Plant reproduction is the production of new individuals or offspring in plants, which can be accomplished by sexual or asexual means. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from the parent or parents. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur. In seed plants, the offspring can be packaged in a protective seed, which is used as an agent of dispersal.
Aerospace engineering is the primary branch of engineering concerned with the research, design, development, construction, testing, science and technology of aircraft and spacecraft. It is divided into two major and overlapping branches: aeronautical engineering and astronautical engineering. The former deals with aircraft that operate in Earth's atmosphere, and the latter with spacecraft that operate outside it.
Aerospace engineering deals with the design, construction, and study of the science behind the forces and physical properties of aircraft, rockets, flying craft, and spacecraft. The field also covers their aerodynamic characteristics and behaviors, airfoil, control surfaces, lift, drag, and other properties.
The Ruby-throated Hummingbird (Archilochus colubris) is a species of hummingbird.
The Bee Hummingbird or Zunzuncito (Mellisuga helenae) is a species of hummingbird that is endemic to dense forests and woodland edges on the main island of Cuba and (formerly) on the Isla de la Juventud, also part of the nation of Cuba. With a mass of approximately 1.6–2 g (0.056–0.071 oz) and a length of 5–6 cm (2.0–2.4 in), it is the smallest living bird.
The male has the green pileum and fiery red throat, iridescent gorget with elongated lateral plumes, bluish upper-parts, and the rest of the underparts mostly greyish white. The male is smaller than the female. The female is green above, whitish below with white tips to the outer tail feathers. Compared to other small hummingbirds, which often have a slender appearance, the Bee Hummingbird looks rounded and chunky.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
