The correct answer is option b. higher levels of hemoglobin.
The partial pressure of the oxygen decrease as the height from the sea level is increased. Due to the decrease in the partial pressure, the amount of the oxygen delivered by the hemoglobin to cell decrease. So, in order to cope up the condition, the amount of the hemoglobin in the blood is increased. the increased amount of the hemoglobin delivers more oxygen than the normal amount of hemoglobin can do, so, it help in survival at low oxygen levels.
1: In deep parts of the ocean fish have been without light for so long they evolve so they can no longer use their eyes.
2: plants underwater evolved to use chemosynthesis to survive.
This app still posts the answers so just quote me. Might I recommend using easybib. Also if you found this helpful make my answer the brainliest.

An organism that has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
It needs 5 electrons. I would start by looking at a periodic table. The numbers on top are group numbers. Below each number is roman symbols like (lA, llA, IIIB, etc.). Phosphorus is in group 15. Under fifteen it has the Roman numeral of 5 (VA). There is a pattern in the periodic table. Each Roman numeral stands for how many valence electrons it has. Valence electrons are the outermost electrons of an atom.
Genetically altered meats have been created to have a higher and faster production rate, allowing for more profits to be made by companies, but at the same time allowing more product to reach the consumer, so more Americans can consume meat. This ability to produce more and more quickly is beneficial to growing numbers of people on the planet, as well as for export consumption. Yet, with a higher number of animals comes also comes with more pollution, water usage, as well as the untested and unverified quality of the meat after it has been grown, whether or not it truly is safe for human consumption.
