Answer:
Bones consist of living cells embedded in a mineralized organic matrix. This matrix consists of organic components, mainly type I collagen – "organic" referring to materials produced as a result of the human body – and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.
Explanation:
Answer: A.
Explanation: Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.
Oil the answer is c ur welcome sorry if late :)
Answer:
C. Uncompensated respiratory alkalosis
Explanation:
When the partial pressure of CO2 in systemic arteries falls below 35 mmHg, the condition is called respiratory alkalosis. Since pCO2 levels are below 35 mmHg (25 mmHg given), Kelsey is suffering from respiratory alkalosis. Alkalosis is also confirmed by higher pH levels (pH = 7.51).
The ratio of CO2 and HCO3 is around 1:1 (pCO2= 25 mmHg : HCO3= 22 mmEq/L) and confirms the "Uncompensated respiratory alkalosis". The compensated respiratory alkalosis reduces the HCO3 levels far below and exhibits the CO2: HCO3 ratio in the range of 10:2 to 10:4.
