Chloride ions cannot move out of cells by simple diffusion.

Biology
1 answer:
Goshia [24]2 years ago
6 0

Answer: Facilitated Diffusion.

Explanation:

Most substances use simple diffusion, move across a membrane because they are smaller and polar. But for chloride ions, that is not the case.

Chloride Ions are charged negatively, and since they are negatively charged, they cannon move across the membrane without help from something. Therefore, chloride ions move by facilitated diffusion using carrier proteins.

Facilitated Diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.

That explains how chloride ions can move in and out of cells.

Turtles Ahoy! (A real implementation of the scientific method) Did you ever wonder how baby sea turtles can run down into the oc
lord [1]

The scientific method is a research method that involves the question and problem definition, hypothesis formulation, goals, defining variables, collecting data and analysis, discussion, and conclusion.

<h3>What are the steps of the scientific method?</h3>

There are different steps to follow in a scientific method

  • Previous knowledge about the study object.
  • Definition and problem statement. The question for which there is no answer yet. A question the investigator wants to answer.
  • Goal especification. The goal is what the investigator wants to know.
  • Hypothesis formulation. The researcher hypothesizes in order to predict what is going on or what is expected to occur.
  • Experiment. Different variables influencing the proyect are considered. Data collection and analysis stages. This step involves testing the observations.
  • Results
  • Discussion and hypothesis verification. This step involves the deriving of the working hypothesis.
  • Conclusions.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It must be objective. Usually, it is written in the present time.

It is a claim of how it works a relationship between two or more variables. There must be a logical relationship between the involved variables.

<h3>What are dependent and independent variables?</h3>

When conducting an experiment, we must always consider the involved variables.

  • Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results. This variable is not affected by any other one but influences or causes a reaction in other variables.

  • The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one. Its response might be either directly proportional or inversely proportional to the change in the independent variable.

In the exposed example,

1. <em>Circle and label the question that is going to be investigated</em>.

How can sea turtles orientate into the ocean after hatching, paddle thousands of miles across the North Atlantic, and find their way back years later to the same beach they were born?

2. <em>What is the hypothesis</em>?

Turtles use Earth's magnetic fields and waves to orientate themselves in the water and on the ground.

3. <em>What is the independent variable</em>?

The magnetic field orientation.

4. <em>What is the dependent variable</em>?

Direction in which the turtles swim.

5. <em>What are the constants</em>?

Large glass tank filled with water and total darkness.

6. <em>Describe the data and analysis</em>.

Data,

  • Under normal magnetic field, the turtles swam towards the notheast.
  • Under reversed magnetic field, the turtles swam toward the southwest.

Analysis,

Turtles follow magnetic north and east, even when the magnetic field orientation is reversed.

7. <em>What is the conclusion</em>?​

The hypothesis is accepted. Turtles use Earth's magnetic fields to orientate themselved moving between the magnetic north and east.

How does a prokaryotic cell such as bacteria differ from eukaryotic cells?​
LenKa [72]

Answer:

The main difference is that EUKARYOTIC cells <em><u>have</u></em> a nucleus while a PROKARYOTIC cell <em><u>does not</u></em>. Instead, prokaryotes have free floating genetic material.

Explanation:

To help you remember this distinction:

EU = YES eukaryotes <em><u>HAVE</u></em> a nucleus.

PRO = NO prokaryotes <em><u>DO NOT</u></em> have a nucleus.

I hope this helps and good luck with your assignment.

Solid sodium reacts with liquid water to form hydrogen gas according to the equation 2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) Wha
lana66690 [7]

Answer: 21850.42mmHg or 28.78atm

Explanation: From the equation of the reaction, 2 moles of sodium reacts with 2 moles of water to produce 2 moles of NaoH and 1 mole of hydrogen gas at s.t.p.

molar volume of gas at s.t.p. = 22.4dm^3,

standard temperature = 0°C or 273K,

standard pressure = 760mmHg or 1atm,

molar mass of Na = 23g;

volume of the container= 20L or 20dm^3

From the equation, 2 moles or 46g of Na produces i mole or 22.4 dm^3 of hydrogen.

Therefore, 1kg or 1000g of Na will produce 22.4 * 1000/(46)= 486dm^3 of hydrogen.

To find the pressure of the gas produced, the formula P1V1/T1 = P2V2/T2

P1= 760mmHg, T1= 273K, V1 (initial volume of gas)= 486dm^3, T2=50.0°C or 50+273K= 323K, V2( final volume of gas= volume of vessel)=20dm^3  P2=?

P1= P1V1*T2/(V2T1)= 760mmHg * 323/(273)= 21850.42mmHg or 1atm*21850.42/760= 28.78atm
