Answer: After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.
Explanation:
Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.
An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
The parasite can live<span> in the environment for many months and contaminate soil, water, fruits and vegetables, sandboxes, grass where animals graze for food, litter boxes, or any place where an infected cat may have defecated. </span>Toxoplasmosis<span> is an infection caused by a microscopic parasite called </span>Toxoplasma<span> gondii.</span>
Answer:
D
Explanation:
There are many food chains within a food web, so D seems like the best possible answer :)
Directly
Explanation:
The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy.
Whales play an important role in stabilizing the aquatic food chain and reproduction of other species.
As more whales are killed the food distribution in the ocean becomes destabilized and causes changes in the food supply of many other kinds of marine life.
Whales are vital to the food chain, stabilising food flow and maintaining a healthy ocean.
As such, the rapidly decreasing whale population will have major effects on the ocean's ecosystem.
Believe it or not, whale poop also serves quite an important purpose to the ecosystem.
