Why are antibiotics ineffective against viral infections

Answers

Antibiotics are ineffective against viruses because viruses do not have cells.
Antibiotics are commonly known and used to cure infections with bacteria, not viral infections. 

The reason to this is because viruses use their host cells to live as they are intracellular parasites. 

Antiviral drugs are usually used when there are viral infections. This prevents them from reproducing and improves the immunity.

In this excerpt from the poem "Learning to Read" by Frances Ellen Watkins Harper, what is the meaning of the word rising?And said there is no use trying,
Oh! Chloe, you're too late;
But as I was rising sixty,
I had no time to wait.

A. advancing

B. approaching

C. increasing

D. elevating

E. succeeding

Answers

The correct option is B.
To be rising means to be going up or to be increasing. Based on the way the word 'rising was used in the given excerpt, the word implies approaching. What the character in the poem was trying to say is that, since he is approaching his 60th birthday, he felt that time is going and he can not afford to waste anytime again, so he set out to accomplish his desires.

Answer: B. approaching.

Explanation:

  • The word approaching means to come near to a certain distance, time or anything else.
  • In the given excerpt, the word rising is placed before sixty which indicates the age.
  • In the given poem the character is saying "but as I was rising sixty" this means that the word rising points out to reaching the age of sixty and because the word approaching means to come near to something, it is the most appropriate answer.

Which equation correctly shows the reactants and products of photosynthesis? A C6H12O6 + 6CO2 --> 6O2 + 6H2O B C6H10O6 + 6O2 --> 6CO2 + 6H2O C 6O2 + 6H2O --> C6H10O6 + 6CO2 D 6CO2 + 6H2O --> C6H12O6 + 6O2

Answers

The right option is D 6CO2 + 6H2O --> C6H12O6 + 6O2

This equation shows that carbon dioxide and water are used with light energy to produce glucose sugar and oxygen gas.

Photosynthesis is a process by which plants and other autotrophs use energy from sunlight to produce nutrients from carbon dioxide and water. Plants absorb water through the roots, carbon dioxide from the air, and light energy from the Sun, to produce glucose and oxygen.


Final answer:

The correct equation for photosynthesis is 6CO2 + 6H2O --> C6H12O6 + 6O2. In this complex process, carbon dioxide and water are transformed into glucose and oxygen with the help of sunlight.

Explanation:

The correct equation that represents the reactants and products of photosynthesis is option D: 6CO2 + 6H2O --> C6H12O6 + 6O2. In this process, carbon dioxide (CO2) and water (H2O) are the reactants which, when exposed to sunlight, get transformed into glucose (C6H12O6) and oxygen (O2), which are the products. While the equation seems simple, it represents a complex multi-step process that plants use to convert light energy into chemical energy.

The blue-ringed octopus, shown below, utilizes a venom called tetrodotoxin as a defense mechanism.Tetrodotoxin binds to sodium channels and blocks the passage of sodium ions. Based on this information, which symptom would most likely occur in an organism exposed to tetodotoxin?

A.
decreased appetite due to the production of hormones that indicate fullness
B.
paralysis due to lack of action potentials to signal muscle tissue
C.
increased heart rate due to increased nerve impulses to the heart muscles
D.
blindness due to proteins in the eyes denaturing and losing functionality

Answers

Paralysis due to lack of action potentials to signal muscle tissue- this symptom most likely would occur in an organism exposed to tetrodotoxin.

The symptom occurs in an organism of tetrodotoxin:

Tetrodotoxin is a potent neurotoxin found in pufferfish, porcupinefish and blue-ringed octopus.

Has tetrodotoxin (TTX) in blue-ringed octopuses venom which causes pain and neurotoxic effects(paralysis) by inhabiting signal transduction by nerve cells through sodium channel blockade.

A dose of venom can shut down muscles such as those that keep you breathing and cause death within 30 minutes.

The correct answer is option B.

)B paralysis.    Tetrodotoxin works by inhibiting the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions into the neuron. This prevents the nervous system from carrying messages, eventually leading to paralysis
