Most coastal areas on Earth experience two high tides and two low tides every lunar day. What is a lunar day? Our days on Earth
ahrayia [7]

The correct answer is - C) 5:35 PM Friday.

The low tides occur twice in a lunar day, thus they are diurnal. The low tides appear when the Moon is between that point of the planet and the opposite of that point of the planet, thus in between, which is happening twice, on opposite parts of the planet.

Since the lunar day lasts for 24 h 50 m, we should just divide it in two, thus get 12 h 25 m. Than we should add the 12 h 25 to the time when one of the low tides appeared, which is 5:10 AM, so we will get 5:35 PM.

The low tides appear because the Moon is pulling the water upwards with its gravitational pull above the place where it is, so the side parts of the planet have their waters dragged away,thus resulting in the retreating of the water, known as low tide.

kondor19780726 [428]

Answer and Explanation:

A gene is a section of DNA. The change in the sequence of the DNA is known as mutation.  Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.

Answer - <span>C) Trees and shrubs provide shade, which keeps the water temperature cooler. Lower temperatures allow the water to hold more oxygen, which in turn creates a healthier habitat for the trout.</span>

Reasoning - The back story is if the water temperature is being changed. It will affect the trout indirectly warming the water. In turn if you have shades and shrubs to provide it for cooler areas it will preserve O2 a Certain Habitat for the Species.
