Answer:

Explanation:

A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface. The armpit of a human and a warm freshwater mud puddle are a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them

Nitrogen-fixing bacteria carry out the conversion of gaseous nitrogen to a biologically useful form of nitrogen
An energy pyramid illustrates that energy in the form of heat is lost to the surroundings as it is passed from one organism to the next
The energy role of a grizzly bear is that of a consumer because it cannot make its own food
Decomposers cycle nutrients from dead organisms back to the soil, where it becomes available for plants
The Savanna biome is characterized by its lack of trees, warm temperatures, and moderate rainfall

Explanation:

The nitrogen-fixing bacteria like Azotobacter which lives in symbiotic relationship in the rhizomes of leguminous plants. They convert inorganic atmospheric nitrogen gas through the action of its enzymes like nitrogenase to organic nitrogen in the form of ammonia, which is readily assimilated by the plants.
In an ecosystem, at each tropic level of an energy pyramid, only 10% of energy is utilized and transferred to the next higher tropic level whereas the majority of energy is dissipated as heat during various metabolic processes.
Decomposers also called saprophytes like earthworms, bacteria, fungi survives on dead and decayed remains of plants and animals and also on fertilizers, pesticides etc in the soil. They recycle the nutrients by breaking down the complex biomolecules into simpler forms and release back into the soil.
Grizzly bears being omnivores eat both plants and animals according to their availability. Hence they are both primary and secondary consumers.
Savanna is a grassland biome with a typical tropical wet and dry climate and receives moderate rainfall. Hence it cannot support trees but only have grasses.

The last common ancestor of all animals was probably a ________. A. unicellular chytrid B. multicellular algae C. multicellular

Sati [7]

Option (D) flagellated protist is correct.

The last common ancestor of all animals was probably a flagellated protist.

<h3>What is a Protist?</h3>

Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist.
The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.

Protozoa is another name for protists that resemble animals. Some are parasites as well.
The four phyla that make up the Protozoa are flagellates, ciliates, spore-forming protists, and protists that resemble amoebas.

Nuclear membranes surround the DNA of protists.
Most protists are motile, or able to move, and many of them inhabit aquatic settings.
Protists can reproduce sexually and/or asexually, and their life cycles are intricate.
Protists consume, absorb, or produce food through photosynthesis.

The United States' __________ was patterned after Germany's autobahn.

lianna [129]

The answer is D. Interstate Highway System. The United States envisioned a highway system that would allow for controlled access to the road with no stop lights and a higher speed limit. This would allow for a faster means of transportation for goods and people throughout the country. In modeling this highway system, the United States looked to the autobahn in Germany after seeing how successful it was.
