Answer:
An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?
Acceleration= velocity/time
velocity=5mm= 0.005m
time= 1 hour= 60 seconds
A= 0.005/60
Acceleration= 0.000083m/s square
Explanation:
They are passed through reproduction
Explanation:
possible benefits of genetic engineering include:
More nutritious food
Tastier food
Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)
Less use of pesticides
Increased supply of food with reduced cost and longer shelf life
Faster growing plants and animals
Food with more desirable traits, such as potatoes that produce less of a cancer-causing substance when fried
Medicinal foods that could be used as vaccines or other medicines
