Answer:
<u>Option-(C,A):</u>Archaea must undergo meiosis prior to cell division, and Each chromosome in a polyploid organism has distinct genetic information.
Explanation:
- <u> Archaea are polyploid:</u>
Archea are prehistoric organisms who can be also termed as the prokaryotic living cells, as they developed from a less developed form to a more complex shape or system. As the feature of being a polyploid makes it easy for any archea to survive in the most severe conditions. As the polyploids contain a number of genetic materials in pair, as each pair is very distinctive in features or more independent in regulating a function then the other. Giving it a more diversity of genetic sequence its genome.
Along, with that the process of meiosis occurs prior to the process or event of cell division. Which is for production of the copies of the parent cell, which posses the same genetic material as that of the parent cells.
Answer: Soil moisture and fertility
Cheat grass is likely to decrease the soil moisture of the region, thus rendering the soil infertile and unfit for other plants growth.
Explanation:
Cheatgrass is an exotic weed native to Europe, West Asia and Northern Africa. Cheatgrasses outcompeted native vegetation as a result of large number of livestocks like cattle and sheep into sagebrush region. The livestocks overgrazed on native vegetation, which resulted to a void filled rapidly by Cheatgrass.
Cheatgrass grows on pastures, hills, and ranges. Wildfires promote more Cheatgrass but destroy native plants vegetation. Cheatgrass can survive drought due to deep root system they possess. The deep root system make the plant to grow and flourish with even small amount of water. Its deep root system reduce soil moisture and deplete soil fertility, preventing the growth of other plants. Also, Cheatgrass is self germinating and require les soil to grow. All these attributes that favor Cheatgrass have threatened native plants such as sagebrush plants and woodlands.

Scientific laws explain phenomena that have been proven to be true by the scientific community. In general, theories explain how a phenomenon occurs, whereas laws predict what will happen in a particular scenario based on an equation.
A scientific law foretells the outcomes of particular initial circumstances. It may tell you what color hair your unborn child would have or how far a baseball will travel when launched at a specific angle. In contrast, a theory seeks to offer the most plausible justification for why events take place the way they do.
The five most well-known scientific laws are:
- Bernoulli's law of fluid dynamics.
- Dalton's law of partial pressures.
- Hooke's law of elasticity.
- Fourier's law of heat conduction.
- Archimedes' Principle of Buoyancy.
