Explanation:

During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.

The diagram can be improved by:

                                  Lungs

                                       ↓

                                   oxygen

                                       ↓

                      Red blood cells (carrying oxygen)

                                       ↓

                  Organs (like stomach and liver etc) from where carbon    

                               is taken and oxygen is supplied

                                         ↓

                   RBC's carrying Carbon dioxide to the lungs

The component which is missing in the diagram are the organs where exchange of gases occurs. The red blood cells carry oxygenated blood from the lungs to all parts of the body and carries the wast carbon dioxide gas from them back to the lungs. The carbon dioxide is then exhaled by the lungs.

The principal of Dominance states that
jeka94

Principle of Dominance was given by Sir Gregor Johann Mendel.

<h3><u>Explanation:</u></h3>

Principle of Dominance was given by Sir Gregor Johann Mendel as a conclusion of the monohybrid cross between the different characteristic pea plants. It says that in an organism which is heterozygous for a particular character, only the dominant trait is able to express as a phenotype, not the recessive one. In other words, the recessive allele is completely masked by the presence of the dominant allele. This leads to same phenotype of a homozygous dominant organism and a heterozygous organism.

To test the organism about its heterozygosity, the organism is led through a test cross where the organism is crossed with a recessive organism. If the F1 offsprings are all dominant, then the organism is homozygous dominant, and if the F1 offsprings are of half dominant and half recessive phenotype, then the organism is heterozygous.

Roots that enable a plant to grow on another plant are called ________.
Luden [163]

Answer:

epiphytic roots

Explanation:

Epiphytic roots are those that live on other plants without parasitism. In this relationship, the epiphyte uses the other vegetable only as a support (phorophyte), removing no nutrients and, consequently, causing no harm to the species.

Epiphyte roots are estimated to represent about 10% of the total amount of vascular plants on the planet. This means that there are on average 29,000 plant species with this peculiar habit of life. These vegetables are mainly found in tropical rainforests and have almost no representatives in places with very low temperatures.
