What is not utilized to culture viruses?

Biology
2 answers:
Alina [70]3 years ago
7 0

Explanation:

Viruses can be made to grow within a living organism or outside a living organism in cells in unnatural environments like agar plate, cell culture flask, test tube and so on. This act is what is referred to as Vital culture.

Animal virus cultivation is very vital or necessary for:

***The production or development of vaccines

***Diagnosis of viruses which are pathogenic in nature.

***Carrying out research studies on virology

Some of the instruments that come in handy during viral culture include:

a. Auto-destruct syringes for specimen colleci.

b. Bijou bottle with screw cap used as a culture medium holder.

c.Mc Cartney's bottle for simultaneous solid and liquid cultures.

d. Platinum wire loop used to inoculate test samples into culture medium.

e. Biosafety cabinet used to work sterile

f. Haemagglutination plate for viral culture detection

g. Specimen dish used for holding specimens

h. Agar plate or petri dish which acts as a form of supporting container to hold the culture medium

i. Tissue culture bottles used to grow and keep alive cells or tissues from living organisms.

j. Pre-sterilized disposable container which is used for collection of specimen etc

Explanation:

Cell culture is the process by which cells, whether prokaryotic or eukaryotic cells, can be grown under controlled conditions. In practice, the term "cell culture" is normally used in reference to the culture of cells isolated from multicellular eukaryotes, especially animal cells. The historical and methodological development of cell culture is intimately linked to the cultivar peptides of tissue culture and organ culture.

Animal cell culture began to be a routine laboratory technique during the 50,1 years but the concept of keeping living cell lines separate from the tissue of origin was discovered in the 19th century.

QveST [7]

Answer:

The correct option is a decomposers

Explanation:

Decomposers can be described as organisms which feed on dead and decaying material. These organisms break down molecules and use them as a source of food. Among the options mentioned, the option of decomposers is the only one which is applicable to fungus like protists and is unique to it. On the other hand, Plant like protists make their own food by the process of photosynthesis.  Hence, option A is correct.

Correctly identify each of these definitions or examples as either depolarization or hyperpolarization of the plasma membrane. 1
natulia [17]

Answer:

  1. hyperpolarization
  2. depolarization
  3. hyperpolarization
  4. depolarization
  5. hyperpolarization
  6. depolarization
  7. depolarization

Explanation:

The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. <em>This is known as depolarization.</em>

The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. <em>This is called repolarization. </em>

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of <em>hyperpolarization</em> that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

<em>Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)</em>

<em>Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).</em>

I hope you find this information useful and interesting! Good luck!<em>       </em>

What caused the uplift of the Himalayas?
andrew11 [14]

The ongoing active collision of the Indian and Eurasian continental plates challenges one hypothesis for plate motion which relies on subduction. ... The collision and associated decrease in the rate of plate movement are interpreted to mark the beginning of the rapid uplift of the Himalayas.
