Answer:
Answer is whole-gene or whole-genome.
Explanation:
Genetic variation explains that, no matter how related or identical some organisms might be, there is a or some characters that make them different from one another. These difference is referred to as variation.
Furthermore, whole-gene means the coding and non-coding regions of the DNA>
There are some activities or occurrences that cause genetic variation, these are gene flow, mutation and sexual reproduction.
Examples of genetic variation are color of the eyes, modification of leaf and blood type among others.
No, studying the effects of sunlight on the color of paper would be an experiment in qualitative data. Quantitative data is based on numbers, a change in appearance is qualitative data.
Answer:
(a) Allow movement in only one plane/direction (that is extension or flexion)
(b) The skeletal system also produces blood cells in their bone marrow
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.
