Answer:
Fermentation allows production of energy without oxygen. This is helpful for conserving oxygen.
Explanation:
A common practice is to insert a gene of bioluminescence into the bacteria's plasmid so that identifying them becomes easy. However, if this method was not employed, then we can put the bacteria into growth cultures and give them conditions to promote the production of the protein coded by the inserted gene. The bacteria that produce the protein contain the engineered plasmids and those that do not contain the original plasmids.
Answer: 2 They involve a different number of parents.
3 Only one process involves sperm and eggs.
5 Only one process involves cell division.
Explanation:
The sexual and asexual reproduction are the two modes of reproduction through which the organisms produce offspring and lead their generations. The asexual reproduction takes place in simple organisms whereas the sexual reproduction takes place in complex organisms.
The following are the differences between asexual and sexual reproduction:
2 They involve a different number of parents.: In asexual reproduction only single parent is involved which produces a large number of offspring whereas in sexual reproduction two parents are involved which produces limited number of offspring.
3 Only one process involves sperm and eggs.: In sexual reproduction the fusion of the male and female gametes is required for production of offspring.
5 Only one process involves cell division.: Asexual reproduction occurs through cell division that is a single parent cell get split into two daughter cells.
The DNA is identical in offspring produced by asexual reproduction but not similar in offspring produced by sexual reproduction as two parents are involved and segregation of chromosomes takes place during gamete formation.
Meiosis does not occur in asexual reproduction. This occurs in sexual reproduction during gamete formation.
Answer:
Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation and it allows for snails to have increased genetic variation.
Explanation:
The sexual reproduction allows genetic interchange which is very good for both the individuals and the species as a whole. In asexual reproduction, on the other hand, each offspring is genetically identical to every other. This allows for the ongoing accumulation and replication of harmful mutations and little room for adaptation to rapidly changing environments.
