If the bill is counterfeit and the paper is wood-based, the iodine in the pen solution will react with the starch and leave a dark brown or black mark.
Answer:
1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable
Step-by-step explanation:
1. Available energy
Energy consumed = 1000 J
Less waste = - 177 J
Less respiration = <u>-784 J
</u>
Total energy lost = <u>-961 J
</u>
Available energy = 39 J
2. Percent of total energy usable
The chipmunk could use only 39 J of the original 1000 J.
% of energy usable = 39 J/1000 J × 100 % = 3.9 %
3. Percent of energy unusable
The chipmunk lost 961 J of the original 1000 J.
% of energy unusable = 961 J/1000 J × 100 % = 96.1 %
Answer;
b. Their ability to pass on genetic information.
Explanation;
-Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure.
-They exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings.

Answer:
C) Practicing good scientific method and practices.
Explanation:
The text states, "repeating the experiment multiple times," as well as other preparations that a good scientist uses.
Doing something multiple times over is a good sign of a good scientific method.
Taking careful measurements, having several researchers run the same experiment, and only testing one variable at a time are all good practices that a scientist should use.
