Elements such as The lungs exchange gas to maintain homeostasis. In the alveoli of the lungs, oxygen and carbon dioxide are exchanged. This exchange occurs between the lungs and blood vessels (capillaries). The transport of oxygen to the blood does not require energy. The membranes of the alveoli are thin and moist and allow gasses to dissolve and be transported to and from the blood. When we breathe, a high concentration of oxygen enters the lungs and moves to the blood. Based on this scenario, is the transport of oxygen a result of osmosis, diffusion, or active transport?
Answers
Answer:
oxygen are among the few simple molecules that can cross the cell membrane by diffusion. And Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
Explanation:
Answer:
This is Diffusion........... :)

A carbon footprint is a measure of the amount of carbon human activities, like using energy, release into the atmosphere. Which activity would help decrease the greatest carbon-releasing activity in US homes? limiting time in hot showers wearing layers of clothing turning off lights when leaving a room unplugging electronics when not in use
Answers
Answer: unplugging electronics when not in use
Explanation:
Carbon footprint is the measure of the amount of carbon liberated into the atmosphere due to human oriented activities like burning of fossil fuels, deforestation, liberation of toxic gases including carbon monoxide and carbon dioxide into the atmosphere by the factors and automobile vehicles. To stop the carbon releasing activity in US homes one must unplug the electronic not in use because electronics consume a lot of electrical energy every day this electrical energy comes from thermal power plants which typically use coal to harness energy the combustion of the coal liberates carbon dioxide and carbon monoxide in the environment so creating pollution and increases the carbon footprint. Little will be the usage of electricity little will be the burning of coal and it will decrease the carbon footprint.

Answers
Answer:
To find out the impact of environment on the physical structure of lizard and natural selection.
Explanation:
Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

In 1989, a tanker carrying oil struck a reef and spilled 11 million gallons of oil in an
Alaskan bay. The oil not only spilled into the harbor, but also washed up on the
shoreline. The spill killed millions of fish, birds that lived on the shore, sea otters,
porpoises, seal lions and many whales. Every form of life in the area was affected.
Scientists have carefully studied the area and its species since the initial spill to
determine both short-term and long-term effects.
Which of the following was affected the least by this catastrophic event? A: Plants along the shoreline B: Fishermen in the area C: Migratory sea birds D: Crustaceans that lived on the bottom of the bay
Answers
Answer:
The answer is C: Migratory sea birds.
Explanation:
Sea birds that are migrating would not only just fly above the spill and nestle on the trees, but they could eat crabs and other animals that scurry around on the shore as a food source due to the death of their primary source of food, fish.

what triggers angry in the brain?
Answers
Answer:
amygdala
Explanation:
Answer:
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression. Epinephrine or adrenalin released by medulla of the adrenal glands, surges at the time of panic and emergency. It provokes stress response and brings out the arousal of extreme emotions like fear, anger or amusement.
