"The mouth" is the correct answer
Answer:
A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway. This lower activation energy means that a larger fraction of collisions are successful at a given temperature, leading to an increased reaction rate.

<em>Cartilaginous joints</em> is not a functional classification for joints.
Answer: Option 2
Explanation:
The joints are classified based upon their <em>structure and function</em>. Based upon the composition as well as presence or absence of the cavity, the joints are <em>structurally</em> classified as:
- Fibrous joints
- Cartilaginous joints
- Synovial joints
On the other hand, based upon the functions performed by the joints, the <em>functional </em>classification of joints are as follows:
- Diarthrosis
- Amphiarthrosis
- Synarthrosis
Thus it is inferred that, cartilaginous joint is structural classification of joints, not functional.
Answer:
11/12 is greater than 2/3!
Earth and Venus have similar sizes. Earth's diameter is 12,756.2 km and Venus' 12,103.6 making Earth's 5% larger.
Their composition is also similar. They both have metal cores, silica rock and thin crust.
