Answer;

The above statement is true

Evidence may be placed into containers like manila envelopes, plastic pill bottles, plastic bags, and carefully folded paper.

Explanation;

It is important that evidence be collected, handled, and stored in a way that will ensure its integrity.

Appropriate packaging depends on the type of evidence, the condition of the evidence, and the laboratory examination(s) requested.

Therefore, using packaging that is appropriate for the specific type of evidence, such as paper bags,envelopes, plastic bags (for non-biological evidence), cardboard boxes, metal cans, glass jars, etc, is really important.

the second type of galaxy is called a barred spiral, which has a thing called a bar straddling the nucleus

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
