Answer:
A) Spore capsules
Explanation:
Ferns produce spore capsules contained in the sporangium (plural: sporangia), a structure localized on the undersides of the leaves. Moreover, the sporangia are borne in clusters known as sori (singular sorus). The spores are single reproductive cells that, when mature, are released from the sporangium to germinate on soil and produce new ferns. In a fern sporangium, the maximum number of spores is 64, although this number depends on the species.
Answer:
Each of her parents must have one recessive gene for blond hair color
Explanation:
- Blond is a recessive trait
- Since Silvia is blond this means she has both copies of the recessive gene for hair color
- Therefore, both her parents have a recessive gene for blond hair and passed it down to her.
- The parents don't have blond hair because their dominant gene for browns masks the recessive gene for blond.
You didn’t post the chart
Answer:
■Gene sequences would be used to make Probes for both the Southern and Northern blots.
■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium
■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism
■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present
■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one
■since all the genes present in the genome couldn't be identified, the northern would be important to work on
■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.
Answer:
They lack a nucleus, but they do have ribosomes.
Explanation:
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
