Why do plants change colors?
Chemical changes.
The purpose of the cytoplasm is to?
Is where the chemical changes of the cell happen
Secretion of these are regulated by signals from the nervous system and chemical changes in the blood?
Hormones
How are biomass fuels and fossil fuels alike?
All the chemical changes are the same.
Could chemical digestion take place if mechanical digestion did not occur?
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
How energy from the Sun changes to chemical energy in plants and to mechanical energy in animals?
through the exylem and then leaves
What energy does an automobile have that changes into mechanical energy?
chemical
Mechanical and chemical weathering changes the earth's?
Crust.
Mechanical and chemical weathering changes the earth and?
Crust.
What is the study of chemical pathology?
Chemical pathology studying the relation between diseases and chemical changes involved.
What types of weathering that does not cause chemical changes?
mechanical weathering
What kind of energy do you get from a lawn mower?
Chemical energy changes to heat energy, which changes to mechanical energy.
How are machanical and chemical weathering different?
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
Weathering that does not cause chemical changes is called?
It is classified as physical or mechanical weathering.
Does mechanical weathering change a rocks chemicals?
No, not at all. Chemical weathering changes the molecular composition of minerals, but mechanical weathering only changes its shape or outward appearance.
What happens when you turn on a battery operated toothbrush?
Chemical energy changes to electrical energy which changes into mechanical energy
What happens when you turn on a battery-operated toothbrush?
Chemical energy changes to electrical energy which changes into mechanical energy
