The unit of measurement in an ecological footprint is the global hectare.
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.
Coal is considered a non renewable source because the earth cannot replenish it.
The correct answer is B. competitive exclusion.
This law refers to the fact that it is nearly impossible for two species to exist in the same place at the same time together, if they are interested in the same resources. If both species need the same thing to survive, one will have to be stronger while the other one will dwindle in number.
Answer:
The relationship is that the greater the volume of water in the central vacuole, the greater the turgor pressure, due the more or less amount of water stored in the central vacuole.
Explanation:
As a consequence of the presence of a plant cell in a hypotonic extracellular medium, water passes through osmosis inside the cell, through the semipermeable cell membrane.
The central vacuole is a structure present in plant cells, whose main function is the storage of water. The amount of water present within the vacuole can cause this structure to grow larger or contract, which determines the turgor pressure, which is a phenomenon dependent on osmosis and hydrostatic pressure.
A central vacuole dilated by excess of water produces cell dilation which promotes increased turgor pressure and pushes the plasma membrane against the cell wall.
