Which is the difference between an antibiotic and an antiviral?
Answer:
There are no options in this question, the options are as follows:
A. Antibiotics build up immunity, and antivirals increase white blood cells.
B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.
C. Antibiotics are in liquid form, and antivirals are in mist form.
D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.
The answer is D
Explanation:
Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.
According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.
Answer:
A. Antibiotics build up immunity, and antivirals increase white blood cells.

define the term (1)semi-permeable membrane (2) osmosis tell the answer i will mark u as brainlist
Answer:
a)the outermost part of an animal cell that selectively allows things to pass through and come out.
b) the passing of water molecules from higher conc. to lower conc.
Answer:
(a) Semi-permeable membrane:
A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.
(b) Osmosis:
The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.
When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.
Question 7 of 10
A cell membrane is very specific about what it allows across. How does this
help the cell?
O A. Transport proteins allow only enzymes to pass through the
membrane.
O B. It is better for the cell if most molecules are prevented from
entering.
O C. The cell works better when it contains fewer proteins.
D. It helps the cell absorb as many different molecules as possible.
Answer:
The answer is D
Explanation:
As the cell is mostly dependant on ingested materials so this will help the cell to grow and perform other important activities in the cell
Write down the functions of
1.microtubules
2.tripletsof microtubules
Answer:
Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility
Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.
Hope it helps :)
Answer:
Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).
triplet microtubules are linked together to make the walls of the cylinder.

Do you agree or disagree that homologous chromosomes are found in gametes. Explain
Answer:
Disagree. Homologous chromosomes are pairs of similar chromosomes. Because gametes are haploid, they contain only one set of chromosomes. Thus, homologous chromosomes are not normally found in gametes.
Explanation:
how are hydrogen bond similar to iconic bonds?
Explanation:
Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. ... This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation. The attraction between these charges hold the atoms together in an ionic bond.
Hydrogen bonds are inter-molecular bonds. The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges

Which of the following can be inferred from the genetic code?
A.All organisms have a common biochemical evolutionary origin.
B.Organisms can live without genetic code.
C.Four nucleotides.
D.Four nucleosides.
Answer:
A. All organisms have a common biochemical evolutionary origin.
Explanation:
Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.
One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.
