Answer:
its transcription
Explanation:
The process shown in the diagram is called transcription.
Transcription represents the first stage of protein synthesis. During this process, genetic information on DNA templates are transcribed to genetic codes in the form of messenger RNA.
The transcription process starts with the binding of the RNA polymerase enzyme to the promoter region of a gene. This causes the unwinding of the double helix structure of DNA in the binding region. Thereafter, the RNA polymerase starts synthesizing the complementary bases of the DNA template.

what happens if stomach is removed
Answers
Answer: you die
Explanation:
Answer:
What happens after your stomach is removed?After surgery, the way you eat and digest food will change, and it’s important that you carefully follow your doctor’s recommendations for eating to ensure your body is absorbing much-needed nutrients.“It is important to try to consume as many calories as possible to minimize rapid weight loss in the first few months following surgery, and to take in nutrients that the body needs to aid in the healing process,” said Jeffrey M. Farma, MD, FACS, a surgical oncologist at Fox Chase Cancer Center.“Eventually the desire to eat and enjoy food will return,” he said.Eating after your gastrectomyWithout your stomach, you aren’t able to handle regular portions of food and may not even feel hungry. Even if you are not hungry, it is important to remember that nutrition is a vital part of your health.You will need to eat smaller amounts of food more often – six to eight small meals a day. Your doctor or nutritionist may also recommend that you stay upright for some time after eating. Your health care team can help you adjust your diet if you are having problems eating.Some patients may experience a condition called dumping syndrome. When part or all of the stomach is removed, the food that is swallowed quickly passes into the intestine, leading to problems with nausea, diarrhea, sweating and flushing after eating. There are treatments to help with these symptoms.“Since the stomach is no longer there to do the grinding and breakdown of food, it is important that patients take small bites and thoroughly chew the food,” Farma said.Maintaining your weight without a stomachConsuming enough calories to return to your favorite activities will happen over time. Nutritious, high calorie, low sugar foods provide the best bang for the bite. Calories are your body’s first priority.“You will not be able to eat the same quantity of food as you did before your surgery, so it is important to get the calories in smaller amounts of high calorie foods,” Farma suggested.Dietary guidelinesEat a variety of foods including fruits, vegetables, whole grains, protein-rich foods and dairy, which provide a good balance for every meal.Try not to go for more than 2 or 3 hours without eating.Carry healthy snacks so you can take a bite here and there.Nutrient-dense liquids can provide needed calories and are sometimes easier to consume than solid foods. Consider drinking milk, eggnog or unsweetened juice instead of coffee, tea or water.While you can’t change the fact that your digestive system is different, you can change your diet and lifestyle to enjoy a full and rewarding life after surgery.which is a gemete?

If species are not changing, is it true to say that natural selection is not happening? Explain your reasoning
Answers
Answer:
true
Explanation:
ki
Answer:
Species are changing, natural selection is happening
Explanation:
There are many small, unnoticeable changes occuring in animals everday. Depending on whether these changes are helpful or unhelpful, the animal and its special features, will either be eliminated (through the process of natural selection) or embraced by others. If the traits are helpful, and therefore more dominant/attractive, it will ultimately lead to a split off, more dominant group of animals that all have the same adaptation, which allows the animals to out perform others.
**The reason you can't always see natural selection is because it's often a slow process. Also, if an animal's mental or physical traits change for the worse, the animal doesn't always live a full life, and doesn't reproduce. If the animal with the new traits doesn't reproduce (because the traits are not helpful and therefore unwanted), then that animal's traits are not allowed in the environment.**

You wish to determine the concentration of bacteria in a liquid sample. You measure the concentration by direct microscopic observation and by the plate count technique. Which method would give you a more accurate count of viable (i.e. living) bacteria in the sample
Answers
Answer:
The correct answer to the question above is "PLATE COUNT TECHNIQUE"
Explanation:
DIRECT MICROSCOPIC OBSERVATION is the method of estimating the number of microorganism using microscope. Samples to be estimated are placed on microscope slides which allow few cells in a small volume to be counted. Then, the value determined is used to estimate the total number of cells mathematically. It is only difficult to aee small cells which may affect precision.
VIABLE COUNT is the estimation of the living cells in a given sample.
PLATE COUNT TECHNIQUE is used to estimate the number of viable cells that are present in a given sample of actively growing or dividing cells based on bacteria cells found on agar plate. A sample to be counted is diluted in a solution that will not kill the microorganisms, this is done to enable accurate counting as only living bacteria will be counted.

What is earthquake and its causes?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates.

A student described his new pet dog to his friends. Which part of his description identifies an acquired trait of his new
dog?
Answers
Answer:
You did not enter the description of the dog, which does not allow me to tell you specifically which characteristic of the dog is acquired, but I can help you. This is because the characteristics acquired are those that are not hereditary, that is, a stain on the dog's ear or a bruise on its paw, for example, are a type of acquired characteristics.
Explanation:
As you may already know, hereditary characteristics are those that are passed from parents to children, through genetic factors. However, not all characteristics that living beings have are inherited. This is because there are the acquired characteristics, which are created by the environment over time and which are not passed on to descendants.
If your dog went to the pet shop and received a pink paint on his coat there, this is an acquired characteristic. The same is true if your dog has a bruised foot, or if there is a spot on its ear that is not related to the dog's genes.

