Answer:
An implantable cardioverter-defibrillator or automated implantable cardioverter defibrillator is a device implantable inside the body, able to perform cardioversion, defibrillation, and pacing of the heart. The device is therefore capable of correcting most life-threatening cardiac arrhythmias.
Explanation:
Answer:
You answer is B
Explanation:
This is the only possible answer because when animals die they might get trapped under layers of bone conserving the bone, and B is the answer because if bones are conserved in the sediment Scientists may be able to recognize certain animals for example, 1000 years ago a cow dies and is buried by sediment, the skeleton remains allowing scientists in the present year to analyze it, they might notice slight changes in things like the bones, or the teeth, etcetera, thus this is how Scientists found proof of evolution.
Answer:
The correct answer is - intrasexual selection.
Explanation:
Intrasexual selection is the act of competing with other members of one's own sex for various reasons such as high status, mating, area, and many more as well as the evolutionary process responsible for this competition. The great examples of these are antlers of deers and big size showy feathers of the peacocks to attract their males.
Thus, the correct answer is - intrasexual selection.
they cannot happen at the same time
Answer:
0.325 microliters
Explanation:
1 microgram = 1000 nanograms
DNA sample concentration= 1000 X 0.6 = 600 nanograms / microliters
We need a total of 50 microliter reactions, and the concentration should be 3.9 nanograms per microliter.
So, we need total 50 X 3.9 = 195 nanograms in 50 microliters.
Therefore, it required 195 / 600 = 0.325 microliters of DNA sample to be transferred.
