Answer:
water act as a reactant in light reaction.
Explanation:
Water undergo hydrolysis in presence of sunlight to form proton(H+) and hydroxyl ion(OH-) ion. The OH- ion liberates electron to reaction center of photosystem 1 thereby exciting the later .The excited photosystem then donates that extra electron to the primary electron acceptor and from the primary electron acceptor the electron moves through various electron carriers to generate ATP .
Basically water act as reducing agent in photosynthesis process.
Not having enough energy within the cells, injury and/death could occur.
Asbestos, tobacco smoke, and formaldehyde are a few common examples
Answer:
Coronary Artery
Explanation:
A blockage by blood clot formation is coronary artery called as thrombus reduces the blood flow to the heart. The reduced blood flow causes the heart to dysfunction and the myocardial infarction occurs. Heart tissue can sustain serious damage upon such a shock.
The correct answer is A. Melting
Explanation:
Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.
This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.
