Answer:
1. Muscles function in movement of the head, neck, and limbs, as well as propulsion of the contents through the digestive tract.
2. Muscles function in stability by preventing unwanted movement, as in maintaining posture.
3. Using sphincters, or valves, muscles control the passage of contents from one body cavity or lumen to another.
4. Since muscle contraction requires energy to do work, movement muscles help maintain our body heat.
5. By absorbing a large share of one's glucose, muscles play an important role in blood sugar control.
Explanation:
Muscles have different functions in the body. They allow our head, neck and limbs to move, and also have an important role in the propulsion of contents through the digestive track.
Muscles are soft tissues that also have a role in stability by maintaining posture and help the passage of contents from different cavities by using sphincters.
Their main source of energy is glucose in the body. By using this energy, muscles help to maintain our bodies temperature and blood sugar control.

Is your prediction supported by the membrane potential chart? Explain your answer.
Answer:
Yes, it is. The chart shows that the initial charge of the neuron is negative. When the neuron is stimulated, sodium ions enter the cell. So, the voltage inside the cell changes to positive. When potassium ions move outward, the voltage decreases until it reaches its previous state.

What is the main function of the nervous system and how is it structured?The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
Conclusion: The nervous system is a highly integrated system. The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.

Explain in a few sentences how the carbon, nitrogen, and phosphorus overlap. How do these cycles cross paths through earths spheres?
Answer:
Explanation:Energy flow and nutrient circulation are the major functions of the ecosystem.
Energy is lost as heat forever in terms of the usefulness of the system. On the other hand, nutrients of food matter never get used up. They can be recycled again and again indefinitely.
Carbon, hydrogen, oxygen, nitrogen and phosphorus as elements and compounds makeup 97% of the mass of our bodies and are more than 95% of the mass of all living organisms.
In addition to these, about 15 to 25 other elements are needed in some form for the survival and good health of plants and animals.
These elements or mineral nutrients are always in circulation moving from non-living to living and then back to the non-living components of the ecosystem in a more or less circular fashion.
This circular fashion is known as biogeochemical cycling (bio for living; geo for atmosphere).
Among the most important nutrient cycles are the carbon nutrient cycle and the nitrogen nutrient cycle.
There are many other nutrient cycles that are important in ecology, including a large number of trace mineral nutrient cycles.
The Ebola virus can often have symptoms similar to bacterial pneumonia, an infection of the lungs. These symptoms include chest pains, shortness of breath, and fever. Which statement best summarizes the differences between these two diseases? (SC.6.L.14.6)a.Viruses can replicate because they are living organisms, while bacteria cannot. b.Viruses are not living organisms, but bacteria are living. c.Viruses can be beneficial to live organisms but bacteria are often infectious. d.Viruses are living organisms, while bacteria are not.
Answer:
Eblow is a terrible thing.
Explanation:
Answer:
I think its, option b) Viruses are not living organisms, but bacteria are living.
Explanation:
The other options don't fit "summarize the differences b/w bacteria and virus", or simply don't make sense...
Bacteria can replicate as well, not only virus, so that cannot be a difference
The virus is often the one being more dangerous, there is something called "good bacteria"
A virus isn't living, (for the sake of this answer), and we all know for sure that bacteria is living
So, that's how option b is correct

How do plants contribute to the water cycle?
Answer:
Plants absorb water from the soil. The water moves from the roots through the stems to the leaves. Once water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration.
I really hope this helps!
Plants contribute to the water cycle in several ways through Transpiration, evaporation, Precipitation: and infiltration.
How do we explain?Plants take in water through their roots and transport it up to their leaves. As water evaporates from the leaves, it creates a force that pulls more water up from the roots through a process called transpiration, and it is a major way that water moves through the atmosphere.
Water from plants and soil also evaporates into the atmosphere. This process is called evaporation, and it is another important way that water moves through the water cycle.
When water vapor in the atmosphere cools, it condenses and falls back to Earth as precipitation. This can be in the form of rain, snow, sleet, or hail.

Explanation:
Suppose we stock a pond with 100 fish and note that the population doubles in the first year (with no harvesting), but after a number of years, the population stabilizes at what we think must be the carrying capacity of the pond: 2,000 fish. Growth seems to have followed a logistic curve. a. What population size should be maintained to achieve maximum yield, and what would be the maximum sustainable fish yield? b. If the population is maintained at 1,500 fish, what would be the sustainable yield?
Answer:
Explanation:
From the given information,
The first process is to determine the initial growth rate by using the formula:
[tex]R_o = \dfrac{In(2)}{t_d}[/tex]
where;
The initial growth rate(constant) = [tex]R_o[/tex] ; &
the doubling time = [tex]t_d[/tex] = 1 year
[tex]R_o = \dfrac{In(2)}{1 \ year}[/tex]
[tex]R_o[/tex] = 0.693 / year
Now, we move up to the net stage to find the growth constant by using the formula:
[tex]r = \dfrac{R_o}{(1 - \dfrac{N_o}{K})}[/tex]
where;
[tex]N_o[/tex] = population of fish in the pond = 100
[tex]R_o[/tex] = The initial growth rate(constant) = 0.693 /year
K = carrying capacity = 2000
Then;
[tex]r = \dfrac{0.693 \ /year }{(1 - \dfrac{100}{2000})}[/tex]
[tex]r = \dfrac{0.693 \ /year }{(1 - 0.05)}[/tex]
[tex]r = \dfrac{0.693 \ /year }{(0.95)}[/tex]
r = 0.730 / year
a)
Now, the maximum yield can be evaluated by using the expression:
[tex]= \dfrac{rk}{4}[/tex]
[tex]= \dfrac{0.730 \times 2000}{4}[/tex]
= 365 fish per year
Also, the maximum sustainable yield is said to be half of the carrying capacity suppose that the population growth obeys logistic curve;
i.e.
[tex]N' = \dfrac{1}{2} \times 2000[/tex]
N' = 1000 fish
b)
If the population is maintained at 1500 fish;
The sustainable yield can be calculated by using the formula:
The Sustainable yield = [tex]r\times N (1 - \dfrac{N}{K})[/tex]
The Sustainable yield = [tex](0.730/ year ) (1500) (1 - \dfrac{1500}{2000})[/tex]
The Sustainable yield = 1095 × 0.25
The Sustainable yield = 273.75 fish per year
The Sustainable yield ≅ 274 fish per year
Population size should be maintained to achieve maximum yield and Sustainable yield if population is maintained at 1,500 fish are 364.7 , 273.525 fish per year
Sustainable yield:Given that;
Stock in start = 100 fish
Double in 1 year
Capacity of pond = 2000 fish
Find:
Population size should be maintained to achieve maximum yield
Sustainable yield if population is maintained at 1,500 fish
Computation:
Growth rate = ln₂ / 1
Growth rate = 0.693 per year
With no growth constraint r = [tex]\frac{0.693}{1-\frac{100}{2000} }[/tex]
With no growth constraint r = 0.7294 per year
A. Population size should be maintained to achieve maximum yield = [tex]\frac{0.7294 \times 2000}{4}[/tex]
Population size should be maintained to achieve maximum yield = 364.7 fish per year
B. Sustainable yield if population is maintained at 1,500 fish = [tex][(0.7294))(1500)][1-\frac{1500}{2000} ][/tex]
Sustainable yield if population is maintained at 1,500 fish = 273.525 fish per year
