Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.
2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.
3 In the event that people drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.
4 De-elimination could be a major advance forward for hereditary designing.
There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.
Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling
im not sure if im right or if this is even close but i hope this helps of it doesn't i am so sorry

An area that has been sampled to have a large population of organisms. Does this represent high biodiversity? Why or why not?
An area that has been sampled to have a large population of organisms is
regarded as having a high biodiversity.
Biodiversity is defined as the condition in which areas have a high amount
of plant and animal species present there. Any place with a large population
of organisms is said to have a high biodiversity while places with low
population of organisms have low biodiversity.
The stated facts therefore makes an area that has been sampled to have a

why are different leads are used to measure the ECG
Different leads are used to measure the ECG simply because each lead is recording the electrical activity of the heart from a different direction
Each individual lead's ECG recording is slightly different in shape. This is because when the electrical activity within the heart travels towards a lead you get a positive deflection.
ElectrocardiogramAn electrocardiogram (ECG) is a simple test that can be used to check the heart's rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats

Answer:
In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low pO2, high pCO2, high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. This clearly indicates that oxygen gets bound to haemoglobin in the lung surface and gets dissociated at the tissues
