Answer:
Electrons
Explanation:
Atoms both have negative and positive particles
Protons are positive
Electrons are negative
Neutrons are neutral
Nuclei is where you find both neutrons and protons in an atom
Answer:
this may help
Explanation:
in primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Answer:
The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.

Answer: The amino acid sequence is Leu-Ser-Val
Explanation: To produce amino acids, the DNA has to "transform" itself into a RNA by a process called Transcription. In this process, part of the DNA is transcribed into a similar RNA. The RNA produced undergoes another process, called Translation. From it, the sequence is decoded to a specific polypetide, as shown in this case. In the Translation, each 3 bases corresnpond to 1 amino acid. Because of it, the sequence above has 3 amino acids.
The N-terminal and C-terminal relates to the part where the sequence start to be read and the end of the process. Normally, the sequence starts at the 5', which correspond to the N-terminal and finishes at the 3', which matches the C-terminal. So in this example, the DNA template read 5\'GACAGACAA 3\'.
Answer:

Explanation:
Hello,
In this case, we could considering this as a redox titration:

Thus, the balance turns out (by adding both hydrogen ions and water):

Thus, by stoichiometry, the grams of Fe+2 ions result:

Finally, the mass percent is:
