This invention was a commercial failure. Edison resolved that in the future he would only invent things that he was certain the public would want. ... This gave Edison the money he needed to set up his first small laboratory and manufacturing facility in Newark, New Jersey in 1871.

Answer:
The lack of Mad1 protein can cause faster cell division.
Explanation:
The Mad1 protein is responsible for regulating the fixation of chromosomes in spindle microtubules, during cell division. With the presence of this protein, anaphase is prevented from starting while the spindle, where the chromosomes attach, is formed.
Without this protein, this check is not done and cell division occurs faster, which is one of the reasons why cell division can be accelerated.

Answer:
Sexual reproduction:
Pros: leads to greater genetic variation. 
Cons: requires more time and energy. 
Asexual reproduction: 
Pros: Does not require finding a mate. 
Cons: Produce less genetic variation. 
Explanation:
Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals. 
Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis. 
Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development. 
Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion. 
Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate. 
Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.
 
        
                    
             
        
        
        
Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
