Which of the following structures are used by prokaryotes for attaching to surfaces?a. capsule
d. nucleoid

Answers

The structure used by prokaryotes for attaching to surfaces is Capsule.

RoleofCapsuleinprokaryotes

Capsules are known to be the sticky outermost layer made up of polysaccharides.

Their role in prokaryotes include:

  • Aid prokaryotes to cling to each other.
  • Allows prokaryotes to attach to surfaces in their environment
  • Helps in preventing prokaryotic cell dehydration.

Therefore, the structure used by prokaryotes to attach to surfaces is the capsule.

capsule- This additional outer covering protects the cell and helps to adhere to surfaces and nutrients.

One advantage of having a cloned flock

Answers

Answer:

Producing transgenic animals has practical advantages, such as using less than half of experimental animals for the production of an envelope.

Explanation:

Currently it is only possible to add genes, the transgenic sheep that exist are found to produce human proteins. However, it is convenient for some proteins to remove endogenous proteins from milk. For example, for human serum albumin.

There is a high demand for some human proteins for the treatment of various diseases. Small quantities can be produced in cell cultures but the cost is very high. Higher amounts can be made by bacteria or yeasts, but proteins are difficult to purify and that is why some of the advantages of having transgenic animals is the amount of protein produced.

it eliminates certain genetic diseases or bad traits for the flock.

Which could result from a person who does not finish the prescribed amount of antibiotics for an infection?

Answers

Ans. Antibiotic resistant bacteria.

If someone fails to complete the course of antibiotics for an infection, some of infection causing bacteria may survive (having a greater resistance for those antibiotics). It will lead to bacterial population in afflicted patient, with a higher resistance than normal ones.

When these resistant bacteria reproduce, infection caused by their progeny would not be treatable with same old antibiotics.

Melissa is studying a Gram-stained slide of curd bacteria. She sees many rod-shaped, violet-colored bacteria. What type of bacteria are they?

Answers

Answer:

By the observation, the rod shape violet-colored bacteria could be a Gram-positive bacillus which is Lactobacillus spp.  in curd.

Explanation:

Gram-stain is a staining method to isolate and study the Gram-positive or Gram-negative bacteria with the help of the crystal violet dye. Crystal violet dye stains both Gram-positive and Gram-negative bacteria in purple stain. After decolorization, Gram-negative bacteria appears to be pink in color, however,Gram-positive bacteria remain purple.

According to bacteria structure, they term as bacillus (rod), strepto (clusters or threads) or Diplo (in pairs).

Thus, according to the observation, the rod shape violet colored bacteria are Gram-positive bacillus which is Lactobacillus spp. in curd.
Rod shaped = bacilli
Purple =Gram positive
The bacteria is Lactobacillus
