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?

Answers

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.

X-ray crystallography is a very important process that is used to help identify the structure of molecules. What exactly does this process show?

Answers

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.

why do you think Harvey placed the sea urchin cells in a hypersonic solution?​

Answers

Harvey placed the sea urchin cells in a hypersonic solution in order to see the behaviour of the cell in the hypersonic solution.

What Harvey placed the sea urchin cells in a hypersonic solution?​

In 1940 Ethel Brown Harvey evolve a technique for separating embryonic sea urchin cells. She took a pair of embryonic cells to develop from the first cell division after Harvey's fertilization. She settles the pair of cells in a hypertonic solution, carrying double the amount of salt as that contained in seawater. Most sea urchins produce a group of early embryonic cells which is known as micromeres. Small blastomeres Harvey that form by unequal cell division at the vegetal pole of the early embryo. Harvey Sub-Sea is the first that indicated Maritime Labor Convention compliant.

So we can conclude that Ethel Brown Harvey developed a technique for dividing embryonic sea urchin cells.

Answer:

d) The antigen-presenting cell encounters and processes the antigen.

e) With the antigen, the antigen-presenting cell migrates to the nearest lymph node.

b) The antigen-presenting cell displays the antigen to the T cells.

c) The T cells initiate the immune response if the antigens are viral proteins or abnormal antigens.

a) Infected or malignant cells are then destroyed before they can do further harm to the body.

Explanation:

The antigen-presenting cells (e.g., dendritic cells, macrophages) are cells of the immune system that mediate cellular immune responses by processing and presenting antigens (i.e., peptides components of pathogens) to T lymphocytes. The antigen-presenting cells travel through lymphatic vessels from the site of infection to the lymph nodes where they present antigens to naive T cells, i.e., T cells that have matured but have not yet encountered their corresponding antigens. This presentation facilitates the clonal expansion of T cells that are specific for the antigen which acquire effector functions in order to destroy infected cells. This process is known as immune clearance and is associated with the apoptosis of antigen-specific T cells.

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.

Answers

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.

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
