Answer: Option B
Pigs wallow in the mud to cool themselves down.
Explanation: Pigs' skin contains lots of fats, and fats serves as thermal insulator during cold (low temperatures); unfortunately, this feature turns becomes a disadvantage during heat (high temperatures). Hence, pigs frequently wallows in the mud (or any nearby cool water place) - to reduce their body temperature.
Hello There!
I remember taking this test on FLVS. I believe the answer is
A: Eukaryotic cells have multiple membranes.
Hope I helped :D
The percentage of hemoglobin that will be saturated when the PO2 is 20 mmHg is 20%.
<h3>Why is it beneficial for the hemoglobin near these tissues to NOT pick up oxygen?</h3>
It is recommended that the tissues do not absorb oxygen at this point because the affinity of hemoglobin for oxygen will be low since the medium will be acid due to the amount of hydrogen ions and carbon dioxide, situation that occurs in tissues where oxygen is metabolized quickly. Therefore, then there will be no absorption of oxygen from these tissues, but rather it will occur in oxygenated tissues such as the lungs. This is an effect called the 'Bohr effect' and allows oxygen to be released where it is most needed.
And the percentage of oxygen saturation will be 20% according to the hemoglobin saturation curve.

Answer:
Convergent evolution
Explanation:
Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.
