Investigators have arrived at a crime scene and are ready to search for evidence. What needs to happen next?
denpristay [2]

Answer: C . They should map out a grid to systematically look for evidence.

Explanation:

As a crime has been committed, the investigators do not need a search warrant so there is no need to ask a Judge for one so option A is incorrect.

It is best if evidence is searched for in different locations not just the primary scene so option B is incorrect.

Setting up a grip to enable the systematic analysis of evidence is their most likely course of action so option C is correct.

Even if the case is not complicated, evidence still needs to be searched for so option D is wrong.

Which option is a balanced equation for photosynthesis? A. CO2 + H2O &gt; C6H12O6 + O2 B. 6C6H12O6 + 6O2 &gt; 6CO2 + H2O C. C6H1
Karolina [17]

The answer is; D

A balanced equation is one that observes the law of thermodynamics on the conservation of matter and energy. Matter or energy cannot be created or destroyed but can only be transformed.

In this equation, therefore, the number of elements on the right side of the equation should match those of the left side. Of the choice equations, this is a balanced one; 6CO2 + 6H2O --> C6H12O6 + 6O2 and one that reflects the process of photosynthesis.

Nanofossils are microscopic fossils which are remains of calcareous nannoplankton, coccolithophores from various eras

Trilobites were common during the Paleozoic Era (540 to 245 mya); about half of the Paleozoic fossils are Trilobites. Trilobites evolved at the beginning of the Paleozoic Era and went extinct somewhere in the late Permian period which was 248 million years ago
