Microscopic analysis is the most reliable method of matching hair samples to a suspect. True False
Genrish500 [490]

Answer:

The answer is <em>false</em>.

Explanation:

Although very popular in crime novels and TV shows, microscopic hair analysis isn't as reliable as it may seem. It was widely used during 1950-s and 1960-s as the best test to match a hair sample with the suspect, but modern tests proved it to be wrong. Microscopic analysis can give some information about the hair sample such as origin (human, animal or synthetic fiber), color, pigment distribution... For example, if the hair sample found was brown, and the suspect was black-haired, we could claim that he was Innocent. But if the found hair was black, does that mean that we could be absolutely sure that the suspect is guilty? Of course not, microscopic analysis can not provide evidence for that claim. On the other hand, the best method for matching biological samples, at the present time, is DNA analysis.

What is the correct order of the stages of speciation?
guapka [62]

First Stage: Separation

Speciation usually begins when a part of a population becomes separated from the rest of their species.

Second Stage: Adaptation

Adaptation in speciation is quite similar, though the groups may evolve different sets of traits if the environmental conditions differ for each group.

Third Stage: Reproductive Isolation

Reproductive isolation is when groups of a same species are reunited and cannot interbreed with each other anymore, so they are now identified as different species.

Which statements accurately describe how fructose metabolism in the liver differs from glucose metabolism?
laiz [17]

The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP.

Explanation:

Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.

After it is converted into trioses dihydroxyacetone phosphate as well as glyceraldehyde through aldolase.  With glucose metabolism Fructose get synergistic effect

Species adapt over time through structural and behavioral adaptations.

<span>plant moving toward light to increase photosynthesis

</span><span>Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.</span>
