there is no clear evidence about plants evolving in the desert, or fossils of any kind of cactus despite their distribution over a large area. But, scientists are of the opinion that they acquired specific attributes millions of years ago, as a response to the vastly changing climate and conditions.
-Desert plant root system
A typical desert plant has a deep root system, which is a specific physical mechanism. As the roots grow deep down the soil, they absorb soil water, which is then transported to the upper portions of the plant.
-Desert plant leaves
Bear small foliage with waxy surface to minimize transpiration (loss of water through stomatal pores), which in turn, helps to conserve water.
Im going to say that its <span>d. The head of the phospholipid, which is hydrophilic, helps to control the movement of large hydrophobic molecules, and the tails of the phospholipid, which are hydrophobic, help to control the movement of large hydrophilic moleculeus. </span>
The Van der Waal’s forces are the forces, which are formed by the attraction of two opposite charged bodies. This charge exists due to the formation of the dipoles in the molecules or atom. The dipoles formed due to the movement of the electron in the atoms. The strength of the dipole or Van der Waal attraction depends on the size of the atoms or the molecule. As the size increases, the strength of the Van der Waal force increases. The positive and the negative regions are shown in the attached picture.
When a homozygous red-eyed female was crossed with the white-eyed male (w+w+ × wY), the resulting F1 females were w+w and the F1 males were w+ Y. Crossing the F1 males and F1 females would yield these results:
<span>All the F2 females would have red eyes, although some would be homozygous (w+w+ ) and others would be heterozygous (w+w). </span>
<span>Half the F2 males would have red eyes (w+ Y), and half would have white eyes (wY).</span>
