Enhancer I can stimulate the transcription of gene A, but the insulator blocks its effect on gene B Enhancer ll can stimulate th

e transcription of gene B, but the insulator blocks its effect on gene A What would be the effect of moving the insulator to a position between enhancer Il and the promoter for gene B? Insulator-binding protein Promoter Transcription start site Transcription start site O O O O The newly positioned insulator prevents enhancer Il from stimulating the transcription of gene B. The newly positioned insulator allows enhancer Il to hyperactivate gene B transcription. The new positioning of the insulator prevents gene A expression. The newly positioned insulator allows enhancer I to activate gene B transcription.

Mashcka [7]

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

<h3>Day of deep-sea fishing</h3>

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.

Which of the following statements is true of soluble fibers? a. They are not viscous. b. They retain their tough texture after b
mamaluj [8]

Answer:

The answer is "Option C".

Explanation:

The soluble fiber was fiber and in the diet which is prescribed to increase metabolism, reduce cardiovascular problems, cure constipation, and is ideal for patient diabetes.

  • This consumes food water and provides support with gel-like characteristics, which are rich in fiber in foods like rice, fruits, and bovines.  
  • They all are essential for fitness, digestion, and preventive medicine. It draws in liquid(water) while absorption and transforms into a gel. It slows it down the digestive cycle.

Which of the following is a source of energy made from plant and animal remains?
bixtya [17]
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

These are sometimes known instead as mineral fuels.

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.

A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

¿ Cuales son los sistemas que intevienen en el proceso de nutricion? ¿ Que funcion cumple cada uno de ellos en ese proceso?
Papessa [141]

Answer:

digestivo, respiratorio, circulatorio y excretor

Explanation:

El proceso de nutrición consiste en la ingesta de alimentos, los cuales son posteriormente transformados en energía y estructuras celulares que el organismo necesita para funcionar normalmente. Durante este proceso, intervienen cuatro sistemas:

- Sistema digestivo: descompone químicamente los alimentos en nutrientes. Los alimentos son sometidos a un proceso de fragmentación mecánica y digestión química. En primer lugar, los alimentos son triturados en la boca por los dientes, mezclados con saliva para formar un bolo alimenticio que llega al estómago donde los jugos gástricos los transforman en una papilla conocida como quimo. A continuación, los nutrientes llegan al intestino delgado donde son mezclados con el jugo pancreático y la bilis del hígado para ser absorbidos por la sangre. Finalmente, los compuestos que no fueron absorbidos llegan al intestino grueso donde se absorbe lo que queda de agua y lo demás es eliminado.

- Sistema respiratorio: los pulmones son los órganos encargado del proceso de respiración mediante el cual el organismo intercambia gases con el ambiente a través la sangre. De este modo el organismo obtiene oxígeno que es utilizado para oxidar los nutrientes obtenidos por el sistema digestivo.

- Sistema circulatorio: encargado de transportar nutrientes y oxígeno a las células del cuerpo y simultáneamente transportar elementos de desecho hasta los órganos del sistema excretor.

- Sistema excretor: encargado de eliminar los desechos de los alimentos. Los compuestos que no fueron digeridos en el intestino delgado llegan al intestino grueso donde se transforman en las heces las cuales son expulsadas por el ano. Por otra parte, el aparato urinario formado por los riñones y la vejiga urinaria funcionan para eliminar los desechos de la sangre a través de la orina.

What is the percentage of calories were absorbed by your system??? Helpppp
denpristay [2]
Calories in and of themselves aren't a reliable way of describing energy density in food. It doesn't reflect what actually happens in your body (look up bomb-calorimeter for how people figure out calorie content in foods). So based on this, the question is a bit of a non-sequitur. But if you disregard that and go with a regular answer, it really depends on what kind of calories you're ingesting because foods get digested in a function of different amounts of time. Carbohydrates will get digested and converted into glucose almost immediately - being very close to 100% energy efficiency. Fats are the slowest as your body needs to produce bile in order to digest it - not enough bile = undigested fat = unused calories. Proteins are turned into either amino acids (not an energy source per se) or converted into glucose like carbs but instead through gluconeogenesis which is a less efficient form of glucose conversion than carbohydrates (since your liver/kidneys need to produce the enzymes to convert it). The efficiency of protein is likely in the range of 50-60% calories. This is just the tip of the iceberg though - your metabolism also plays a part as to how much and when these calories are either used, stored, and excreted by your body. Ever got the meat sweats? That's your body burning excess energy through thermogenesis when you eat too much protein. So it really depends why you're asking because the answer will differ for each scenario.
