What do prokaryotic and eukaryotic cells use to turn certain genes on or off?
Proteins
Why can liver cells create enzyme and heart cells cannot?
because the liver cell uses different genes than the heart cells use
Use the big idea cells to explain variation?
use cells like your genes and explain how you inherited your characteristics and the environmental characteristics
How many genes needed to code one protein part into a protein such as hemoglobin?
4 by the way i just guessed this so dont use it.
How might life be different if cells had to use active transport to move every substance?
Life would be very difficult and processes would drag if cells were to use active transport to move every substance to its destination.
Why would someone use or need gene therapy?
To replace faulty genes in the cells of the body, especially where the concerned gene is functional, most used, or can replicate the genes when making new cells (such as blood cell production). There is not much point in replacing genes in every cell of the body, even where that gene not used, hardly used, or will die after a short life and not be able to spread the genes to future daughter cells.

Do all body cells activate the same genes?
All body cells have the same genes except for the sex cells (sperm and ova). They do not use the same genes. A muscle cell isn't using the same genes as a nerve cell does. Otherwise the muscle cell and the nerve cell would not be different nor do different things.
How do nerve and muscle cells differ from other body cells?
nerve cells transfer data and feelings such as pain to the bain to be processed. other cells are practicly independent and use their own nucilus to do the processing, however much there may be.
Which cells in organisms use energy released from glucose?
Every cells both make the ATP and use it.
How do some cells become brain cells and other cells skin cells?
by specialization
Why can't I get a tan?
its in your genes...but to be safe, dont tan to prevent skin cancer. instead use a self tanner.
When do cells make protein molecules?
Cells use genes to make proteins for critical jobs like carrying oxygen and contracting muscles. This is called protein synthesis.
How can cells have the same DNA?
Although all calls have the DNA only some parts of it are turned on different cells (this is called gene expression). Which genes of the DNA are turned on determine the functions and kinds of cell. Even in the same kinds of cell genes can be differently expessed depending on what the cell needs to do at the time. If you have a drink of alcohol for instance a whole bunch of genes turn on in the liver to detoxify the alcohol. When you have meal hundreds of genes in the stomach, intestine and blood stream kick into action to digest the food and send it away for storage or immediate use. Cells have many things that regulate gene expression some things turn genes off or down others turn them up or on. There are factors turn on whole cascades of genes.
Reproduction by mitosis duplicates?
Haploid cells use mitosis for asexual reproduction..Meiosis is used in animal cell division to create haploid cells for reproduction