Consider aerobic cellular metabolism from the beginning to end. What is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and ATP?
Answers
Explanation:
This starts with substrate level phosphorylation(glycolysis) in the cytosol of cytoplasms.Two ATPs are needed for phosphorylation of glucose.With eventual formation of 4 ATPs with 2NET GAIN ATPs,NADH+,and Pyruvate.
The Pyruvate reacts with co-enzyme A to form Acetyl coA-This is the bridge reaction or link reaction.
The Acetyl Co-A diffuses into the mitochondria where it combines with oxaloacetate to form citrate,the latter form Alpha ketoglutaric succinic,fumate,malate and back to oxaloacetate.The cycle of events is called the Kreb's Cycle.
Net of 2ATPs are formed,co-enzymes NADH+ and FADH2 ,water molecules,and Co2 are produced.These takes place in the mitochondria.
Then the NADH+ and FADH2 takes the hydrogen ions into the inner mitochondria where Hydrogen is split into electron and Protons.This forms the beginning of oxidative phosphorylation.
The electrons are transmitted by the carrier proteins to form the electron transport chains,which provide the PMF. The latter pumps the protons across the walls of mitochondria into the intramembrane space.
The high concentration of the protons produce the elecrochemical gradients which make the protons to diffuse back into the matrix. it is the changes in the elctrochemical gradients that supply the energy needed by ATPase enzymes for synthesis of ATPs. A total of 28ATPs are produced in oxidative phosphorylation.
Answer:
The total ATPs produced in the sequence of glycolysis pyruvatre,Co-enzyme A, kreb's Cycle and oxidative phosphorylation are 32ATPs per molecule of glucose splits in Glycolysis.

If a man has red-green color blindness, a sex-linked dominant trait, what is a possible genotype of his father? I. XR Y II. Xr Y III. XR XR IV XR Xr A. Only III B. I and III C. I and II D. I, III, and IV
Answers
Answer:
C
Explanation:
The possible genotype of his father is [tex]X^RY[/tex] and [tex]X^rY[/tex].
For sex-linked traits, an affected man always inherit the affected allele from the mother. The other chromosome, which is the Y chromosome is always from the father and this confers maleness on individuals.
The father of a man affected for a sex-linked trait can be affected for the same trait or otherwise. It does not have any bearing on the male child since the father only donates the Y chromosome to the male child.
Hence, in this case, the father can either be affected for the same trait ([tex]X^RY[/tex]) or be free from it ([tex]X^rY[/tex]).

Amanda gets protein at lunch by eating a chicken sandwich. How can Amanda’s body use the protein in the chicken to build protein in her cells?
Answers
Answer:
- The proteins in the chicken are broken down into amino acids, and the DNA in Amanda's cells uses those amino acids to build human proteins.
Explanation:
The body uses the protein taken by Amanda in the form of a chicken sandwich by breaking it down into the form of compounds called 'amino acids.' Amino acids are described as the substances that are responsible for the formation of proteins in the body. Thus, the DNA present in Amanda's body cells will use these amino acids to form human proteins. The longer chains of these amino acids help the body to ensure its proper structuring and functioning.
The proteins can be broken down into amino acids, and Amanda used her genetic material (DNA) to build proteins from these amino acids.
A protein is a long chain of amino acids linked by peptide bonds.During gene transcription, a specific fragment of DNA known as gene is used to create an mRNA, which is then used to create a protein by a process called translation.The linear order of nucleotides in DNA determines the order of amino acids in the protein sequence.In conclusion, the proteins can be broken down into amino acids, and Amanda used her genetic material (DNA) to build proteins from these amino acids.

strand with anticodons, which are attached to tRNA and carry amino acids.
Codons consist of how many bases or "nucleotides"? *
Answers
The process of translation involves the joining of codons on the mRNA with anticodons of tRNA that carry amino acids. Codons consist of three consecutive nucleotides present on mRNA.
What is translation?Translation is the process of forming polypeptide chains by reading the nucleotides (codon) of mRNA. The three consecutive nucleotides make up a codon. Example is AUG.
The tRNA has an anticodon site that reads the codons of the mRNA. The tRNA carries an amino acid and synthesises polypeptide chains by reading the codons of mRNA. Example: The AUG codon codes for methionine amino acids.
The tRNA reads the mRNA from the 5' end to the 3' end. In this translation process, ribosomes and other translation proteins are involved. Due to translation, the gene in the DNA is expressed.
Hence , the codon is made up of three consecutive nucleotides present on mRNA. This is attached to the anticodon of tRNA, and a polypeptide is synthesized.
