Transformation is a useful technique for making genetically modified bacteria in the laboratory. There have been efforts to tran

sform Archaea, but it has been more difficult than transforming Bacteria. One reason that it has been difficult is that Archaea lack a peptidoglycan cell wall. Why does that affect the ability of researchers to develop techniques to transform them

<h2>Transforming Bacteria</h2>

Explanation:

  • Archaea and bacteria are different in the qualities of the cell wall and in the lipid composition of their cell membranes
  • <em>Bacterial cell dividers contain peptidoglycan</em>
  • Archaean cell wall don't have peptidoglycan, yet they may have <em>, polysaccharides, glycoproteins, or protein-based cell dividers </em>
  • Bacterial cell walls are made of peptidoglycan (likewise called murein), which is produced using polysaccharide chains cross-connected by abnormal peptides containing D-amino acids

Answer:

Mutualism

Explanation:

In biology, the term <em>symbiosis </em>refers to close and often long-term interactions between organisms that belong to different species. There are three main types of symbiotic relationships:

  • mutualism - both organisms benefit from their relationship
  • commensalism - one organism benefits, while the other doesn't benefit or suffer any harm
  • parasitism - one organism causes harm to the other

In the given scenario, both the bird and plant benefit from their relationship. The bird gets food, while the plant reproduces more easily. This is why their relationship is an example of mutualism.

What is the study of fish known as in biology?​
klio [65]

Answer:

The study of fish is called Ichthyology.

Explanation:

Fish specimens are identified in the field by ichthyologists. Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution).

Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution). Large reference collections of preserved specimens are kept in museums as a permanent resource for present-day researchers as well as for future ones.

WILL BRAINLIST CORRECT ANSWER PLATO
Dmitrij [34]

Answer:

I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance.

Explanation:

The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense).

The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).

And the third one would be codominance because the traits of red color and white color are equally dominant.

Please help I will give BRAINLIEST face the earth
Oxana [17]

Answer:

It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.

Explanation:

Hope this helps you a lot my boo!
