Answer:
Cycads /ˈsaɪkædz/ are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, therefore the individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly[3] and live very long, with some specimens known to be as much as 1,000 years old.[citation needed] Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group.
Cycads are gymnosperms (naked seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobili), somewhat similar to conifer cones.
Cycads have been reported to fix nitrogen in association with various cyanobacteria living in the roots (the "coralloid" roots).[4] These photosynthetic bacteria produce a neurotoxin called BMAA that is found in the seeds of cycads. This neurotoxin may enter a human food chain as the cycad seeds may be eaten directly as a source of flour by humans or by wild or feral animals such as bats, and humans may eat these animals. It is hypothesized that this is a source of some neurological diseases in humans.[5][6]
Cycads all over the world are in decline, with four species on the brink of extinction and seven species having fewer than 100 plants left in the wild.[7] The plant has a very long fossil history, with evidence that they existed in greater abundance and in greater diversity before the Jurassic and late Triassic mass extinction events.

Answer: Option A
Explanation:
The hypothyroidism can be defined as the condition in which the thyroid hormone is not able to produce thyroid hormones.
The thyroid stimulating hormone is produced by the pituitary gland. This hormone functions by regulating the production of the hormones by the thyroid gland.
If there is an unusual amount of the hormones released by the pituitary gland there will be an abnormal amount of the TSH and TRH. The thyroid stimulating hormones cannot respond to the hormone released from the pituitary.
Hence, the correct answer is Option A.
<span>For the answer to the question above, the nurse must remove victim's clothing and have them wash thoroughly.
The nurse should've victim's shower and change clothes and irrigate or wash open wounds with soap and water. Cleansing the skin helps to reduce the transition from external to the internal radiologic contamination. Infectious micro-organisms are not involved, so chlorhexidine is of no particular benefit. Applying PPE over contaminated clothing could make the risk of injury worst. Good ventilation is very important, also the removal of contaminants is the priority because of the increased risk of injury.</span>

Explanation:
The words energy and force are not interchangeable - they are not the same as each other. A force is a push or a pull which is easily demonstrated and felt but energy is a slightly more abstract concept. They are measured in different units: force in Newton's and energy in Joules.
