Note each of them:
Archaea is a single-celled microorganism with no nucleus
Bacteria is a unicellular microorganism with cell walls but lack organelles
Sarcodina is a phylum with temporary extensions of the cell. They can be parasitic.
Protista is an eukaryotic organisms that is not an animal, plant, or fungus.
The organism found is unicellular (rules out Archaea), with cell walls (characteristics of bacteria), and the ability to produce spores.
I believe that Bacteria (B) is your best answer
hope this helps
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.
Answer:
Explanation:
Physical and chemical digestion occur in the mouth; only chemical digestion occurs in the small intestine.
Answer:
False.
Explanation:
From biology, we can know about the definition of gymnosperms. In the description of gymnosperms, we can see that gymnosperms are those type of plants which do not produce any ovary. It is known that the ovary turns into a fruit. As gymnosperms do not have any ovary, they can't produce their seeds inside of a fruit. In the case of other plants except for gymnosperms, the seeds are produced from the developed ovules. But in the case of gymnosperms, the ovules are located directly on the exterior of the flower.
So, the statement is false.
