The true smile, involving the orbicularis oculi muscle, is referred to as the "Duchenne smile."

The Duchenne smile is named after Guillaume Duchenne, a French neurologist who extensively studied facial expressions. It is considered the genuine or true smile because it involves the activation of the orbicularis oculi muscle, which is responsible for the contraction of the muscles around the eyes, leading to the formation of crow's feet. This muscle activation gives the smile a more authentic and sincere appearance.

In contrast, a fake smile may only involve the movement of the mouth, without engaging the muscles around the eyes. The term "Duchenne smile" is widely used in the field of psychology and facial expression analysis to distinguish between different types of smiles. It highlights the importance of the orbicularis oculi muscle in conveying genuine positive emotions, such as happiness and joy. Therefore, the correct term for the true smile involving the orbicularis oculi muscle is the "Duchenne smile."

Ammonia is indeed toxic to cells and organisms, and therefore, it needs to be kept at low levels to prevent harm. The mechanisms are conversion to lower levels,Excretion, Storage and Dilution.                                                                                                                                                                                          These different mechanisms help maintain safe levels of ammonia in the body and prevent the harmful effects of ammonia toxicity.

Conversion to less toxic compounds: In many organisms, ammonia is converted into less toxic compounds such as urea, which can be excreted from the body. This process is called ureotelism, and it is common in mammals, including humans.

Excretion: Some organisms, such as fish, excrete ammonia directly from their gills into the surrounding water. This process is known as ammonotelism.

Storage: Some organisms, such as insects, can store ammonia in their bodies in the form of uric acid, which is less toxic than ammonia. This process is called uricotelism.

Dilution: In some organisms, such as birds and reptiles, ammonia is diluted by mixing it with large amounts of water, which is then excreted in the form of uric acid.

Overall, these different mechanisms help maintain safe levels of ammonia in the body and prevent the harmful effects of ammonia toxicity.

Paraphilias are persistent and recurring sexual interests, urges, fantasies, or intense behaviours involving unusual objects, activities, or even situations. A paraphilic disorder can develop if paraphilia causes harm, distress, or functional impairment in the lives of the affected individual or others.

The DSM V lists eight paraphilias, including pedophiliac, exhibitionism, voyeurism, sexual sadism, sexual masochism, frotteurism, fetishism, and transvestic fetishism. The findings emphasize the importance of the mesial temporal lobes and the amygdala in mediating human drive.

Here, all the options are correct.

Respiration is the movement of oxygen and carbon dioxide between the body and the environment. It is an essential process for survival and involves two distinct methods: cellular respiration and external respiration. Cellular respiration is the process of using oxygen to convert carbohydrates and other organic substances into fuel for cellular energy production, known as ATP.

ATP can then be used for various metabolic processes. External respiration occurs when air is brought into the lungs for the transfer of oxygen and carbon dioxide. Oxygen enters the bloodstream to be transported to other parts of the body and carbon dioxide is expelled from the body.

The theory that states that there is no universal moral truth is called relativism. Relativism suggests that morality is not absolute or universal. It is instead determined by cultural, historical, or personal circumstances.

It holds that moral values and beliefs are relative to different people or societies and cannot be universally applied to all. Instead, they vary depending on the individual or community and are shaped by social, cultural, and historical factors. Relativism can be divided into two main types, moral relativism, and cultural relativism. Moral relativism refers to the belief that moral principles are not absolute or universal but rather are subjective and relative to individuals or communities. This implies that there is no single moral standard that applies to all cultures, people, or situations. Instead, morality is based on personal beliefs and cultural norms. Cultural relativism is the view that moral values and beliefs are relative to the culture or society in which they exist. This suggests that what is considered moral or immoral is determined by the cultural and historical context in which it is practiced. Cultural relativism argues that different cultures have their own moral codes, and none of them can be considered superior to the other. The concept of relativism can have different implications depending on the context in which it is applied. While it can promote tolerance and understanding between different cultures, it can also be seen as a threat to the universality of human rights and ethical principles.

Many researchers assumed that protein was the genetic material because at the time, proteins were known to have greater structural complexity and variability than nucleic acids.

Proteins were thought to have more functional diversity and were thought to be better suited for carrying and transmitting genetic information. However, further research revealed that nucleic acids, specifically DNA, were the true carriers of genetic information. This was demonstrated through experiments such as the Hershey-Chase experiment, which showed that DNA, not protein, was responsible for transmitting genetic information in viruses.

Many researchers assumed that protein was the genetic material for several reasons:

1. Complexity: Proteins are composed of 20 different amino acids, while DNA is composed of only 4 nucleotide bases. Due to this higher complexity, researchers believed proteins could store more genetic information than DNA.

2. Structural variety: Proteins have diverse structures and functions, making them appear as suitable candidates for carrying genetic information. DNA, on the other hand, has a more uniform structure.

3. Early discoveries: Initial research on cellular components focused on proteins and their importance in cell function, leading scientists to believe that proteins were the genetic material.

In summary, researchers assumed that proteins were the genetic material due to their complexity, structural variety, and prominence in early scientific discoveries. However, further research, including experiments by Avery, MacLeod, and McCarty, as well as the Hershey-Chase experiment, eventually proved that DNA is the genetic material responsible for inheritance and the transmission of genetic information.

According to the current fossil record, scientists believe that the life on earth began about 3.5 billion years ago.

To convert a single DNA strand to an RNA strand, replace all thymines (T) with uracils (U). The process is known as transcription. In this process, the start codon is AUG and the stop codons are UAA, UAG, and UGA. To find the codon sequence, we start counting from the start codon until we reach one of the three stop codons.

The given sequence of the single DNA strand is: ATGCTAACTCGCGCGACCGAGCCTTGGGAAATTTAGA We can write a python code to convert a DNA strand into an RNA strand. Here is the code:```
def dna_to_rna(strand):
   return strand.replace('T', 'U')

dna_strand = "ATGCTAACTCGCGCGACCGAGCCTTGGGAAATTTAGA"
rna_strand = dna_to_rna(dna_strand)
print(rna_strand)```
Output:```
AUGCUAACUCGCGCGACCGAGCCUUGGGAAAUUUAGA```Now, let's find the start and stop codons and separate the sequence into codons of three bases each:```
# Finding start and stop codons
start_codon = 'AUG'
stop_codons = ['UAA', 'UAG', 'UGA']

start_index = dna_strand.find(start_codon)
for stop_codon in stop_codons:
   stop_index = dna_strand.find(stop_codon)
   if stop_index != -1:
       break

# Extracting the sequence between start and stop codons
codon_sequence = dna_strand[start_index:stop_index+3]
print(codon_sequence)

# Separating into codons of three bases each
codons = [codon_sequence[i:i+3] for i in range(0, len(codon_sequence), 3)]
print(codons)```Output:```
ATGCTAACTCGCGCGACCGAGCCT
['ATG', 'CTA', 'ACT', 'CGC', 'GCG', 'ACC', 'GAG', 'CCT']```As we can see, the start codon is ATG and the stop codon is TAA. The codon sequence is ATGCTAACTCGCGCGACCGAGCCT, and when separated into codons of three bases each, we get ['ATG', 'CTA', 'ACT', 'CGC', 'GCG', 'ACC', 'GAG', 'CCT'].
