Answer:

I belive it is the urinary system

Explanation:

My reasoning is because you have 2 pairs of kidneys which filter excess water, and waste called urea from blood and urine. Connecting to the kidneys are ureter tubes, which come in pairs. I'm not sure if this helps, but I tried lol.

Helga [31]

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.

Answer: The basic theme of whale evolution is the development of large animals from much smaller ancestors, and nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way.
