Why are organs made up of small cells instead of large cells

Organs are made up of small cells instead of large cells to allow the organs to be not easily harmed. This way if one cell dies or is attacked then the organ will not be damaged. If the cell was larger then the organ might not be able to recover.

What do bacteria have in common with the cells of other living organisms

They have ribosomes.They contain cytoplasm.

Some things bacteria have in common with cells of other living organisms is they both have chromosomes, they both have organelles and a nucleus, and are alive.

they have a cell membrane

What is the role of xylem in a vascular plant

Transports water and nutrients upwards

What causes fingers to look wrinkled after soaking in water

water enters the cells in the skin

Which best describes a difference between prokaryotic cells and eukaryotic cells

Eukaryotic cells contain organelles that are enclosed in membranes

What is the process of water moving from an area of low solute concentration to an area of high solute concentration

Osmosis is the process of water moving from an area of low solute concentration to an area of high solute concentration.

Why are embryonic stem cells useful for medicine

they are pluripotent

|APEX|

They can become more cells than adult stem cells can.

What factor most likely has the greatest effect on the number of molecules mitochondria can produce

The Speed of the H+ ions

What is true when two containers have different solute concentrations after osmosis occurs between the two containers

the consentration of solutes is the same everywhere.

Which describes a reason for making a prediction when doing a controlled experiment

To determine what sort of data table will be most useful

APEX;)

Which describes how background research helps in the design of an experiment

Background research helps in the design of an experiment because it provides information about why certain measurements are made.

What protein that allows ions to actively transport across

The transport protein allows substances to travel across the cell membrane. The substance is traveling from low concentration to a higher concentration. The process requires energy and is called active transport. The protein is simply called a transport protein.

What is a factor that determines whether molecule can cross a cell membrane

size/ polarity can be the factors

What is meant by the following statement The cell membrane is said to be fluid.

It moves sideways

A leaf cell has a very low concentration of salt. What would happen to the leaf cell if it were placed in a highly concentrated salt solution

Answer this question…

The cell would lose water, and the membrane would collapse
