Answer: Semi-permeable

Explanation:

The cell membrane are the semi-permeable membranes which are made up of proteins and phospholipids. The semi-permeable membrane causes some molecules or ions to pass through the membrane and protects the other to enter inside. This process avoids harmful ions and molecules to pass enter inside the cell and cause damage to the cell.  This process helps in maintaining the cell metabolism.

A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
DochEvi [55]

Answer:

Lunar eclipse

Explanation:

During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.
