Ground squirrels are found in many areas of the United States. They live in underground burrows and are often attacked by birds of prey, coyotes, and bobcats. Which of the following is a limiting factor for a ground squirrel population? a population of tree squirrels a population of hawks genetic variability breeding season
Answer:
a population of hawks
Explanation:
hawks are predators and feed on small ground/tree animals, such as squirrels, rabbits. rats,
The number of ground squirrels may be constrained by the presence of predators including bobcats, coyotes, and birds of prey.
What will be the impact of predators in the population?These predators pressure may lead to fewer individuals in the population, which may alter the distribution of those individuals within the environment. Food and water availability are examples of resources that may be limited.
For instance, the number of ground squirrels will be constrained if it increases too much and there is not enough food to feed it. The number of ground squirrels may also be impacted by environmental factors such as temperature, precipitation, and habitat accessibility.
Limiting factors are those that prevent a population from expanding. Predators like birds of prey, coyotes, and bobcats are limiting variables in the case of ground squirrels since they can reduce the squirrel population. Competition for resources like food, water, and shelter may be another limiting issue.
Therefore, the number of ground squirrels may be constrained by the presence of predators.

a. A hunch
b. The unifying theory of evolution
c. Experimentation
d. The scientific method
e. Observations of green sea turtles' behavior
Answer:
Option b
Explanation:
Hypotheses are carried out as proposed explanation made on the basis of limited evidence which serves as a beginning point for further study.
The biologist in this case has a limited evidence with regards to this species which is just only about its ancestry, so her hypothesis was based on the unifying theory of evolution which is the framework within which biologists ask questions about the living world providing predictions with regards to directions about living things.
The correct answer, unequivocally, is (B).

Estimate how many arteries branch off the aorta given that arteries have a diameter of 0.4 cm and a flow speed of 45 cm/s.
Answer:
Approximately 25 arteries would branch off
Explanation:
Aorta has a diameter of 2 cm, so area is pi x 1^2 = 3.142
In case of the artery, pi x 0.2^2 = 0.126
So dividing total area of aorta by total area of one artery, we get 3.142/0.126 = 25.021
Hence, about 25 arteries will be needed to carry the amount of blood that flows in the aorta vessel.

I am generally found both inside and outside of the nucleus in a eukaryotic cell! DNA RNA BOTH?
RNA is found outside of the nucleus wile DNA is found inside the nucleus.
Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Both the inner and outer membranes of the nuclear envelope are phospholipid bilayers. The nuclear envelope is punctuated with pores that control the passage of ions, molecules, and RNA between the nucleoplasm and cytoplasm.In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane.In eukaryotes, the cell's genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.Learn more:

In the case of two EPSPs occurring at a single synapse, which of the following will produce a subthreshold effect and not generate an action potential on the postsynaptic neuron’s axon hillock?
a. Both EPSPs occurring in rapid succession
b. The summed EPSPs depolarizing the axon hillock membrane to —70 mV
c. Both EPSPs occurring before the postsynaptic membrane potential returns to —55 mV
d. Both potentials occurring after the postsynaptic membrane potential returns to its resting value
Answer:
Both potentials occurring after the postsynaptic membrane potential returns to its resting value
Explanation:
This is simply because, a neuron returning to its resting state,will have the ligand gated Na+ channels closed.Therefore depolarization can not occur.More K+ gated channels will open, and more K+ leaks out of the axoplasm,returning the neuron to the resting state.
Hence if the summation of the two EPSP returns to the resting level after crossing the synapse, they can not propagate,and generate action potential, because they will produce a sub threshold effects,which will not generate action potential.

e. Sympathetic neurons. Efferent neurons
f. Arterioles. Target
g. Ventricles. Target
h. Change in blood pressure - Stimulus
i. Medullary cardiovascular centres. Integrating center
Explanation:
The efferent parasympathetic pathway is considered to be part of the autonomic nervous system. The efferent parasympathetic control is produced by nerve signals that are transported from the central nervous system to their corresponding targets.
Targets are those tissues where nerve impulses are directed. These targets include the vascular system (i.e., arterioles, ventricles, veins, etc).
Receptors are specialized cells capable of detecting a stimulus and promote a response (i.e., an electrical impulse).
The integrating center of the nervous system is represented by the central nervous system (CNS). The CNS is composed by the brain and the spinal cord, it senses the stimulus and produces the corresponding nerve impulse (i.e., response).
