A particular triplet of bases in the coding strand of DNA is AAA. The anticodon on the tRNA that binds this mRNA codon is _____.
Answer:
UUU
Explanation:
A codon consists of three nucleotide bases that codes for a specific amino acid.
In the process of protein synthesis, information encoded in the messenger RNA is transferred from it by the tRNA to the rRNA of ribosomes for protein synthesis. Each transfer RNA (tRNA) has an anticodon which can base pair with a codon.
An anticodon consists of three nucleotide base sequence that is complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence.
Since in RNAs, uracil, U, is complementary to adenine, A, the anticodon on the tRNA that binds to the mRNA AAA codon is UUU.

A student places a healthy potted plant and a plastic straw in a closet for two weeks. After two weeks, the student observes that the plant is wilted and brown, while the plastic straw remains the same.
The student classifies the plant as living and the plastic straw as nonliving,
What criteria does the student use to classify the plant as living rather than nonliving?
The plant needs energy from sunlight to make food for survival.
The plant produces pollen for reproduction of its species.
The plant generates sugars that are consumed as food by other organisms.
The plant produces offspring with characteristics similar to the parent plant
Answer:
According to the experiment, the criteria used by the student to classify the plant as living rather than non-living is that plant needs energy from sunlight to make food for survival.
Explanation:
One of the characteristics that defines plants as living is their ability to perform functions proper to living beings, such as nutrition, growth, development and reproduction.
Plants are autotrophic organisms, capable of producing their own nutrients from sunlight, so they require this type of energy for their nutrition and survival.
The fact that the plant that remained in the closet for 2 weeks turned brown and wither demonstrates the need it has for sunlight, which is a valid criteria for considering it a living being, in comparison with the non-living object.
The other options are characteristics of plants as living beings, but they are not the criterion that demonstrates that plants are living beings, in accordance with the proposed scenario.

You are about to be sent to a remote area by WHO where you will be working with infectious diseases caused by a variety of microorganisms. You will be using what you know about the chemistry underlying biological processes in microbes and infections to solve the case on Rabbit Island. What will you need to know
Answer:
Pathology of any infectious disease required some basic information to understand the biology and physiological process of the microbes, these information are given as follow:
Mode of pathogenesis
range of the affected organ or tissues
The incubation period, latent period and extent of infection
Physiological change in the infected organ or tissue
Doubling time of microbe in the host
The resistance and sensitivity of microbe against antibodies
Co-infection if any.
Which of the following statements about mycorrhizae is false? Group of answer choices Foresters inoculate pine seedlings with them to promote growth. They colonize soils by dispersing spores that form new mycelia. They are in a parasitic relationship with plants. They are important in natural systems and agriculture.
Answer:
They are in a parasitic relationship with plants.
Explanation:
Mycorrhizae is a fungus root that has a mutually beneficial relationship with roots of the plants and not a parasitic relationship.
Mycorrhizae colonize soil and disperse its thick-walled spores produced on the extra-radicular hyphae. Mycorrhizae are important in natural systems and agriculture as it helps in the regulation of exchange of nutrients and sugar between fungus and plant.
Hence, the correct answers are "They are in a parasitic relationship with plants."

in which two steps of cellular respiration is the co2 produced
Answer:The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.

Which action causes breakers
1 waves hit the shore at an angle and transport sand
2 water flows away from the shore and moves sand with it
3 underwater earthquakes cause motion throughout ocean
4 water waves meet the shore and cause the crest to spill over the trough
Answer:
When a wave becomes too high relative to the depth of the water, it can no longer support its own weight and topples to the shore, resulting in a breaker. Waves Even though it looks as though waves are moving forward, in reality only a relatively small amount of water is displaced, and what you actually see is a transfer of energy..
Answer:
4. Water waves meet the shore and cause the crest to spill over the trough.
Explanation:
A breaker is a wave that has the crest spill over toward the trough as it approaches shore.
When taking a look at this type of pressure map,which represents the sinking air? Rising air?
Students studying potential and kinetic energy designed this experimental set-up. During the initial trial, a ball was rolled down a ramp fro the spot marked "start". The ball rolled down the ramp and then back up the other side, to the spot marked "finish", represented by letter B. The students want to determine the starting point so that the ball will rise up to the point marked by letter A. They release the ball starts at the spot marked "New start" and the ball rolls up the other side to letter A.
This is a controlled experiment. All BUT ONE factor is controlled in this experiment. What is that factor?
A. ball used in trials
B. distance between ramps
C. starting point of release
D. angles of incline for ramps ***
Can someone check this?
Answer:
The correct answer is D) angles of incline for the ramps
Explanation:
The only way the ball which rolled off Starting Point A will roll down an incline and then upwards to a finish point called B is if the angle of incline between A and the midpoint X (which is where the ball starts to roll back up) is steeper than the gradient between B and X.
The higher the gradient of the slope, the faster the acceleration of the ball towards point B from A and vice versa.

In physics, what is a black body?
Answer:
Blackbody, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. The concept of such a perfect absorber of energy is extremely useful in the study of radiation phenomena.
How is the investigation of the Hudson River ecosystem an example of scientific inquiry?
Scientists study the natural world through scientific inquiry. This involves:
• Asking questions
• Developing and using models
• Planning and carrying out investigations
• Analyzing and interpreting data
• Using mathematics and computer technology
• Constructing explanations
• Engaging in argument from evidence
• Obtaining, evaluating, and communicating information
Answer:
The investigation of the Hudson River is an example of scientific inquiry because it develops testable questions such as this; How might a zebra mussel invasion affect the Hudson River ecosystem?
All the other elements of scientific inquiry were applied.
Explanation:
Developing and using models: Scientists developed ways to check for changes in the river using the data available to them.
• Planning and carrying out investigations: Several scientific institutes have planned and carried out investigations to determine reasons for the return of the Zebra mussels.
• Analyzing and interpreting data: Graphs are plotted to evaluate to draw a relationship between the zooplankton and the Zebra mussels.
• Using mathematics and computer technology : Mathematical measurements were done to analyze the sizes of the Zebra mussels.
• Constructing explanations : Explanations were proposed as to why the Zebra mussels were not eating up them. It made sense to them that more Zebra mussels would result in more Zooplanktons
• Engaging in argument from evidence : They could argue from the evidence that blue cobras were eating up the Zebra mussels
• Obtaining, evaluating, and communicating information: After scientists have obtained their information, they endeavor to communicate them by publishing them in scientific papers and journals.
