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.

Artyom0805 [142]

Answer:

6 different forms of the protein could be made.

Explanation:

For the given nematode worm, 6 different forms of the protein could be made. This is because of the alternative splicing that will produce 6 kinds of mRNAs. We have 2 different forms for the exon 4 while we have 3 differen forms for the exon 7. Therefore, we have a total of (2*3) 6 different forms of the protein for the given nematode worm.

I need help with the 2nd part first gets brainlist
mixer [17]

Answer:

7. 4H₂O

Elements: Hydrogen, Oxygen

Number of molecules: 4

Number of elements: 8 H, 4 O

Number of Atoms: 12

Explanation:

The elements are determined by the their symbol i.e. H = hydrogen.

The number of molecules is determined by the coefficient ( the number in front of everything, in this case 4).

The number of elements is determined by the coefficient and the subscripts. Multiply the coefficient by the subscript after each element. When there is no subscript, it is equal to 1.  4H₂ = 4x2 = 8;  4O = 4x1 = 4.

The number of atoms is all the individual elements added together. 8+4 = 12.

KonstantinChe [14]

Explanation:

Carbon-12 atoms have stable nuclei because of the 1:1 ratio of protons and neutrons.

Carbon-14 atoms have nuclei which are unstable. C-14 atoms will undergo alpha decay and produce atoms of N-14. Carbon-14 dating can be used to determine the age of artifacts which are not more than 50,000 years old.
