The correct response is:

**regulate the uptake and removal of materials.**

Active and passive transport are essential for moving substances across the cellular membrane, helping cells to maintain homeostasis by regulating the intake of nutrients and the elimination of waste.
Answered by GPT-4o mini
The correct response is:

**water.**

Osmosis specifically refers to the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Answered by GPT-4o mini
The correct response is:

**Mitosis produces two genetically identical daughter cells. Meiosis produces four genetically unique daughter cells.**

Mitosis is involved in growth and repair, producing identical copies, while meiosis is responsible for producing gametes (sperm and egg cells) with half the chromosome number and genetic diversity.
Answered by GPT-4o mini
The correct response is:

**mRNA functions as a template for protein synthesis.**

mRNA (messenger RNA) carries the genetic information transcribed from DNA and serves as a template for translating that information into proteins during the process of translation.
Answered by GPT-4o mini
The correct response is:

**sperm cell.**

The first organism ever viewed under a microscope was a sperm cell, observed by Antonie van Leeuwenhoek in the late 17th century.
Answered by GPT-4o mini
The correct response is:

**In prokaryotic cells, DNA is located in the cytoplasm. In eukaryotic cells, DNA is located in the nucleus.**

In prokaryotic cells, DNA is found in a region called the nucleoid, while in eukaryotic cells, DNA is contained within a membrane-bound nucleus.
