Answer:
<u>a food web</u>
Explanation:
What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.
In this example, we observe there are <u>seven</u> organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.
The green algae are Producers (because it produces its own food, not dependant on others)
The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)
The other organisms are Consumers. (because they are dependant on others for their nutrition).
A) A flap in the heart located between each atrium and ventricle.
Hope it helps! :)
A way to measure plant growth. The issue with an experiment like this, is there is no way of telling if the plant would have grown differently if you had not added the extra fertilizers. To properly test this you must have "control" plants that would grow in the same conditions just without any fertilizer. You have to have multiple plants as subjects to get a good amount of data and then take the averages of each fertilizer and compare them that way.
(Just as a headsup if you are going to do this as a science fair project, don't use raw egg or unprocessed chicken poop. The egg turns the soil into rock and the chicken feces smells horrible and starts to mold. >< )
Answer:
Explanation but if im wrong correct me
Answer: The spellings are wrong. It should be globulin and heme.
Globulin alone is not effective as oxygen carrier because globulin does not have oxygen binding groupband cannot bind oxygen.
Heme alone is not effective as oxygen carrier because the iron present in heme can be oxidized easily and it cannot bind to oxygen.
Explanation:
Globulin are proteins that are present in the blood of humans. It is an oxygen carrier.
Heme is iron containining compound that form the non protein part of haemoglobin and other biological molecules. Heme are responsible for carrying oxygen in the blood.
