Answer:
1. to carry oxygen from the lungs to the body tissues
2. seven (7) or (4)
3.Humans can't live without blood body's organs couldn't get the oxygen and nutrients they need to survive,
Explanation:
No, this is false!
Renewable resources can be syntesized by humans, or not: some of them can, and some can't. This is not what makes them renewable, instead it's the fact that they will still be present in the nature after usage - they will be replaced (the sun will still shine tomorrow even if we harvest its power).
Grass I think Bc it’s not a living thing
Answer:
E) Certain environments can lead to an increased risk of developing certain diseases.
Explanation:
The lesson states that specific environments can increase the chance of health problems.
The behaviour of molecules in different phases of matter represents a balance between the kinetic energies of the molecules and the attractive forces between them.
All molecules are attracted to each other. At the same time, all molecules are in constant motion, and their kinetic energies increase with the temperature.
At very low temperatures, the kinetic energy of the molecules is low. The molecules cannot move fast enough to get away from the attractions of their neighbours. They are “glued” in place in a crystalline arrangement. The molecules are in the solid state.
At higher temperatures, the kinetic energy of the molecules is higher. The molecules will have enough energy to slide past their neighbours, but not enough energy to escape their attractions. The system is in the liquid state.
At very high temperatures, the kinetic energy of the molecules is so high that the molecules will be able to escape the attractions of their neighbours and move at will within the container. The system is in the gas state
