Im thinking its D. bcuz all three A. B. C. are true
Answer:
A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
——————-
P | PP | Pp |
——————-
p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.
Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Answer:
Alcohol and carbon dioxide
Explanation:
Fermentation is a process carried out mostly by two organisms namely: bacteria and yeast. The bacteria converts sugar molecules to lactic acid, hence, it is called LACTIC ACID FERMENTATION. However, on the other hand, the YEAST converts sugar molecules to ALCOHOL (ETHANOL) and CO2.
Yeast is an organism capable of undergoing both aerobic and anaerobic (fermentation) respiration depending on the availability of oxygen. This fermentation process enables it produce fermented foods e.g beer, yoghurt by producing ALCOHOL as a product.
