Answer:
1. axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments
Explanation:
The axial skeleton consists of the bones of the head and trunk of a vertebrate including skull, and rib cage.
Bone marrow produces red blood cells, which carry oxygen in the blood.
Osteoblasts can become osteocytes, which are the third type of bone cells.
Osteoporosis is a bone resorption disease in which bones rapidly deconstruct faster than new bone tissue grows, and decreases the mechanical strength of bones.
Ligaments connects one bone to other at joint such as medial collateral ligament (MCL) and anterior cruciate ligament (ACL) that joins knee.
Hence, the correct answer for the question is as follows:
1.axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments

Answer:
A possible explanation for this color change could be the acid present in the Snail slime has brought the color change.
Explanation:
- Snails are Gastropod molluscs.
- They secrete a mucus like watery slime to adhere to the surface .
- Snails also use their slime as a defense.
- Chemical analysis of snail slime suggested that it contains hyaluronic acid and glycolic acid along with other components.
- Thus we can state that snail slime is acidic in nature.
- In the given question it is stated that the blue solution turns yellow on adding a weak acid.
- So when the color of water changed from blue to yellow after 30 minutes, we can assume that the colour change was caused due to the slime secreted by Aquatic snail that was introduced into the tube.

Plasmolysis is the reason. The reason that the Elodea cell prevents from collapsing completely is that the Plasmolysis is the main reason because it always has water to keep it full. The answer in this question is Plasmolysis is the reason because it always has water to keep it full.
Answer:
Cheek cells lack a rigid cell wall and due to this their shape is not as well defined as a plant cell.
Explanation:
- Cell wall is the outermost structure in plant and bacterial cells.
- The plant cell wall is made up of cellulose and provide rigidity and shape to the cell.
- In animal cell, the cell wall is absent and the outermost part of the cell is the cell memrane.
- This is the reason that most animal cell lack rigidity and shape.
