Cohesion known as water attraction to other water molecules is one of the major properties of water. liquid water has surface tension. this allows for insects such as water striders to walk on water. question number 3 the answer is because ice is less dense then liquid water because the water molecules for a new large structure as they cool down. of course Lakes freeze a course from top down even though the coldest areas are at the bottom. cold water begins to rises when it begins to freeze it accumulates at the top with a sheet of ice. the ice provides some insulation for the water below so that there is typically a significant portion of water under the ice sheet unless it's extraordinary really cold for a very very very very long time. if a lake froze from the bottom up they would more than likely freeze completely

zlopas [31]

<h2>D) option is correct </h2>

Explanation:

During citric acid cycle, Acetyl Coenzyme A is completely oxidized in form of CO2 and produce NADH, FADH2 and GTP (ATP)

Succinate is converted to fumarate with the help of succinate dehydrogenase and FADH2 is produced during this step

In the given conditions, if the amount of succinate is increased in comparison to malonic acid then it reduces the effect of malonic acid, therefore malonic acid will not be able to inhibit the conversion of succinate to fumarate and hence succinate will be the substrate and fumarate, the product in the reaction
