Energy decreases as it moves up tropic levels because energy is lost as metabolic
The correct answer is Operant Conditioning.
Operant Conditioning refers to the process of gaining knowledge of system via which the power of a behavior is modified by using reinforcement or punishment. it's also a method that is used to bring about such learning.
even though operant and classical conditioning both contain behaviors managed by environmental stimuli, they range in nature. In operant conditioning, stimuli present when a behavior is rewarded or punished come to govern that conduct.
To attain spherical shape is the hydro-static equilibrium have on a solar system body
<u>Explanation:</u>
The interior of the sun has hydrostatic equilibrium which keeps the sun stable. It helps to maintain equilibrium between the gravitational force and the force exerted due to the gas. The gravitational pull creates inward force to destabilise the sun. But the gases creates outward pressure.
These two forces acting against each other give a spheroidal shape for the planets.The static structure of the solar system body is obtained by the hydrostatic equilibrium and not giving room to shrink or expand its state.
Answer:
convergent evolution
Explanation:
If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.
Answer:
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success.
Explanation:
The Darwinian evolutionary theory was created by Charles Darwin.
Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact.
