1. Construct an Explanation Based only on the information provided, why could the
mRNA section be translated into three different sets of amino acids, instead of just one
set?
2. Use Models Use the genetic code to translate the sequence into each of the three
possible sets of amino acids.
3. Draw Conclusions Which of the three sets of amino acids is the most likely to be
included in the polypeptide? Explain your reasoning.
Answers
Answer: three sets: ile. leu,phe,cys,leu,glu. glu,ile,cys,leu,val,asp,leu
The most likely sequence to be included is the R to L read, because of the STOP codon if read L to R. The lone ile would be the last amino acid of a different polypeptide, and there is no promoter sequence after the STOP codon.
Explanation:
auu,uaa,cug,uuc,ugu,cua,gag
Ile,STOP,leu,phe,cys,leu,glu
glu,ile,cys,leu,val,asp,leu (reverse)
After a STOP codon, a DNA promoter is required
Codons are the trinucleotide sequence found in the DNA and RNA. These codons code for specific amino acids and describe the relationship between the nitrogenous bases of the DNA.
1. Codon is the set of three nucleotides, in which amino acids can be coded by different codons.
In the given sequence, the mRNA can translate the sequence into more than one set as the sequence must contain a promoter and a stop codon.
2. In the given set, the possible amino acid sequences can be given as:
Glutamic acid, isoleucine, cysteine, leucine, valine, aspartate, leucine
Isoleucine, Ochre, Leucine, Phenylalanine, Cysteine, Leucine, Glutamic acid
3. The codon sequence, which has a promotor sequence after a stop or start codon will have more chances to be translated during the process.
In the given sequence:
Isoleucine, Ochre, Leucine, Phenylalanine, Cysteine, Leucine, Glutamic acid
The polypeptide will be stopped due to the presence of a stop codon in the polypeptide.

What is cellular respiration?A series of chemical reactions known as cellular respiration breaks down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation.
In eukaryotes, the 4 phases of cell breath incorporate glycolysis, progress response (pyruvate oxidation), the Krebs cycle (otherwise called the citrus extract cycle), and oxidative phosphorylation through the electron transport chain.
Therefore, cellular respiration is the main process that generates ATP and gives energy to the body to work.

Evaluate the evolutionary benefits of regulating an internal variable, such as body temperature, versus the cost.
Answers
Answer:
The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.
Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.
This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.
Explanation:
Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.
why would an athlete need to be concerned about a twitch or sustained contraction
Answers
Answer:
why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.

In organisms other than plants, when and where is the most ATP produced?
in cytoplasm, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration
Answers
Answer:
D. In mitochondria, during cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.

Agricultural revolutionAgriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.
With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.
The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in
compost bins, forming a dirt-like substance that's rich in nutrients. The next season, farmers use this
substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer
formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in
unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to
grow faster and taller than his artificial fertilizer. Explain independent and dependent variables
Answers
Answer:
Please find the explanation of independent and dependent variables below using the experiment in this question.
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.
According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.
In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.
