Most of the joints in the appendicular skeleton are synovial joints.
So, the correct option is (c).
- A joint, sometimes referred to as an articulation, is where two or more bones come together. The names of two bones are included in each articulation.
- Immobile joints are ones that do not permit movement at the joint sites .These joints don't have a joint cavity; instead, dense fibrous connective tissue, typically collagen, holds the bones physically together.
- A synovial membrane-lined joint capsule that produces synovial fluid surrounds and protects the two of them.
- Specialized joints known as cartilaginous joints can be identified by their structural characteristics.
- In fibrous joints, white connective tissue fibres that travel from one articulating portion to the next separate the articulating parts.

Answer:
B. The native species population would decrease because the nonnative species would be competing for food sources.
Explanation:
This question is describing the effect of invasive species. Invasive species are foreign species i.e. not native to a habitat or area, introduced into the area with the ability to outcompete and negatively affect the native species of that area.
Invasive species compete with the native species for food, space, mate etc., and tend to outgrow them. Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.
Answer:
Explanation:
The resolving power of the microscope is dependent upon the objective lens. It can be measured by the ability of the lens to differentiate between the two lines or points on the specimen under observation. The more the resolving power the smaller will be the distance between the two lines or points that can be distinguished.
The following are the two ways that can be used to enhance the resolving power on the microscope:
Using a lens that has a higher aperture.
Decreasing the amount of light being entered into the microscope that means using light of less wavelength.
