Answer: Trash marks

Explanation:

The identification of the machine either photocopier or drum can be made by observing the defects over the copies generated through the machine. These defects are called as trash marks. These trash marks are because of the dust and dirt particles present inside the machine. They may also appear as a result of defect in the machine parts.

These particles can be seen as dark specks on the copy. If the suspect and the sample photocopied document have the same trash marks then this can be said that they have been generated from the same machine. The size, color, shape and groupings of these markings can be compared and matched to establish the link between the two or more comparable documents.

The crossing of a hybrid and a dominant purebred will always result in offspring which are what?

inn [45]

Answer:

Dominant

Explanation:

A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).

A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).

How would homeostasis be affected if the cardiac muscle stopped contracting?

vodka [1.7K]

The heart is a muscle, therefore, if the cardiac muscles stopped contracting, the result would be the ceasing of heart function. That would lead to death, as blood wouldn't be pumped throughout the body. Homeostasis would therefore be interrupted.
