1. What is the significance of the specific gravity of the abnormal urine?
Answer:
A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
Explanation:
Urine specific gravity is a significant and convenient way to measure the abnormal urine. It indicates dehydration or presence of substances in the urine as in case of diabetes.
What is Specific gravity?
Urine specific gravity (USG) measures the concentration of particles which are present in the urine and the density of urine compared with the density of water. Measurement of USG is an easy way and very convenient way to know a patient's hydration status as well as the functional ability of kidneys.
Urine specific gravity falls between the range of 1.002 and 1.030 if the kidneys are functioning normally. However, if specific gravity results above 1.010 this can indicate mild dehydration in that person. The higher the number of specific gravity, the more dehydrated a person may be.
A very high specific gravity means very concentrated urine, which may be due to not drinking enough fluid, loss of too much fluid, or substances such as sugar or protein in the urine.

describe how energy is transferred through a food chain
PLSS ANSWER IM BEGGING YOU
Well energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.on:
Answer:
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary consumers.
explain why norepinephrine requires a protein receptor to exert its effects.
Answer:
I'm going off the top of my head for this one, and this is an educated guess, so check it if you would like to. When the norepinephrine binds to a protein, then the protein relays the info to the cells that are required to do the specific action. This is why we feel a sense of stress, elevated heart rates, or high alertness.

Insectivorous birds are birds that have a diet where their primary food source is insects. In the fall and winter months in the Northeast region, the temperature starts to drop and insects become scarce. What happens to the carrying capacity for insectivorous birds in winter in a northern New York forest?
It stays constant, since carrying capacity is a fixed value that does not change.
It quickly drops to zero once the temperature goes below freezing.
It slightly fluctuates above and below the optimum level.
It rapidly increases during the winter.
The carrying capacity of the insectivorous birds in winter of the northern New York forest quickly drops to zero once the temperature goes below freezing.
What is carrying capacity?Carrying capacity refers to as the average population size of a species in a particular habitat.
The population size of a species can be affected by environmental factors such as adequate food, shelter, water, and mates etc.

differences between the three classes of platyhelminthes
Answer:
The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Class turbellaria is composed of many free-living organisms, while some are parasitic. Trematodes are commonly known as flukes. They are parasitic flatworms with an unsegmented body.
Explanation:
The three classes of Platyhelminthes are Turbellaria, Cestoda, and Trematoda.
What are the differences between the three classes of Platyhelminthes?Flatworms are members of the Platyhelminthes phylum. The Turbellaria, popularly known as planarians, the Trematode, usually known as flukes, and the Cestoda, also known as tapeworms, are the three classes that make up the phylum Platyhelminthes. Flatworm species come in more than 25,000 different varieties.
The four classes of Platyhelminthes are Cestoda (tapeworms), which are internal parasites of many vertebrates; Trematoda (internal parasites of humans and other species); and Turbellaria (free-living marine species).
Thus, these are the differences between the three classes of platyhelminthes.

What evidence did Galileo provide to support Copernicus's heliocentric model? Check all that apply.
Galileo determined the shape of each planet's orbit by a mathematical method called triangulation from different
points on Earth's orbit.
Galileo created a model showing the epicycles of the planets, which explained retrograde motion.
Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all
things.
U Galileo explained that people did not see stellar parallax because the stars were simply other suns that are very
far away.
Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Intro
Done
Answer:
- Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all things.
-Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Explanation:
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons). Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.
At about the same time, German mathematician Johannes Kepler was publishing a series of laws that describe the orbits of the planets around the Sun. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory. In 1687, Isaac Newton put the final nail in the coffin for the Aristotelian, geocentric view of the Universe. Building on Kepler’s laws, Newton explained why the planets moved as they did around the Sun and he gave the force that kept them in check a name: gravity.
