<h2>CRISPR/Cas9</h2>

Explanation:

CRISPR can be used to reintroduce dystrophin back into the KO mouse

  • CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats and is used to for gene editing
  • CRISPR/Cas-mediated genome editing has been shown to permanently correct DMD mutations and restore dystrophin function in mouse models
  • Germline editing by injecting zygotes with CRISPR/Cas9 editing component was first done in mdx mice by correcting the mutated exon 23
  • Postnatal editing of mdx mice was then achieved using recombinant adeno-associated virus to deliver CRISPR/Cas9 genome editing components and correct the dystrophin gene by skipping or deleting the mutated exon 23 in vivo
  • Germline and postnatal CRISPR/Cas9 editing approaches both successfully restored dystrophin function in the mice and same technique can be used for KO mouse model

Explain how a starfish's body plan and anatomy enables invertebrate to perform the essential functions it needs to survive.
Vladimir [108]
Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies. 
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.

Furkat [3]

Answer: Although the Moon appears to shine, it does not emit light. Instead, we can see the Moon because it is lit up by the Sun.

Explanation:

The part of the Moon that is both sunlit and facing Earth is called the Moon's phase.

As the Moon orbits Earth, the Moon's phase changes. The model below shows the Moon's phase at eight positions in its orbit. The smaller moons closer to Earth show where sunlight hits the Moon. The larger moons farther from Earth show how the Moon will look during that phase.
