If all cells in your body contain the same DNA why do they perform different functions. Pls help
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

When the process of mitosis is correctly completed, the daughter cells should contain exact copies of all of an organism's genes. Which biomolecule contains all of an organism's genes?
Answer: nucleic acids
Explanation:
During division, the code for the protein cytochrome-C had the code for proline
changed to the code for leucine. This type of change in the genetic material is
known as a -
A. redundant mutation
B. frameshift mutation
C. point mutation
D. chromosomal mutation
Answer:
Point Mutation
Explanation:
The type of change described, where the code for proline is changed to the code for leucine during division, is known as a point mutation. The correct option is C.
A point mutation refers to a change in a single nucleotide base of the genetic material (DNA or RNA).
In this case, the change occurred at a specific position in the genetic code, resulting in the substitution of one nucleotide for another. This substitution led to a different amino acid being incorporated into the protein sequence.
Thus, based on the description provided, the correct answer is C. point mutation, as it involves the specific substitution of one nucleotide for another in the genetic code.

What happens during the first two stages of cellular respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

Pick only ONE sentence Which sentence from the section shows why the right temperature is important for plants? (A) Temperature can also affect a plant (B) As with any living thing, a plant has an optimal temperature range at which it grows and preforms best (C) It may not be able to take in enough water and nutrients through it's roots (D) Too much heat can cause plant cells to break down, a process called denaturation.
Answer:
The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.
Explanation:
Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.
Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

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?
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

Describe an example of fermentation that occurs in beneficial bacterial cells within animals and explain why it is important.
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.
