Answers

Answer 1
Answer: The answer is continental drift. 
Continental drift is the geological theory that explains how continents move through Earth's surface. All continents were once connected as one supercontinent Pangea. On that supercontinent, many related species, such as llamas and camels, lived together on one location. But after continents spread apart, related species were separated on different continents and adapted to different conditions

The _______ the time period during which a species lived and the _______ the distribution of its fossils, the better an index fossil the species is. shorter; narrower shorter; wider longer; narrower longer; wider

Answers

The index fossils have a shorter time period and wider geographical distribution of fossils.

What is an Index fossils?

An Index fossils refers to class of fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time.

They helped in the construction of geological periods that are commonly used today.

Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.

Therefore. the Option B is correct.

Answer:

Option (2)

Explanation:

Index fossils are defined as those fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time. They had great significance in the field of paleontology. It helped in the construction of geological periods that are commonly used today. It basically helped in forming the geological time scale. The age of the rocks in which these fossils were embedded is easily determined by using radioactive dating techniques.

Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.

Hence, the correct answer is option (2).

Which is an example of how latent evidence can be used to solve a crime?A. Clearly visible fingerprints on a knife are matched to a suspect.

B. The coagulation of blood near a victim indicates that death occurred two hours prior to discovery, when a suspect was reported at work.

C. A hidden fingerprint on a murder weapon did not match that of the suspect.

D. A forensic scientist concludes that tiny hairs found on a murder victim were not those of a suspect, but rather those of a dachshund.

Answers

"A hidden fingerprint on a murder weapon did not match that of the suspect" is the one example among the choices given in the question of how latent evidence can be used to solve a crime. The correct option among all the options that are given in the question is the third option or option "C".

Answer: C. A hidden fingerprint on a murder weapon did not match that of the suspect.

A latent evidences are those evidences which cannot be observed by the naked eye but requires specialized procedures to observe them and collect them from the scene of crime. These includes small plant evidences like spores, pollen, dust particles and latent fingerprints.

In the given question, the C. A hidden fingerprint on a murder weapon did not match that of the suspect is an example of how latent evidence can be used to solve a crime. This is because of the fact that latent fingerprints are those fingerprints which cannot be observed by naked eye but requires the use of powders, solutions to firstly develop them and then these can be collected by the tape lifting or other measure.
