Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments.The Earth's magnetic field is somewhat caused by the composition of the earth's core which is rich in iron minerals. There is a solid inner core that is made of iron which makes up to 2/3 of the moon's size. The charged metal of the iron produces electric currents, consequently resulting to Earth's magnetic field.
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:
1. Evolution can be defined as the gradual development of an organism creating diversity.
2. A common misconception is that Homosapiens are descendants of Apes.
3. analogous structures are features of different species that are similar in function, but not necessarily in structure; such as bird wings and insect wings. homologous structures, however, is an organ or bone with similar underlying anatomical features found in different animals; such as the arms of primates.
4. vestigial structures are structures that have no apparent function and appear to be residual parts from a past ancestor, such as wings of flightless birds.
5. Embryology supports the theory that organisms have a common ancestor in accordance to the theory of evolution.

I am not sure if this question means the adjective form or the adjacent form? However, a Schwann cell is a type of glial cell and its main function is to support neurons. Adjacent to the Schwann cell are nodes of Ranvier which are gaps in the myelinated axons, and are believed to assist in potential generation among other things.
