Answer:
The vessels draining Myocardium of the heart join to form <u>Coronary Sinus </u> that ultimately opens into <u><em>THE RIGHT ATRIUM.</em></u>
Explanation:
<u><em>CORONARY CIRCULATION:</em></u>
The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.
<u>Coronary Arteries</u> supply oxygen rich blood to the myocardium and <u>Coronary Veins</u> remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.
It’s the first one for sure
The correct answer is option D The population of foxes would probably decrease.
A food chain can be defined as a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. Each level of the food chain is called the trophic level. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the terrestrial food chain given above, grass → rabbit → fox, the decrease in the any population will effect the other organism at a different trophic level of the food chain. A sudden decrease in the population of rabbits will decrease the population of the foxes at the next trophic level as it is a secondary consumer feeding on the primary consumer which is the rabbit. So, a sudden decrease in the rabbit population will starve the foxes and thus decrease their number in the island.
<h2>Answer:</h2>
The correct answer is option A which is, "Electrons are re-energized to be used in NADPH production".
<h3>Explanation:</h3>
In photosystem II, light energy is used to split water molecules which release electrons.
These electrons then move to photosystem I to reduce NADP to NADPH.
Hence electrons in photosystem II are ultimately used to produce NADPH and option C is the correct statement.
A would be the correct answer.
The temperature is going up thus creating the theory that bacteria grows faster in higher temperatures or lower temperatures.
