Where are proteins formed? (Protein synthesis)
Name one of Newton’s Laws.
Newton's First Law: An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
Newton's Second Law: The acceleration of an object depends on the mass of the object and the amount of force applied.
Newton's Third Law: Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first.
What is the difference between a community and an ecosystem?
A community only contains living things, while an ecosystem has living and non-living things.
How are recessive traits displayed in homozygous are heterozygous organisms?
Recessive traits in homozygous organisms are displayed genotypically and phenotypically. (You can see the trait physically)
Recessive traits in heterozygous organisms are only displayed genotypically. (You cannot seen the trait physically, but it can be seen in offspring)
