That the oxygen levels in the test tube increased and carbon dioxide levels decreased because plants produce oxygen using carbon dioxide
Atomic number of an atom equals to the number of nucleus in the nucleus of the atom. Therefore, the answer is 74.
The proton of an element is never changed. No matter if it's an atom or ion. It's like an ID number for an element. It defines the type of element. Don't mix up atomic number with mass number though, mass number is the total sum of of the number of protons and neutrons in an atom.
Theres one more subatomic particle in an atom, that is electrons. But since they're too light, they won't be counted in mass. Also, the number of electrons in an atom equals to the number of proton, also the atomic number. If the number of electrons is different, it's no longer an atom, but an ion.
Hello fellow student! I'm here to help.
Well, both proteins and nucleus acids are both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways.
Answer:
D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs
Explanation:
Hog farms operate in three different categories:
Farrow-to-finish: This involves breeding sows to produce offspring. The offspring's are then fed until they are have reached the size for slaughter. The entire process takes throughout the hogs lifetime.
Feeder operations: This involves breeding sows and then selling their piglets to other farmers who will then raise them for till they are matured for slaughters. This process is just to raise young hogs.
Finisher operations: This involves buying piglets from other farmers and then raising them until they are matured for slaughter. This finisher operations raise older hogs
