Answer:
What two features are first seen in the planarians? Planarians have bilateral symmetry, which is associated with the development of a head region, such as that seen in the flatworm. Another feature first seen in the flatworm is the possession of three cell layers: ectoderm, endoderm, and mesoderm (the middle layer).
Explanation:
Answer:
Autosomes
Explanation:
The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female. Females have two X chromosomes, while males have one X and one Y chromosome.
Hope this helps!
Oxygen. I got this answer because the process of Oxidation is when oxygen bonds with an element. Such as Iron Oxide, which is rust. So oxygen does, infact, have more of a role in chemical weathering.

The induced-fit model includes the change in the conformational site of the substrate and enzyme. It is done till the enzyme completely binds the substrate. This will then activates the enzyme to perform its work.
<h3>What is induced fit theory?</h3>
Induced fit theory or model suggest that the activation site of enzymes and the binding site of substrates undergo some conformational changes to fit into each other.
This binding results in activation of the enzyme and as the enzyme has a three-dimensional tertiary structure, this would help it to get fitted into the substrate.
Thus, with reference to the induced fit model tertiary structure of enzyme facilitates its function as a biological catalyst.
