Answer:
Reptiles and amphibians share many traits which shows that they shared a common ancestor in the past. Some of the traits that are similar in reptilia and amphibia are:
1. Both are ectoderms: Reptiles and amphibians are cold-blooded animals and they can not regulate their body temperature on their own so they take heat from surrounding to warm their body and become active.
2. Both have four legs: Both reptile and amphibians have four legs for locomotion except some animals their group.
3. Both are vertebrates: Reptiles and amphibians have vertebral column, therefore, they both come under vertebrates.
Answer:
A. True
Explanation:
A space between the two bones of the synovial joint is called the joint cavity. It allows the synovial joints to move freely. The layer of hyaline cartilage covers the bones of the synovial joints. This is called articular cartilage. It forms a slippery surface to cover the bones. Due to the presence of cartilage, the friction is reduced between bones of the joints during movement.
Synovial joints may also have accessory ligaments present outside or within the articular capsule of the joints. Nerve endings are present in the articular capsule and the related ligaments of these joints. Similarly, blood vessels enter the ligaments and articular capsule of these joints.
The action that should be recommended by Lloyd to his partner if the heating must continue is to move the test tube so that the opening is pointing away from all students. Thus, the correct option is C.
<h3>What are the precautions that should be taken while heating the solution?</h3>
Safety and security are the foremost things that you should be required to keep in mind when performing lab experiments. You should be well aware of all its parameters.
While heating the solution, always keep away your face away from the direct opening of the test tubes, wear goggles if required, etc.
Therefore, the action that should be recommended by Lloyd to his partner if the heating must continue is to move the test tube so that the opening is pointing away from all students. Thus, the correct option is C.
