Answer:
Proteinuria occurs when the filtration membrane becomes leaky, allowing proteins to cross. This impacts the blood colloid osmotic pressure by decreasing the osmolarity gradient between the blood and filtrate, thereby reducing the strength of this pressure.
Explanation:
Proteinuria is the medical term that describes the presence of proteins in the urine.Proteins, in normal conditions, are not capable of filtrating through the membrane but, in the presence of a disease, this is possible.
Proteins are responsible for the colloid osmotic pressure in the blood vessels, so when proteins get filtered, this pressure decreases and so does the osmolarity gradient between the blood and filtrate. The decrease in osmolarity gradient also produces a decrease of the colloid osmotic pressure because the strength of the pressure is as big as the gradient between the two compartments.
ribose, phosphate, uracil
b
deoxyribose, phosphate, uracil
c
ribose, phosphate, thymine
d
deoxyribose, phosphate, cytosine
b. coral reefs
c. rivers
d. ponds
B. coral reefs because marshes, rivers and ponds have nothing to do with the ocean ecosystem.
The completed question is,
Identify the biotic factor of an ecosystem from the following:
a. soil composition
b. trees
c. temperature
d. sunlight
Option b. trees are the biotic factor of an ecosystem.
An ecosystem includes all the organisms and the physical environment with which they interact. These biotic and abiotic components exist linked together through nutrient cycles and energy flows. The energy penetrates the system through photosynthesis and exists incorporated into plant tissue.
The primary types of ecosystems are forests, grasslands, deserts, tundra, freshwater, and marine. The word “biome” may even be used to represent terrestrial ecosystems that extend across a large geographic area, such as the tundra.
With the provided choices. it exists trees that are categorized as biotic factors of an ecosystem. Biotic factor guides living things found in the ecosystem. Trees exist as living things that furnish oxygen for humans and animals to live.
Hence, Option b. trees are the biotic factor of an ecosystem.
