In the digestive system many large molecules, such as proteins, are broken down into much smaller molecules. State what happens to these smaller molecules following digestion.

Answers

Smaller molecules are taken up into the bloodstream by epithelial cells that line the walls of the small intestine. The waste continues to the colon where water is absorbed and the dried waste is compacted into feces. It is stored until excreted from the anus through the digestive system

The digestive system breaks down the food we eat into its simplest forms: glucose (sugar), amino acids (which make up protein), and fatty acids (which make up fat). Absorbed by the flow, the nutrients are carried to every cell in the body.

The human digestive system consists of the gastrointestinal tract and the accessory digestive organs. Digestion breaks down food into smaller and smaller components until they are absorbed and absorbed by the body.

What should be done first in neonatal resuscitation?

Answers

In neonatal resuscitation firstly the newborn should be placed under a radiant heat source to offer warmth.

The baby should then be dried off, their airway should be cleared with a bulb syringe or suction catheter if necessary, and their breathing should be stimulated.

Clear the airway by suctioning the mouth first, followed by the nose, with a bulb syringe or suction catheter if the baby is energetic at birth (strong respiratory effort, such as crying, good muscular tone, heart rate > 100 bpm). If bradycardia develops when sucking, cease sucking and reassess the heart rate. Suctioning for intubation is not necessary.

The newborn needs tracheal suctioning if they are not active (decreased breathing, depressed muscle tone, and heart rate 100 bpm). Using a laryngoscope and a suction catheter under direct eyesight, first clean the mouth and posterior pharynx before inserting the endotracheal tube into the trachea. Connect an apparatus for suction to the endotracheal tube. As the tube is gently withdrawn, use suction. Repeat as necessary until the meconium is recovered or the heart rate drops down below 60 beats per minute, at which point immediate resuscitation is required. Give a soft yet forceful stimulation; touch the back and softly flick the soles.

Answers

Thickness of the ozone layer id not the one that disrupt and degrade freshwater systems.

The stratosphere, 15–40 km above the earth's surface, may include the ozone layer. Under typical pressure and temperature circumstances, the ozone layer in the stratosphere is between 2 and 5 mm thick, and the amount of ozone present varies by season, hour of the day, and location. Ozone builds up in the polar area due to poor photochemical depletion and ozone transfer from the equator. In the absence of other ozone-disturbing components, the highest ozone values are therefore observed over the Polar regions in winter. Wetlands are often referred to be areas of land that are either permanently saturated with moisture or immersed in shallow water.

Perhaps the strongest fossil evidence for evolution is the continuity of the fossil record from prehistoric to modern times.

The Devonian, the age of the fishes, or human fossils amid dinosaur remains are not things we discover anyplace on Earth. The five assumptions that Darwin combined are evolution, or common descent, gradualism, species diversity, and natural selection. A theory is a reason for how a natural phenomena works that has been put to the test extensively through observations and tests meant to prove the correctness of the explanation.

Desde hace siglos el cauce de los ríos no se aprovechó con molinos y rotores para aprovechar su fuerza y convertirla en energía mecánica.

Answers

Answer:

Falso (este principio es la base de la energía hidráulica la cual ha sido utilizada por siglos)

Explanation:

La energía hidráulica es un tipo de energía obtenida a partir del aprovechamiento de las corrientes de agua. La humanidad ha utilizado desde hace siglos la energía hidráulica producida por la corrientes de aguas de los ríos conectados con pequeña represas a fin de mover molinos y rotores, y así convertir la energía hídrica en energía mecánica, la cual a su vez puede ser utilizada para moler granos de cereales (molinos harineros) y también (más recientemente) para la generación de energía eléctrica. Las centrales hidroeléctricas representan la principal aplicación de la energía hidráulica en la actualidad. Las centrales hidroeléctricas utilizan el mismo principio que estos antiguos molineros harineros para producir energía, aprovechando la energía potencial del cauce del agua y su caída a un nivel inferior del cauce. En el caso de las centrales hidráulicas, el agua que cae se hace pasar por turbinas hidráulicas conectadas a un generador que produce energía eléctrica. La energía hidráulica representa un tipo de energía limpia con un gran potencial de rendimiento energético.

When describing DNA replication we say that DNA polymerase synthesizes the new strand in a 5' to 3' direction, moving down the template strand from 3' to 5'. Briefly explain why replication always proceeds in this direction

Answers

DNA replication occurs in a 5' to 3' direction because the enzymes used for replication, known as DNA polymerases, can only add nucleotides to the 3' end of an existing strand of DNA.

This is because the 3' end has an exposed hydroxyl (-OH) group which can be used to add to the growing strand of nucleotides. As such, the polymerase moves down the template strand from 3' to 5', adding new nucleotides in the 5' to 3' direction.

This ensures that the newly synthesised strand is complementary to the template strand, as newly added nucleotides are added in the same direction as the original strand.

Additionally, this directional synthesis also means that both strands of the DNA double helix can be synthesised simultaneously, with each strand serving as the template for the other. This ensures that the complete DNA molecule is correctly replicated in the same manner as the original strand.

How is local humidity influenced by a flow of energy and the movement of matter in the form of water?

Answers

Answer: Evaporation!

Explanation:

One way in which energy can influence local humidity is through the process of evaporation. When energy is added to water, it can cause the molecules to vibrate more rapidly, which can eventually cause them to break free from the surface and turn into a gas. This process, called evaporation, can increase the amount of water vapor in the air, leading to higher humidity.

Answer:

The local humidity is influenced by the flow of energy and the movement of water in the air because these factors determine the amount of water vapor that the air can hold. The amount of water vapor that air can hold is directly related to its temperature - as the air temperature increases, the air can hold more water vapor. When the air is already saturated with water vapor, any additional moisture will condense into visible droplets, such as dew or fog. This process is known as condensation.

The movement of water in the air can also affect local humidity. If moist air moves into an area, it can increase the humidity in that area. Conversely, if dry air moves into an area, it can decrease the humidity. The movement of water in the air can be caused by a variety of factors, including differences in temperature and pressure, the presence of physical barriers, and the force of the wind.

Environmental variation refers to an organism's capacity to significantly vary its PHENOTYPE in response to environmental factors. Plants exhibit the phenomenon the most clearly, possibly because they are permanently rooted in the earth. For instance, if a dandelion is planted in a garden border with other plants, it will develop an upright posture with long blossom stalks. If cultivated on a garden lawn, a different dandelion with a similar genotype will result in a PROCUMBENT habit with short flower stalks.

Climate, diet, accidents, culture, and way of life are only a few examples of the variables that might have an impact on an animal's or plant's characteristics. For instance, you will put on weight if you eat too much, and you will lose weight if you eat too little.

The various greenhouse gases' varying contributions to global warming are as follows: planting trees can reduce CO2 by 60%. More carbon dioxide is removed from the atmosphere by trees than is released.

What effects of global warming have you personally noticed? How has it influenced the planet thus far?

Storms, heat waves, floods, and droughts are just a few of the disasters that are getting worse as a result of rising temperatures. Warmer temperatures produce an atmosphere that can hold onto, release, and gather more water. This alters weather patterns such that wet areas get wetter and dry ones to get drier.

How are climate change and global warming-related?

The heat from the sun gets trapped on Earth as a result of greenhouse gas production. Global warming and climate change result from this.
