The data supports the fourth choice, that increasing air temperature and CO2 levels correlate with a decrease in dust concentration.
The first choice is unlikely to reflect dust concentration, and is more likely to be for air temperature. The second choice is false, because the dust concentration is more of a decreasing trend. The third choice is not true, as the spikes in air temperature and atmospheric CO2 concentrations seem to occur simultaneously, implying a positive correlation.
We see rainbows when the son is behind us and some type of water or rain is in front of us. When the sun light hits a raindrop it's refracted and is changed in direction.
(and we see them with our eyes mannnn or womannnn)
Answer:
In eukaryotic cells you find core and proximal promoters.
Promotors are specific DNA sequences where transcription factors (proteins) and RNA polymerase binds to initiate transcription. Promotors are located upstream the coding sequence
Core promoters are where RNA polymersae binds and proximal promoters are where transcription factors bind.
Enhancer elements are DNA sequences where transcription factors (proteins) bind to increase the rate of expresion of an specific gene. Enhancers can be located either upstream, downstream or thousands of nucleotids away from the of the coding region.
Explanation:
Promoters and enhancer are key elements for controling gene regulation. Transcription begins when chromatin rearranges from a condensed state to a accesible state, this allow to transcrition factors and RNA polymerase to bind specif DNA sequences (promotors). Proteins bind to enhancers , this complex develops a DNA loop, so that the protein that is bound to the enhancer interacts with the RNA polymersase. When this interaction is made, the activity of the RNA polymerase is increased.
Answer: Four pulmonary veins.
Explanation: Oxygen and nutrient rich blood will flow from the lungs back into this part called the left atrium (Or as some will call it, the left upper chamber in the heart). From there, it goes through four pulmonary veins.
Hope I could help! :)
This condition is known as a super oxide in which mutated enzyme extremely functional because it helps in production of cells .
when unstable molecules that contains oxygen and that easily react with other molecules in the cells. a build up of reactive oxygen species and cells causes damage of DNA ,RNA & protein ,which cause cell death.
super oxide refers various toxic oxygen containing free radicals such as monovalant anion O2 (negative) or that compound containing potassium super oxide KO2. reactive oxygen can cause damage to the basic building block of the cell. DNA damage can occur in the form of double stranded breaks as a result of reactive oxygen induced conversion of guanine to 8-oxo guanine.
