Answer:
<u>A chemical bond between the phosphate group of one nucleotide and the sugar of a neighboring nucleotide holds the backbone together. Chemical bonds (hydrogen bonds) between the bases that are across from one another hold the two strands of the double helix together.</u>
Explanation:
<u>ANSWER:</u>
When a supergiant runs out of fuel, the object formed is either a black hole or a neutron star.
<u>EXPLANATION:</u>
- Supergiant are very large stars in the galaxy that end their lives very quickly.
- When a supergiant star loses its fuel, it blows itself by a supernove explosion.
- When supernove explosion happens, the supernova outshines other stars in the galaxy and then slowly faded away leaving a dense object called black hole or neutron star.
- This black hole or neutron star is surrounded by a mass of very hot gas and the elements of the supergiant star get scattered into the space.

Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.
<h3>What affects the speeds at which these objects fall?</h3>
- The falling speeds in both air and a vacuum will be the same for both objects.
- This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
- The same will occur in water if and only if the densities of the two objects are equal.
Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.

Answer:
describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides.[citation needed] Beach nourishment is typically part of a larger coastal defense scheme. Nourishment is typically a repetitive process since it does not remove the physical forces that cause erosion but simply mitigates their effects.
