Why is a microscope useful in determining the actual size of a specimen?
A microscope is useful in determining the actual size of a specimen because it magnifies the image, allowing for detailed observation of the structure and dimensions of the specimen. By comparing the magnified image to a calibrated scale, scientists can accurately measure the size of the specimen.
What are vntr?
VNTR stands for Variable Number Tandem Repeats, which are regions of a DNA molecule where a short nucleotide sequence is repeated multiple times. These repeat sequences vary in length among individuals, making VNTRs useful in DNA fingerprinting for identifying individuals or determining genetic relatedness.
Why are blowflies a useful species for forensic entomologists?
Blowflies are useful to forensic entomologists because they are among the first insects to colonize a dead body, laying eggs that hatch into maggots. The development rate of blowfly larvae is well understood, allowing entomologists to estimate the postmortem interval based on the age of the larvae. This helps in determining the time of death in forensic investigations.
Why can only certain parts DNA be used as DNA fingerprints?
The parts must be unique to the person.The parts must be unique to the person
How is dna and the gel electrophoresis method useful in science?
DNA and gel electrophoresis are useful in science for analyzing and separating DNA fragments based on size. This technique is valuable in molecular biology for identifying genetic variations, determining paternity, diagnosing genetic disorders, and conducting DNA fingerprinting. Gel electrophoresis allows researchers to compare DNA samples, study gene expression, and track the progress of genetic engineering experiments.
What is the most useful fact in determining whether two organisms are related?
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
How do you determine the useful life of a building?

Which hormone is most useful in determining whether the woman is pregnant explain why?
Human chorionic gonadotropin (hCG) is the hormone most useful in determining whether a woman is pregnant. This hormone is produced by the placenta shortly after implantation and its levels rise significantly in the early stages of pregnancy. Pregnancy tests detect hCG in a woman's urine or blood to confirm pregnancy.

When is pressure useful?
when determining volume, moles, weight, and/or temperature
What does the 'which' command do in Linux?
The "which" command returns the absolute path of the executable that is called when a command is issued. For instance, 'which firefox'. This is useful in determining whether you are using a locally compiled version or the distribution version of a program.
