The ribs form from the ________.<br><br> notochord<br> neural plate<br> neural tube<br> somites
Aleksandr [31]

Answer:

somites

Explanation:

Embryonic development looks like a chronometer. Next to the future spine, cells are differentiated with a certain spacing that scientists call "somites." These are structures that grow, change shape. Somites will give rise to vertebrae, ribs, and axial musculature.

Somites are transient epithelial structures. These structures form early in embryonic development and originate with other important structures in the vertebrate organism.

Consider the following chemical equation:
denis-greek [22]

<u>4NH3 + 5O2 → 4NO + 6H2O</u> is the correct balanced equation in the given chemical equation options.

What do you mean by Chemical equations?

A chemical equation is a written representation of the chemical reaction taking place between two or more substances. It can be written in words or symbols, and typically consists of the reactants (on the left side) and the products (on the right side). The arrow between them indicates the direction of the reaction.

The above equation is balanced because it has the same number of atoms of each element on both sides of the equation. The equation is balanced because it has 4 atoms of nitrogen (N) on the left side and 4 atoms of nitrogen on the right side. It has 5 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side. It also has 3 atoms of hydrogen (H) on the left side and 12 atoms of hydrogen on the right side.
