Answer:
see if the strips repel each other when brought close together
Explanation:
Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance.
Since Ike knows that each strip of tape carries a negative charge, he could see if the strips repel each other when brought close together.
Answer:
D) molecules diffuse through transport proteins.
<u>Answer:</u>
Option (3)
The arms mostly contains old blue and blue-white stars
<u>Explanation:</u>
Spiral arms are the regions in stars extending from the middle of spiral galaxies and the barred spiral. Those long, thin areas look like a spiral and therefore give their name to spiral galaxies.
Spiral arms, though, include many young, blue stars, that render their arms so bright (due to the high mass density and the fast stellar forming rates).
The correct answer is: silent mutation
There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:
1. Substitution-only one base is changed
• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon
• Missense mutations-when one nucleotide is substituted and a different codon is formed
• Silent mutations-when a nucleotide is substituted and the same amino acid is produced
2. Insertion- extra base pairs are inserted
3. Deletion- section of DNA is deleted
Answer:
Explanation:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
