Answer:
acetyl CoA
Explanation:
The starting molecule for the krebs cycle is acetyl CoA.
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy

High surface tension because of the attraction between water molecules helps bugs walk on the surface of the water.
<h3>How does surface tension help insects walk on water surface?</h3>
Surface tension is important for insects that walk on water. They would sink without it. When compared to air molecules, water molecules are more strongly attracted to one another. Due to cohesion, this makes them attract and cling to one another strongly in a body of water. The water molecules between the molecules at the water's surface are more strongly attracted to one another because they do not have water molecules surrounding them on all sides.
As a result, there is an inward force that forms a "film" at the surface and causes the water to act as though a thin membrane were covering it. Surface tension is the term for this phenomena.
Surface tension can be used to the advantage of some insect and spider species. They don't break the water's surface when they stand on it because their negligible weight is insufficient to dissipate the force of surface tension. Instead, they make dimples or indentations in the surface with their feet, which rebound to move the insect ahead. This enables them to move swiftly over ponds, lakes, and rivers in search of prey.
