The answer should be d, they are in domain eukarya so their cells are eukaryotic.
Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte
Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)
Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition
Mitosis-both (mitosis occurres in spores)
Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Answer:
The separate systemic and the pulmonary conditions all evolve in the species that are having the high pressure circulatory system required for rapid movement of blood because if pulmonary was under pressure as high as that of the system circulation.
Explanation:
Here, it is given that the separate systemic and the pulmonary circulations evolve in the species.
And those species have the high pressure circulatory system for blood movement rapidly because if the pulmonary was under pressure as high as that of systemic circulation.
Also the fluid amount that will flow would be forced out of the cappilaries in the lungs.
Now, there is a conflict between the thin surface required for efficient exchange of gases.
Also, the thick blood vessels are required to withstand the high blood pressures.
