Which best describes the role of immunosuppressants in transplant surgeries?

Answers

Immunosuppressants, by it's name itself, suppresses or inhibits the immune system for functioning in a certain amount of time. It is administered usually during transplant surgeries, so that the new cells of the organ does not get killed by the recipient's immune system.

True or False? As the energy is transferred from producers to consumers, energy is gained.

Answers

Answer:

False.

Explanation:

The food chain may be defined as the sequential tropic levels in which the organism eat other organisms and itself being eaten by other organism. Food chain do not exist in nature.

According to the 10% energy law, the energy is lost from one tropic level to the another tropic level. The 10% energy is available to the next tropic level and the remaining amount of energy is lost as heat. No energy gain occurs as the transfer of energy takes place from the producer to consumer.

Thus, the answer is false.
false because it's using energy to do the work. one way to gain energy is by making it. but yet again this is my thought but like i said it's false. 

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

Match each microorganism with the correct description. 1. single-celled organism with a nucleus that feeds on other microorganisms bacteria 2. tiny bundle of genetic material that can cause disease rickettsiae 3. multicellular or unicellular organism with no roots or chlorophyll fungi 4. unicellular organisms in Monera kingdom virus 5. type of bacteria that grows in living cells protozoa

Answers

1. Protozoa are single celled, eukaryotic organisms that exhibit animal-like behaviour.2. Viruses consists only of genetic material and a protein coat, and they are known to cause a wide variety of diseases such as AIDS.3. Fungi have characteristics similar to plants, but they do not have root systems like plants do and they also do not rely on chlorophyll to photosynthesize.4. Bacteria make up this category.5. Rickettsiae is a genus of bacteria that are intracellular parasites.

Which BEST describes the orbit of the Moon around Earth?Select one:
a. circular with a period of about one month
b. circular with a period of about one week
c. elliptical with a period of about one month
d. elliptical with a period of about one week

Answers

The statement that best describes the moon's orbit around the Earth is c. elliptical with a period of about one month. Although its orbit is elliptical, the moon's orbit can be described as nearly circular because it has an eccentricity of 0.05. Moreover, it takes around 27.322 days for it to orbit around the Earth once.
