During tubular reabsorption, most of the water, glucose, and ions in the glomerular filtrate are reabsorbed into the blood whereas urea is not.
What is tubular reabsorption?Tubular reabsorption refers to.the process whereby minerals and water are reabsorped from the glomerular filtrate into the blood.
The renal artery carries mineral rich, oxygenated blood from the heart to the kidneys whereas the renal veins carry deoxygenated blood from the kidneys back to the heart.
Blood in the renal arteries contains red blood cells, white blood cells, large blood proteins, glucose, water, ions, and urea.
Filtrate in the kidney tubules contains water, glucose, ions, and urea.
Filtrate not reabsorbed is urea.
Urine contains urea, ions and water.
Blood in the renal veins contains red blood cells, white blood cells, large blood proteins, glucose, water, and ions.
Therefore, in the process of tubular reabsorption, most of the water, glucose, and ions in the glomerular filtrate are reabsorbed into the blood whereas urea is not.

Counterclockwise rotation of the flagellum causes a bacterial cell to swim or ______ towards a stimulus, interrupted by clockwise rotation in which the cell ______ and changes its course.
Answers
Counterclockwise rotation of the flagellum causes a bacterial cell to swim or run towards a stimulus, interrupted by clockwise rotation in which the cell tumbles and changes its course.
How does a bacterium respond to stimuli?A bacterium is a unicellular organism that posseses a structure called flagellum.
Flagellum in bacteria is a long, whiplike proteinaceous appendage, used for locomotion.
However, a counterclockwise rotation of the flagellum causes a bacterial cell to swim or run towards stimulus. This rotation is interrupted by a clockwise rotation of the flagellum that causes the bacterium to tumble.

Why did the students leave the amylase and starch solutions in the water bath for five minutes in step 3
Answers
Answer:
Each enzyme functions at an optimum temperature. Below the optimum temperature, the enzyme's function slows, and will eventually become inactive. Above the optimal temperature, the enzyme's activity will slow. Too far above the optimum temperature and the enzyme becomes denatured (its shape changes) and it can no longer function. Amylase is the enzyme that breaks starch (amylose) down into maltose. The amylase and the starch were placed in the water bath to allow the reaction to occur at amylase's optimum temperature of 37 C.

3. What would be an example of deposition?
Answers
Answer:
frost
Explanation:
Frost is the deposition of water vapour from humid air or air containing water vapour on to a solid surface. Solid frost is formed when a surface, for example a leaf, is at a temperature lower than the freezing point of water and the surrounding air is humid.
In sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf.

5. Which statement best describes the geocentric model of our solar system?
Answers
Answer:
Earth is at the center.
Explanation:
The geocentric model is a model system that explains how the planets in the solar system move around.
Ptolemy established the geocentric concept, which states that the earth is at the center of the solar system and that other celestial bodies, including planets and stars, rotate around it.
Nicolas Copernicus invalidated this model system by explaining that the sun is at the center of the solar system and that the planets rotate around it.

1. How do you think your organs work together to digest food?
2. What other inventions do you think are based on the functions of the digestive system?
3. How might you be able to tell that enzymes are working in your body?
4. How do different types of food change the number of digestive enzymes present in your body?
Answers
Answer:
1. Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
2.The SmartPill is an ingested, wireless device for measuring the health of the digestive system. As it passes through the digestive tract, the capsule transmits data to a receiver, which is later returned to the doctor and the information downloaded onto a laptop computer.
3. When its not working many of the uncomfortable reactions such as an upset stomach, allergy-like symptoms or irritability are actually signs that the enzymes are working. The body is cleaning itself out and the healing process is starting.
4.One of the main reasons for reduced output of digestive enzymes is poor exocrine pancreatic function. The causes of Exocrine Pancreatic Insufficiency (EPI) are very diverse ranging from: Problems with the endocrine part of the pancreas such as insulin dysregulation from diet high in refined carbohydrates and diabetes.

Explanation:
Lake Victoria in East Africa is home to many species of fish called cichlids. In 1954 the predatory Nile perch was introduced to Lake Victoria. The Nile perch became the dominant fish species in the lake by the mid-1980s. The number of cichlid species in the lake decreased as the Nile perch population increased. The perch preyed heavily on cichlid species that fed on algae and debris on the bottom of the lake. Algae in the lake increased, and oxygen levels decreased. The surface area of the gills of some cichlid species has increased in over 20 years.
A. Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch.
B. Increased gill surface area has allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch.
C. Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water.
D. Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
Answers
Answer:
D. Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
Explanation:
As the Nile perch fed on cichlid species that feed on algae, algae growth increased in the lake. The algae absorbed more oxygen, leaving less for the fish. Those with larger gills were able to absorb oxygen more efficiently, and were able to survive.
What additional procedure must be done to indicate glucose is present?
Answers
The glucose urine test estimates the amount of sugar (glucose) in a urine sample. The existence of glucose in the urine is called glycosuria or glucosuria. Glucose classes can also be calculated using a blood test or a cerebrospinal fluid test.
What is diffusion?Diffusion refers to the natural tendency of a system to homogenize the concentrations of chemical species within it.
It is an irreversible transport phenomenon that results in the migration of chemical species into a medium. Under the effect of the thermal agitation, a displacement of the constituents of the zones of high concentration towards those of low concentration is observed.

Some cons of having invasive species include capable of causing extinction to native species. Also, taking away possible food or eating eggs from native plants and animals. Lastly, invasive species can take away all sorts of habitats in all different ecosystems.
People that might care about this situation includes any normal citizens and biologists. This is true because they both have a big say in changing other peoples thoughts and can notice their surroundings. If everyone cared about this problem many invasive issues would go away and many places would have their native species back in order to save them from extinction.
