If all cells in your body contain the same DNA why do they perform different functions. Pls help
Answers
Answer: These cells are different because they use the same set of genes differently. So even though each of our cells has the same genes, each cell can select which ones it wants to "turn on" and which ones it wants to keep "turned off". So when everything is working properly, each cell type only reads the genes it needs.
Explanation:
They are differentiated based on the genes that's why they perform different function.
it involves a switch from one pattern of gene expression to another. What are genes? Gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called.Many genes do not code for proteins.To know more about genes here

Describe an example of fermentation that occurs in beneficial bacterial cells within animals and explain why it is important.
Answers
Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce. Fermentation helps break down nutrients in food, making them easier to digest than their unfermented counterparts. For example, lactose — the natural sugar in milk — is broken down during fermentation into simpler sugars — glucose and galactose ( 20 ).
Microbial fermentation takes place within the gastrointestinal tract of the majority of the animals by the bacterial cells, this helps in the process of digestion and in the synthesis of certain essential components like vitamins.
• The enzymatic decomposition and the usage of food components, mainly carbohydrates by the help of microbes like bacteria anaerobically is termed microbial fermentation.
• Within the gastrointestinal tract of the majority of animals, the process of fermentation takes place, however, the intensity of fermentation depends on the quantity of bacterial cells present, which is usually greatest in the intestine.
• The process of fermentation within the intestine by bacteria primarily helps in the process of metabolism and digestion of carbohydrates that does not get digested in the small intestine like residual starch and cellulose.
• Apart from this, microbial fermentation also helps in the production of vitamin K and some B vitamins.
Thus, microbial fermentation within the intestine of the majority of the animals performs essential functions like digestion and production of vitamins.

In a certain species of plant, the color purple (P) is dominant to the color white (p). According to the Punnett Square, what is the probability of an offspring being purple?
Answers
Answer:
If both are (PP and ww) and one is dominant the other is recessive then it is 100% purple.
IF both are heterozygous (pw) then it is 75% purple and 25% white
if one is Hetro(pw) and the other is (ww) 50% white 50% purple
Explanation:
Most species of E. Coli are harmless or even helpful forms of bacteria that are found in the human intestine. E. Coli can aid humans in digestion and provide protection from other invading bacteria, but if the bacteria move to the human excretory system, they can replace other naturally occurring bacteria (Lactobaccilli). This can lead to bladder and kidney infections. Researchers found that by replenishing the excretory system with the naturally occurring bacteria, the infection caused by E. Coli is cured. Based on the research, what inference can researchers claim about the effect of bacteria?
Answers
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.
