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.

The weaker the stimulus received by the neuron,
A. the stronger the action potential
B. the weaker the action potential
C. the stronger the local potential
D. the weaker the local potential
The weaker the stimulus received by the neuron,the weaker the action potential. That is option B.
What is action potential?Action potential is defined as the signals generated by neurons which is an electrical activity caused by a depolarising current in the neuron.
Practically, the greater the strength of a stimulus, the greater the number of action potentials generated in a nerve cell.

After transcription and translation, does the mutation that was in the DNA change the amino acid that the second codon specifies?
Given what we know about genetic mutation, we can confirm that unless the mutation is of the silent type (and sometimes regardless of this), it will in fact change the amino acid that the codon specifies.
Mutations are changes in the DNA sequence of a cell that occur during the replication phase. Cellular mutations can be of many types, such as:
Insertion DeletionSubstitutionInversionand so on, each of which can have varying effects on the amino acid produced.
Most mutations will affect the resulting amino acid in some way. Insertion and deletion tend to be the most harmful mutation types as they alter the way in which the genetic code is processed. Some mutations, however, can be silent, meaning they have no harmful effects due to the fact that the new sequence either encodes the same amino acid or one with a similar enough function. This is possible through mutations like substitution.
Substitution mutations change one nucleotide in a sequence for another. At times, the new sequence will actually encode for the same amino acid as before despite the change. This is one of the only situations in which the amino acid will not be changed. Most often, if a mutation occurs, we can expect the resulting amino acid to change.

3. In my opinion, the use of archetypes in a story like "The Apple Tree" isn't lazy or unimaginative. This is because of various reasons, mainly being that it is extremely hard to come up with anything completely original. Chances are that anything you think of has already been thought of, made, or in the process of being made. I believe as long as something isn't completely copying something else, then it is okay for it to exist. For example, "The Apple Tree" and the story of Adam and Eve follow the same plot archetype and are similar in many ways. But the two stories talk about two very different concepts. I believe it is okay to take inspiration from something else because that is how evolution works, and without evolution, humans wouldn't be where they are today.

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.

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.
