<span>Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.</span>
Binary fission is for reproduction of a cell by division into two equals parts
A reinforcement schedule is a pattern that defines how often a desired response will be reinforced.<span>
</span>A variable-ratio schedule <span>is a schedule of reinforcement where a response is reinforced after an unpredictable number of responses.</span>
<span>Fixed-interval schedules on the other hand reinforce behaviors after set time periods.</span>
DNA microarray assays allow scientists to identify networks of gene expression across an entire genome.
The microarray is scanned to determine the expression of each gene printed on the slide after hybridization. The associated spot on the microarray turns red if a particular gene's expression is higher in the experimental sample than in the reference sample.
The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2. The chip is made up of a tiny glass plate that is enclosed in plastic. A few businesses use techniques resembling those employed to create computer microchips to produce microarrays.

The appropriate answer is c. global warming. Global warming is an increase in the global temperature caused by the increased use of fossil fuels. Using fossil fuels since the industrial revolution has pumped extra carbon dioxide in the atmosphere than what would actually enter from natural processes. This extra carbon dioxide is increasing the green house effect and causing the temperature to increase.
