Answer:
The chemical basis of Chargaff"s rule is the bonding properties of the DNA bases.
Explanation:
According to the Chargaff"s rule in a DNA molecule the total number of purine bases are equal with the total number of pyrimidine bases that means
Adenine +Guanine=Thymine +Cytosine
In simple words the rule is based on the 1:1 ratio of both purine and pyrimidine bases.
Answer is: Petrochemical production
Scavengers play an important role in the network of food. They keep the world clean from the remains of dead animals, or carrion. Scavengers break down this raw material and recycle it as nutrients into the environment. Vultures consume only the corpses of deceased animals.
The order is calcification of matrix >> cells differentiate into osteoblasts >> formation of the primary ossification >> osteoclasts break down the spongy bone >> formation of the secondary ossification (5,3,1,2,4). It is a fundamental process.
<h3>What are osteoblasts?</h3>
Osteoblasts are cells of the bones, which act to generate bone matrix and modulate the process of mineralization of the skeleton.
Endochondral ossification refers to the mechanism through which the cartilaginous bones generate longitudinal growth.
This mechanism (endochondral ossification) is fundamental during fetal/embryo development.
