An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 600 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably "Lithocarpus" (stone oaks), as well as in those of unrelated species such as "Grevillea robusta" (silky oaks) and the Casuarinaceae (she-oaks). The genus "Quercus" is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaf with smooth margins. Also, the acorns contain tannic acid, as do the leaves, which helps to guard from fungi and insects. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 618 months to mature, depending on their species. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus. What are the answers to this following set of questions: 1.

(CNN) -- The Royal Canadian Mounted Police said authorities Friday took a fourth person into custody in their ongoing investigation into domestic terrorism.

The RCMP said its Integrated National Security Enforcement Team executed a search warrant in Ottawa and took one person into custody. No charges have been filed.

Earlier Friday, a Canadian government source close to the investigation said the three men arrested previously "are not card-carrying members of al Qaeda but they follow in the movement and show common trends."

RCMP Chief Superintendent Serge Therriault said Thursday the three suspects are Canadian citizens living in Ontario -- Hiva Mohammad Alizadeh, 30, of Ottawa; Misbahuddin Ahmed, 26, of Ottawa; and Khurram Syed Sher, 28, of London.

The name of the suspect arrested Friday has not been released.

Alizadeh faces three charges: conspiracy, committing an act for a terrorist group and providing or making available property for terrorist purposes. Canadian federal prosecutor David McKercher told CNN the three charges carry maximum sentences ranging from ten years to life in prison.

Ahmed has been charged with conspiracy, but he could face more charges, according to his defense attorney. Ian Carter told CNN he met with Ahmed for half an hour. Asked how the suspect was feeling, Carter said, "He is in shock." Ahmed is married and has a 7-month-old daughter.

Sher also is charged with conspiracy, officials said.

The RCMP said the three suspects were arrested under Canada's Anti-Terrorism Act, passed in 2001.

Therriault said that a yearlong investigation found that in addition to forming part of a terror cell, the suspects possessed schematics, videos, drawings, instructions, books and electrical components designed specifically for the construction of improvised explosive devices. He said authorities seized more than 50 circuit boards designed to remotely detonate IEDs. What are the answers to this following set of questions: 1. Where was the search carried out?

Greg enjoys playing with his friends. On Friday, Greg went outside to play with two of his friends, Peter and Lucy. They played with a ball for some time, but then they got bored. Lucy said that she wanted to climb a tree. Peter thought that they could see if their other friend Robert could play with them.

The three of them went to find Robert. They saw Robert in front of his house, but he said that he was busy and he could not play with them. Greg and Peter then thought that Lucy's idea was good. There was a large tree in the park. Greg, Peter, and Lucy walked to the park together.

When they got to the park, they were surprised by the size of the tree. It was much larger than they thought. At first, Greg was scared to climb the tree. But Peter and Lucy told him that it would be fun, so he began to climb. When he had climbed the first few branches, he slipped and fell down. But he was not hurt. After that, the three friends thought that it was too dangerous to climb that tree. So they all went home.
