Hope it HELPS U

To PREVENT the spread of COMMUNICABLE DISEASE...

1) one should have to wear mouth mask.

2) one should not have to SPIT any where because spiting spreads bacterial infections.

3) one should have to put there hands on mouth while coughing.

I HOPE IT HELPS YOU....
THANKS.

HI Brainly USER....

Archeal cell wall have Pseudopeptidoglycanwhich is COMPOSED of mainly two COMPONENTS which are:

1.N-acetylglucosamine

2.N-acetyltalosaminuronic acid

hope U find this ans helpful.

All the best.

Here is the answer my friend hope it helps
When ANIMALS cell is put in a solution it will BURST
But plant cells do not burst as they have a cell WALL which REGULATES the turgar pressure.

Microorganisms can survive harsest CONDITIONS RANGING from extreme cold to extreme hot.
They have protective layer CALLED cell wall.
Some can even live without oxygen.
tardigrade can even live in SPACE!!

Aerobic respirationrequires oxygen in order to generate ENERGY molecule ATP, where as an anaerobic respiration SYNTHESIZE ATP by using the ELECTRON transport chain, with inorganic molecules other than oxygen.

An INFECTIOUS disease transfer to ONE person to another person.

Ebola,common COLD are the communicable diseases..

Although DNA stores the information for protein synthesis and RNA carries out the instructions encoded in DNA, most biological activities are carried out by proteins. The accurate synthesis of proteins thus is critical to the proper functioning of cells and organisms. We saw in Chapter 3 that the linear order of amino acids in each protein determines its three-dimensional structure and activity. For this reason, assembly of amino acids in their correct order, as encoded in DNA, is the key to production of functional proteins.

Three kinds of RNA molecules PERFORM different but cooperative functions in protein synthesis (Figure 4-20):



Figure 4-20

The three roles of RNA in protein synthesis. Messenger RNA (mRNA) is translated into protein by the joint action of transfer RNA (tRNA) and the ribosome, which is composed of numerous proteins and two major ribosomal RNA (rRNA) molecules. [Adapted from (more...)

1.

Messenger RNA (mRNA) carries the GENETIC information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid.

2.

Transfer RNA (tRNA) is the key to deciphering the code words in mRNA. Each type of amino acid has its own type of tRNA, which binds it and carries it to the growing end of a polypeptide chain if the next code word on mRNA calls for it. The correct tRNA with its ATTACHED amino acid is selected at each step because each specific tRNA molecule contains a three-base sequence that can base-pair with its complementary code word in the mRNA.

3.

Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex STRUCTURES, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis. Ribosomes are composed of a large and small subunit, each of which contains its own rRNA molecule or molecules.

Translation is the whole process by which the base sequence of an mRNA is used to order and to join the amino acids in a protein. The three types of RNAparticipate in this essential protein-synthesizing pathway in all cells; in fact, the development of the three DISTINCT functions of RNA was probably the molecular key to the origin of life. How each RNA carries out its specific task is discussed in this section, while the biochemical events in protein synthesis and the required protein factors are described in the final section of the ch

There are several reasons NERVE impulses only travel in ONE direction. The most important is synaptic transport. In ORDER for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. ... When you GET a nerve firing, you have probably heard that it is an electricalimpulse that carries the SIGNA

Both mitosis and meiosis are associated with cytokinesis. The END result of both are daughter cells produced from a parent cell. The fundamental sequence of EVENTS in mitosis is the same as in meiosis (in meiosis it happens twice). Both processes include the breakdown of the NUCLEAR MEMBRANE, the separation of genetic MATERIAL into two groups, followed by cell division and the reformation of the nuclear membrane in each cells. The processes differ in two fundamental. Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.

Plant KINGDOM is divided into 3 types:1thallophytes 2.bryophytes 3.pteridophytes .
1.thallophyes have a thallllus like STRUCTURE and they are commonly in algaes.
2.bryophytes are known as amphibians of plant kingdom.
3.pteridophytes are USED only for decorative PURPOSES

Plasma is the clear, straw-colored LIQUID PORTION of blood that remains after red blood cells, white blood cells, PLATELETS and other CELLULAR components are removed. It is the single largest component of human blood, comprising about 55 percent, and contains water, salts, ENZYMES, antibodies and other proteins.

Antibiotics are medicines USED to prevent and TREAT bacterial infections. ANTIBIOTIC resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans, BECOME antibiotic resistant. These bacteria may then infect humans and are harder to treat than non-resistant bacteria. Antimicrobial resistance is a broader term, encompassing resistance to drugs to treat infections caused by other MICROBES as well, such as parasites (e.g. malaria), viruses (e.g. HIV) and fungi (e.g. Candida).

Chloroplast

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.

Chloroplasts absorb SUNLIGHT and use it in conjunction with water and carbon DIOXIDE gas to produce food for the plant.

Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Chloroplasts are one of the many unique organelles in the BODY, and are generally considered to have originated as endosymbiotic cyanobacteria.

In this respect they are similar to mitochondria, but are found only in PLANTS and protista.

Both organelles are surrounded by a double celled composite membrane with an intermembrane space; both have their own DNA and are involved in energy metabolism; and both have reticulations, or many infoldings, filling their inner spaces.

No DNA POLYMERASE exists to synthesize DNA in the 3′ to 5′ direction, so copying of the lagging strand is discontinuous—that is, SHORT strands of DNAare made and subsequently matured by joining them together. An RNA PRIMER, which is made by primase, initiates each of these small pieces ofDNA.
