Answer:
Tetanospasmin toxin; Pulmonary embolism
Explanation:
Clostridium tetani produce a toxin called tetanospasmin. Tetanospasmin is the strong neurotoxin that blocks the motor neurons that control the muscles. Which results in stiffness of muscles.
Tetanus toxin ca cause blockage of lung artery (pulmonary embolism) and thus can cause death by:
- Stopping your breathing
- Pneumonia
- Cardiac arrest
Restriction enzyme cuts samples of DNA at restriction site; produces different lengths of DNA segments
Answer:
convergent evolution
Explanation:
If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.
Answer:
Recombinant DNA technology or genetic engineering.
Explanation:
Genetic engineering is a process that uses some techniques to cut and join DNA from biological species and introducing the novel DNA into another organism in order to form new combinations of traits or characters that can be inherited.
