Answer: Because of reduced blood supply

Explanation:

The normal heart has low pyruvic acid to lactic acid ratio which shows the heart is working properly and has no problem in it.

The heart with low pyruvic acid to lactic acid ratio shows that it has some respiratory problem and does not have adequate oxygen supply.

Even the person having  very low  pyruvic acid to lactic acid ratio shows respiratory problem.

<em>b. wildfires</em>

<em>b. magnified the greenhouse effect</em>


The first blank is pretty simple; if lightning (electricity) strikes something flammable, like a forest, a fire is sure to ensue. This fire will obviously spread to the other trees and cause a massive wildfire.

The second blank is the greenhouse effect. The greenhouse effect is said to have caused our warming climate, which makes sense because heat from the sun gets trapped in our global "greenhouse", or the lower atmosphere. Lower atmosphere is key here because a large event like a massive wildfire can add some more heat to the atmosphere and contribute to this effect. A wildfire may seem like a minor event on a global scale, but it will do more damage to the atmosphere than you think!

<u><em>So answer A. Is the correct option.</em></u>

Calcium plays the most important role in structure formation of plants. Also act as messenger molecule in signaling. Deficiency  of calcium caused wilting , weakened stem and ultimately death of plant.

Magnesium is the key element in chlorophyll molecule. It is necessary for chlorophyll formation.

Sulfur is another very important element in plant life, it is necessary for protein synthesis in plants.

Phosphorous plays an important role in  process of cell devision , photosynthesis and respiration.
