Answer:
trees because they change,birds they change
Explanation:
Answer:
Hypersensitivity is also known as intolerance which is defines as an unwanted reactions due to changes or interference with immune system for example allergies and autoimmunity. Hypersensitivity is the reaction of immune system that can be harmful and weakens once body.
Allergy is kind of hypersensitive reaction which is having fast response within few minutes rather than hours or days. In the case of allergies free antigens cross link with IgE on mast cells and basophils and releases vasoactive biomolecules. Few example of Allergies are anaphylaxis and asthma.
Autoimmune disorders are also a kind of hypersensitive reaction which occurs when body's immune system attacks own body cells mistakenly. few examples are Type 1 diabetes, Rheumatoid arthritis (RA), and Multiple sclerosis.
Answer:
Differentiation of heterochromatin and euchromatin decreases
Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.
<h3>
What are skeletal traits?</h3>
- The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
- Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
- Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
- We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

Answer:
The correct answer is - option A is continuous variation that follows a geographic continuum.
Explanation:
A cline is a slow change in the physical and genetic traits of a population or species across a geographical difference or gradient. If a species present in a very large area, there would be some members live on different environmental condition in comparison to others.
By this gradient members of species show continuous variation that follows a geographic continuum. For, example, In a species of warm-blooded animals have large body size in cooler area than in warmer area.
Thus, the correct answer is - option A is continuous variation that follows a geographic continuum.
