Global warming is a long-term rise in the average temperature of the Earth's climate system. And the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
 
        
             
        
        
        
Answer: Option D 
Explanation: 
Once the pathogen enters the body, it starts dividing and after a certain period of time the patients experience some sign and symptoms of illness.
The prodromal period occurs just after the incubation period. In this phase the pathogen keeps on dividing and the host begins to experience general symptoms and signs of illness.
This is a result of the activation of immune system of the body which results in the swelling, pain, soreness.
 
        
             
        
        
        
Answer:
 6.25%
Explanation:
Given that:
The trait of a female fruit fly that is heterozygous for red eyes = XRXr;   &
The trait of a white-eyed male is XrY_ ; 
since Y is dominant y; the male trait can either be XrYR or XrYr
So, let assume that it is XrYr 
Then; if each trait self crossed; we have:
XRXr = XX    Xr    XR    Rr
XrYr = XY    Xr     rY    rr
Thus, the punnet Square can be computed as:
                XX             Xr             XR           Rr
XY         XXXY       XXYr         XXYR        XRYr
Xr          XXXr         XXrr          XXRr        XRrr
rY          XrYX          XxYr         XrYR        RrYr
rr            XrXr          Xrrr           XrRr        Rrrr
∴
the percentage of offspring that would have white eyes XrY_ is:
1/16 = 0.0625
= 6.25%
 
        
             
        
        
        
By dividing the amount of work done by the time it takes to do it; by dividing energy used in a given period by time.
