Describe the exchange of co2 and o2 the lungs
Explanation:
Co2 and O2 in the lungs are exchanged when alveoli send oxygen to the capillaries surrounding them to the nearby blood vessels which contain c02, and osmosis occurs where o2 is now in the vessels while co2 is now in the alveoli and therefore the lungs, and then the co2 is expelled out of the lungs.

The maximum number of years a human can live is called:.
Lifespan is an indicator that measures the average of the maximum number of years a human can live.
What is lifespan?It is the number of years that a newborn can live according to the standard of mortality by age of the population of its country.
In other words, it is a concept that only makes sense for one generation and is obtained as part of a mortality table that refers to the average number of years that a person is expected to live after birth.
Therefore, we can conclude that lifespan is an indicator that measures the average of the maximum number of years a human can live.

Which organism would be MOST sensitive to acid rain?
A) bass
B) clams
C frogs
D) mayflies
Answer:
Explanation:
The correct answer is option B- Clams
It is very clear how acid rain is affecting our ecosystem. Plants, animals and other living organisms are effected including their habitat.
When acid rain enters soil, it leaches aluminium from soil particles and mixes it with soil. Aluminium level in water intoxicates the water content which is critical for the survival of water animals.
The critical PH level for clams is 6.

When an animal eats, food stays in the stomach for a period of time. When a unicellular organism, such as paramecium, takes in food, the food is contained in which organelle?.
When a unicellular organism, such as a paramecium, takes in food, the food is contained in a specialized organelle called the "food vacuole." The food vacuole is a membrane-bound sac within the cytoplasm of the unicellular organism.
Phagocytosis is the process by which the unicellular organism surrounds and engulfs solid particles, such as food particles or other microorganisms, forming a food vacuole. It forms by engulfing and enclosing the food particles during the process of phagocytosis, which is a type of endocytosis.
Once the food vacuole is formed, it fuses with lysosomes (organelles containing digestive enzymes) to digest the ingested food and break it down into smaller molecules. These smaller molecules are then used for various cellular processes, including energy production and growth, within the unicellular organism.
