I
can conclude that if the color of the solution in the control changed, the
control enabled me to have a perspective in which there is no change ought to
have happened. On the off chance that the control arrangement changed its
color, I would conclude that there were life forms in the water.

Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.
Explanation:
The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
A biologist whose interest lies primarily in the study of plants or animals can be called a naturalist, although these days it's more likely she'll be called a natural historian, a botanist, or a zoologist.
A cellular organelle is a structure in the cell that performs a specific function.
Nucleus - stores cell's DNA; DNA replication occurs here
Ribosome - produce protein; "factories" of the cell
Mitochondria - breaks down food for energy to be used by the cell; "powerhouse" of the cell
Vacuole - store materials such as food, water, sugar, minerals, and waste products
Endoplasmic reticulum - carry materials throughout the cell; "transport system"
