Answer: Botulinum toxin
Toxins are non-living
biological and chemical agents produced by living microorganisms from animals
and plants that can cause harm to humans, plants and animals. An example of
toxin is botulinum toxin produced by the bacterium Clostridium, which is a
neurotoxic protein that prevents the release of the neurotransmitter
acetylcholine from axon endings at the neuromuscular junction and causes
flaccid paralysis.
Moreover, toxin are more
closely related to chemical warfare agents that can only affect those who are
exposed to the agent and that they are not considered as transmissible disease.
Answer:
disease, toxins, and pathogens
Explanation:
im pretty sure that that is the kinds of stimuli
Answer:
The STR fragments will have different size for different animals.
Explanation:
- STR means Short Tandem Repeats.
- STR forms the genome's microsatellite region.
- STR or microsatellite is that region of the genome where, about two to seven base pairs of the DNA (for example, ATGATGATGATG), are repeated for multiple time. Such sequences can have few hundred repeats.
- While replicating these micro-satellite regions, the accuracy of the DNA polymerase in proof-reading the sequence of the newly synthesised strand, decreases, due to the multiple repeats.
- As a result of this, the DNA polymerase either adds more or adds less of such repeated sequences as compared to the parental DNA sequence. This results in generation of polymorphism (different microsatellite size in different individuals) in the repeat regions.
- Due to difference in size of the STR in different individuals, the size of the fragment amplified through PCR will vary for different elephants.
Answer: CHEMICAL ENERGY
Explanation: All organisms need glucose, or a source of CHEMICAL ENERGY, to carry out basic life functions.
