Answer:
A B and C but not D
Explanation:
Moving from a Hight concentration gradient to a low concentration gradient means moving from an area where a substance in quantity to an area where it is lower in quantity. D is the only one showing something to be moved against a concentration gradient because there are more squares inside the cell than outside the cell yet the squares are still being moved into the cell.

Magma is molten (liquid) rock under Earth’s surface. Based on the image, how do you think magma turns into extrusive igneous rock?
Answers
Answer:
Magma come out of volcanoes that cools down and later on hardens up into rocks.
Explanation:
Magma come out of volcanoes that cools down and later on hardens up into rocks.
What is Magma?The existence of magma is essential to comprehending the geology and morphology of the mantle because the majority of the mantle and crust are solid.
Different types of magma form as a result of variations in the mantle's and crust's structural features, pressure, and temperature. Decompression Melting The mainly solid mantle of the Earth moves higher during decompression melting.
Convection causes this hot material to rise to a place with lower pressure.
Therefore, Magma come out of volcanoes that cools down and later on hardens up into rocks.

Taking into account the definition of Avogadro's number, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.
Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance.
Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of moles in this caseIn this case, you have 2 moles of Fe(NO₃)₂.
Then you can apply the following rule of three: If 1 mole of the compound contains 6.023×10²³ molecules, 2 moles of the compound contains how many molecules?
amount of molecules= (6.023×10²³ atoms× 2 moles)÷ 1 mole
amount of molecules= 1.2046×10²⁴
Finally, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.

The appendix, an extension of the large intestine appears, although this is debated, to have little
function in humans. What is the appendix an example of in terms of evidence for evolution?
Answers
Answer: Vestigial organ
Explanation:
Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.
The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.

Your body uses feedback mechanisms to help maintain a stable internal environment called homeostasis. Changes can come from outside or inside the body and the body must respond to these adverse changes to return to a steady state. One such example is what happens when you go for a run on a hot summer day and your body temperature increases. According to the diagram, one of the mechanisms used to cool down is vasodilation. Similar mechanisms are also used when your body temperature drops due to a cold environment. Which of these would NOT help return a body to homeostasis by increasing body temperature?
A) shivering
B) vasoconstriction
C) muscles contract
D) increasing blood pressure
Answers
Answer:
Option D increasing blood pressure.
Explanation:
Increasing blood pressure
What is feedback mechanism in homeostasis?
Homeostasis is generally maintained by a negative feedback loop that includes a stimulus , sensor , control center , and effector . Negative feedback serves to reduce an excessive response and to keep a variable within the normal range.
What are the two feedback mechanisms which work to maintain homeostasis?
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?
(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:
7th Edition - Chapter 17
9th Edition - Chapter 14
Answers
Answer:
Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path. Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.
