On one side of the grand canyon could be a squirrel with a birth defect witch reproduses with a squirrel with normal genes. But the birth defect is stronger than whatever trait that may be. so the litter of squirrels mostly have this trait. and the cycle contiues
A virus is a tiny organism and may lead to mild-severe illnesses in animals or plants or humans.
Biologically we can term virus as a bit of RNA or DNA in a protein coat. It cannot replicate without another organism.
If we use an image of indicator, we may say yes virus is living. This is because the virus particle is non-cellular but has an NDA core.This core is enclosed in a protein coat and it has spike-like projections in all over its surface.
1. It is used to cure diseases that may harm or even kill us.
2. It is used to make transportation fast and easy.
3. It is used to understand the universe better to plan for the future.
4. It is used for fast and easy communication.
Make four different test groups.
Test 1: Add 10mL of A to 10mL of B, and insert substance X into the reaction. Record the time.
Test 2: Add 10mL of A to 10mL of B, and insert substance Y into the reaction. Record the time.
Test 3: Add 10mL of A to 10mL of B, and insert substance Z into the reaction. Record the time.
Test 4: This is your control group. Only add 10mL of A to 10mL of B, then record the time for the reaction to occur.
The catalyst is which ever substance caused for the reaction time to speed up. I hope that this helped! Please leave brainliest!
