Answer:
Yes
Explanation:
A phase change does not change the chemical make-up of a substance. Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance. Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds. That stays the same whether the water is solid (ice), liquid (water), or gas (steam). The chemical structure of water does not change as it goes through the different faces. It's still water. What does change is the speed at which the molecules move and how far apart they are as a result. Water vapor consists of molecules moving quickly and at random. As temperature drops, water molecules slow down. Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.
Answer:
A. They have the same function
B. They have evolved independently
C. They indicate an evolutionary relationship
Explanation:
- Analogous structures are structures with a different embryonic but have evolved to perform similar function.
- <em><u>Analogous structures are a result of convergent evolution which is the independent evolution of similar features in species of different lineages or different embryonic origin.</u></em>
- Examples of analogous structures include; wings in flying animals like bats, birds, and insects, and fins in animals like penguins and fish.
Answer:
The correct answer is chemical energy from broken bonds is transformed into mechanical energy.
Explanation:
Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.
The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.
