The right answers are: Phospholipids and protein. And Selective membrane.

(It is the cell wall which is composed by cellulose and increase strength to the cell)

Phospholipids are the essential constituents of cell membranes where, with cholesterol molecules, they are organized into a lipid bilayer in which the hydrophobic tails are oriented towards the interior of the structure whereas the polar heads form the two surfaces of the bilayer.

Biological membranes are a selective barrier between the inside and the outside of a cell or a cell compartment (organelle). They, therefore, have the property of selective permeability, which makes it possible to control the entry and the exit of the different molecules and ions between the external and the internal environment. This allows each cell organelle, but also the entire cell to have a composition different from the external one.

Answer;

-Phospholipids and protein

Explanation;

-The plasma membrane is composed of a phospholipid bilayer arranged back-to-back. It is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.

- The membrane is an extremely thin layer of lipids and protein that forms outer boundary of every cell, It controls movement of molecules between the cell and its environment, Participates in joining cells to form tissues and organs and also plays important role in the ability of a cell to respond to changes in the cell's environment.

<u>__________________________________________________________</u>

Q1: <em>What is an electromagnet?</em>

A1: <em>According to Microsoft Dictionary, a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.</em>

<u>__________________________________________________________</u>

Q2: <em>What are the parts of an electromagnet?</em>

A2: <em>According to Sciencing, Significance. Electromagnets are a vital part of everyday life.</em>

<em>Operation. Electromagnets behave the same way as regular magnets.</em>

<em>Construction. The basic components of an electromagnet are a wire and a power source.</em>

<em>Special Types of Electromagnets. Solenoids are electromagnets that are in the form of a helix. </em>

<u>__________________________________________________________</u>

Q3: <em>How is an electromagnet useful when compared to a permanent magnet?</em>

A3: <em>According to Toppr, The main advantage of an electromagnet over a permanent magnet is that we can quickly change the magnetic field by controlling the amount of electric current in the winding. The magnetic field created by an electromagnet is proportional to both the number of turns in the winding and the current in the wire.</em>

One group of medications used to treat HIV infections is reverse transcriptase inhibitors. There are two types of these medicati
Nezavi [6.7K]

Answer:

c) Nucleoside reverse transcriptase inhibitors may interfere with DNA replication by the host, not just by the virus.

Explanation:

A drug that targets the structures or processes specific to the pathogen or microbe has fewer side effects than the drugs that target the more general structures and processes exhibited by both the pathogen and host cells.

According to the given information, the nucleoside reverse transcriptase inhibitors resemble thymine and terminate the process of DNA replication. Thymine base is also one of the nitrogenous bases present in the human cells and other organisms. Therefore, the nucleoside reverse transcriptase inhibitors would terminate the process of DNA replication in both the virus and the host organism.

On the other hand, the non-nucleoside reverse transcriptase inhibitors specifically target the reverse transcriptase enzyme that is not present in host organisms. Therefore, the non-nucleoside reverse transcriptase inhibitors have fewer side effects than the nucleoside reverse transcriptase inhibitors.

Would an enzyme work in a different environment that is used to?
Mariana [72]

Answer:

Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction.

Adults who are on their feet alot for work will often soak their swollen ankles in a pail of hot water with Epsom salt dissolved
Tanya [424]

The type of solution formed is hypertonic.

<h3>What are hypertonic solutions?</h3>

Hypertonic solutions are solutions with higher dissolved solutes as compared to the sap of the cells suspended in them.

Epsom salt is made up largely of magnesium sulfate. Thus, a solution formed by dissolving Epsom salt is water will have more magnesium in it than the cells of the part of the body soaked in it.  

Hence, such a solution is hypertonic.
