Match each organ with the germ layer from which it is formed. mesoderm ectoderm endoderm

The correct answer would be- intestine: mesoderm, Bone: mesoderm and tooth enamel: ectoderm.

Explanation:

The three germ layers of form during the gastrula stage of the embryo development in triploblastic organisms. Every germ layer gives rise to different organism later in the development.

Ectoderm gives rise to the nervous system, tooth enamel, cornea and lens and epidermis and other.

Mesoderm gives rise to skeleton system, intestine, notochord, stomach and other.

The endoderm gives rise to the respiratory system, urinary system and other.

Thus, the correct answer would be- intestine: mesoderm, Bone: mesoderm and tooth enamel: ectoderm.

the correct answer is (

explanation:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
