Answer:
C.
Explanation:
Every DNA nucleotide pair will consist of one pyrimidine and one purine. Due to the chemical structures of the different bases, adenine (A) will always bind with thymine (T) and guanine (G) will bind with cytosine (C). The same is true for RNA except that A always pairs with a close relative of thymine, uracil (U).
Answer:
c. the formation of bone from within fibrous membranes
Explanation:
On the basis of formation ossification process is divided into two types:
1) Endochondral ossification : The process by which bone is formed from haline cartilage.
2) Intramembranous ossification : The process by which bone is formed by replacing a fibrous membrane and not from cartilage. This type of ossification occurs as follows :
- An ossification center appears in the fibrous connective tissue membrane.
- Bone matrix is secreted within fibrous membrane
- Woven bone and periosteum forms.
- Bone collar of compact bone forms and red marrow appears.
Hence option c. the formation of bone from within fibrous membranes is the right option
Answer:
Option B
Explanation:
An economics footprint can be described as a measure of biological productivity.
Ecological footprints show a comparison of the rapidness of our resources consumption and waste generation to the rapidness of natural absorbing these wastes and also including our carbon emission.
Thus, one of the characteristics of ecological footprints is a measure of our biological productivity.
