Evolutionary<span> thought, the conception that </span>species<span> change over time, has roots in antiquity - in the ideas of the </span>ancient Greeks<span>, </span>Romans<span>, and </span>Chinese<span> as well as in </span>medieval Islamic science<span>. With the beginnings of modern </span>biological taxonomy<span> in the late 17th century, two opposed ideas influenced </span>Western<span> biological thinking: </span>essentialism<span>, the belief that every species has essential characteristics that are unalterable, a concept which had developed from </span>medieval Aristotelian metaphysics<span>, and that fit well with </span>natural theology<span>; and the development of the new anti-Aristotelian approach to </span>modern science<span>: as the </span>Enlightenment<span> progressed, evolutionary </span>cosmology<span> and the </span>mechanical philosophy<span> spread from the </span>physical sciences<span> to </span>natural history<span>. </span>Naturalists<span> began to focus on the variability of species; the emergence of </span>paleontology<span> with the concept of </span>extinction<span> further undermined static views of </span>nature<span>. In the early 19th century </span>Jean-Baptiste Lamarck<span> (1744 – 1829) proposed his </span>theory<span> of the </span>transmutation of species<span>, the first fully formed theory of </span>evolution<span>.</span>
An endothermic reactions involves absorption in which energy is on the reactant side of the question or the left side. Exothermic involves the release of energy in which energy is on the product side of the equation.
A child presents with bone deficiency and a bowlegged appearance. This assessment data supports a diagnosis of:
a) Rickets
b) Osteoporosis
c) Osteomalacia
d) Paget disease
Answer:
a) Rickets
Explanation:
Rickets occurs at the early stage of childhood due to inadequate vitamin D.
Vitamin D provides the body with higher absorption rate of calcium and phosphorus, inadequate intake of Vitamin D results into low calcium and phosphorus levels in the bones, as a result, rickets sets in.
Rickets is a disarrangement of impaired mineralization of cartilaginous growth plates in children. It can also result from lack of exposure to sunlight.
Answer:
Solar Radiation
Explanation:
Increased carbon dioxide in the atmosphere leads to increased absorption of Solar Radiation.
Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.
