Answer: Option D " all of the above "
Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.
Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.
Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.
Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.
Hence, the correct answers are all of the above.
The answer to your question is alkanes
Answer:
The findings demonstrates an optimal foraging hypothesis based on maximizing caloric intake alone is probably incorrect in this case.
Explanation:
This example can also be explained by optimal foraging theory which helps in predicting the behavior of an animal which it is searching for food. Food provides energy to the animal but searching and capturing the food requires both energy and time.
So in order to maximize fitness , an animal adopts a foraging strategy which provides the most benefit which in this case is energy, for the lower cost and by maximizing the net energy gained.

Answer:
The use of the word "draw" here refers to the collection of blood samples for laboratory tests.
Step A - The first draw goes into the blood culture bottle or tube with a yellow cover.
Step B - This goes into the coagulation tube with a blue cover.
Step C - The next draw goes into the tube for non-additives. This usually has a red top
Step D - This features collection of blood into the tubes with additives. When dealing with additives, blood samples and additives it is important that the sample and additive is rigorously homogenized. This part can is broken down as follows:
- this goes into the SST tube. This tube contains a seperator and a clot activator and is usually is colour coded reddish-gray or gold top.
- This tube contains Sodium heparin and has a leaf green top
- This tube (PST) contains PST contains lithium heparin anticoagulant and a gel separator. It's cover is colour coded light green
- This tube contains Ethylenediaminetetraacetic acid or EDTA for short. It's cover is usually colour coded lavendar
- This tube is labelled ACD that is Acid Citrate Dextrose. It's top is coded light yellow
- this tube contains Oxalate/Fluoride and it's cover must be colour coded gray.
Cheers!
