Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Answer: The estimated population is 1250 mice
Explanation: The method use was marked and recapture, in which individuals are marked in the first capture and after some time biologist trap a new group of individuals that can be or not marked
Whit this data is possible to estimate the size of a population applying the Peterson method but is important to make some considerations such as:
1. All indivuals have the same probability to be capture
2, The population remain constant in terms of birth and death rate.
Taking this into account, the formula that allows to determine the size of the population is:
N=CM / R
where N is the size of the population, C is number of indivuals trapped in recapture, M is number of individuals marked in the first capture and R is the number of marked animals trapped in recapture
In this case:
N = 250 * 200 / 40 = 1250
It would have to be the third answer, "a strong thunderstorm destroys many of the nests of a bird population."
Heritability is a measure that is used to estimate the variation of phenotypic traits (observable traits) in a given population due to the variation or changes in the genetic make up (genotype) among certain individuals. some of these traits includes color blindness, tongue rolling and curly hair among others. However, some traits such as nearsightedness are caused or influenced by the changes in the environment and therefore Heritability is not a factor to consider when dealing with such traits.
