Explanation:
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]

Historically many ideas concerning cells have been examined leaving three to be incorporated into the cell theory which of the following is not part of the cell theory
Answer:all life form contains more than one cell
Explanation: thats the only question that's not true
Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
What is the significance of the theory behind the cell?Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.
Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

Ocean Salinity Increases
Ocean Salinity Decreases
Answer:
1. in ocean salinity increases
2. ocean salinity decreases
3.ocean salinity increases
4. ocean salinity decreases.
Explanation:
The salinity of the ocean is increased by the evaporation of ocean water and the formation of sea ice.
The salinity of the ocean is decreased by the melting of sea ice and entering a freshwater stream into the sea.
What is Ocean Salinity?Ocean salinity may be defined as the presence of the concentration of salts in the ocean. A Hydrometer is an instrument that determines the salinity of the ocean.
The addition of freshwater streams into the ocean and melting of ice reduce its salinity, as it makes the sea water less dense.
On contrary, the left two processes are opposite to above and thus are responsible for increasing the salinity of the ocean.
Therefore, it is well described above.

Animals get their energy by eating plants an animals. A living thing that needs to eat to obtain energy is called a?
Animals get their energy by eating plants an animal. A living thing that needs to eat to obtain energy is called a heterotroph.
Energy is defined as the property of matter that allows it to perform work or function.
Heterotrophs are organisms that obtain their energy by consuming other living things, such as plants or animals. They play an important role in the food chain, as they consume other living things and transfer energy up the chain.
For example: A herbivore (an animal that eats plants) is a heterotroph that obtains energy from the plants it consumes.
Therefore, heterotroph is a living thing that needs to eat to obtain energy.

The cholesterol associated with membranes
- helps stabilize the membrane at body temperature
- is attached to proteins and extends into the environment surrounding the cell
- both a and c
- is an abnormality resulting from a diet high in cholesterol
Answer:
b) It interferes with the movements of the fatty acid tails of the phospholipids.
Explanation:
Cholesterol has many important functions, including its role in membrane permeability, especially the cell membrane, and its role in metabolism. Cholesterol reduces the permeability of lipid membranes. ... Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids. Steroid molecule that makes membranes more fluid at low temps and more ordered at high temps.
- Flat, rigid, carbon rings interfere with the movement of phospholipids.
- Smaller and less amphipathic lipid that is only found in animals.
- Sandwiched between fatty acid tails of phospholipids.

Question 1 of 20
Which statement describes the difference between covalent bonds and Van
der Waals forces?
O A. Covalent bonds form from the attraction of positive ions and
freely moving electrons, while Van der Waals forces cause an
attraction between nonpolar molecules.
B. Covalent bonds form when there is an attraction between
nonpolar molecules, while Van der Waals forces cause two atoms
to share valence electrons.
C. Covalent bonds occur when two atoms share valence electrons,
while Van der Waals forces cause an attraction between positive
Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).
Answer:
Covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between nonpolar molecules.
