In which, normally, a person could still identify it even if the person is blind folded with the use of the left hand.
The cell would need more energy, so more mitochondria= more energy<span />
The normal osmolality of intracellular and extracellular fluid is 300 mosm, which makes them in osmotic<span> equilibrium. </span>
<span>This condition is better described as isosmotic. Water moves from high salt concentration to low salt concentration due to osmosis. The osmotic pressure of the extracellular fluid equals the osmotic pressure of the intracellular fluid (300 mosm), therefore no fluid movement across the plasma membrane.</span>
The advantages of asexual reproduction are that all favorable genetics are passed on to offspring and the favorable genetics will remain in the gene pool. The disadvantage is that the unfavorable genes / mutations will be passed on. The advantages of sexual reproduction are that the mutations can be diluted if the individual mates with another individual who lacks the mutation and if a virus or bacteria is killing off a species not all of the species will die because there is diversity in our genetics. The disadvantages are that mutations may be passed on if two individuals share that gene, favorable genes could be broken down, and it's ultimately less efficient in passing on genes.
