Answer: The question is incorrect, below is the correct question
Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?
The correct answer to the question is option D
mtDNA (mitochondrial DNA) analysis
Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.
There are several methods of DNA fingerprinting as outlined in the options given with the question.
In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.
Answer:Human population growth impacts the Earth system in a variety of ways, including: Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.
Explanation:
By containing all the instructions for it to carry out it's life. Hope this helps! :)
The correct answer is option d. its absence would affect many organism present in the community.
The keystone species are the one, who play a very important role in the ecosystem. In case, the keystone species is wiped off from a particular ecosystem, then the function of the ecosystem would cease and lead to a major effect. Hence, the keystone species is very important for the survival of ecosystem.
The unacknowledged or inappropriate adoption of the customs, practices, ideas, etc. of one people or society by members of another and typically more dominant people or society.
