Which description explains why there are two high and two low tides in a day? (4 points)
SCORPION-xisa [38]

Answer:

Earth rotates in and out of a tidal bulge twice a day.

Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.

The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Hope it helped!

Researchers have noticed that some men who were sterile because their sperm cells were unable to move also had chronic infection
zimovet [89]

Answer:

Kartegener's disorder

Explanation:

The respiratory tract has cilia which move. Sperms also have a tail that moves. They both have the same protein in their structure called microtubules. There is a disorder in which there is the absence of a part in the microtubule. Dynein arms absent in microtubules. Because the respiratory system and sperm both contain cilia that's why these two systems have a connection and not work properly.
