What is the function of mitochondria in cells

Producing energy.

What do eukaryotic cells have that prokaryotic cells do not

Membrane enclosed organelles

What is an example of a physical rather thana chemical change

Which of the following is an example of a physical rather then a chemical change? Which of the following is an example of a physical rather then a chemical change?

Which of the following is an organic molecule

Glucose

CH4 for bio sem 1

Sucrose

Fructose
CH4

{Apex Asnwers} C2H6

The goal of basic science is

to teach you basic fundimentals of biology

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 is the basic function of a cell membrane

The basic function is to control which substances enter and leave the cell.

Which structure is found in both plant and animal cells

Mitochondria or ribosome

Which example involves a cell membrane receiving and sending messages

A tube worm retreating from a predator is an example of a cell membrane receiving and sending messages.

A cell tells other cells that danger is near. Cells of an organism tell each other when predators are near.

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

Which scientist studied how wounds heal and proposed that cells come from preexisting cells

Rudolf Virchow was the scientist who proposed the calls came from preexisting cells.

Which best describes a difference between prokaryotic cells and eukaryotic cells

Eukaryotic cells contain organelles that are enclosed in membranes

Which type of transport is responsible for oxygen entering into blood cells

Passive

Which scientist was responsible for disproving the theory of spontaneous generation

Louis pasteur
Louis pasteur

What was Rudolf Virchow trying to prove through his work

Spontaneous generation does not happen.

Which one is better for moving more nutrients in and out the cell surface or more volume

more volume decreases the surface area of the cell thus making the distance of transporting nutrients in and out of the cell less. so more volume is better

Due to an unusually high concentration of particles inside the cell the membrane starts to expand and burst. which problem is the cell most likely having

The cell is unable to maintain a stable internal environment

What do all cells have in common

They all Contain DNA

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

It is very selective about what it allows to pass through.

Which observation proves that a cell is a eukaryote

The cell contains a nucleus
