Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?
a
snRNA
b
tRNA
c
mRNA
d
rRNA
The RNA molecule that is involved in translating a short sequence of RNA into an amino acid is tRNA (Option b). This molecule (tRNA) is fundamental to link the genetic information from DNA to protein.
During gene transcription, a fragment of DNA called gene is used as a template to create a complementary messenger RNA (mRNA).
Subsequently, this mRNA is n then used as template to create a polypeptide (i.e., a protein) by a process called translation.
During translation, triplets of nucleotides or 'codons' in the mRNA sequence interact with anticodons of the transfer RNAs (tRNAs), which then specify the linear order of amino acids that will be added to the growing polypeptide.

GIVING BRAINLY! A car started accelerating and it gained speed at 2 m/s2. The car had a mass of 200 kilograms; calculate the average force the car was traveling at.
Answer: ____ Newtons
Answer:
100 Newtons
Explanation:
The car was traveling at an average force of 400 Newtons. This is the force that was being applied to the car to cause it to accelerate at a rate of 2 meters per second squared.
What is force?In physics, force is a measure of the interaction between two objects that can cause a change in the motion of one or both objects. Forces can be classified as either contact forces, which involve physical contact between two objects, or non-contact forces, which involve the interaction of objects without physical contact.
To calculate the average force that the car was traveling at, you can use the equation for average force:
average force = mass x acceleration
Plugging in the values given, you get:
average force = 200 kg x 2 m/s2 = 400 N

When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere. This phenomenon is known as
- climate change
- global warming
- greenhouse effect
- positive feedback
Answer:
Greenhouse effect
Explanation:
When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere; this phenomenon is known as the "greenhouse effect," which is present in the third option.
What is the greenhouse effect?When solar energy strikes the earth, some of it is reflected back and some is trapped in the atmosphere's gaseous layer, such as carbon dioxide; water vapor traps this radiation and warms the earth. Global warming is seen as having serious consequences due to its warming nature, including the melting of the polar ice, agricultural destruction, and so on.
Hence, when the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere; this phenomenon is known as the "greenhouse effect," which is present in the third option.

The patient, a 12-year-old boy, shows several areas of tooth decay: #3 mesial, #12 occlusal, #20 occlusal, and #30 on the occlusal and buccal surfaces. His mother expresses concern about the amount of decay and asks the dental assistant what can be done to prevent more problems. How should the dental assistant respond?
Since the amount of decay is too much, the dental assistant should respond by advising the mother of the patient to reduce the quantity of sugary food intake and to enhance oral hygiene.
A dental assistant is an individual that are usually certified to assist dentists during dental treatment procedures.
During a dental procedure, they help to perform the following tasks:
preparing patients for the treatment, passing dentists instruments and other materials, and keeping patients' mouths dry and clear using suction and other devices.
Tooth decay is the formation of a hole through the tooth cavity.
Tooth decay can occur in several areas when there is poor oral hygiene and excess intake of sugary foods.
When sugary food is taken in excess without proper oral hygiene, it reacts with plaque bacteria in the mouth producing acids.
The acid then dissolves your enamel slowly, creating the cavities in your teeth.
Therefore, the dental assistant should respond by advising the mother of the patient to reduce the quantity of sugary food intake and to enhance oral hygiene.

Describe how the structure of a leaf fits its function.
Answer:
Leaves are thin, minimising the distance for carbon dioxide to travel into leaf cells. A midrib provides strength throughout the leaf, keeping it upright and sturdy in the wind. Chlorophyll is the green pigment that absorbs sunlight. Veins transport water and glucose around the plant.

show that respiratory gaseous exchange in a rabbit occurs at the level of lungs
No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.
