Answer:
Three primary components of axial skeleton are skull, vertebral column and ribs.
Explanation:
Axial skeleton forms the central axis f the body. Three primary component of axial skeleton are:
Skull: Skull protects the brain and supports the face structure. Twenty two bones are present in the skull. Two main categories of skull bone are cranial bone and facial bone.
Vertebral column: Vertebral columns support and protects the spinal cord. The vertebral column serves as the attachment site for the muscles and neck.
Ribs cage: Ribs cage is also known as thoracic cage and includes the structure of sternum, ribs, coastal cartilage and thoracic cartilage. Ribs consists of twelve bones.
The correct answer is D. Without capsids, viruses could not replicate
Explanation:
A viral infection is caused as a virus enters the body and this replicates inside it by using the host's cells. This is possible through the capsid which is an external layer in the virus that provides protection to it and helps the virus replicate because the capsid is essential for the virus to attach and penetrate the host's cells to replicate. According to this, if a drug damages the capsids the virus could not replicate and this should or reduce the infection caused by the virus. Thus, a drug that damages capsids helps treat a viral infection because "without capsids, viruses could not replicate".
Endocytosis is the process by which Bulky Molecules enter the cell.
Explanation:
- Endocytosis is the process by which eukaryotic cells take up large molecules into their cytoplasm.
- The large molecules that cannot enter the cell through protein channels of the plasma membrane are carried into the cell in membrane bound vessicles.
- The vessicles are formed by progressive invagination of the cell membrane and then pinching off after the molecule is trapped.
- Endocytosis has been classified as phagocytosis (cell eating) and pinnocytosis(cell drinking).
C. Maintaining the chromosome number during sexual reproduction. I believe this is the answer
Answer:According to Thomson€™s model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere. Thus, by counterbalancing each other€™s effect, they make an atom neutral.
