Nestled at the edge of the arid Great Basin and the snowy Sierra Nevada mountains in California, Mono Lake is an ancient saline lake that covers over 70 square miles and supports a unique and productive ecosystem. The lake has no fish; instead it is home to trillions of brine shrimp and alkali flies. Freshwater streams feed Mono Lake, supporting lush riparian forests of cottonwood and willow along their banks. Along the lakeshore, scenic limestone formations known as tufa towers rise from the water's surface. Millions of migratory birds visit the lake each year.
From 1941 until 1990, the Los Angeles Department of Water and Power (DWP) diverted excessive amounts of water from Mono Basin streams. Mono Lake dropped 45 vertical feet, lost half its volume, and doubled in salinity.
The Mono Lake Committee, founded in 1978, led the fight to save the lake with cooperative solutions. We continue our protection, restoration, and education efforts today with the support of 16,000 members --and we host this Website.
In 1994, after over a decade of litigation, the California State Water Resources Control Board ordered DWP to allow Mono Lake to rise to a healthy level of 6,392 feet above sea level--twenty feet above its historic low. It is rising toward that goal -- click here for the current lake level, or visit one of the other links on this page for more of the Mono Lake story.
Answer:
Life cycle of a moss
Explanation:
LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE
An embryo further develops into a pear-shaped sporangium, which is the *sporophyte stage of the plant*. The sporangium contains spore sacs, each of which is the spore mother cell that undergoes meiotic division to form four spores,The spores are released and germination
takes place giving rise to a protonema, which develops into a new gametophyte plant. The gametophyte generation or haploid phase of the moss is from the production of haploid spores after meiosis to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid phase is from the diploid mother cells just before meiosis.
Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.
The myelin sheath (C) insulates the axons.
The myelin sheath is a fatty substance, hence why it is great for insulation. <span />
He was studying genetics by performing mating crosses in pea plants. Then, he discovered that the traits in the offspring didn't always match the traits in the parental plants.
