Answer:
Some similarities between a sea slug and a spotted salamander:
1. They both reproduce in a water source. For sea slug oceans, while for Spotted salamander, mostly ponds.
2. They both lay eggs meaning they are oviparous.
Explanation:
The sea slug is an aquatic animal without a bony skeleton. Spotted salamander have a bony skeleton with a similar resemblance to that of a lizard in shape but are diffferent in color, they are amphibians
The first major difference between prokaryote and eukaryote gene expression is the location. Due to lack of compartments (nucleus) prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm (genetic material is located within the cytoplasm). So, transcription and translation in prokaryote occurs simultaneously. Gene expression in eukaryote occurs in both the nucleus (transcription) and cytoplasm (translation).
The steps of regulation of gene expression are also dissimilar, in prokaryotic cell, transcription is mostly the main point of regulation (eukaryote have transcription, post-transcription, translation, and post-translation regulation together with epigenetic regulation).
Answer:
A
Explanation:
The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution, people are prone to obesity by storing energy as fat, an ability to take advantage of rare periods of abundance and this is advantageous during times of food availability. individuals with greater adipose reserves would more likely survive famine. This tendency to store fat could lead to obesity.
FTO is an enzyme that is encoded in humans by FTO gene located on chromosome 16. Increase in this enzyme is associated with the regulation of energy intake but not feeding reward. Also, the set point theory indicates that bodies are meant to stay within a narrow weight range but it is susceptible to chnage overtime.
