Banana plantsBanana plants growing on a plantation. Each herbaceous trunk bears only one bunch of fruit and is cut down after harvest to encourage new growth from the rhizome (underground stem)
The banana plant is a gigantic herb that springs from an underground stem, or rhizome, to form a false trunk 3–6 metres (10–20 feet) high. This trunk is composed of the basal portions of leaf sheaths and is crowned with a rosette of 10 to 20 oblong to elliptic leaves that sometimes attain a length of 3–3.5 metres (10–11.5 feet) and a breadth of 65 cm (26 inches). A large flower spike, carrying numerous yellowish flowers protected by large purple-red bracts, emerges at the top of the false trunk and bends downward to become bunches of 50 to 150 individual fruits, or fingers. The individual fruits, or bananas, are grouped in clusters, or hands, of 10 to 20. After a plant has fruited, it is cut down to the ground, because each trunk produces only one bunch of fruit. The dead trunk is replaced by others in the form of suckers, or shoots, which arise from the rhizome at roughly six-month intervals. The life of a single rhizome thus continues for many years, and the weaker suckers that it sends up through the soil are periodically pruned, while the stronger ones are allowed to grow into fruit-producing plants.

The Book of Why: The New Science of Cause and Effect [Paperback] Pearl, Judea and Mackenzie, Dana
Correlation does not imply causation.' This mantra was invoked by scientists for decades in order to avoid taking positions as to whether one thing caused another, such as smoking and cancer and carbon dioxide and global warming. But today, that taboo is dead. The causal revolution, sparked by world-renowned computer scientist Judea Pearl and his colleagues, has cut through a century of confusion and placed cause and effect on a firm scientific basis. Now, Pearl and Science journalist Dana Mackenzie explain causal thinking to General readers for the first time, showing how it allows us to explore the world that is and the worlds that could have been. It is the essence of human and artificial intelligence. And just as pearl's discoveries have enabled machines to think better, the book of why explains how we can think better.
One of the most important abilities of a MGO is being curious – to ask those questions (and keep asking them) that get to the deeper set of answers that will reveal the key drivers of the caseload donor.
A basic lesson in marine biology as it applies to the aquarium hobby goes as follows: if you stock a tank with males and females of the same species, chances are they’ll mate and reproduce at some point, often during the spring, and the female will lay dozens of eggs for insemination. In some cases, fish are live-bearers and “mouthbrooders,” like the African cichlids in the picture. Some species will breed at a prolific pace that keeps fish keepers on their toes, so you’ll have to make certain decisions in this regard. Keeping only males or only females of the same species is recommended if you don’t want to deal with breeding. Otherwise, here are five tips you can follow when your fish reproduce.
Most fish species rest on the bottom whilst in their sleep phase and appear for all intents and purposes to be in a daydream-like state. Some even lie on their sides, like this peacock wrasse

Pelagic fishing on the Great Barrier Reef is an exhilarating experience. These awesome fish inhabit the open ocean - including species like Tuna, Marlin, Spanish Mackerel and Mahi-mahi - and are an absolute challenge to catch.
The idea of taking a relaxing afternoon to cast your line and catch some fish is deeply engrained in our culture as a staple past time, and for good reason.
