dmitriy555 [2]

The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.

The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.

Explanation: In medicine, the practitioners divide the lower part of the body known as the 'abdomen' with imaginary lines ( one vertical and one horizontal) to form the 'Quadrants' and (two vertical and two horizontal) the 'Regions'. The Quadrants are divided into four main parts:

1) Left Upper Quadrant (LUQ)

2) Right Upper Quadrant (RUQ)

3) Left Lower Quadrant (LLQ)

4) Right Lower Quadrant (RLQ)

The regions are divided into nine parts:

1) Left Hypochondriac Region

2) Right Hypochondriac Region

3) Epigastric Region

4) Left Lumbar Region

5) Right Lumbar Region

6) Umbilical Region

7) Right Iliac/Inguinal Region

8) Left Iliac/Inguinal Region

9) Hypogastric Region.

The abdomen is divided into regions in order to help medical practitioners and students easily understand the abdominal area of the body as well as the human anatomy. It also helps them provide preliminary diagnosis and treatment based on pain emanating from each region or quadrant.

Chytrid ("little pot") refers to group of fungi with chitin cell walls, a posterior flagellum and absorptive nutrition. They reproduce with zoospores (motile asexual spores).
