Name the three types of population distribution, describe each, and explain the conditions that govern each.
tankabanditka [31]

Answer: Population distributions may be described as <em>random, uniform</em><em> or </em><em>clustered.</em>

Explanation:

In a specified region, a population comprises any  number of members of the same species. Populations are described by sizes- the number of individuals; densities-  individuals in a set space (per unit area); and distribution- the dispersal or non dispersal of individuals (spread out or clumped). Population distributions may be described in three ways:

  • Random: the distribution pattern is haphazard, with no regular spacing; individuals grow independently of each other without competing and resources are consistent. <em>E.g. dandelion seed dispersal by wind </em>

  • Uniform:  individuals are evenly spaced in a predictable pattern; there may be some interaction and ideally, spaces between them  are maximized in order to ensure access to limited nutrients and resources.<em> E.g.  human farming- cornfields, orchards; allelopathy in plants like purple sage, which secretes chemicals to prevent the growth of other plants nearby</em>

  • Clumped: there is less distance between neighboring organisms and these individuals cluster together. This pattern is most common in environments where resources are scarce, or the species is dependent on social interactions.<em> E.g. lions are highly social and hunt in prides in the wild</em>

Which statement describes a similarity between meiosis and mitosis
VLD [36.1K]

Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid. A diploid means containing the normal amount of chromosomes. This is the result of DNA replication and 1 cell division. ... Meiosis is used to produce gametes which are sperm and egg cells, the cells of sexual reproduction.

They are similar because crossing over happens in both.
