How do you remove bacterial contamination from cell culture?

Answers

Answer 1

Bacterial contamination can be removed from cell culture using several methods. These include proper aseptic technique, filtration, antibiotics, and centrifugation.

The first and most important method for removing bacterial contamination is ensuring proper aseptic technique. This includes using sterile equipment and materials, wearing gloves and masks, and cleaning all surfaces and equipment with a disinfectant. Additionally, it is important to use aseptic techniques when transferring media and culturing cells. Following these basic techniques can help to reduce the risk of bacterial contamination from the start.

In the event of contamination, several other methods can be used to remove bacteria from culture. One of the most common methods is filtration. This involves passing the culture through a filter to remove the bacteria. This method is effective but may be time-consuming, depending on the size of the culture and the particle size of the bacteria.

Another method for removing bacteria from cell culture is antibiotics. Antibiotics can be added directly to the culture to kill the bacteria, though this may not be ideal in some cases due to the potential to affect the cells. Additionally, antibiotics may not be effective against certain types of bacteria. Therefore, it is important to select an appropriate antibiotic based on the type of bacteria present.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.​

Answers

Answer:

By using carbon-14 in the experiment in order to prove the statement.

Explanation:

Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

Answer:

Isotonic Solution

Explanation:

There are commonly three types of solutions:

Hypertonic solution = the concentration of solute is greater than in the cellHypotonic solution = the concentration of solute is less than in the cellIsotonic solution= the concentration of solution and cell is same.

So, if the cell was in any other solution, it would have been burst or it would shrink. but nothing changed because it was in a solution where outside environment is similar to the internal environment

If two-hybrid Ff rabbits mate, what will the offspring look like?

Answers

Answer:

25% FF - homogenous dominant

50% Ff - heterogenous

Explanation:

When two-hybrid Ff rabbits mate, then the offspring look like

25% FF - homogenous dominant25% ff - homogeneous recessive50% Ff - heterogenous.

What is Mating?

For the goal of sexual reproduction, opposite-sex or hermaphrodite organisms team together during mating. Two gametes join together during fertilisation. When two sexually reproducing creatures join their sex organs, internal fertilizations and insemination take place.

Punnett Square situations with two hybrid parents marrying are frequent. The heterozygous hybrid parents possess a single allele (A and a, Dominant and Recessive). There are four genotype outcomes that can happen if two hybrid parents mate.

Thus, when two-hybrid Ff rabbits mate, then the offspring look like

vocabulary words to use in response: dominant allele, recessive allele, , heterozygous, genotype, phenotype

Answers

Answer:

No.

Explanation:

Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.

No.
