Answer:
A biological membrane can be described as a membrane which encloses a cell. It separates a cell from the outer environment.
The main components of a biological membrane include proteins, lipids and carbohydrates. The carbohydrates either attach to lipids forming glycolipids or they attach to proteins forming glycoproteins.
The structure of a biological membrane constitutes of phosphate heads and tails which are made of fatty acids. The membrane contains a phospholipid bilayer.
Answer:
7.52 × 10⁻¹⁴ mi
Explanation:
Step 1: Given data
Bond length between two carbon atoms (l): 121 pm
Step 2: Convert "l" to meters
We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.
121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m
Step 3: Convert "l" to miles
We will use the conversion factor 1.00 mi = 1609.34 m.
1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi
I believe the first one, forgive me if I’m wrong, I’m not completely sure
Noble gas electron configurations are easier to write because they are shorter then full electron configurations. They Noble gas shortcut electron configuration is a way of summarizing the information about the electrons of an atom.
(this is what I used)
The mass number represents the summation of the number of protons and the number of neutrons in the nucleus of an atom.
We are given that the mass number is 64 and that the number of neutrons is 35. Therefore:
number of protons = 64 - 35 = 29 protons
In ground state, number of protons in an atom is equal to the number of electrons. Therefore,
number of electrons = 29 electron
Using the periodic table, we will find that the element that has 29 electrons in ground state is copper.
The nuclide symbol of copper is shown in the attached image.
