Answer:
Freeze Fracture replication
Explanation:
<u>Freeze Fracture replication</u> is a technique that allows investigation of the microheterogeneity of a membrane so that one can see localized differences in different parts of the membrane.
Freeze fracture replication is a technique used with electron microscopy to splits frozen cell membranes apart for visualization of the membrane structure and the organization of proteins within the sea of phospholipids.
The four steps in making a freeze-fracture replication are
(i) rapid freezing,
(ii) fracturing,
(iii) replication and
(iv) replica cleaning.
Answer:
C = (7 + 8) i + (5 - 1) j adding vectors
C = 15 i + 4 j
theta = arctan (4 / 15) = 14.9 deg
Note that this is the same as adding x and y components
Speed=frequency*wavelength
Given
frequency=1200\ Hz
and
wavelength=0.300\ m
we get:
speed=1200\ Hz*0.300\ m=360\ m/s

Answer:
true
Explanation:
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
