The liver, pancreas, and lining of the digestive tract come from

The liver, pancreas, and lining of the digestive tract come from: the endoderm.

Explanation:

To understand this question we need to analyze it and then find the association between them. So, we are talking about different body parts. We have two organs and one organ part. All of them are organs involved in the absorption of nutrients, and the association looked is composition.

We have 4 options:

Endoderm: Which is one of the major germ layers in the body. It is a cell tissue characterized by a soft and fragile surface that in our body builds the pancreas, liver and the inner layer of the gastrula. So this is the correct answer.

Ectoderm: It is one of the three major germ layers, it is represented as a hard and strong body tissue that protects the inner tissue and systems. Like the skin and neocortex. So it's wrong.

Neural crest cells: Is a subtype of ectoderm cell layer that provides protection to early state embryo bones and cartilage. So it's wrong.

Mesoderm: is a germ layer that arises during granulation and is also presented in the ectoderm contributing to the bone structure and central nervous system cells.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
