which of the following statements is/are correct about the cortisol pathway? question 1 options: a. cortisol is secreted by cells in the adrenal medulla b. cells of the anterior pituitary gland express cortisol receptors (i.e., glucocorticoid receptors) c. a decrease in cortisol causes a decrease in acth. d. (a) and (b) are correct; (c) is incorrect e. (a), (b), and (c) are all correct

Answers

Answer 1

The correct statement about the cortisol pathway is: (c) a decrease in cortisol causes a decrease in ACTH.

Cortisol is secreted by cells in the adrenal cortex, not the adrenal medulla as stated in option (a). Cells of the anterior pituitary gland express cortisol receptors (glucocorticoid receptors) which are involved in negative feedback control of the hypothalamic-pituitary-adrenal (HPA) axis, where cortisol exerts its effects by suppressing the release of corticotropin-releasing hormone (CRH) and adrenocorticotropic hormone (ACTH). Therefore, option (b) is correct.

Option (c) is also correct because a decrease in cortisol levels would lead to a decrease in negative feedback on the HPA axis, resulting in increased release of ACTH. Hence, the correct option is (c).

which is not a significant cause of the current mass extinction event? invasive species overharvesting habitat destruction extreme weather events

Answers

Invasive species is not a significant cause of the current mass extinction event.

Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction. Determining this point is challenging because a species' potential range may be quite wide, and is typically done after the fact. Due to this problem, there are phenomena like Lazarus taxa, in which a species that was thought to be extinct suddenly "reappears" after a period of apparent absence (usually in the fossil record).

how does the intestinal mucosa prevent the development of food allergies mounted against innocuous food antigens? group of answer choices it has several tolerogenic (aka immunosuppressive) mechanisms that inhibit immune activation to non-infectious material there are no adaptive immune cells (t or b cells) in the intestine no antibodies can cross the intestinal epithelium to initiate complement signaling all food antigens are broken down into individual atoms before reaching the intestine

Answers

There are no adaptive immune cells (t or b cells) in the intestine .

In general, the epithelial cells transport antibodies, particularly IgA, into the intestinal lumen and these specialized antibodies helps to contribute and act as a barrier by excluding the uptake of antigens or microbes.

So, in order to prevent a food allergy reaction it is required to completely avoid the food and any product that may contain any such ingredient. Intolerant Food never trigger the immune system and also not considered life threatening, although it may cause similar symptoms like diarrhea and stomach pain.

once a potato is placed in a more and more hypotonic solution it gains less and less weight. this is called turgor pressure. explain what is happening with respect to the water molecules and cell walls of the plant?

Answers

Once a potato is placed in a more and more hypotonic solution, it gains less and less weight because the amount of solute inside the potato is moved into the solution to reach equilibrium.

A hypotonic solution is a kind of solution which has lower solute concentration than the one being compared with, here potato. As per the query, potato is placed in a hypotonic solution. This means that the potato has a larger solute concentration than this hypotonic solution. Now, both the concentrations would try to reach equilibrium in both of their, solute and solvent, aspects. Thus, the potato becomes lighter as the amount of its solute is moved into the solution.

This happens as follows: water molecules cluster around solutes, pushing them away, allowing more water molecules to enter the region of concentration. As a result, adding a hypotonic solution to a hypertonic solution will cause the mixture to experience highs and lows in concentration at first before quickly coming to equilibrium.

What is genetics?

The study of genes and heredity, or how particular characteristics or traits are passed from parents to offspring as a result of changes in DNA sequence, is known as genetics. A gene is a section of DNA that has the instructions needed to create one or more molecules that support bodily function. A double helix, or corkscrew-shaped ladder, is how DNA is shaped. The bases are pairs of the four building blocks adenine, thymine, guanine, and cytosine, and the two ladder rails are referred to as the backbones. The instructions for constructing molecules, the majority of which are proteins, are included in the sequences of these nucleotides. According to researchers, there are around 20,000 genes in humans.

Answer:

Fenotipos de la F1: 50% de la progenie muestra orejas medianas y lana blanca, mientras que el otro 50% muestra orejas medianas y lana negra. En este caso en particular, el cuadro de Punnett no es necesario pero resulta de gran utilidad para visualizar la cruza.

Explanation:

Datos disponibles:

El color de la lana sigue una herencia dominante para el color blancoEsta especie puede tener las orejas cortas, medianas o largasCruza: carnero de lana negra y orejas largas X oveja de lana blanca y orejas cortasProgenie: al menos un ejemplar con lana negra

Podemos suponer que para el gen determinante del color de lana, el alelo dominante L determina lana blanca, mientas que el alelo recesivo l determina lana negra. También podemos suponer que para el gen que determina la longitud de las orejas, el genotipo LL expresa orejas largas, el genotipo Ll expresa orejas medianas, y ll expresa orejas cortas por tratarse de herencia intermedia. Entonces:

B--> Lana Blanca

b --> Lana Negra

LL --> Orejas largas

Ll --> Orejas medianas

ll --> Orejas cortas

Cruza: carnero de lana negra y orejas largas X oveja de lana blanca y orejas cortas

Puesto que en la progenie habia por lo menos un ejemplar con lana de color negro, podemos suponer que la oveja era heterozigota para la caracterítica en cuestión, ya que es la única forma de obtener un genotipo recesivo en la F1.

Parentales) bb LL x Bb ll

Gametos) bL, bL, bL, bL Bl, bl, Bl, bl

Cuadro de Punnet) Bl bl Bl bl

bL BbLl bbLl BbLl bbLl

F1) Genotipo: 8/16 BbLl

8/16 bbLl

Fenotipo: 8/16 o 50% animales de lana blanca

8/16 o 50% animales de lana negra

16/16 o 100% animales de orejas medianas

Posiblemente no sea necesario utilizar un cuadro de Punnet con la cruza mencionada. Sabiendo los genotipos paterno y materno es posible determinar las proporciones fenotipicas de la F1 sin realizar el cuadro de Punnet.

Para longitud de orejas se puede deducir que todos los ejemplares en la F1 serian heterocigotos, expresando orejas medianas. Esto se debe a que la cruza ocurre entre un homocigota dominante y un homocigota recesivo para esta característica.En tanto que para la caracteristica del color de lana se podria asumir que la mitad sería blanca y la otra mitad negra, puesto que la cruza es entre un homocigota recesivo y un heterocigota.

Aun así, mientras haya pocos genes dialélicos involucrados en la cruza, el uso del cuadro de Punnet siempre resulta útil para una mejor visualización de la cruza.

These tasks encompass promoting nutritious schooling, helping rural improvement, and supplying clean water and sanitation.

Actions to enhance employee well-being and make the organization a tremendous vicinity to work: Nestlé invests in worker well-being through numerous programs, including health and well-being tasks, schooling and improvement opportunities, paintings-life stability projects, and employee aid packages.

Actions to defend and maintain the environment: Nestlé has set environmental sustainability dreams and has implemented measures to lessen its environmental impact. The organization makes a specialty of areas which include water and strength efficiency, waste control, sustainable sourcing, and climate change mitigation.

Based on these additives, Nestlé's method appears to be socially accountable as the corporation takes movements throughout numerous dimensions of CSR. However, it is essential to be aware that assessing an enterprise's typical social responsibility involves a more complete analysis, such as evaluating the effectiveness and impact of these moves, as well as thinking about any criticisms or controversies surrounding the organization's practices.
