Answer the following using directional terms specific to the dentition. a Your canine is _______________________________________ relative to your first molar. b Your third molar is __________________________________ relative to your second molar. c The cheek side of the tooth row is the ______________________________ side. d Your lateral incisors are _________________ relative to your central incisors. e The tongue side of the tooth row is the ____________________________________ side. f Where your opposite tooth rows meet (to chew) is the _______________________________ surface.
Answer:
The correct answer is - a. mesial, b. distal c. buccal d. distal e. lingual f. occlusal.
Explanation:
Mesial is the surface near the midline of the face, In dentistry, the canine is mesial to the first molar which means it is the middle of the face. The third molar is distal to the second molar.
Distal is the backside of a particular tooth in dentistry. The cheek side of the tooth known as the facial surface for the front teeth in dentistry. Lateral incisors are distal to the central incisors. Lingual is the part of the tooth near the tongue. The chewing surface of posterior teeth is also known as the occlusal.

Explain the difference between inter-cooperation and intra-cooperation between species.
Answer:
In evolution, co-operation is the process where groups of organisms work or act together for common or mutual benefits. It is commonly defined as any adaptation that has evolved, at least in part, to increase the reproductive success of the actor's social partners. For example, territorial choruses by male lions discourage intruders and are likely to benefit all contributors.
This process contrasts with intragroup competition where individuals work against each other for selfish reasons. Cooperation exists not only in humans but in other animals as well. The diversity of taxa that exhibits cooperation is quite large, ranging from zebra herds to pied babblers to African elephants. Many animal and plant species cooperate with both members of their own species and with members of other species.

Which of the following is true of Mendelian inheritance
A. If a dominant allele is present, the recessive allele won’t be seen
B. If a recessive allele is a present, the dominant allele won’t be seen
C. Both recessive and dominant alleles show if present
The correct option is A. If a dominant allele is present, the recessive allele won’t be seen.
The dominant allele is the one which appear, and the recessive one isn't shown.
For example - If a person has 2 alleles of eye colour as B ( black ) and b ( brown ), in which black is dominant and the brown one is recessive, then the person will have black eye colour because only dominant allele shows its characteristics.

Researchers think the cheetah population in Africa experienced extremely low numbers around 10,000 years ago, and then also again around 100 years ago. During both times, the low numbers rebounded back. Predict the consequence of this on the cheetahs of today.
a. Cheetahs are a very resilient population and unlikely to become extinct.
b. Cheetahs today are the strongest and fastest cheetahs ever.
c. Cheetahs today have very little genetic variation.
d. Cheetahs today are slower than those before the population fell.
Answer:
Cheetahs are a very resilient population and unlikely to become extinct.
Explanation:
LH Gunderson (2000) Defined ecological resilience as "the amount of disturbance that an ecosystem could withstand without changing self-organized processes and structures."
When a population is resilient, it tends to bounce back after major perturbations.
For instance, the Cheetah population was at the brink of extinction around 10,000 years ago, and then also again around 100 years ago yet the population was able to recover at both periods and never went extinct.
This implies that Cheetahs are a very resilient population and unlikely to become extinct.
Answer:
c. Cheetahs today have very little genetic variation
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
In the exposed example, the low numbers of cheetah around 10,000 years ago, and then also again around 100 years ago, might have been due to some natural disaster or extensive hunting that acted as a pressure that significantly reduced the number of animals. Probably, the population experienced one or many small-sized generations. Even though the low numbers rebounded back, the survivors did not have the whole genetic pool of the original population, meaning the genetic diversity might not have recovered. When the small groups increased in size, they had a genetically different composition from the original one. There is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It might involve even more individuals each time and increase the probability of developing a genetic disease.

Answer:
Bioindicators
Explanation:
Answer:
Indicator species and/or keystone species
Explanation:
Indicator species are species (e.g., plants, animals, fungi) that can be utilized to determine changes in the environment. An indicator species can show the impact of pollution on an ecosystem. For example, mosses are indicator species that indicate the acidity in the soil. Moreover, keystone species are species that maintain the ecological balance in the ecosystem. When a keystone species is removed, the entire ecosystem is dramatically changed or may even cease to exist altogether. In consequence, keystone species can be used to define an entire ecosystem. For example, bees are a keynote species that contributes to balance the ecosystem by pollinating plants.
Which situations would be most likely to engage the anterior cingulate cortex?
Answer:
Which of the following situations would be most likely to engage the anterior cingulate cortex?
A waiter walks over to your table at a restaurant and holds an open menu in front of you.
You walk into the elevator of your apartment building and press the button for your floor.
You enter your classroom and find someone sitting in your usual seat.
A good friend asks you to remind him of your telephone number.
Explanation:
In order to meet the demand of the surrounding environment by adjusting the motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.
Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.
Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and possessing of memory and learning.
it is also a major parts of of pain networks for pain modulation and perception.
Therefore whenever there is change in the environment from the prestored condition in the brain,(e.g the usual seat in the class room occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case leads to the reclaiming of the seat or any other necessary proactive action.

The researcher hypothesizes that the FXR1 gene codes for a protein that binds to mRNAs that encode some of the proteins that damage arteries. Individuals with a particular mutation of the FXR1 gene tend to have high levels of these proteins. Based on this information, predict how the FXR1 protein most likely interacts with the mRNAs.
Answer:
it is expected that FXR1 interacts with mRNAs by inhibiting them before they are translated into the ribosomes, thereby preventing the production of proteins that cause damage in the arteries.
Explanation:
The translation is the cellular process in which a messenger RNA (mRNA) is used as template to synthesize a protein in the ribosomes. During translation, ribosomes catalyze the reaction that joins amino acids in order to create a polypeptide chain (i.e., an ordered sequence of amino acids). Diverse types of either synthetically or naturally occurring molecules can inhibit protein production at the level of translation (e.g., siRNAs, proteins, drugs, etc). In this case, it is expected that FXR1 inhibits the mRNAs that encode proteins capable of causing damage in the arteries, thereby a mutation that results in reduced and/or abolished FXR1 function (i.e., a loss of function mutation) will lead to a phenotype with high levels of these proteins.
Binding of FRX1 protein to mRNA will block the translation process of mRNA, thereby inhibiting protein synthesis.
What is the function of mRNA in protein synthesis?mRNA or messenger RNA is made from the transcription of DNA and the information stored in it is translated into amino acids by ribosomes in the process of protein synthesis.
Thus, mRNA serves as a template for protein synthesis.
How does the FRX1 protein interact with mRNA?The binding of the FRX1 protein will most likely block access to the codons present in the mRNA from being read by tRNA, thus inhibiting the synthesis of the proteins that damage arteries.
Therefore, binding of FRX1 protein to mRNA will block the translation process of mRNA, thereby inhibiting protein synthesis.
