The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.
The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.
The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.
Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.
Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).

How does this happen? During interphase, how does a cell prepare for division? Describe cell division, including the processes of mitosis and cytokinesis. Be sure to describe the mitotic steps. Question 3) Mitosis and meiosis are similar processes, but they have some very important differences. Explain how mitosis and meiosis are alike and how they are different. Provide at least two similarities and three differences. ( Please Do Not Repost Someone Else's Answer that is on Brainly Or Any Other Websites) Will Mark Brainliest .
Explanation:
Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.

Write a paragraph explaining how adhesion, cohesion and capillary action all enable water to go from the roots to the top of a tall tree.
Answer:
Capillary action helps bring water up into the roots. But capillary action can only "pull" water up a small distance, after which it cannot overcome gravity. To get water up to all the branches and leaves, the forces of adhesion and cohesion go to work in the plant's xylem to move water to the furthest leaf.
Explanation:
Hope This Helps!
Water is moved up through the plant by capillary action from the soil.
Hydrogen connections between water molecules give them a sticky property that allows them to form droplets. Droplets can stick to the plant because of adhesion.
what is capillary action?Capillary action is the movement of liquid along a solid's surface induced by the attraction of the liquid's molecules to the solid's molecules.
The movement of a liquid across the surface of a solid induced by adhesion between the two is known as capillary action.
The higher the water climbs on its own, the narrower the tube becomes. Water is forced up the columns of cells in the xylem and through fine tubes in the cell wall by adhesion in plants.
The transport of water through the plant is known as capillary action. When the adhesion is stronger than the cohesion, this movement happens. The attraction between water molecules is natural. The transient hydrogen bonds that they form are the source of their attraction.
what is adhesion and cohesion?The act of attaching one thing to another is known as adhesion. Water adheres to the organic tissues of plants thanks to adhesion.
Cohesion is the property that allows molecules of the same substance to stick together.
Water molecules are held together by cohesion in plants. Intermolecular attraction leads liquids to create a top or outer layer that acts like a thin film.
The shape of water drops is determined by surface tension, which also holds structures together as they absorb water.

Courtship may be rather simple, involving a small number of chemical, visual, or auditory stimuli; or it may be a highly complex series of acts by two or more individuals, using several modes of communication.It help strengthen a pair bond that may last through the raising of the young or even longer.Courtship is its use as an isolating mechanism, a method of keeping different species from interbreeding.

Answer:
The organic compounds in coal are composed of the elements carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a variety of other elements
Coal is a mixture of organic compounds and minerals formed from ancient plant material, primarily composed of carbon, hydrogen, and impurities like sulfur and nitrogen.
Coal is a mixture of organic compounds and minerals, resulting from the decomposition of ancient plant material over millions of years. It primarily consists of carbon, hydrogen, oxygen, nitrogen, and sulfur. Carbon, the dominant organic compound, makes up a substantial part of coal's composition, with hydrogen and oxygen occurring in lesser amounts.
Nitrogen and sulfur are present as impurities, in the form of organic compounds and mineral components. Coal also contains inorganic minerals like quartz, clay, and pyrite, contributing to its ash content. Trace elements, such as mercury, arsenic, and lead, are present in low concentrations. The exact composition varies based on coal type and location, influencing its energy content and environmental impacts.

Entre los siguientes métodos de separación de mezclas, Jorge debe seleccionar el adecuado para separar sal de una mezcla de sal y agua, en la que la sal se encuentra completamente disuelta.
50%
Teniendo en cuenta la composición de la mezcla, ¿cuál de los anteriores métodos debe usar Jorge para separar la sal?
Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
Evaporación, porque este método únicamente se usa para separar líquidos.
Filtración, porque la sal y el agua se mezclan muy bien.
Filtración, porque la sal es blanca y el agua transparente.
Teniendo en cuenta las definición de evaporación, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
El método de separación utilizado para el agua y la sal es: la evaporación.
La evaporación consiste en pasar el soluto disuelto en un liquido a estado gaseoso y ocurre al aumentar su temperatura de forma natural o artificial,. Dependiendo de que se desea evaporar se utiliza el material correspondiente. La técnica mas común es por contacto y puede acelerarse si utilizamos un material conductor dentro del liquido.
En otras palabras, se conoce que la evaporación es el proceso por el cual las distintas moléculas en estado líquido, como lo es en agua, pasan a un estado gaseoso de manera espontánea, siendo este el principal efecto de la evaporación.
Como se mencionó el método de separación utilizado para el agua y la sal es la evaporación. Durante este proceso, al aplicar calor, el agua se convierte en vapor y se libera al aire. La sal, como tiene otro punto de ebullición, no se evapora.
Entonces, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
