It is a physical change: the wood (mostly cellulose) is not changed by the breaking. However, the living cells (if any) in the branch will begin to change chemically when exposed to the air and cut off from the xylem and phloem in the rest of the tree. Eventually the cells will die and the wood will rot (chemical changes).

Why are electrodes applied to the fleshy part of a limb?
Electrodes are placed on the fleshy part of a limb to ensure good electrical conductivity and contact with the muscle tissue. This placement helps to accurately measure and stimulate the muscle activity during electrotherapy or biofeedback sessions.
Which limb sensor is the reference or ground electrode?
In limb leads (I, II, III), the reference or ground electrode is typically located on the right leg. This electrode is used as a common point of reference for measuring electrical activity in the heart.
Why light sensitive polymers used in plasters?
Light sensitive polymers in plasters are used to provide a visual indication of when the plaster is fully cured. These polymers change color when exposed to a specific wavelength of light, allowing healthcare professionals to easily monitor the curing process of the plaster. This technology helps ensure that the plaster is fully cured before allowing the patient to use the affected limb.
Is CaCi2 ionic or covalent?
I'm going to go out on a limb here and assume you meant to put CaCl2 rather than CaCi2. (since, to my knowledge, there is no element with the symbol Ci). CaCl2, Calcium Chloride, is ionic. When trying to determine if a chemical bond is ionic or covalent, you have to determine the difference in the electronegativity of the two atoms involved. Ca (Calcium) has an electronegativity of 1. Cl has an electronegativity of 3.16. The difference is 2.16. As a rule of thumb, a difference greater than 1.9 (some sources online may vary slightly) tells you that the bond is ionic. What this basically means is that the electrons that are being 'shared' to form the bond between the two atoms, really spend MOST of their time around the atom with the higher electronegativity. Keep in mind that electronegativity is a measure of an atom's affinity for an electron. Basically, how much pull that atom has on the electron. The higher the electronegativity, the greater the pull. So, when you put such an atom in water, the two atoms come apart with one of the atoms LOSING an electron to the other atom which then has an extra electron. Thus one of the atoms ends up being positive and the other ends up being negative. I hope this helps.
What is the organic compound composed of a carbon chain with hydrogens attached and an acid group at one end and a methyl group at the other?
If by 'acid group' you mean a carboxyl group (COOH), and by 'methyl group' you mean the carbon is right at the end, then it isn't really a methyl group, just a normal carboxylic acid2 carbons: Ethanoic Acid, CH3COOH3 carbons: Propanoic Acid, CH3CH2COOHIf the methyl group was in the middle. The number of carbons here includes the methyl group, but note the name of the chemical doesn't correspond to the total number, but by the longest chain possible.4 carbons: 2-Methylpropanoic Acid, CH3CH(CH3)COOH5 carbons: 2-Methylbutanoic Acid, CH3CH2CH(CH3)COOH3-Methylbutanoic Acid, CH3CH(CH3)CH2COOH
Is yeast causing bread to rise is a physical or chemical change?
Yeast rising bread works because yeast (an organism) converts starch to carbon dioxide which makes bread grow. This can be seen as a chemical reaction (yeast converting starch to CO2 gas) or a physical reaction (the CO2 making the bread expand).
How many limbs has horse if one limb break?
a horse has three after the breaking of limb
Is a broken limb and inherited trait?
No, a broken limb is not an inherited trait. The likelihood of breaking a limb can be influenced by factors such as lifestyle, activities, and environmental conditions, but it is not directly determined by genetics.
Can you undo a physical change?
Explain physical change: Plastic Surgery- Sometimes, but more oft then not.. No. Body features and physical appearance from current- yes, you can lose weight or gain weight according to exercise and diet and other factors. you could change eye color by contact lenses or whiten your teeth. you could change your hair style and life style. Some things cannot be undone- like.. you cannot undo undoing your virginity or chopping off a limb. (good luck with that!!)
What does the energy come from that enables you to breathe and think?
I'm going to go out on a limb here and say food.
What are baseball player Limb McKenry's physical stats?
Limb McKenry is 6 feet 4 inches tall. He weighs 205 pounds. He bats right and throws right.
How do you say cut you from limb to limb in old English?
Perhaps the expression you want is "limb from limb" and not "from limb to limb."
What physical problems prevent enlistment to marines?
Some obvious physical problems would be being paralyzed or missing an arm, leg, or other limb.
How did the average hind-limb length of each island's lizard population change from that of the original population?
The average hind-limb length of each island's lizard population change form that of the original population because of adaptation.
Why is right arm stronger than left?
You do physical work with your right limb. So you do more exercise by your right arm. So your the right arm or limb becomes stronger than left.
How do you support individual with its use artificial limb?
To support an individual with the use of an artificial limb, it is important to provide proper training on how to use and care for the limb. Regular follow-up appointments with a prosthetist can help ensure the limb is fitted correctly and adjustments can be made as needed. Encouraging the individual to engage in physical therapy can also help improve their strength, mobility, and overall function with the prosthetic limb.
What physical property of the sun is responsible for limb darkening?
Limb darkening in the Sun is mainly caused by the decreasing temperature gradient from the center to the limb of the solar disk. This means that the outer regions of the Sun appear darker than the center due to their lower temperatures.
