Answer:

phospholipids, sterols, and triglycerides

Phospholipids make up the outermost layer of cells in the bodies of both animals and humans. They create a protective layer around the cells to help maintain them.

Sterols are a subset of steroids, a type of hormone.

Triglycerides are the fats and oils that you are familiar with in foods. This type of lipid can be saturated or unsaturated, which is part of what makes them solid or liquid, respectively, at room temperature.

neonofarm [45]

The correct answer is - b. The owl and the robin have more characteristics in common.

All three animals are in fact connected, but the connections are very different. While the owl and the robin are closely related, their connection with the bat can be traced few hundred million years ago. The owl and the robin are both birds, they share common ancestors in the early transitional species of bird-like dinosaurs, and before that their ancestors were part of the dinosaurs. The bat on the other hand, is a mammal, and has evolved from the primitive shrew like mammals that got an open space after the dinosaurs disappeared, and while living along side them were living in their shadow. So the bat's connection to the owl and the robin is going much further into the geologic past, before the diversification of the species to mammals and reptiles.

Answer:

Explanation:

1)Pfr/Pr

2) Pr

3)far-red

Explanation:

The leaves at the top of a tree’s canopy are exposed to direct sunlight during the day, and their phytochromes will occur in a high *Pfr/Pr* ratio. Meanwhile, the leaves of the same tree at the bottom of the canopy are highly shaded during the day and will likely have a higher proportion of the * ( PHYTOCHROME )Pr *;form of phytochrome present due to exposure to a higher proportion of *FAR RED * light.

Plants make use of the phytochrome system to it's adjust growth based on the seasons. Through phytochrome plants is able to respond to the timing and duration of dark and light periods. At dawn, all the phytochrome molecules present in the leaved are converted to the active Pfr form until sunset this is because the sun is unfiltered, and unfiltered sunlight has high percentage of red light, but lower far-red light, with the help of phytochrome system , the plants is able to compare the length of dark periods over several days.
