Answer:
parasitism
Explanation:
In evolutionary ecology, parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.

The color that the new generation's offspring show will be red, pink, and white.
The young creation of living things is called an offspring, which can be created by a single organism or, in the event of sexual reproduction, by two organisms. A group of offspring is sometimes referred to as a brood or progeny in a more generic sense.
All of the pink-flowered progeny are produced when a red-flowered plant and a white-flowered plant are crossed. This cross serves as an example of the incomplete dominance of red and white. The mixing of both alleles results in this circumstance. Gene interaction known as incomplete dominance occurs when only one of two alleles of a gene at a locus is fully expressed, frequently leading to an intermediate or distinct phenotype. Additionally called partial dominance.
CRCW × CRCW = CRCR, CRCW, CWCW i.e, red, pink, and white.
The complete question is:
A red carnation is crossed with a white carnation: Neither one is 3 Fonts dominate over the other: This means that when crossed, their offspring can show pink flower The parent generation genotypes are: CR CR and CW CW (RED x WHITE) An offspring showing pink flowers (CR CW) from the parent generation is now being bred with another pink flower (CR CW) What color will this new generation's offspring show?

Answer:
The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.
Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.
The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs. The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.
In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.
This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.
It’s true. Stems are organs that hold the trees and plants up and also produces the leaves and secondary stems
