What dies survivor ship curve mean? What an easy way to remember what it means?
vredina [299]
Survivorship curve = so, first of all, it's a curve, as in a graph.

It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.

However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.

So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.

How many nucleotide bases differ between your sample (labeled as O. Kisutch) and the standard sequence for O. Kisutch? Sample la
OverLord2011 [107]

The right answer is 3 nucleotide bases.

5'-CGGCACCGCCCTAAGTCTCT-3'

5'-AGGCACCGCCCTAAGTCTAC-3'

It would be necessary first to align the two sequences side by side so as to be able to compare them, and they should also be in the same direction.

The nucleotides marked in bold are the nucleotides that differ between standard and O. Kisutch.

These nucleotide changes are necessarily due to substitution mutations that exchanged one nucleotide for another in the same location.

Which planet appears to be rotating on its side
katrin2010 [14]

Answer:

Uranus
