Given merely 40 butterflies were marked, assumed that there were multiple captures of both marked and unmarked butterflies, that the butterflies caught in traps were on the loose to be caught again. There are two mathematical solutions for this, both yielding the same answer which is 100.
• First, to each marked butterfly was taken twice (40 marked X2 = 80 captured) then of the unmarked butterflies the 120 captured must relate to 60 actual butterflies. In which 40 + 60 = 100.
• Secondly, by means of ratios in which 80/200 = 40/X. In this case X also = 100 that will result to the estimated size of the population of wilson park is 100.
It's true cause plants make oxygen that all animals breathe.
Answer:
Ball-and-stick models show the bonds between atoms, but not the relative sizes of atoms. Space-filling models show the relative sizes of atoms, but not the bonds between atoms.
The phenomenon of populations of organisms changing from generation to generation is known as biological evolution.
<h3>What is biological evolution?</h3>
Biological evolution is a scientific term that deals with the change in inherited traits through successive generations in an organism's population. For example, penguins have typical wings over swim-friendly flippers which were there for many generations. It is also called microevolution. Biological evolution is important because it helps us to understand why an organism is the way they are. Mutation, genetic drift, gene flow, and non-random mating are some of the causes of biological evolution. Heredity and Reproduction are the top conditions for biological evolution.

Answer:
It is used in the step of transformation, in order to make more plasmid DNA and consequently more gene product of interest
Explanation:
DNA cloning, as a method in molecular biology, is used for the multiplication of gene (or other piece of DNA). It usually includes steps of DNA insertion into plasmid (prokaryotic circular piece of DNA). That plasmid is than introduced into bacteria via process called transformation. Transformed bacteria can produce large amount of a product of a certain gene, because of their fast gene expression.
