Answer: I got you

Explanation: On islands around the globe, invasive European rabbits wreak such havoc on plants and seabirds that governments worldwide have spent a century trying to eradicate the furry beasts. Scientist Scott Pearson had come to this steep uninhabited pile of rocks to catalog the decline of the rhinoceros auklet, a gray seabird that nests deep in hollowed-out hillside burrows. But instead of spying one of the white-eyebrowed creatures, Hodum came eye to eye with the most likely cause of its decline. Rabbits inside the borrow.

Some problems with use of DNA analysis for forensic evidence may occur because of
alisha [4.7K]

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.

Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease
Gala2k [10]

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.

Use complete sentences to explain the advantage of using binomial nomenclature in the system of classification. Also explain wha
malfutka [58]
The advantage of using a binormal nomenclature in the system of classification is it formally names animals of a species of living things by giving a two-part name which either is based on Latin or other languages. One Part is used to classify the genus and the second part of the specific name. An example of this would be Homo sapiens (for humans).

Aside from the nucleus, where else can a small amount of dna be found in a eukaryotic cell?
mylen [45]

The nucleus is not the only source of DNA, besides it, DNA is also found in the mitochondria of all eukaryotic cells, as well as in the chloroplasts of plant cells and such DNA is called extrachromosomal DNA.

The DNA from the mitochondria (mtDNA) and chloroplasts are small and circular, which are similar to the prokaryotic DNA.

mtDNA contains its own genes that encode proteins that are part of the electron transport chain.

<span>Chloroplast DNA encodes for the components of the photosynthetic pathway.</span>
