Technically, X-ray crystallography, which is like an unfocused electron microscope, was first used to see DNA structure. Scientists today use more refined electron microscopes for researching DNA and its structure

Explanation:

The electron microscope is a kind of microscope that uses a beam of electrons to produce an image of the specimen. It is acceptable of important special magnifications and has a greater resolving power than a light microscope, providing it to see much smaller objects in precise detail.

PLEASE HELP!!Why might humans not have widespread regeneration abilities?
aev [14]

Answer:

Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.

The pubic symphysis connects the two hip bones anteriorly and provides a little movement during childbirth. Choose the most appr
My name is Ann [436]

Answer:

The most appropriate tissue to join the pubic symphysis -that provides resistance to pressure and stretch during childbirth- is fibrocartilage.

Explanation:

Options for this question are:

  • <em>A. Fibrocartilage.</em>
  • <em>B. Elastic cartlage.</em>
  • <em>C. Bone.</em>
  • <em>D. Hyaline cartilage.</em>

Fibrocartilage is made up of dense connective tissue rich in type I collagen fibers, hyaluronic acid and proteoglycans, which give it resistance to stretching and pressure.

Some ligaments are formed by fibrocartilage, in addition to the intervertebral discs and the junction of the pubic symphysis, allowing a certain degree of mobility to the associated structures due to their semi-elastic properties.

Hyaline cartilage, also made up of connective tissue, is less resistant than fibrocartilage.

Bone cannot form this junction, because it would not allow the relative mobility of the joint.

The elastic cartilage allows for stretching but not the strength needed to join the pubic symphysis.
