Answer:
Digestion, excretion and transportation of substances.
Explanation:
Chemical reactions such as breakdown of food, cleaning of blood and absorption of nutrients and digestion are the activities that our body done with the use of energy. Digestion of food needs energy for the breakdown of food with the help of several enzymes. Transportation of waste materials and other substances also needs energy. Our cells absorb nutrients with the help of energy molecules through active transport.
The answer is white matter in the spinal cord is called superficial tissue because it is located in the outer region of the brain and spinal cord.Myelin a protective coating for neural axons is made of lipid tissue that appears white on a freshly dissected brain.
The blank should be digestion (process).
The action of cutting food into smaller pieces with teeth is a physical change/digestion, because this action does not involve enzymes, which are necessary for chemical digestion, examples are such as turning starch to Maltose.
The action of cutting and crushing food can increase the surface area, so that it can speed up the chemical digestion later on and provide the most nutrients for the body.

Answer:</h2>
Genetic engineering
<h2>
Explanation:</h2>
Genetic engineering or recombinant DNA innovation includes the gathering of procedures used to cut up and consolidate hereditary material, particularly DNA from various natural species, and to bring the subsequent half breed DNA into a creature so as to frame new mixes of heritable hereditary material.
It is the base involved in production of hybrid species which has characteristics of different superior breeds. It has wide range of application in the field of agriculture and medicines. In agriculture, it is used to come up with crops that are resistance to pest and insect.
