Answer:
D
Explanation:
the movement of your digestive system is through muscles within your wall that contract to push food down.
Peripheral proteins are held to the membrane surface primarily through electrostatic or hydrogen bonds.
The two kinds of unbalanced forces are:
- Net Force: Is the vector sum of all forces acting (pushing or pulling) on an object.
- Resultant Force: is a force that alone produces the same acceleration as all those forces.
To effects that unbalanced forces have on objects are:
- Can make an object move or stop.
- Can speed up or slow down an object.
Here are some examples:
- When falling out of a plane when sky diving, this is making you move faster. Then when you are using a parachute, you are slowing down.
- A man uses force to roll down an object from the top of a hill.
The term microevolution represents a predictive theory of how species might change with time.
The term macroevolution assumes that nature can create whole new structures and organisms simply be the environmental constraint.
Evolutionary biology, genetics, aetiology, genetics they overlap with the closely related sciences of ecology.
Ecology seeks to explain the movement of materials and energy through living communities, successional development of ecosystem and processes, adaptation and interactions.
