The answer is <span>restrictive disease.
</span>Restrictive disease it's when the total lung volume is too low. The normal value is 5 liters and 2 liters would be classified as restrictive disease.
It increased work of breathing and causes inadequate oxygenation.
Spirometry is not 100% accurate diagnosis because there is always residual lung volume that can't be measured but it's still very good to diagnose.
Answer:
Answer is C.
Explanation:
For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.
Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
Answer:
The membrane will move to the left in view of the applied pressure.
Explanation:
The scenario described can be perfectly illustrated through understanding the concept of osmosis.
Osmosis can be defined as the movement of particules or molecules in a solvent from a region of lower concentration to a region of higher concentration, through a semi permeable membrane.
To put differently, the movement of water molecules is from a region of lower osmotic pressure to a higher one. And for osmosis to be achieved and water molecules evenly distributed, pressure built must be slow and steady to a state of high or equilibrium.
This often results to movement of membrane to the left as a response to the osmosis phenomenon. Increasing the number of water molecules in the extra cellular fluid will thus accelerate this process, increase the pressure built up, and thus generate ripples from a lower area to a higher one. Osmosis is thus gradual and steady.
The crabs are salt water organisms, so they'll have a higher concentration gradient than the distilled water. In other words, they're hypertonic to the distilled water. This will cause them to take on water and expand; their cells bursting.
