Asthma occurs when the airways to the lungs become too narrow. How would the circulatory and respiratory systems be affected by asthma?
Choose 2 answers:
A
The circulatory system would have a significantly reduced supply of oxygen in the blood,
causing oxygen delivery to cells to be reduced.
B
The circulatory system would have a significantly reduced supply of oxygen in the blood,
causing oxygen delivery to cells to increase.
С
The respiratory system would have difficulty delivering enough oxygen to the lungs because
the airways are not wide enough.
The respiratory stem would be over-delivering oxygen to the lungs because the person
would be breathing too rapidly.

Choose a mutation from those in model 2 that would be neutral for a cell. explain your reasoning by relating the mutation to the cellular respiration process.

Step 1 review the imaginary strand of dna below. note the complementary base pairs. a g c a a t c c g t c t t g g t c g t t a g g c a g a a c c step 2 to begin replicating this strand of dna, draw the two sides of the strand separating. step 3 now, draw the free-floating bases linking up with the separate sides. remember to follow the rules of complementary base pairing. step 4 draw the two resulting dna strands.

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
