The presence of large proteins in Stella's urine is due to a problem with filtration.
A problem with filtration is responsible for John's blood test report indicates a high toxin level
A problem with secretion is the reason why Miguel's blood test shows an increase in metabolic waste.
A problem with secretion is why Janice's urine report shows the presence of vital minerals.
What is a nephron?A nephron is the functional unit of the kidneys that is responsible for the formation of urine.
Each nephron has a structure for blood filtration known as the glomerulus. The glomerulus is a network of capillaries that is surrounded by the Bowman’s capsule or the glomerular capsule which is a cup-like structure.
During filtration by the nephron, water and minerals are filtered out of the blood.
During secretion, small molecules such as waste minerals and hydrogen ions pass from the capillaries into the renal tubule and are removed as urine.

compared to blood capillaries, lymphatic capillaries__________.
Answers
Compared to blood capillaries, lymphatic capillaries are larger in diameter and possess closed ends.
What is the function of lymphatic capillaries?The function of lymphatic capillaries deals with the process of keeping the overall balance of fluid in your body. This function is stimulated by returning the interstitial fluid back into the circulatory system with the help of lymph capillaries.
In blood capillaries, fluid can never being flowed but in lymph capillaries, fluid can easily flow throughout the cell walls. But the movement of this fluid is only permitted in the forwarding direction. This is also the unique feature of lymphatic capillaries.
Therefore, the major difference between blood capillaries and lymphatic capillaries is that lymph capillaries are larger in size.

I hope this helps!compare and contrast aerobic respiration, anaerobic respiration, and fermentation.
Answers
Answer:
Aerobic respiration is the type of cellular respiration that takes place in the presence of oxygen.
Anaerobic respiration is the type of cellular respiration that takes place in the absence of oxygen.
Fermentation is the process of chemical reaction in which sugar gets converted into carbon dioxide and ethanol induced by micro-organisms.
Explanation:
Aerobic respiration is found in all higher animals and plants.
Anaerobic respiration is found in micro-organisms but rarely in higher organisms.
Fermentation is found in bacteria and some other higher animals (muscle cells in humans).
Aerobic respiration take place in the cytoplasm (glycolysis) and mitochondria (Krebs cycle and electron transport chain).
Anaerobic respiration takes places only in the cytoplasm.
Fermentation belongs to the anaerobic respiration and it takes place in the cytoplasm only.
Aerobic respiration produces 36 ATPs per glucose molecule.
Anaerobic respiration produces 2 ATPs per glucose molecule.
Fermentation produces 2 ATPs per glucose molecule.
Aerobic respiration: carbon dioxide and water.
Anaerobic respiration: lactic acid in animals; carbon dioxide and ethanol in plants or yeast.

The fur color of collared lemmings changes to white at a certain time of the year.
a. Explain how the change in fur color is an advantage to collared lemmings. When temperatures rise above freezing, snow melts, which causes changes in the collared lemmings’ habitat.
b. Describe two ways warming temperatures could cause the size of the collared lemming population to decrease.
c. Describe how fur color in the collared lemming population will likely change over time as temperatures increase because of climate change.
Answers
The change in fur color of collared lemmings is an advantage in the face of rising temperatures because their snow color will make them easily vulnerable to predators.
What is adaptation?The term adaptation refers to the morphological or physiological changes that an organism undergoes in order to survive efficiently in its environment.
The change in fur color of collared lemmings is an advantage in the face of rising temperatures because their snow color will make them easily vulnerable to predators when the snow eventually melts.
The rise in temperature will cause physiological changes in the the population of the collared lemmings which could reduce their population size. Also, predators can now access them more easily as they become more visible.
As time goes on, the snow color of the collared lemmings will eventually change as the animal will have to take on colors that will enable it to blend again with its new habitat and escape predators.

What will be the economic and social consequences of this loss of biodiversity? Can anyone help please?
Answers
Answer:
economic consequences
Whilst human-made changes to ecosystems have often generated large economic gains, biodiversity loss damages the functioning of ecosystems and leads to a decline in essential services, which may have severe economic consequences, particularly in the longer term.
social consequences
Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, local migration and, on occasion, may even cause or exacerbate political conflict

Answers
Answer:
Explanation:
pt.1 There are three major types of rocks: Metamorphic, Igneous, and Sedimentary. Metamorphic Rocks - Metamorphic rocks are formed by great heat and pressure. They are generally found inside the Earth's crust where there is enough heat and pressure to form the rocks. Metamorphic rocks are often made from other types of rock.

You discover a new type of marine organism that has the kidneys of a fish but no gills. Based on what you know about other aquatic organisms, the newly discovered organism is _____ compared to the surrounding water. hypotonic isotonic hypertonic
Answers
The newly discovered organism is hypotonic compared to the surrounding water. Thus, the correct option for this question is A.
What will happen if aquatic organisms have kidneys?The function of the kidneys in aquatic organisms is to excrete excess water by retaining most of the filtered solutes. This makes the aquatic organisms more survival because the retaining of solutes gives more energy.
If the newly discovered organism is hypotonic to the surrounding water, it takes the water from the surrounding atmosphere which is then excreted by the kidney through the retention of filtered solutes. This mechanism is accomplished by simple diffusion. While gills are not present in the newly formed organism.
Therefore, the newly discovered organism is hypotonic compared to the surrounding water. Thus, the correct option for this question is A.
