Dinosaur fossils had been known for centuries as "dragon bones" or the remains of giants, but it wasn't until Dean William Buckland of Oxford, England described the carnivorous "lizard" Megalosaurus<span> (in 1824) that they were formally studied as an extinct group of giant reptiles</span>
The pituitary gland, or hypophysis, is an <span>endocrine gland that consists of anterior pituitary (or adenohypophysis) and posterior pituitary (or neurohypophysis). Adenohypophysis regulates several physiological processes (including stress, growth, reproduction, and lactation) by secreting hormones. The neurohypophysis functionally connects the gland to the </span>hypothalamus. The intermediate lobe (between adeno and neurohypophysis) synthesizes and secretes melanocyte-stimulating hormone. Because it controls a lot of functions inside the organism it can affect many things when it is not working properly (over- or under-production of pituitary hormones). It can cause diabetes insipidus by a deficiency of vasopressin, it can cause thyroid disorders, gigantism (too much growth hormone)…
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical chemical energy that can later be released to fuel the organisms activities.
Semi-conservative DNA replication means that one stand is new DNA and the other contains a newly synthesized strand.
