Answer:
Cell A:[tex]SA:V=5\mu m^2/\mu m^3[/tex]
Cell B:[tex]SA:V=2\mu m^2/\mu m^3[/tex]
The SA:V ratio of the cell that will exchange materials with its environment at the fastest rate is 5μm²/μm³Explanation:
1. Show the data properly:
Cell A:
Surface area:
[tex]SA=50\mu m^2[/tex]
Volume:
[tex]V=10\mu m^3[/tex]
Cell B:
Surface area:
[tex]SA=14\mu m^2[/tex]
Volume:
[tex]V=7\mu m^3[/tex]
2. Find the surface-to-volume ratio of each cell.
Cell A:
SA: V
[tex]50\mu m^2/10\mu m^3=5\mu m^2/\mu m^3[/tex]
Cell B:
SA:V
[tex]14\mu m^2/7\mu m^3=2\mu m^2/\mu m^3[/tex]
3. Compare
The cell that will exchange materials with its environment at the fastest rate of diffusion is that with the greater SA:V ratio. That is cell A.
The reason is that a greater surface in relation to the volume the cell contain means that it has a bigger area to permit the exchange of the materials.
A cake has two layers. Each layer is a regular hexagonal prism. You cut and remove a slice that takes away one face of each prism as shown. What is the volume of the slice? What is the volume of the remaining cake? Use pencil and paper. Describe two ways to find the volume of the slice.
Answer:
Volume of slice is approximately 40 in³
Volume of the remaining cake is 197.014 in³
Explanation:
Here we have two regular hexagons
one top small hexagon cake with side length = 3 in, height = 3 in
One big hexagon cake, side length = 4 in, Height = 4 in
A slice cut such the it removes a side segment is equivalent to an equilateral triangle with side length = length of hexagon side
Also all angles within the equilateral triangle are 60° each
Therefore, the length of the side of the removed equilateral triangle side is given as follows;
Top small cake slice triangle side = 3 in.
Area of surface of small slice = [tex]\frac{1}{2} \times Base \times Height = \frac{1}{2} \times 3 \times 3\times sin(60) = \frac{1}{2} \times 3 \times 3 \times \frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{4}[/tex]
Volume of small slice = Area of surface small slice × Height of small cake
= [tex]\frac{9\sqrt{3} }{4} \times 3 = \frac{27\sqrt{3} }{4} =11.69 \ in^3 \approx 12 \ in^3[/tex]
For the big cake, we have;
Big cake slice triangle side = 4 in.
Area of surface of big slice = [tex]\frac{1}{2} \times Base \times Height = \frac{1}{2} \times 4 \times 4\times sin(60) = 8 \times \frac{\sqrt{3} }{2} = 4\sqrt{3}[/tex]
Volume of big slice = Area of surface of big slice × Height of big slice
= [tex]4\sqrt{3} \times 4 = 16\sqrt{3} =27.71 \ in^3 \approx 28 \ in^3[/tex]
Total volume of slice = Volume of small slice + Volume of big slice
Total volume of slice = 12 in³ +28 in³ = 40 in³
The volume of the remaining cake can be found by noting that there were 6 possible slices of cake based on the 6 sides of the hexagon, since we removed 1 slice, the remaining 5 slices will have a volume given by multiplying the volume of 1 slice by 5 as follows;
For the small cake, the remaining volume = [tex]5 \times \frac{27\sqrt{3} }{4} = 5 \times 11.69 \ in^3 = 58.45 \ in^3[/tex]
For the big cake the remaining volume = [tex]5 \times 16\sqrt{3} = 5 \times 27.71 \ in^3 = 138.56 \ in^3[/tex]
Total volume remaining cake = 58.45 in³ + 138.56 in³ = 197.014 in³
Together with the above way to find the volume of slice of cake, the volume of the slice can also be found by considering that the cake, with a shape of a regular hexagon is made up of 6 such slices. Therefore, if the volume of a regular hexagon is as follows;
[tex]Volume\, of \, regular \, hexagon, \ A = \frac{3\sqrt{3} }{2} a^2 \times h[/tex]
Where:
a = Length of side
h = Height of hexagon
The volume of each slice is therefore,
[tex]\frac{Volume\, of \, regular \, hexagon, \ A }{6} =\frac{ \frac{3\sqrt{3} }{2} a^2 \times h}{6} = a^2 \times h \times \frac{3\sqrt{3} }{12} = a^2 \times h \times \frac{\sqrt{3} }{4}[/tex]
For the small cake, we have
a = 3 in.
h = 3 in.
Volume of small slice = [tex]a^2 \times h \times \frac{\sqrt{3} }{4} = \frac{3^2\sqrt{3} }{4} \times 3 = \frac{27\sqrt{3} }{4} \ in^3[/tex].
For the big cake, we have
a = 4 in.
h = 4 in.
Volume of big slice = [tex]a^2 \times h \times \frac{\sqrt{3} }{4} = \frac{4^2\sqrt{3} }{4} \times 4 = 16\sqrt{3} \ in^3[/tex].
Total volume of slice = Volume of small slice + Volume of big slice
Total volume of slice = [tex]\frac{27\sqrt{3} }{4} \ in^3 +16\sqrt{3} \ in^3 = \frac{91\sqrt{3} }{4} \ in^3 = 39.404 \ in^3[/tex]
Total volume of slice = 39404 in³.
Answer:
The volume of slice is 142
The volume of the remaining cake is 708

