In 2001, a small population of mice in Colorado had 150 births, 110 deaths, 12 immigrants to the population, and 2 emigrants from the population. In 2002, Colorado experienced a severe drought. In this year, the birthrate for the population remained the same (150), but there
were 140 deaths, 2 immigrants to the population, and 12 emigrants from the population. Keeping in mind the equation for growth rate (r= [B
+ 1 - [D+]), explain what the population curve would look like for this population during the period from 2001 to 2002.

It would be a U-shaped curve because the population dropped and rebounded during these years.

It would be flat because the population experienced neither growth nor decline during these years.

It would show an increase in the population in 2001 and a flat line in 2002.

It would show an increase in the population in 2001 and a decrease in the population in 2002

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
