Answer: B. Increased surface runoff has increased water pollutants.
Explanation:
Trees provide a very valuable service in limiting the effects of surface runoff such as the reduction of soil erosion on account of trees holding the soil together with their roots. Their presence also reduces the actual surface runoff because they impede the path of the water.
With deforestation getting rid of trees, they would be unable to anchor the soil and reduce the movement of water which means that surface runoff will increase.

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.
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 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.

Which of the following statements about classical conditioning is false?
A. The strength of conditioning depends on extent of coincidence of conditioned and unconditioned stimuli.
B. In Pavlov’s paradigm where a sound becomes able to elicit salivation, the sound is the conditioned stimulus.
C. In Pavlov’s paradigm where a sound becomes able to elicit salivation, the sound is unconditioned stimulus.
D. Hebb synapses have properties that could explain the changes required for the establishment of conditioning.
It is false that C. In Pavlov’s paradigm where a sound becomes able to elicit salivation, the sound is unconditioned stimulus.
Classical conditioning refers to a learning type where an animal or human reacts to a stimulus without thinking because they have been trained/ conditioned to do so.
There are two types of stimuli:
Conditioned stimulus Unconditioned stimulusAn unconditioned stimulus refers to a type of stimulus that a person would normally react to in a certain way for instance:
Smell of food making you hungry Seeing a snake making you scaredA Conditioned stimulus is not natural but rather results from you having associated a stimulus with an event so many times that you react to that stimulus in a certain way:
Sound making a dog hungry so much so that it salivates You becoming happy when you see your mother come home from work because she usually brings treats.In conclusion, we can say that a sound causing an animal to salivate is not unconditioned but rather conditioned because it is not natural to react to sound in that way.

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.

You will find the map in the attached files
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.
