Answer:
In biology, a cladogram can be described as a diagram which shows evolutionary relationships among different organisms. A cladogram shows which organisms share evolutionary history and which organisms are more closely related to one another.
<em>The cladogram in the above picture shows that the limbs originated after the jaws. </em>
The cladogram shows that amoeba was a common ancestor to sponges, earthworms, salmon, lizards, kangroo and cats.
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.
The words for the descriptions are food chain, trophic level, energy pyramid, high diversity, low diversity, etc. respectively.
<h3>Ecology</h3>
- The feeding relationship that exists among organisms is termed the food chain.
- Each step in the transfer of energy and matter in a community is termed the trophic level.
- A community or group of living organisms that live in and interact with each other in a specific environment is termed an ecosystem.
- A diagram that compares the energy used by producers, primary consumers, and other trophic levels is known as the energy pyramid.
- An ecosystem with a high number of species is said to be of high diversity.
- An ecosystem with a few prominent species and a low number of other species is said to be of low diversity.
- Organisms that feed on and break down organic matter are said to be decomposers.
- Organisms that can make their own food in the ecosystem are termed, producers.
- Animals that feed on flesh are called carnivores.
- A system of interlocking and interdependent food chains is called a food web.

Answer:
The reason why toxic chemicals are classified as hazard because they can do as much damage as hazard things and can cause a serious of problems to one's health, for something to be hazard it can be flammable, and toxic chemicals are just that.
