One example would be the chemicals they use in the soil to make the plants grow faster and another example would be chemicals they use to kill pest so they wont eat the crops or you could say bioengineering has enhanced the crops
The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
Correct Answer: Ratio
Determining a person’s reaction time would involve measurement on a
ratio scale that is expressed in milliseconds. It is a point where none of the quality being measured
exists and its scale has an absolute zero. In ratio scale, it allows comparisons
such as being twice as high or one-half as much. Additionally, in the case of a
person’s reaction time, it can be state that a response of 25 milliseconds is
twice as fast as a response time of 50 milliseconds.
Answer:
There are 2 electrons on the first energy level, 8 electrons on the second level, 8 electrons on the third energy level, and 1 on the fourth energy level. Explain that after the third energy level has 8 electrons, the next electron goes into the fourth level.
