Answer:
(x - 1)(x - 2)(x + 3)
Explanation:
f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).
After division -->
f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.
Find 2 numbers knowing sum (1) and product (-6). They are -2 and 3.
Therefor, f(x)=(x-1)(x-2)(x+3)
The atomic number of oxygen is 8
The atomic number of zinc is 30
The atomic number of Lithium is 3
The atomic mass of oxygen is 15.999, for zinc it is 65.39, and Lithium is 6.941
The number of protons for oxygen is 8, for zinc it is 30, and for Lithium is 3.
The number of neutrons for oxygen is 8, for zinc it is 35, and for lithium is 4. To find the number of neutrons you have to do atomic mass - atomic number.I rounded the answers to find the #of neutrons.
The number of electrons is always the same as the number or protons so the answer is for oxygen 8, zinc 30, and lithium 3.
I hope this helped you. If you can please make branliest :)
Answer: prokaryotic cells have no nucleus, no organelles and a small amount of DNA. Eukaryotic cells do have a nucleus, along with many organelles, and more DNA.
Explanation:
Answer: A) Atom, Molecule, Cell
Explanation: An atom is the smallest unit of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. And molecules join together to form cells.
1. Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
Pigments inside the photosystems absorb light energy. Energy is transferred to reaction center, where electron is boosted at higher level. Electron is then passed to an acceptor molecule, replaced with an electron from H2O. and O2 is released.
2. Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space
Electron releases energy because it goes from a higher to a lower energy level.
3. The concentration of hydrogen ions in the thylakoid space increase
Released energy of electrons drives pumping of hydrogen ions from the stroma into the thylakoid interior, building a proton gradient.
4. Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
The only way for hydrogen ions to move down the gradient is through ATP synthase.
5. ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
ATP synthase is an enzyme that use proton gradient to make ATP from ADP and Pi.
