Answer:
1. Conjugation
2. Diploid
3. External fertilization
4. Fertilization
5. Haploid
Explanation:
Conjugation is a cell-to-cell encounter between bacteria cells. The bacteria come close to each other and DNA is then transferred through a tube-;ike structure called pilius.
The difference between diploid and haploid is that diploid organisms have chromosomes that come in pairs. The chromosomes are paired up with another chromosome that is similar in shape and size and that is why they are called homologous pairs. Haploid on the other hand do not come in pairs. In human beings for example, the egg cell and sperm cell are haploid, only having one homologous chromosome. When they join together during fertlization, they form a diploid.
Fertilization is the union of gamete cells, male and female, which result in the formation of a zygote. There are two types of fertilization, internal and external. Internal fertilization occurs when the union of the sex cells (gametes) occur inside the organism. You would see this in humans, where fertilization occurs in the womb. External fertilization occurs when the union occurs outside the organism and a good example of this would be fish. The female expels it's eggs into the water and the male would release its own sex cells as well, and they would join in the water.
