Answer:
uhhhhhbh legs 0_0 and head
Answer and Explanation:
We need to create a nucleotide sequence, but first what are DNA nucleotides? They are the monomers of the entire nucleic acid strand of DNA.
DNA nucleotides have 4 bases: adenine (A), thymine (T), guanine (G), and cytosine (C). When pairing bases, A and T always go together and G and C always go together. (An interesting trick to remember this is Apple in the Tree and Car in the Garage.)
To create our own, we can draw up any combination of A's, T's, C's, and G's. I'm just going to arbitrarily write the following:
A A G C T T C G A T C G A C C
We need to pair these up by replicating it (remember A with T and G with C). The new strand will become:
T T C G A A G C T A G C T G G
Finally, we need to transcribe this back into the original format because replication is creating the same copy of something:
A A G C T T C G A T C G A C C
Answer:
Decrease in water/oxygen levels of the aquatic environment
Explanation:
<u>The environmental pressure that would cause primitive fish to adopt the genetic capacity to live on land would be a decrease in water levels of the aquatic environment.</u>
A constant decrease in water level that keeps exposing the fish to dry land will enable natural selection to start selecting for traits that will enable them to survive on land, especially, the development of lungs in the place of gills, the capacity to walk instead of swimming, and the capacity to avoid desiccation.
<em>A decrease in water level will mean a decrease in the amount of oxygen available for gill's respiration. Respiration is an important process for any organism to stay alive. </em>
<em>A decrease in water level also means an exposure to sun. The heat from the sun could cause death by desiccation.</em>
<em>A decrease in water level means that movement (through swimming) will be limited. Movement is necessary for feeding and other biological activities.</em>
The right option is; d. 366 people/mi^2
Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.
From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.
Population Density = Number of People / Land Area.
Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.
Therefore, the population density of China is 366 people per square mile.
genes that are linked together combine to form traits
