An example of natural selection is the red color of a male cardinal. the females of the species choose mates based on the vibrant colors of the males’ feathers. if females begin using different criteria than feather color when they choose mates, what would most likely happen to the tails of peacocks over time? increased variation in the shades of red because the selection pressure has been relieved increased variation in the shades of red because the cardinals try different ways to impress the females decreased variation in the shades of red because no form of the trait is advantageous decreased variation in the shades of red because the only reason for variation was selection pressure

decreased variation in the shades of red because no form of the trait is advantageous

Explanation:

The red color of a male cardinal is there to attract the female cardinal.

If the female cardinals device another means to selecting their mates, then the male cardinals shall have no use of the red shade.

Therefore variations in the red shade shall decrease due to disuse.

The male cardinals shall adapt to the new method of selection.

Decreased variation in the shades of red because no form of the trait is advantageous.

Explanation:

Natural selection may be defined as the differential reproduction and survival of the individual due to their differences in the phenotype. Natural selection acts as the main driving force for evolution.

The male cardinal red color gets change or may show variation as it is no longer used by them to attract the females. The red shade variation get decreases and may get changed over time. The red color trait is non advantageous and get extinct with time.

Thus, the correct answer is option (3).

the major parts of the digestive system:

salivary glands.

pharynx.

esophagus.

stomach.

small intestine.

large intestine.

rectum.

accessory digestive organs: liver, gallbladder, pancreas.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
