The option which is not a characteristic of chordates is chloroplasts in their cells.
Chordates do have a dorsal supporting rod (vertebrates are types of chordates - they have a spine), a dorsal hollow nerve cord (within the spine), and pharyngeal pouches. However, they do not have chloroplasts, because that is a characteristic of photoautothropic eukaryotes, which chordates certainly are not.
<h2>Answer and Explanation</h2>
DNA is called deoxyribonucleic acid. DNA is different in all plants and animals but according to the chemical structure, it is the same as double helix strand that is separated from each other. In a person body, all the DNA are the same but they are different if the cells, tissues, and organs are different. There are some mammals have slightly similar DNA that is humans have 99.6% same DNA as the chimpanzees.
Answer
Light intensity increases also, but it gets to a point that the temperature increases and denature the enzymes involved so a plateau results.
Answer:
The rate of reaction depends on the rate determining step of a nonelementary reaction
Explanation:
A non elementary reaction is a reaction that proceeds in a sequence of steps. One of the steps is usually the slowest step in the reaction sequence. This slowest step is called the rate determining step. In an SN1 reaction, the rate determining step is the formation of the carbocation, the concentration of the carbocation affects the rate of reaction because it is involved in the rate determining step. The attack of the nucleophile is a fast step and does not affect the rate of reaction.
