Explanation:
List the Earth’s 4 spheres and give 1 example from your Environment for 2 of the speres.
Answer:
read this
Earth's Spheres
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air). Each of these four spheres can be further divided into sub-spheres. To keep things simple in this course, there will be no distinction among the sub-spheres of any of the four major spheres.
Lithosphere - Land
The lithosphere contains all of the cold, hard solid land of the planet's crust (surface), the semi-solid land underneath the crust, and the liquid land near the center of the planet.* The surface of the lithosphere is very uneven (see image on right). There are high mountain ranges like the Rockies and Andes (shown in red), huge plains or flat areas like those in Texas, Iowa, and Brazil (shown in green), and deep valleys along the ocean floor (shown in blue).
The solid, semi-solid, and liquid land of the lithosphere form layers that are physically and chemically different. If someone were to cut through Earth to its center, these layers would be revealed like the layers of an onion (see right image above). The outermost layer of the lithosphere consists of loose soil rich in nutrients, oxygen, and silicon. Beneath that layer lies a very thin, solid crust of oxygen and silicon. Next is a thick, semi-solid mantle of oxygen, silicon, iron, and magnesium. Below that is a liquid outer core of nickel and iron. At the center of Earth is a solid inner core of nickel and iron.
* Note: The word "lithosphere" can take on different meanings depending on the speaker and the audience. For example, many geologists--scientists who study the geologic formations of Earth--reserve the word "lithosphere" to mean only the cold, hard surface of Earth, not the entire inside of the planet. For the purpose of this course, however, there will be no distinction among the various layers of land. The word "lithosphere" will be used in reference to all land in Earth's system.
Hydrosphere - Water
The hydrosphere contains all the solid, liquid, and gaseous water of the planet.** It ranges from 10 to 20 kilometers in thickness. The hydrosphere extends from Earth's surface downward several kilometers into the lithosphere and upward about 12 kilometers into the atmosphere.
A small portion of the water in the hydrosphere is fresh (non-salty). This water flows as precipitation from the atmosphere down to Earth's surface, as rivers and streams along Earth's surface, and as groundwater beneath Earth's surface. Most of Earth's fresh water, however, is frozen.
Ninety-seven percent of Earth's water is salty. The salty water collects in deep valleys along Earth's surface. These large collections of salty water are referred to as oceans. The image above depicts the different temperatures one would find on oceans' surfaces. Water near the poles is very cold (shown in dark purple), while water near the equator is very warm (shown in light blue). The differences in temperature cause water to change physical states. Extremely low temperatures like those found at the poles cause water to freeze into a solid such as a polar icecap, a glacier, or an iceberg. Extremely high temperatures like those found at the equator cause water to evaporate into a gas.
** Note: Some scientists place frozen water--glaciers, icecaps, and icebergs--in its own sphere called the "cryosphere." For the purpose of this course, however, frozen water will be included as part of the hydrosphere. The word "hydrosphere" will be used in reference to all water in Earth's system.
Biosphere - Living Things
The biosphere contains all the planet's living things. This sphere includes all of the microorganisms, plants, and animals of Earth.***
Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes. Deserts, grasslands, and tropical rainforests are three of the many types of biomes that exist within the biosphere.

A Food is broken down by catabolic pathways and converted to ATP, which is then used to fuel anabolic pathways.
What is Food chain?From microscopic algae to enormous blue whales, depends on food to thrive. Each food web represents a possible route for nutrients and energy to travel through the ecosystem.
As an illustration, grass makes its own sustenance from sunshine. A bunny consumes some grass. Eaten by a fox, the rabbit. When a fox dies, microbes decompose its remains and return it to the soil, where it feeds grass-like plants.
Grass is consumed by a wide variety of animals, and rabbits can also consume other plants besides grass. Foxes can consume a wide variety of animals and plants. These living organisms can all be found in different food chains.
Therefore, A Food is broken down by catabolic pathways and converted to ATP, which is then used to fuel anabolic pathways.

