X-ray crystallography is a very important process that is used to help identify the structure of molecules. What exactly does this process show?
Answer:
can reveal the precise three-dimensional positions of most atoms in a protein molecule because x-rays and covalent bonds have similar wavelength, and therefore currently provides the best visualization of protein structure.
Because x-rays and covalent bonds have comparable wavelengths, they can now give the finest imaging of protein structure because they can reveal the precise three-dimensional locations of the majority of atoms in a protein molecule.
What is X-ray crystallography?
X-ray, a scientific technique called crystallography may be used to map out the atoms of a crystalline material in three dimensions. By using most crystalline materials' interatomic gap as a diffraction gradient for x-ray radiation, which has wavelengths on the order of 1 angstrom, this method makes use of the interatomic spacing of most crystalline solids.
Wilhelm Rontgen made the discovery of x-rays in 1895. Up until 1912, there remained disagreement about whether x-rays constituted electromagnetic energy or particles. Researchers recognized that this light's wavelength would need to be in the range of 1 Angstrom (A) if the wave theory was accurate.
It would be necessary to use a gradient with separation on the same order of magnitude as the light for diffraction and measurement of such tiny wavelengths.
To diffract the x-ray beams, the arrangement of the atoms must be in an ordered, periodic form. The specific arrangement of atoms in that crystal is then revealed through a sequence of mathematical computations to create a diffraction pattern. The principal technique still in use today for studying the structure and bonding of organometallic compounds is X-ray crystallography.
Therefore, since x-rays and covalent bonds can display the precise three-dimensional locations of the majority of atoms in a protein molecule, they provide the best imaging of protein structure currently achievable.

What is the albedo effect?
Do you think the earth is warming up?
Answer: Astronomers define the reflectivity of an object in space using a term called albedo. This is the amount of electromagnetic radiation that reflects away, compared to the amount that gets absorbed.
Explanation: But to answer the "Earth warming up" question, I'd have to say that for over millions of years, Earth's climate has warmed up and cooled down many times. However, today the planet is warming much faster than it has over human history. Global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century. However, other evidence suggests that the period of 2,000 to 3,000 million years ago was generally colder and more glaciated than the last 500 million years.
So, yes I do believe that the Earth is warming up but not to explode.

The answer to this question
Answer:
- Spores occur underneath the leaves - PTERIDOPHYTES
- cones contain the seeds - GYMNOSPERMS
- absorbs nutrients through diffusion and osmosis - BRYOPHYTES
- ovary encases the seeds - ANGIOSPERMS
Explanation:
Plants are a very diverse group of living organisms. Each plant group has its own unique characteristics that distinguishes it from other groups. Bryophytes and pteridophytes are considered as lower plants because of their primitive features while gymnosperms and angiosperms are considered as higher plants because of their advanced features. The prominent characteristics of each plant group according to this question is as follows:
- PTERIDOPHYTES produce spores underneath their leaves.
- BRYOPHYTES absorbs nutrients through diffusion and osmosis since they lack true roots, stems and vascular tissues.
- GYMNOSPERMS bear their naked seeds on structures called cones or strobili.
- ANGIOSPERMS encases their seeds in ovaries of their flowers, which later develops into fruits.
name a disorder that is a result of shortage of proteins in children
Answer:
A disorder that is a result of shortage of proteins in children is Kwashiorkor
Explanation:
Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)
Hopefully this helps.
Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.
Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.
Other terms for kwashiorkor include:
protein malnutrition
malignant malnutrition
protein-calorie malnutrition

Explanation:
La polidactilia en la especie humana se debe a un alelo dominante. Entre Francisco y Martha, ambos abuelos de Santiago, uno de ellos tenía polidactilia, sin embargo Juan su hijo (papá de Santiago) nació normal. A pesar de ello Santiago es polidactílico. La explicación a esta situación es que
Respuestas:
A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.
B) Como uno de los abuelos era aa (homocigoto recesivo-normal) y el otro Aa (heterocigoto-polidactílico), Juan nació probablemente aa (homocigoto recesivo-normal) y por ello no hay manera que Santiago naciera polidactílico.
C) Como uno de los abuelos era aa (homocigoto recesivo-normal), Juan nació probablemente aa (homocigoto recesivo- normal) y por ello Santiago es polidactílico.
D) Como Francisco y Martha eran Aa (ambos heterocigotos-polidactílicos), Juan nació probablemente AA (homocigoto dominante- polidactílico) y por ello Santiago es polidactílico.
Answer:
A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.
Explanation:
La polidactilia es una malformación causada por un alelo dominante asociada con al aparición de más de 5 dedos en cada pie o más de 5 dedos cada mano. Un alelo dominante es una variante génica capaz de enmascarar la expresión de un alelo recesivo en individuos heterocigotos, es decir, en individuos portadores de una copia del alelo dominante y una copia del alelo recesivo para un gen en particular. De este modo, un alelo dominante es por definición aquel que será expresado en el fenotipo, con lo cual el único modo en el cual Santiago sea portador del alelo dominante causante del rasgo "polidactilia" es que él lo haya heredado, ya sea del padre o de la madre (es importante aclarar que también el alelo dominante puede haber surgido por mutación en la línea germinal). En este caso sabemos de acuerdo al enunciado que el padre de Santiago no tiene polidactilia y por lo tanto no es portador del alelo dominante, con lo cual se espera que Santiago haya heredado esta condición de su madre.

You have a beautiful garden at home. On Sunday, you start budding your rose plant to make few more samples of rose plants to plant in the garden. Can you categorize how this scenario could be represented by classes and instances?
Answer:
It is possible to make this categorization as follows:
Roses = Class
Rose samples = instances
Explanation:
In a very direct and objective way, we can state that classes are models that define how a given situation will be handled, which methods will be used to manage it and the objectives that will be established in that situation. Instances, on the other hand, are elements taken from the interior of classes, which contain factors that make them up. Based on this, we can determine that, in the case of the above question, roses are classes and rose samples are instances.
