Answer:
The need for continental time zones stemmed directly from the problems of moving passengers and freight over the thousands of miles of rail line that covered North America by the 1880s. Since human beings had first begun keeping track of time, they set their clocks to the local movement of the sun.
On the laboratory bench right in front of you, there is a bone. You can tell that it has an articular surface that is smooth and just slightly concave. This skeletal feature would be referred to as a Facet.
<h3>What is the composition of human bone?</h3>
A transcription factor collagen forms the structure of bones, and calcium phosphate, a mineral, gives the framework strength and hardness. When other body parts require calcium, bones release some of the calcium they have stored into the blood.
<h3>Why are bones so durable?</h3>
A living, developing tissue is bone. Collagen, a polypeptide that provides a soft structure, and calcium, a mineral that gives strength and hardness, make up the majority of its composition. Together, these factors give bone the strength and flexibility it needs to withstand stress.

Here is more about your questions:
The pelvis is a good identifier when it comes to male and female because the features have distinct features. The female pelvis for example is broader and the inlet is much wider. It is structured that way to prepare the woman's body for pregnancy and child birth.
Forensic anthropologists is a sub-category of anthropology. Forensic anthropologists examine skeletal remains to determine how an individual lived, died, and how long they were dead. They can also identify who they were. Forensic anthropologists can assist especially when the remains are badly decomposed.
Answer:
Answered below.
Explanation:
The fossil records are beneficial in giving us. wide range of knowledge about fossils but sometimes these records are flawed, in that they are incomplete or misleading.
Many of the fossil records available are incomplete because some animals tend to decay within a short period of time due to their soft tissue. Also some are destroyed due to the movement of tectonic plates over time.
Another flaw scientists encounter is that there are no fossils which illustrate or represent the orderly transition from one organism to another. Fossils generally do not support the Darwinian theory of evolution as no evidence is found of ordered, sequential transition from simple to complex life forms as postulated.
These flaws are significant because they influence our knowledge and understanding of life forms and evolution.
