<span>mtDNA analysis is the best DNA technology to use. In DNA fingerprinting scientists run a gel electrophoresis of the subject's DNA in order to establish the banding patterns of the DNA fragments. People will always share half of their DNA with a parent. SO half of an individual's banding pattern will match half of their parent's DNA banding pattern. If someone is missing is found then scientists can compare the DNA fingerprint or banding patterns to see what the likelihood is of them being related.</span>
Answer:
Given that a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two calorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading.
Though consistent, the first colorimeter has a zero error of -5.
Hence whenever first calorimeter is used this adjustment to be made i.e. actual reading +5 should be made to get correct reading
But second can be used as such taking the reading as correct.
<span>Which of the following statements is NOT part of the cell theory?
a.) Cells are the basic unit of structure and function in living things
b.) All cells are produced from other cells
c.) Only animals are composed of cells
d.) All living things are composed of cells</span>
The answer is c
The telophase of the cell cycle chromosomes uncoil and the nucleus reappears. That is option C.
<h3>What is telophase?</h3>
Telophase is a stage of the cell cycle that occurs once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
During the telophase stage, chromosomes arrive at opposite poles and unwind (uncoil) into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears.
Therefore, the telophase of the cell cycle chromosomes uncoil and the nucleus reappears.

Overpopulation and food competence are the most important features for which a native species may cause important ecological damage.
<h3>What is overpopulation?</h3>
Overpopulation is a phenomenon in which a population of a given species is over-represented in the ecosystem, which may lead to important disturbances in the homeostatic equilibrium
The lack of homeostatic equilibrium may lead to extinction of competing species and act as a predator of organisms below in the trophic chain.
In conclusion, overpopulation is one of of the most important features for which a native species may cause important ecological damage.
Complete question:
The brown tree snake is native in areas such as Australia and eastern Indonesia. In those ecosystems, the brown tree snake is not causing the decline of bird or tree populations. So what makes this same species damaging in Guam? Identify some characteristics a species may possess that would fuel its ability to cause ecological damage, as the brown tree snake has in Guam. Provide some reasoning for why you chose these characteristics.
