- One of these threats is the <em>"over-collection of cacti." </em>Due to its versatile use, the cactus is often sold as an ornamental plant.
- Another threat is the number of pests, such as <u>snails</u> and<u> slugs</u>, that attacks it yearly. It is a delicious food for<em> mealy bugs, red spider mites, gnats, flies, etc.</em>
- People often misunderstand the <u>cactus' water level need</u>s. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.
Muscle is the part of the body that is attached to the bones and are responsible mostly for body's locomotion. There are three types of which: (1) skeletal, (2) cardiac, (3) smooth.
This part of the body is compact and thus has a greater density because it occupies larger mass for a given volume.
density = mass / volume
Because it has great density then, the mass is also large. Thus, this accounts for a large portion of the body mass.

Answer:
Answer:
First let's add the missing piece of information
1. Protection
2. Electrolyte balance
3. Movement
4. Support
The answers
A. 3
B. 4
C. 1
D. 2
Explanation:
A. Muscles exert force against bones -3. Movement
Muscles puts a force on bones during contraction to cause body movement and lifting of objects.
B. The body's mass is suspended from bones and rest upon bones -4. Support
This provides support.
C. The lungs are surrounded by the ribs -1. Protection
The lungs are protected by the rib cage (12 sets of ribs) connected to the spine and around the lungs for protection.
D. Calcium is released from bones to restore the calcium levels in body fluids -2. Electrolyte balance
The bones is rich in calcium. It is deposited at high blood levels and released at low blood levels as it is controlled by PTH, vitamin D, and calcitonin.
