6 0

Facilitated diffusion is necessary when cell membranes prevents a substance from diffusing on its own.

Facilitated diffusion is a type of passive transport that involves movement of solute materials down the concentration gradient.

<h2>Further Explanation;</h2><h3>Transport in living organisms</h3>
  • Plants and animals use various processes to transport materials from one point to another.
  • There are classified as either passive transport or active transport.
<h3>Passive transport</h3>
  • It is a type of transport that does not involve the use of energy to aid movement of substances in living organisms.
  • Passive transport involves free movement of substances and through special types of transporters or carriers.
  • Types of passive transport includes; simple diffusion, facilitated diffusion, osmosis, and mass flow among others.
<h3>Active transport  </h3>
  • It is a type of transport in living organisms that involves movement of substances against a concentration gradient and involves use of energy in form of ATP to aid transport of substances.
<h3>Types of passive transport</h3><h3>Facilitated diffusion</h3>
  • Facilitated diffusion is a type of passive transport which involves the diffusion of solutes by use of transport proteins in the plasma membrane.
  • Facilitated diffusion uses transport proteins to transport solutes down their concentration gradient.
<h3>Osmosis  </h3>
  • Osmosis is a special diffusion that involves the movement of water molecules from a region where they are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.
  • It may also refer to the movement of water molecules from a region of low particle concentration to a region of a high particle concentration.
<h3>Diffusion  </h3>
  • Diffusion is a type of passive transport that involves movement of particles from a region of high concentration to a region of low concentration.
  • Diffusion involves movement of molecules of substances other than water.

You have isolated a mutant strain of Bacillus subtilis (which you designate wimP) whose endospores can be killed by boiling wate
Ivanshal [37]

Answer:

The correct answer is option e. "higher water content".

Explanation:

One of the features that make endospores resistant to high heat in its low water content. The cortex of the endospore osmotically removes the water from the interior of the endospore, condition that protects them from heat and radiation. The wimP spores that can be killed by boiling water most likely have a higher water content in comparison to wild-type endospore. This explains why wimP spores are susceptible to be killed with the heat generated by boiling water.

Surgery is performed on a client. the postoperative arterial blood gas values are ph 7.32, pco 2 53 mm hg, and hco 3 25 meq/l (2
Elden [556K]
<span>The answer to this question would be: Ask the client to cough forcefully and take deep breaths.

The arterial blood gas result shown that the patient blood pH is a bit acidic. The pressure of carbon dioxide is a bit elevated that show the problem is in the respiratory organ. The patient that getting surgical is intubated and sedated so there might be fluid build up in the lungs but the cough reflex is decreased. Coughing can help clear the lungs.

PLSSSSS HELPPPP I BEGGGG !!!1.) Identify the five steps of the science process make sure to include all steps in detail. 2.) Exp
Ne4ueva [31]

Answer:

hii there

how are you?

here's your answer

Explanation:

1 )

The five steps of the scientific method

Step 1: Ask a question or identify a problem. A scientist learns about the universe by observing

Step 2: Background research.

Step 3: Form a hypothesis.

Step 4: Experiment and observe.

Step 5: Draw a conclusion.

2 ) Matter is the stuff that makes up the universe everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Both atoms and molecules are held together by a form of potential energy called chemical energy.

3 ) Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the state of matter. The three fundamental phases of matter are solid, liquid, and gas.

hope it helps you dear
