assume that life on Mars requires cell potential to be 100mV, and the extracellular concentrations of the three major species ar

svetlana [45]

Answer:

Explanation:

From the information given:

The cell potential on mars E = + 100 mV

By using Goldman's equation:

$E_m = \dfrac{RT}{zF}In \Big (\dfrac{P_K[K^+]_{out}+P_{Na}[Na^+]_{out}+P_{Cl}[Cl^-]_{out} }{P_K[K^+]_{in}+P_{Na}[Na^+]_{in}+ P_{Cl}[Cl^-]_{in}} \Big )$

Let's take a look at the impermeable cell with respect to two species;

and the two species be Na⁺ and Cl⁻

$E_m = \dfrac{RT}{zF} In \dfrac{[K^+]_{out}}{[K^+]_{in}}$

where;

z = ionic charge on the species = + 1

F = faraday constant

∴

$100 \times 10^{-3} = \Big (\dfrac{8.314 \times 298}{1\times 96485} \Big) \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)$

$100 \times 10^{-3} = 0.0257 \Big ( \dfrac{4}{[K^+]_{in}} \Big)$

$3.981= \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)$

$exp ( 3.981) = \dfrac{4}{[K^+]_{in}} \\ \\ 53.57 = \dfrac{4}{[K^+]_{in}}$

$[K^+]_{in} = \dfrac{4}{53.57}$

$[K^+]_{in} = 0.0476$

For [Cl⁻]:

$100 \times 10^{-3} = -0.0257 \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)$

$-3.981 = \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)$

$0.01867 = \dfrac{120}{[Cl^-]_{in}}$

$[Cl^-]_{in} = \dfrac{120}{0.01867}$

$[Cl^-]_{in} =6427.4$

For [Na⁺]:

$100 \times 10^{-3} = 0.0257 \Big ( \dfrac{145}{[Na^+]_{in}} \Big)$

$53.57= \Big ( \dfrac{145}{[Na^+]_{in}} \Big)$

$[Na^+]_{in}= 2.70$

In the context of nutritional status assessment, height, body weight, and body composition are frequently used?

Harman [31]

Dietary assessors in the context of nutritional status assessment ,height , body weight and body composition are frequently used.It is important not only in study of associations between diet and health related outcomes but also for nutritional status of patients in clinical settings.

Anthropometry is the measurement of physical dimension such as height , body weight and composition of human body to provide information related to individuals nutritional status.

It involves the collection of information on food and drink consumed over specific time that is coded and processed to compute intakes of energy and nutrients or others dietary constituents using food composition tables.

When water is distilled, any solutes dissolved in the water are left behind. Is distilled water hypertonic or hypotonic compared

Illusion [34]

Answer:

Hypotonic

Explanation:

Tap water contains a lot of solutes and ions that are absent in distilled water. The solution that has more solutes (more dissolved solids) will be the hypertonic solution.

Here, distilled water has no solutes, making it hypotonic.

In the hypothesis that C. stellatus (a species of barnacle) is competitively excluded from the lower intertidal zone by B. balan

lord [1]

<h2>Competitive exclusion principle.</h2>

Explanation:

The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.

All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.

Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.

B. balanoides can use a wider range of resources than C. stellatus because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.
