Why do biologists believe that a primitive choanoflagellate protist is the ancestor to all animals

Since an animal only becomes more complex, and not simpler, an ancestor to all organisms would have to be the most simple and primitive organism.

<h2>Community Residents authorties prepare for an earthquake aftermath. </h2>

If we live in an area that is susceptible to earthquakes then we should follow such suggestions like store household items in a way that won’t cause injury, make sure large items are fastened to walls. Make sure not to sleep under a window and assemble emergency kits. Also if we are inside then remain in the specific position. However if, outside then use good sense and clean up any danger spots.

Which policy would most likely decrease a city's gasoline use

Daniel [21]

Make sure the gas cap is on tight. One reason you may not be getting the mileage you expect is because there isn't as much gas in your tank as you think. 147 million gallons of gas were lost last year due to evaporation. Why did it evaporate? The gas cap was not on tight. So just make sure it is tight, and it will enable you to keep all the gas you pay for

A bat species (species 1) lives in a city. Another bat species (species 2) established a population in that same city after some

ddd [48]

Answer:

Roosting areas in buildings of any height are the resource partitioning of both bat species.

Explanation:

The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species.

The realized niche refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species.

Competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor.

Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use resources -partially or completely-, migrates or get extinguished.

A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the same habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.
