The difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane
<h3>What is a cell?</h3>
A cell is the structural and functional unit of an organism which is capable of existing alone as it contains organelles that perform specific functions.
The plant cell is covered by a rigid cell wall which contains cellulose as its outer covering.
The animal cell contains not cellulose cell wall at its out covering but instead it is covered by a cell membrane.
Therefore, the difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane.

Answer:
The answer to your question is below
Explanation:
There are 4 types of chemical reactions:
- Synthesis is when two elements or compounds form only one compound.
- Decomposition is when 1 compound is broken into 2 or more products.
- Single replacement is when one element is replaced by another element.
- Double replacement is when the cations of two compounds are interchanged.
6.- Synthesis Al + 3Cl ⇒ AlCl₃
7.- Double replacement 2NaOH + H₂SO₄ ⇒ Na₂SO₄ + 2H₂O
8.- Decomposition Ni(ClO₃)₂ ⇒ NiCl₂ + 3O₂
9.- Combustion 2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O
10.- Single replacement Zn + 2HCl ⇒ ZnCl₂ + H₂
4 because barium is ionic and chlorine is covelent
Answer:
Model 1 represents the old geocentric model of the solar system and Model 2 represents the newer heliocentric model of the solar system.
Explanation:
Model 1 has earth in the center, therefore it is geocentric. the geocentric model of the solar system is old. Nobody believes in it anymore because it is scientifically inaccurate.
Model 2 has the sun in the center, therefore it is heliocentric. This is the newer model of the solar system.
