There would be more hawks appearing because there is more food (both lizards and rabbits) and grass would lessen because there is another source feeding off of it.

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.

About the question:
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.

Explain the difference between inter-cooperation and intra-cooperation between species.
Answers
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 a accurate depiction of primary ecological succession?
Answers
Answer:
This question lacks options, however, primary succession will be explained for detailed comprehension.
Explanation:
Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.
Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.

Explanation:
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.
Answers
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.
