The principle of competitive exclusion states that A. two species cannot coexist in the same habitat. B. competition between two
larisa86 [58]

The principle of competitive exclusion states that two species cannot coexist in the same habitat.

<h3>What is competitive exclusion?</h3>

The competitive exclusion principle, often known as Gause's law, is a theory in ecology that holds that two species competing for the same scarce resource cannot coexist at constant population levels. One species will eventually outnumber all others if it has even a modest edge over the others. This results in the weaker competitor's extinction or an evolutionary or behavioral shift in favor of a different ecological niche. The adage "complete competitors cannot coexist" is a paraphrasing of this idea.

Although he never created it, Georgy Gause is traditionally credited with coming up with the competitive exclusion principle. The natural selection theory put forward by Charles Darwin already incorporates the concept.

The status of the principle has fluctuated during the course of its history between

How does gene expression lead to differentiation
ExtremeBDS [4]
Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.

Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Fantom [35]

Answer:

Correct

Explanation:

Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.

The Homoeostatic feedback mechanism has three basis components and they are independent to one another.

These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.

So, the order  in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.
