Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.
Answer:
Warm temperatures and more frequent dry periods have stressed frog species such as the coqui making them more vulnerable to a lethal fungal infection thus reducing their populations.
Explanation:
Rise in temperature, flooding as well as drought affect biodiversity. As climate changes, there is usually an alteration of temperature as well as weather patterns, the impact is felt by
plant and animal life. According to
Scientists, there is an expectation that
number and range of species, which are regarded as biodiversity will experience declination with greatly increase in temperatures
it will be bumpy , ugly, and dirty
