Options have not been provided for the question. They are as follows:
What is the correct order for these genes using a linkage map analysis?  
A. Z-X-Y-W
B. X-W-Z-Y
C. W-X-Y-Z
D. Y-W-Z-X
E. Z-X-W-Y
F. Y-X-W-Z
Between which two genes is crossing over most likely to occur?
A. B and D
B.X and Z
C. X and W
D. X and Y
E. W and Z
F. Y and W
G.Y and Z
Answer:
Correct order for these genes using a linkage map analysis: E. Z-X-W-Y
Two genes between which the crossover is most likely to occur: G.Y and Z
Explanation:
According to linkage concept, recombination frequency between two genes = distance between two genes in cM
Here, smallest distance is between X and W ( 7cM ) so they are present next to each other. Distance between X and Y is 17cM and between W and Y is 10cM so W is present between X and Y. Distance between X and Z is 13 cM. Since on one side of X, W and Y are already present Z lies on the other side. So, the final gene order comes out to be, Z-X-W-Y.
According to the gene order, Y and Z genes are farthest from each other. Chances of crossover or recombination increases with increasing distance between genes. So, Y and Z have the highest probability to show crossing over.
 
        
             
        
        
        
Since the radiation has no mass .It is Gamma radiation.
Step by Step Explanation:
Characteristics of Gamma radiation are as follows:
- Gamma radiations are chargeless.
- It is Electromagnetic wave having a very short wavelength.
- It is not effected by the electric or magnetic field.
- It has velocity equal to light in vaccum .
- It has a very high intensity and can penetrate long distances.
- It has a very low ionizing power. i.e. it does not ionize the medium in whic it travels.
Gamma radiation has proved itself to be very useful in radioactive treatment of cancer due to its high penetrating power.  
 
        
             
        
        
        
Fat and oxygen are the substances that moves
passively from the lipid part of the membrane, other substances which moves
from the membrane are steroids and oxygen.
<span>The membrane which separates the cell from the
outside environment is cell membrane and phospholipid is the major lipid or
primary type of lipid which is used in the cell membrane.</span>
 
        
             
        
        
        
 <u>Sensory</u> memory.
Explanation:
Sensory memory is the type of memory that stores information for a very brief period of time it is even shorter than the time period of  the short term memory.
Sensory memory helps the  brain to hold the effects  of a sensory stimulus for sometime  even after the stimulus has ceased. This helps in continuous perception and processing of data in the brain.
The  expression of continuous reading, writing and speaking are due to the existence of sensory memory.
If sensory memory does not function properly then, the synchronization of words and their understanding would have been impossible.
