Answer:
- plant mass related to H2O
- conclusions partly correct
Explanation:
The randomness in the alignment of recombined chromosomes at the metaphase plate, coupled with the crossing over events between nonsister chromatids, are responsible for much of the genetic variation in the offspring. To clarify this further, remember that the homologous chromosomes of a sexually reproducing organism are originally inherited as two separate sets, one from each parent. Using humans as an example, one set of 23 chromosomes is present in the egg donated by the mother. The father provides the other set of 23 chromosomes in the sperm that fertilizes the egg. Every cell of the multicellular offspring has copies of the original two sets of homologous chromosomes. In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate. Because there is an equal chance that a microtubule fiber will encounter a maternally or paternally inherited chromosome, the arrangement of the tetrads at the metaphase plate is random. Thus, any maternally inherited chromosome may face either pole. Likewise, any paternally inherited chromosome may also face either pole. The orientation of each tetrad is independent of the orientation of the other 22 tetrads.
Explanation:
Leaves change color due to changes in length of daylight and changes in temperatures, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.

There are choices for this question namely:
a. cementation of clastic sediments and precipitates from seawater
<span>b. compaction and recrystallization of volcanic material </span>
<span>c. regional metamorphism of sedimentary and igneous rocks </span>
<span>d. contact metamorphism of unconsolidated gravel
</span>
The correct answer is that the bedrock of the Adirondock mountains is formed mainly by regional metamorphism of sedimentary and igneous rocks. The geology of the Adirondock mountains formed around 5 million years ago with rocks over 1000 million years old. At this very ancient age, the sedimentary and igneous rocks in the Adirondock mountains have undergone extensive heat and pressure hence regional metamorphism of the existing sedimentary and igneous rocks.
