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.

Answer:
Cold front → blue line/trianglesWarm front → red line/semicircles Occluded front → lines with triangles and semicircles Low pressure → LHigh pressure → H Strong winds, cloudless → White key Strong winds, very cloudy → Black filled keyExplanation:
ISOBARS:
These are lines that join points of similar pressure and indicate atmospheric pressure for different regions. If lines are very close to each other, means that there will be bad weather. This is because, at a short distance, pressure values change, meaning atmospheric instability.
PRESSURE ZONES:
Isobars indicate the speed and direction of winds. Winds move from high atmospheric pressure areas to lower atmospheric pressure areas. When isobars are placed as small circles, there is a letter indicating the pressure center. It can be either high pressure symbolized with an H, or low pressure symbolized with an L.
High-pressure zones, H, represent anticyclones and are associated with good weather.Low-pressure zones, L, represent cyclones and are associated with bad weather. The closer the lines are to each other, the stronger will be the winds.FRONT TYPES:
There are different types of fronts, which can be represented with different symbols.
Cold front: In weather maps, these are represented with blue lines with triangles indicating the direction of the wind movements. Warm front: In weather maps, these are represented with red lines with semicircles indicating the direction of the wind movements. Occluded front: It can be warm or cold. These are represented with purple lines with triangles and semicircles indicating the direction of the wind movements.CLOUD COVER / WIND SPEED:
Indicated as a key figure on the map.
Circle: Represents the percentage of cloud cover. The clouder it is, the more black will be the circle. Stick: Represents the wind speed. The stick can have lines indicating the degree of speed → stick with no transversal line indicates 1-4 mph, one line means 5-8 mph, two lines 9-14 mph.

Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere. Fill in the steps in the path below. Then, label each location with the system it represents. Finally, summarize very briefly how the carbon atom got to that location.
Answer:
Volcanoes, burning fossil fuels, and respiration of organisms.
Explanation:
Volcanoes, burning fossil fuels, and respiration of organisms releases carbondioxide that forms atmospheric carbondioxide. The carbon enters in the biosphere through the process of photosynthesis. In plants, carbondioxide enters in the plant body which is used as a reactant from which food is prepared. The carbon present in the plant body in the form of glucose which can be transferred into another organism due to feeding of organisms. The organism released this carbon in the form of carbondioxide when the eaten food is broken down for the release of energy. In that way, carbon moves from biosphere to the atmosphere whereas Volcanoes and burning fossil fuels releases carbon in the atmosphere, in this way carbon moves from lithosphere to atmosphere.

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.

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.

Which of the following statements about the equilibrium theory of island biogeography is FALSE?
a) All of the above are true; none is false.
b) At equilibrium, the species composition of an island will not change.
c) If the extinction rate increases, the number of species on an island should decrease.
d) If the immigration rate increases, the number of species on an island should increase.
e) The theory applies to island-like habitats as well as islands.
Answer:
b) At equilibrium, the species composition of an island will not change
Explanation:
According to MacArthur-Wilson (1967) equilibrium theory of island biogeography
• The number of species on an island represents a dynamic equilibrium between the opposite forces of immigration and extinction rates.
• At equilibrium, the species richness keeps constant. But the species composition changes.
• Each island can have a certain number of species, but these species are not always the same, meaning that species might renew. Interspecific competition has a significant role.
The assumptions of the equilibrium theory:
The immigration rate depends on the distance of the island to the mainlandThe extinction rate depends on the island size.All the species have the same chances of getting to the island.Predictions:
At equilibrium, the number of species is constant in time.Dynamic equilibrium means a continuous species renewal. If the island gets bigger, species richness increases. If the island is closer to the mainland, species richness increases.The model has been criticized for its predictions and assumptions. What actually happens in nature might differ from the assumptions.
Target effect: The immigration rate not only depends on the distance of the island to the continent but also on the size of the island. Bigger islands are easier to see than smaller islands. Rescue effect: The Extinction rate not only depends on the size of the island but also the distance. Closer islands have higher chances of being colonized than the farther ones. Not all species have the same chances of getting to the islands because species vary in their dispersion capabilities. The theory does not consider in situ evolution.However, despite the critics, the theory has significant contributions:
It is a simple model that helps to define and interpret predictive models. It considers competition and competitive exclusion → As the number of species increases, the extinction rate increases too. It applies to different habitats such as patches, corridors, natural reserves, among other island-like areas. Useful for interaction and trophic webs conservationThe theory of island biogeography does state that a larger island will tend to have a greater number of species when compared to a smaller island.
An island is regarded as an ecosystem that is uniquely different from the surrounding area.
It is also stated that when immigration rates and extinction rates are at the same point or the same, the island is in an equilibrium state.
This therefore implies that the number of species on the island stays roughly the same. but, even though the number of species does not change, the composition of those species on the island may be altered.

Why are different units of measurement used for distances in space?
Light year and parasecond are some of the units which are used to measure the distance in space.
What are the distance unit?
Since space is so vast, many astronomers prefer not to measure distances in miles or kilometers. Instead, we employ a unit of measurement known as a parsec. a method used by astronomers to describe spatial distances.
A parsec is equal to 30,86 trillion, kilometers. The nearest star, Alpha Centauri, comes to mind. It is 41,560,000,000,000 (or 41.56 trillion) kilometers away, or 1.347 parsecs.
Although a 1,400-year-old statement in the Koran relating it to the revolutions of the moon around the Earth is true.
Therefore, Light year and parasecond are some of the units which are used to measure the distance in space.

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.
