Scientists have been studying the size of three populations in Peru. In this ecosystem, pumas (large wild cats) eat deer, and deer eat grass. The data showed that all three populations were stable. Then the puma population increased suddenly. What will most likely happen to the size of the deer population as a result?
Answer:
hen the puma population in an ecosystem increases suddenly, it is likely to have an impact on the size of the deer population.
Here's what might happen to the deer population as a result:
1. Increased predation: With more pumas in the ecosystem, there will be a higher number of predators hunting deer. This means that the pumas will be consuming more deer than before, leading to a decrease in the size of the deer population.
2. Competition for resources: As the puma population grows, there might be increased competition between pumas and deer for resources such as food and shelter. This competition could further impact the deer population by limiting their access to essential resources and potentially reducing their population size.
3. Altered behavior of deer: Due to the increased presence of pumas, deer may alter their behavior to avoid predation. They might change their feeding patterns, become more vigilant, or avoid certain areas. These behavioral changes could have indirect effects on the deer population, possibly leading to changes in their distribution and population size.
4. Cascade effects: The changes in the deer population can also have indirect effects on other organisms in the ecosystem. For example, a decrease in the deer population could lead to an increase in the availability of grass, which may then affect other herbivores or plants in the ecosystem. These cascade effects can further influence the overall dynamics of the ecosystem.
It's important to note that while these are potential outcomes, the actual impact on the deer population would depend on various factors such as the rate of puma population increase, availability of alternative prey, and the resilience of the deer population to predation pressure. Studying such interactions in ecosystems helps scientists understand the complex dynamics that shape populations and maintain ecological Balance

A) absorb more oxygen with each breath
B) release less carbon dioxide with each breath
C) experience an increase in blood pH
D) experience a “burning” sensation in the muscles
Answer:
D: experience a “burning” sensation in the muscles
Explanation: Based on the information in the lesson, this option makes the most sense.
"When lactate builds up, the blood’s pH drops and the muscles fatigue. This is why you may feel your muscles "burn" from the buildup of lactic acid."
In the given scenario, the jogger will experience a “burning” sensation in the muscles. The correct option is D.
What is muscle fatigue?Muscle fatigue is the loss of a muscle's capacity to create force. It can be caused by strenuous exercise, but abnormal fatigue can also be caused by impediments to or interference with the various stages of muscle contraction.
When lactate levels rise, the pH of the blood falls and the muscles fatigue. That's why individuals may feel their muscles "burn" as lactic acid builds up.
Thus, the correct option is D.

simple diffusion and facilitated diffusion are both types of _____ transport.
Simple and facilitated diffusion are both types of passive transport.
Both facilitated and simple diffusion are modes of passive transport. They transport substances from areas of high concentration to areas of low concentration. However, the former differs from the latter in the way molecules are transported across the membrane. Follow a concentration gradient (high to low) without ATP.
There are three main types of passive transport:
Simple diffusion – movement of small or lipophilic molecules (e.g. O2, CO2, etc.) Water molecule movement is referred to as osmosis (dependent on solute concentrations) Diffusion is the movement of big or charged molecules through membrane proteins (e.g. ions, sucrose, etc.)
Passive transport is the fundamental movement of ions and other molecular substances in cells along concentration gradients without external energy. Also called passive diffusion.

Explanation:
kevin is dreaming that he is running away from a tiger. fortunately, his ____________________ system prevents him from kicking and moving while he is dreaming.
Kevin is dreaming that he is running away from a tiger. Fortunately, his brain's built-in safety mechanism, known as the "REM atonia" or "sleep paralysis" system, prevents him from kicking and moving while he is dreaming.
This system is activated during the rapid eye movement (REM) stage of sleep, when most dreaming occurs. It works by temporarily inhibiting motor neurons, which are responsible for controlling muscle movement.
The REM atonia system serves to protect the sleeper from potential injuries that could result from physically acting out their dreams. It ensures that the body remains in a state of relative paralysis, allowing the brain to process and interpret dream content without any physical interference. This protective mechanism is essential for maintaining the body's overall safety and well-being during sleep, as it allows the brain to engage in vital restorative processes while keeping the body immobilized and secure.
In rare cases, some individuals may experience a phenomenon known as REM sleep behavior disorder, in which the REM atonia system fails to function properly. This can lead to individuals physically acting out their dreams, sometimes resulting in injury to themselves or their bed partners. However, in most cases, the REM atonia system successfully keeps the body still and secure, allowing individuals like Kevin to safely dream of running away from tigers without any real-world consequences.

differentiate clearly between the roles of the pulmonary and systemic circuits
Pulmonary circulation delivers deoxygenated blood from the heart to the lungs, where it picks up oxygen and releases carbon dioxide. Systemic circulation delivers oxygenated blood from the heart to the rest of the body, where it releases oxygen and picks up carbon dioxide.
Pulmonary circulation begins when the right ventricle of the heart pumps deoxygenated blood into the pulmonary artery. The pulmonary artery branches into the right and left pulmonary arteries, which carry the blood to the lungs. In the lungs, the blood flows through a network of capillaries that surround the alveoli, which are tiny air sacs. The oxygen in the air in the alveoli diffuses into the blood, and the carbon dioxide in the blood diffuses into the air in the alveoli. The blood then flows back to the heart through the pulmonary veins, which empty into the left atrium.Systemic circulation begins when the left ventricle of the heart pumps oxygenated blood into the aorta. The aorta branches into a network of arteries that carry the blood to all parts of the body. In the tissues, the blood flows through a network of capillaries that surround the cells. The oxygen in the blood diffuses into the cells, and the carbon dioxide in the cells diffuses into the blood. The blood then flows back to the heart through a network of veins, which empty into the right atrium.The pulmonary and systemic circuits work together to deliver oxygen and nutrients to the cells and remove carbon dioxide and waste products.
