Answer:
a. 1/2 b. The organism is an animal
Explanation:
a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?
Medullary index = diameter of medulla/diameter of hair.
Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,
Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2
b. Is this organism human or animal?
Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.
Only eukaryotes have a nucleus...all the other answers are true for both euks and proks...remember that only eukaryotes have internal membranes.
It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer. The statue of Leshan giant Buddha in Sichuan, China, is carved directly into the mountainside, and the <span>color and texture of the statue are constantly changing due to the pollutants from vehicles and industries nearby. The two main causes of the changes to the statue are RAINFALL AND CHEMICAL REACTION.</span>
Glycolysis evolved very early in ancestors that are common to all the domains of life.
This is because the site of glycolysis is cytoplasm which is present in both prokaryotes as well as eukaryotes.
As prokaryotes are the early ancestors of all domains of life therefore it is also considered that glycolysis is evolved very early.
