Answer: False

Explanation: as the muscles shortens due to contraction, the actin filaments from opposite ends of the sarcomere approach each other. So the two Z bands come closer with reduction in length of the sarcomere

Answer:

False

Explanation:

The Z-line is a structure formed between adjacent sarcomeres and is found at each end of the sarcomere in striated muscle and defines the lateral boundaries of the sarcomere, its function is to give anchorage to titin and to the outer ends of the thin filaments.  Due to this anchoring function, the Z-lines are responsible for force of transmission and during contraction, as the sarcomere shortens, the distance between Z lines lessens

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.
