The appropriate response is A. Gastrulation is a stage ahead of schedule in the embryonic improvement of most creatures amid which the single-layered blastula is rearranged into a trilaminate (three-layered) structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm.
Answer: Kingdom Animalia (Multicellular Heterotrophs)
Explanation:
Heterotrophs (animals) cannot make their own food like the green plant (autotrophic mode of nutrition). So they have to search for foods by moving about. They can feed in plants, other organisms /animals or feed on dead materials.
Animals are multicellular (with many specialised cells). For example the cell in our nose are meant to respond to smell while that of the eyes are specialised for light capture. Our muscle cells focused on movement. Unlike the plants, animals lack cell walls.
Through looking at layers of rock you can tell what kind of things transpired. If you find Fish fossils you can assume that at one point in time, there may have been a body of water of some sort. if you find certain plants, you can deduce that there was a forest or a grassy pasture. Or if there are variations in the layer you may be able to tell what kind of soil was there at one point in time, or maybe if there is volcanic rock, you could rightly assume there was a volcanic eruption at some point.
A reducing agent is an element or a compound that looses or donates electrons in a chemical reaction. The reducing agent undergoes oxidation (loss of electrons) in a chemical reaction. Bromine losses an electron and therefore it is the reducing agent while chlorine gains electrons and therefore it is an oxidizing agent.
