Biology
1 answer:
astraxan [27]3 years ago
6 0

Answer:

Chemical bonds contain potential energy.

Explanation:

Chemical bonds always contain potential energy. The atoms of the bond want to move to a lower energy to become more stable.. The energy for breaking bonds only comes when stronger bonds are formed.  This energy is used to tear apart the bonds holding the Hydrogen atoms together. The strength of the covalent bonds depend on the overlap between the valence orbitals of the bonded Atom.

shepuryov [24]

Answer:

end of cytokinesis

Explanation:

Telophase is the last stage of cell division. It ends with cytokinesis which is the splitting of the mother cells into two daughter cells. The cell pinches in the equator region with the help of a ring of contractile protein filaments. The formed cleavage furrow grows until the two cells pinch off completely.

A food shows many food chains within a community and how they overlap.
3241004551 [841]

Answer:

The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.

For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.

Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
