Natural variation provided the phenotypes that natural selection then acted on, over time causing evolution
Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

Answer:
Tissues
Explanation:
Tissues are organized group of cells carrying out specific coordinated functions. They are organizational structures that lies between cells and organs. A group of cells binds together using specialized proteins forming a tissue, furthermore, a group of different tissues are the building blocks for organs and plant structures creating a complete system.
Answer:
Generally proteins are denatured at high temperature.Therefore when the egg is hard boiled they are denatured since eggs are protein, the 3-dimensional structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the orderly arrangements of disulphide bonds in proteins are disrupted , which results in the formation of inter chains bonds among disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption and formation of a macro molecule.
However, the addition of reducing agent , breaks the covalent disulphide bonds. While detergent breaks the interchain bonds among the disulphide bonds. (The noncovalent bonds),These combined effects untangled the mesh networks of polypeptides formed, and reduces the hardened nature,
Explanation:
That the hominids evolved with an increase in development within the womb and became more of a quality over quantity species
