Which of the following processes takes place in the ribosomes of a cell
Answer:
protein synthesis
Explanation:
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?
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.

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
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 causes an ionic bond to form between sodium and chlorine ?
Answer:
They combine as atoms, and separate as ions.
Explanation:
When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. ... Because the sodium ion has a positive charge, and the chlorine ion has a negative charge, they are attracted to each other, and form an ionic bond.
The elements are well suited to bind with one another since sodium has a tendency to lose an electron while chlorine has a tendency to gain an electron. Thus, option D is correct.
What is the process of formation of ionic bond in NaCl?Atoms absorb or lose electrons to generate ions in ionic compounds. For instance, sodium and chlorine are used to create table salt.
Each element's atoms are electrically neutral when they first combine. An electron is transferred from the sodium to the chlorine when they are close enough.
The establishment of the ionic bond that holds Na+ and Cl- together is the result of this transfer of electrons.
An electron is transferred when sodium and chlorine atoms combine to form sodium chloride (NaCl).
They are drawn to one another and create an ionic bond because the sodium ion has a positive charge and the chlorine ion has a negative charge.
Therefore, sodium atom donate electron.

What happens to a population when the death rate decreases?
A. The birthrate usually increases.
B. The population size usually increases.
C. The population size usually decreases.
D. The birthrate usually decreases.
Answer:
B. The population size usually increases.
Explanation:
You can predict the growth rate by using this simple equation: growth rate = birth rate – death rate.
If the birth rate is larger than the death rate, then the population grows.
The population size will decrease.
If the birth and death rates are equal, then the population size will not change.

A student described his new pet dog to his friends. Which part of his description identifies an acquired trait of his new
dog?
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.

C. A loud noise startles native animals.
D. More light reaches shorter plants.
Answer:B
Explanation: When storm wind occur it makes trees fall to the ground and in some cases wildfire occurs.
The effects of the storm winds which removes major habitats is the trees which fall on the ground and die. Thus, the correct option is B.
What is Tree ecosystem?A natural woodland area or a tree ecosystem makes a suitable place for the survival of both the biotic and abiotic components of the environment. It is usually termed as a forest ecosystem.
The effects of storm winds falling trees is severe, as it creates more light to reach the shorter plants which will help the plants to do photosynthesis well, which will even facilitate their fast growth and this is positive impact. However, falling down and death of the tree is a negative impact on the ecosystem as a number of different species lives on the tree.
Fallen trees becoming the food for decomposers can also be a positive cause which will help the soil or the earth to increase the fertility and produce more healthy organisms.
Therefore, the correct option is B.

Quarterly time frame best describes when earthquakes occur.
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.

what happens if stomach is removed
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.1 point
The process of translation involves the joining of codons on the mRNA
strand with anticodons, which are attached to tRNA and carry amino acids.
Codons consist of how many bases or "nucleotides"? *
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.
