Answer:
<em>Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out</em>
During the embryogenesis, three embryonic layers are formed. these aabryonic layers give rise to the different organs and structures. these three germ layers are ectoderm, mesoderm and the endoderm.
The endoderm layer give rise to primitive gut (digestive system) and its derived organs such as intestine, liver, pancreas. thymus, lungs, thyroid and prostate.
The mesoderm give rise to the muscles, bones, heart and the components of the circulatory system.
The ectoderm layer results in the formation of nervous tissue, brain and the skin, along with the receptors.
Hence, the pair <u>nervous-mesoderm</u> is an incorrect match, as the nervous tissue is derived from the ectoderm layer.
