These chemical processes require energy. The respiration and metabolism require adenosine triphosphate (ATP) which is cellular energy, and the organs get their fuel from the calories we consume. Without this energy, we eventually die
<span>The answer is B. Mesoderm.
During gastrulation three layers form. Ectoderm, mesoderm, and endoderm. Mesoderm is the middle layer and from that layer a multitude of tissues and organs develop. The mesoderm develops into connective tissues like cartlage, bone, blood, and blood vessels. The mesoderm can also develop into muscle types like cardiac, skeletal, and smooth.</span>
Answer:
Option D, Zinc is higher on the activity series because there is clear evidence of a reaction.
Explanation:
It is very clear that a metal which is higher in activity will replace a metal having lower activity.
Since, Zinc has higher activity than copper, it is very sure that it in a copper chloride solution it will replace copper and produce zinc chloride solution leaving behind copper as residue.
Residues of copper is a clear evidence of reaction
The chemical equation for this reaction would be -
Hence, option D is correct
Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as 'clastic' sedimentary rocks); by the accumulation and the consolidation of sediments
