Bestway cartridges filter out grime and dirt from the water in a Lay-Z spa hot tub. They prevent this dirt from getting in to the heater and pump, which could cause damage.
Adult horses lie down during REM sleep, and sometimes they also lie down during the day to rest or sun bathe. Young foals commonly sleep lying down. Horses only lie down for short periods because they are adapted to sleep on their feet and awake quickly to flee predators.
Birds lay eggs, although there are other egg-laying animals, including two mammals: the duckbill platypus and the echidna. These two creatures are natives of Australia. Scientists call these primitive egg-laying mammals monotremes.
Some fish species are oviparous, meaning that the fish fry (babies) are born from eggs that are excreted from the female fish's body prior to hatching. Fish eggs are occasionally used by humans for food and fish bait.
Ducks do lay eggs. Eggs laid together in one batch are referred to as a "clutch." Female ducks lay anywhere from eight to 16 eggs in a clutch, with nine being the average.
Bats are mammals, not birds, so they do not lay eggs. The female bat becomes pregnant after mating with a male, just as with any other mammal.
Around 40 percent of the more than 400 species of sharks lay eggs. These eggs may develop fully or partially in the mother, or they may be laid by the mother.
Rabbits do not lay eggs, but rather give live birth. Pregnancy in rabbits lasts 31 days, with a female rabbit, known as a doe, giving birth to up to 12 babies at one time and possessing the capability to get pregnant again just a few days later.
A lay pastor, or a lay minister, is someone who is not ordained but who tends to a Christian community for little or no money. This type of ministry is usually associated with non-Episcopal churches. Lay pastors do not have the same training or education as ordained ministers.
Like most arachnids, spiders lay eggs when reproducing their young. When the female is ready to lay her eggs, she may lay as many as 1,500 at a time, although the number depends on the size and species of spider. Generally, spiders lay as many eggs as they can because few will survive to maturity.
