/suicide, not accidental.
Answer:
During photosynthesis, a green pigment called chlorophyll is required to absorb solar energy. The reaction in photosynthesis that requires pigments to absorb solar energy is called LIGHT REACTION.
Explanation:
Light reaction is considered to be the first stage or phase during photosynthesis and the key elements that is needed for the reaction to take place is- sunlight and chlorophyll. Chlorophyll is a pigment that makes the leaves of the plant appear green. There is also another important function of chlorophyll that is to trap solar energy during the process of photosynthesis to convert the trapped solar energy into chemical energy- ATP molecules. These ATP molecules then form glucose- food for the plant.
