Answer: Bonds between atoms break and new bonds form.

Explanation:

Bonds between atoms break and new bonds form. Chemical reaction is the rearrangement of atoms to form new substances. The bonds in the reactants first break so that atoms may be free to rearrange and form new bonds resulting in the products.

The best answer is 3

Bonds are made of energy. There are certain energy changes that occur during the making or breaking of bonds and this is called enthalpy changes. When a bod is broke, energy is required to break the bond, hence energy is taken in or absorbed when bonds are broken. This makes bond breaking an endothermic process.

Answer: Kingdom Animalia (Multicellular Heterotrophs)

Explanation:

Heterotrophs (animals) cannot make their own food like the green plant (autotrophic mode of nutrition). So they have to search for foods by moving about. They can feed in plants, other organisms /animals or feed on dead materials.

Animals are multicellular (with many specialised cells). For example the cell in our nose are meant to respond to smell while that of the eyes are specialised for light capture. Our muscle cells focused on movement. Unlike the plants, animals lack cell walls.

A man with Type A blood marries a woman with Type AB blood. According to predicted outcomes based on genetics, their children ma

DochEvi [55]

Well,

We need to make a Punnett square. Assuming that the man has type A, not AO or AA blood, we will have a 1 x 2 Punnett square. We just have to take the A on the left and pair it with either the A on the left column or the B on the right column.

Therefore, the percent chance of having an AA genotype is 1 in 2 or 50%, while the percent chance of having an AB genotype is 1 in 2 or 50%. Thus, the possible phenotypes are 50% A type blood and 50% AB type blood.

I have attached the resulting Punnett square.
