Answer:
Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
The father's phenotype(physical trait) is wet earwax and the mother's phenotype is wet earwax as well.
Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
The answer to this should be C.
Given what we know, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would <u>not change</u> during its trip.
<h3>Why would the truck have the highest gravitational attraction?</h3>
This has to do with how we calculate gravitational attraction. To summarize it greatly, this value is directly proportional to the mass of the object in question. The <u>more </u><u>massive </u>the object, the <u>more </u><u>gravity</u> it will produce. Therefore, since the semi-truck is the largest, it will have the greatest gravitational attraction.
<h3>Why does only the mass of the spaceship remain constant?</h3>
This has to do with the relationship between each value and the situation described. The acceleration and velocity will change as the ship loses fuel and is affected by the gravity of the earth and moon. The weight of the ship is also affected by gravity, whilst the mass is a physical property that <u>does not depend </u>on any of these and therefore <u>does not change</u>.
Therefore, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would not change during its trip.
