Answer:
The answer is - Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.
Explanation:
The options are:
A. Bacterial and eukaryotic cells are more closely related to each other than to archaeans, as evidenced by the fact that bacteria and eukaryotes do not inhabit the most extreme environments.
B. Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.
C. Bacteria and archaeans are more closely related to each other than to eukaryotes, as evidenced by their cell structures. Bacteria and archaeans are prokaryotic, while all eukaryotic cells contain mitochondria and other membrane-bound organelles.
D. The three domains of life are equally divergent from one another, so no two domains are more closely related to each other. This is supported by the evolutionary tree of life because three branches extend from one node millions of years ago.
The answer is - B. Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.
Archaea and bacteria are similar in terms of cellular organisation and size but are however similar to eukaryotes (eukarya) at the molecular level. Archaea and Eukaryotes both undergo DNA replication and protein synthesis the same mechanism. Both of them posses closely related genes and several metabolic pathways, including the enzymes in transcription and translation.
Hey there,
Q1 & Q2)
1) Heredity- Genes carry genetic information for cholesterol. So, it can be passed down from your parents.
2) Diet- Cholesterol depends on the food you eat. If you eat food with too much saturated fat, you get a high level of cholesterol.
3) Weight- If you are obese, you are more prone to get cholesterol. Thus, you need to lose weight
4) Exercise- Exercise regularly to maintain a perfect cholesterol level
5) Stress- If you are a student, take breaks in between study timings to keep you less stress or if you are an adult, go for walks and do something that you like the most to calm your brain down.
Q3) Cholesterol causes plague to grow in your hearts. This thick, hard plague will block the arteries and will cause heart attacks and strokes.
Q4) Pros- <span>Helps maintain healthy cholesterol levels, lowers risks of heart attacks and strokes
Cons- C</span><span>ould create too many HDL leaving not enough cholesterol for the body to be healthy.
Hope this helps :))

Answer: Gut microbiome degrade the ingested milk sugars through a biochemical pathway, producing ATP required for the energy needs of infant.
Explanation:
The human breast milk fed on by infants contains a high concentration of indigestible oligosaccharides which include lacto-N-tetraose and lacto-N-fucopentaose.
These milk sugars are utilized by microbes in the gut of infants, yielding lactate as the final product of metabolism and releasing several molecules of ATP as useful energy for use by the infant.
Thus, the presence of these gut microbes at birth, and the feeding of infant with breast milk is vital to fulfilling their energy needs
