What percentage of a radioactive species would be found as daughter material after five half-lives?
Usually, 50%. That's what half-life means: the time required for 50% of the original radioisotope to undergo radioactive decay (or, alternatively, the time required for there to be a 50% chance that any given atom will have decayed). To be more specific: half of the original radioactive substance will have transformed into something else (it may still BE there, so in some sense it's "remaining", but it will be a different element or isotope). The reason for the "usually" is that it's a random process and for small numbers of atoms, the actual results may vary quite a bit from the statistically expected results. In particular, if there's only one atom, the amount remaining after one half-life period will be either 0% or 100% (50/50 chance of each).
Does binary fission produce excess of energy or creates new species?
Binary fission does not produce an excess of energy, it simply divides a single organism into two identical daughter cells. Additionally, binary fission does not create new species, as the process typically occurs within a single species reproducing asexually.
What are the two factors that determine a materials density of wood?
The two main factors that determine the density of wood are the species of the tree and the moisture content of the wood. Different tree species have varying densities due to their cellular structure and growth patterns. The amount of moisture present in the wood affects its weight and density, with denser wood typically having lower moisture content.
How is radioactive dating important for providing evidence for evolution?
It tells you how old fossils are
What causes a change in species?
The simplest method would be geographic separation of the species, allopactric speciation. The local population of this species is split asunder by some geographic barrier; perhaps a large number of the species, about half, cross a river and take up new territory there. Then the similar population gene pools start to draw apart as different mutations to the DNA and different selection pressures in the new environment shape the across the river species into a new species over time. Long enough and the two split species can not longer, or do not want to, interbreed. This is how bonobos became a new species from common chimpanzees.

How do you calculate percentage of species cover from quadrats?
To calculate the percentage of species cover from quadrats, first identify the total area of the quadrat. Then, for each species, measure the area covered by that species within the quadrat. The percentage cover for each species is calculated by dividing the area covered by that species by the total area of the quadrat, and then multiplying by 100. This process can be repeated for multiple quadrats to obtain an average percentage cover for each species across the study area.
