The best answer to fill in the blank is "multilayered membrane."
Answer: The infrared radiations can detect the coolest and dimmest space objects.
In general, the coolest and darkest regions of space emit radiations of longer wavelengths. The Infrared telescope is used to find the cool, dim stars by slicing the interstellar dust bands and also measure the temperature of the planet of the solar system. The coldest stars do not emit light so they can be seen with the infrared telescopes only. In the visible region, blue stars are hottest and red are the coolest. The wavelength is inversely proportional to the energy emitted so the hottest stars are in the region of low wavelength in visible region.
The right answer is Nutrients and water.
All unicellular organisms such as bacteria and fungi need water, a source of energy, a source of carbon, a source of nitrogen and mineral elements. These basic needs are sufficient to allow the nutrition of bacteria qualified as prototrophs. Some bacteria called auxotrophs require, in addition to basic needs, the presence of growth factors.
answer: It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA. This 'unzipping' of the molecules will expose the nitrogenous bases of the nucleic acid chain so that new nucleotides can be added to create the daughter strand.
