Answer:
a, b, c are correct
Explanation:
Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.
Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.
Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.
There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.
Therefore, the correct options are (a), (b), and (c).
D because if the species was to be removed from an ecosystem, everything that needed that species as food, or the species ould have to adapt to the foods available in the new ecosystem they live in. Hope I helped, and let me know if you are still not 100% sure about the answer, and I'll try to clarify what I said.
Answer:
True
Explanation:
Let the allele for green color of pods be G
and the allele for yellow color of pods be g
Phenotype of true breeding parent with green colored seeds is GG
Phenotype of true breeding parent with yellow colored seeds is gg
In F1 cross
GG mates with gg
Genotype of offspring - Gg
Phenotype of offspring - Green seed
Since the offspring has both the allele for green and yellow seeds color but yet only green is expressed. This indicate that green allele dominated the expression of yellow allele thus, it can be concluded that green seed pods were dominant over yellow seed pods.
4. A
srry thats the only thing i can answer
Chlorophyll is a green pigment found in plants. Plants use chlorophyll and light to make food.
