Answer:
Asexual plant propagation methods produce new plants from vegetative parts of the original plant, such as the leaves, stems and roots. These methods are generally referred to as vegetative propagation.
<h3>e.g. rhizome, bulb, tuber etc</h3>

The DNA is splitting in two, thymine pairs with adenine, and guanine pairs with cytosine
The Haploid number is half (haploid cells are sex cells egg and sperm they have half as many chromosomes as the diploid cells which are normal cells ) of the chromosomes so that would be 12. To clarify that if a organism has 12 chromosomes and reproduce sexually it takes two

Answer:
Examples:
- Short-term adaptation: feedback inhibition
- Long-term adaptation: regulation of gene expression
Explanation:
Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