What is the difference between global effects and local effects.
Answer:
golbal means around the world but local means next to you
Answer:
A global effect generally affects, as the term implies, the world as a whole, or at least a major part of the world, while a local effect would be just in a distinctive area.
For example, if the world is heating up due to CO2 emissions, it heats up in an global effect, resulting in the median temperature rising in all areas of the world. However, the world heating up may only mean a drought in distinctive areas that are typically already leaning towards the drier side (local effect), while the others receive a greater than usual volume of water due to rising temperatures.

assume that life on Mars requires cell potential to be 100mV, and the extracellular concentrations of the three major species are following (mmol/L): Na : 145; K : 4; Cl- : 120. Choose one species and assume that other two probabilities are zero. Design the cell by calculating the intracellular concentration of the chosen species.
Answer:
Explanation:
From the information given:
The cell potential on mars E = + 100 mV
By using Goldman's equation:
[tex]E_m = \dfrac{RT}{zF}In \Big (\dfrac{P_K[K^+]_{out}+P_{Na}[Na^+]_{out}+P_{Cl}[Cl^-]_{out} }{P_K[K^+]_{in}+P_{Na}[Na^+]_{in}+ P_{Cl}[Cl^-]_{in}} \Big )[/tex]
Let's take a look at the impermeable cell with respect to two species;
and the two species be Na⁺ and Cl⁻
[tex]E_m = \dfrac{RT}{zF} In \dfrac{[K^+]_{out}}{[K^+]_{in}}[/tex]
where;
z = ionic charge on the species = + 1
F = faraday constant
∴
[tex]100 \times 10^{-3} = \Big (\dfrac{8.314 \times 298}{1\times 96485} \Big) \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)[/tex]
[tex]100 \times 10^{-3} = 0.0257 \Big ( \dfrac{4}{[K^+]_{in}} \Big)[/tex]
[tex]3.981= \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)[/tex]
[tex]exp ( 3.981) = \dfrac{4}{[K^+]_{in}} \\ \\ 53.57 = \dfrac{4}{[K^+]_{in}}[/tex]
[tex][K^+]_{in} = \dfrac{4}{53.57}[/tex]
[tex][K^+]_{in} = 0.0476[/tex]
For [Cl⁻]:
[tex]100 \times 10^{-3} = -0.0257 \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)[/tex]
[tex]-3.981 = \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)[/tex]
[tex]0.01867 = \dfrac{120}{[Cl^-]_{in}}[/tex]
[tex][Cl^-]_{in} = \dfrac{120}{0.01867}[/tex]
[tex][Cl^-]_{in} =6427.4[/tex]
For [Na⁺]:
[tex]100 \times 10^{-3} = 0.0257 \Big ( \dfrac{145}{[Na^+]_{in}} \Big)[/tex]
[tex]53.57= \Big ( \dfrac{145}{[Na^+]_{in}} \Big)[/tex]
[tex][Na^+]_{in}= 2.70[/tex]

The calcium ion passes easily through the membrane of one cell but
cannot cross the membrane of a second cell. Which part of the plasma
membrane allows this substance to cross? *
- Phosphate groups of the phospholipid bilayer allow the ions to cross.
- The fatty acid tails of the phospholipids allow the ions to cross.
- Protein channels in the plasma membrane allow the ions to cross.
- Carbohydrate groups on the membrane allow the ions to cross.
Answer:
Protein channels in the plasma membrane allow the ions to cross.
Protein channels which are present in the plasma membrane of the cell allow the ions to cross the plasma membrane. Thus, the correct option is C.
Channel protein is a kind of protein which is found embedded in the plasma membrane of the cell. Channel proteins function similar to a pore and it allows the diffusion of small ions and water molecules through them. Channel proteins are lipoproteins and these are synthesized in the rough endoplasmic reticulum of the cell near the nucleus.
Ion channels are the transmembrane proteins whose canonical function is the transport of ions and molecules across the plasma membrane to regulate cell membrane potential and also play an essential role in neural communication, nerve conduction, and muscle contraction in the body.
Therefore, the correct option is C.
