Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae.
Helmut Zemo (aka the 13th Baron Zemo) is Heinrich Zemo 's son, [8] born in Leipzig, Germany. Helmut was originally an engineer until he became enraged when reading a report about the return of Captain America and his father's death.

Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light.
Methyltrichlorosilane results from the direct process of chloromethane with elemental silicon in the presence of a copper catalyst, usually at a temperature of at least 250 °C. [1] 2 CH 3 Cl + Si → (CH 3) 4−n SiCl n + other products. While this reaction is the standard in industrial silicone production and is nearly identical to the first ...
Atmospheric optics. A colorful sky is often due to indirect sunlight being scattered off air molecules and particulates, like smog, soot, and cloud droplets, as shown in this photo of a sunset during the October 2007 California wildfires. Atmospheric optics is "the study of the optical characteristics of the atmosphere or products of ...
The tube is filled with a purified gas mixture, and the gas ionized by a high voltage applied between the ends of the sealed tube through cold cathodes welded onto the ends. The color of the light emitted by the tube may be just that coming from the gas, or the light from the phosphor layer. Different phosphor-coated tubing sections may be butt ...
Kepler-11e is an exoplanet (extrasolar planet) discovered in the orbit of the sunlike star Kepler-11. It is the fourth of six planets around Kepler-11 discovered by NASA 's Kepler spacecraft. Kepler-11e was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
Description. A close-up of a red-flowered poppy. Wild Poppy in Behbahan. Wild Poppy in Mazandaran. Poppies are herbaceous annual, biennial or short-lived perennial plants. Some species are monocarpic, dying after flowering. Poppies can be over a metre tall with flowers up to 15 centimetres across. Flowers of species (not cultivars) have 4 or 6 ...
