Answer: Antidiuretic hormone binds to receptors on cells in the collecting ducts of the kidney and promotes reabsorption of water back into the circulation. ... These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.

Answer:

<em>Chargaff: </em>The work of Erwin Chargaff has major contributions towards understanding of DNA structure as a double helix. Although, he didn't propose the DNA as a double helix, but he was the first scientist two establish two rules that lead to the discovery of DNA as a double helix. Briefly, he proposed that (1) in any DNA, the amount of Guanine are always equal to the amount of Cytosine and likewise, the amount of Adenine are always equal to the amount of Thymine; and (2) the amount of guanine, cytosine, adenine and thymine bases are different in each species. This observation supported the idea later that DNA is the heriditary material rather than proteins.

<em>Franklin</em><em>:</em> Rosalind E. Franklin is known for her work on understanding the molecular structure of DNA via X-Ray diffraction. For that, she exposed crystallized DNA moleculeto X-rays and some of the rays were deflected back thus forming a diffraction pattern. She was the first scientist that produces real images of DNA explaining its molecular structure. As an example, I have attached the Photo 51 she took while working at King's College London. Her work led to the actual discovery of DNA as a double helix (Watson and Crick Model) which we know today.

<em>Watson and Crick</em>: James Watson and Francis Crick proposed the 3D structure and model of the DNA helix which we know as of today. Precisely, their work explained that DNA is a double-stranded, antiparallel, right-handed helix. Further, the nitrogenous basis proposed earlier (A, T, G, C) are attached to sugar-phosphate backbone via hydrogen bonds. It is one of the major discoveries in molecular biology.

What are electromagnetic waves that you can see?
Nataliya [291]
<span><span>Radio waves: If our eyes could see radio waves, we could (in theory) watch TV programs just by staring at the sky! Well not really, but it's a nice idea. Typical size: 30cm–500m. Radio waves cover a huge band of frequencies, and their wavelengths vary from tens of centimeters for high-frequency waves to hundreds of meters (the length of an athletics track) for lower-frequency ones. That's simply because any electromagnetic wave longer than a microwave is called a radio wave.</span><span>Microwaves: Obviously used for cooking in microwave ovens, but also for transmitting information in radar equipment. Microwaves are like short-wavelength radio waves. Typical size: 15cm (the length of a pencil).</span><span>Infrared: Just beyond the reddest light we can see, with a slightly shorter frequency, there's a kind of invisible "hot light" called infrared. Although we can't see it, we can feel it warming our skin when it hits our face—it's what we think of as radiated heat. If, like rattlesnakes, we could see infrared radiation, it would be a bit like having night-vision lenses built into our heads. Typical size: 0.01mm (the length of a cell).</span><span>Visible light: The light we can actually see is just a tiny slice in the middle of the spectrum.</span><span>Ultraviolet: This is a kind of blue-ish light just beyond the highest-frequency violet light our eyes can detect. The Sun transmits powerful ultraviolet radiation that we can't see: that's why you can get sunburned even when you're swimming in the sea or on cloudy days—and why sunscreen is so important. Typical size: 500 nanometers (the width of a typical bacteria).</span><span>X rays: A very useful type of high-energy wave widely used in medicine and security. Find out more in our main article on X rays. Typical size: 0.1 nanometers (the width of an atom).</span><span>Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are a type of harmful radiation. Typical size: 0.000001 nanometers (the width of an atomic nucleus).</span></span>

Which of the following statements about energy is TRUE? Question 17 options: It can be used over and over again. It tends to be
Law Incorporation [45]
<h2>Energy </h2>

Explanation:

Energy flows in only one direction through an ecosystem

  • The Sun supports most of Earth's ecosystems
  • Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
  • The food energy created by producers is passed to consumers, scavengers, and decomposers
  • Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
  • Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
  • So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
  • Animals at the third level have only 10% as much available to them as those at the second level
