Q. Which one of these characterizes a hydrophilic substance?
A. Substances that are polar in nature (water is polar).
Answer:
The ozone layer absorbs a large portion of incoming UV radiation, which keeps ground-level ozone from forming. A higher percentage of UV radiation entering the troposphere would allow a greater amount of ozone to form in the troposphere. Ozone is a pollutant in the troposphere. By regulating the amount of UV radiation that enters the troposphere, the ozone layer also regulates the amount of ozone formation in the troposphere.
<h2>Gametophyte and Sporophyte Generations</h2>
Explanation:
- <em>The sexual stage, called the gametophyte generation,</em> produces gametes, or <em>sex cells, and the abiogenetic stage, or sporophyte age, </em>produces spores abiogenetically
- As far as chromosomes, the <em>gametophyte is haploid</em> (has a solitary arrangement of chromosomes), and the <em>sporophyte is diploid (has a double set)</em>
- All aquatic plants have alternation of generations. In mosses and their <em>family members (Bryophytes), the haploid gametophyte is the predominant age,</em> and the diploid sporophytes are sporangium-bearing stalks developing from the gametophytes
S PHASE
<span>Cell division involves the different phases such as G1, G2, M and S phase. Cell division is the mechanism of cells to divide into other cells. Two types of cell division is popularly called the mitosis and meiosis. There basic difference is how they function and how many chromosomes their daughter cells have. </span>