1Explain how global trade networks have shifted agriculture to extensive commercial operations. 2Explain how global cities are attracting more international migrants then smaller places. 3Compare the impact of global trade networks on the labor market.
Answer:
1) global trade network has shifted agriculture to extensive commercial operations due to the fact that the trading across borders encourages increase in demand for an agricultural product by ensuring an increased consumers size. This has permitted extensive development and commercialization of agriculture as agricultural goods now find their way into countries they originally were not marketed in prompting methods of mass and timely production of this goods.
2) global cities are attracting more international migrants then smaller places basically and most importantly because of their industrial and socioeconomic development. These developments encourages industrial productivity which can support a growing labor force. Migrant hoping for better quality of life are drawn to these global cities hoping to increase their earning power. Other factors such as security, developed health care system and infrastructure all contribute to migrant influx into global cities.
3) the impact of global trade networks on the labor market is without question one of the most important benefits of global trading. Global trading allows increased productivity of industries. Increase in productivity means the industries can support a more robust and fulfilled labor workforce, therefore, countries that are focused on global trading will have a more fulfilled labor market.

why do you think they limit navigational dredging in the hudson
Answer:
They limit navigational dredging because they need the water to fulfill other needs such as people's water supply.
They limited navigational dredging in the Hudson because fish advisories and wildlife contamination will last for decades after the cleanup is completed.
What is navigation?Navigation is the process of measuring and managing the motion of a craft or steering wheel from one location to another.
The inland environment was not conducive to large-scale agriculture. Phoenicians took advantage of their location in a narrow coastal corridor that connected Asia to Africa. A satellite image of modern-day Tunisia's Carthage jutting into the Mediterranean Sea.
Therefore, huge quantities of potentially polluted sediments will not be dug up during the cleanup, which means that fish advisories and wildlife contamination will continue for centuries after the cleanup is completed.

What caused shyness and what can be done about it?
Shyness, which can be anxious or self-conscious, is typically a discomfort during social interactions, possibly stemming from a range of causes like fear of evaluation, privacy breaches, or teasing. In contrast, social anxiety disorder is an extreme form of social discomfort that significantly impairs daily functioning. Overcoming these forms of social discomfort can involve gradual, structured exposure to feared situations.
Explanation:Shyness is a common experience associated with discomfort in social settings, and according to Arnold Buss, it can be categorized into anxious shyness and self-conscious shyness. Anxious shyness is characterized by the fear of face-to-face interactions, which can stem from strangers, novel settings, the fear of evaluation, or fear of self-presentation, leading to chronic fear, low sociability, low self-esteem, loneliness, and avoidance conditioning. In contrast, self-conscious shyness involves feeling conspicuous or exposed, often beginning with experiences of conspicuousness, privacy breaches, or teasing, and can develop into socialization issues, public self-consciousness, a history of teasing, low self-esteem, negative self-appearance, and poor social skills.
An effective approach to overcoming social anxiety disorder, which differs from shyness by its greater intensity and interference with normal life, involves exposure to feared social situations. For example, those afraid of public speaking could start by talking in front of a small, supportive audience and gradually increase the audience size. Additionally, engaging in structured small talk scenarios or practicing activities like writing or eating in front of others in a controlled environment might help individuals overcome their fears.
Differentiating between Shyness and Social AnxietyWhile shyness is a general discomfort in social interactions, social anxiety disorder presents a more extreme form of discomfort and often results in significant distress and impairment in social, occupational, or other important areas of functioning. Some evolutionary developmental psychologists suggest that traits like shyness may have genetic components that historically increased survival rates. However, it's crucial to note that while some level of anxiety can be motivating, when it interferes with one's ability to function, as in social phobia, it becomes a concern that may require intervention.
Which is NOT an example of what can be done with GIS? A mapping change B mapping densities mapping quantities D) mapping the human genome E) mapping where things are
Answer:
Option D
Mapping the human genome
Explanation:
GIS means Geographic Information System. It was specifically built to map and study spatial geographic information. The options aside option D, are related to geographic data. This means that the GIS can perform them with ease and high accuracy.
However, mapping the human genome to a certain extent, is out of the scope of the GIS and cannot be performed well using such systems. This is because it is not geographical data, rather, human cellular data. Additional tools will need to be applied before this can be done well.
This makes option D the answer

Demographic push factor for less developed countries
Demographic push factors refer to factors that force or push people to leave their homeland and migrate elsewhere. In this scenario, the working population in underdeveloped countries seeks better economic opportunities and higher wages.
They are motivated to migrate to more developed countries, where they believe they will have better job prospects, higher incomes, and improved living standards.
This driving factor is driven by economic considerations and the desire to improve financial situation. Individuals and families may choose to leave their homeland in search of better job opportunities and a higher standard of living.
