200 seconds, or 3 minutes and 20 seconds.
1 km= 1000 meters
1000 meters divided by 5 meters every second, means that it’ll take 200 seconds to go that distance.
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 %
To proceed scientifically, you could measure several properties of the unknown liquid and compare them with the properties of known substances. You might observe and measure such properties as color, odor, texture, density, boiling point, and freezing point.

Answer: Cytokinesis
Explanation:This is the process by which the cell’s cytoplasm, and everything else in it, divides. That way, when the nucleus splits in two, there are two of everything in the surrounding cell to go with each nucleus. Once the dividing is complete, the plasma membrane closes around each new cell and pinches off, dividing the two new identical cells from each other completely. Immediately, both cells are in the first stage of the cell cycle (interphase) begins.
