Answer:
The thorns on a rose bush.
The white coat of a snowshoe hare.
The speed of a gazelle.
Explanation:
Defense mechanisms are the adaptations and modifications in a living organism to counterattack or provide a defense in response. Some modification in the plant and the animals helps them to provide a counterattack to save themselves from the attack. The defensive function of the thorns in the roses helps them from being eaten or crushed. Snowshoe hares have furry feet that are large. The white fur helps them to camouflage during winter in the snow and be safe from the predators. Gazelle is an antelope found in South Africa that is able to make long jumps and make sharp turns while running and saving itself from the predators.
Cell division, also called mitosis , occurs in multicellular organisms to create tissues, organs and organ systems.
Answer:
It has incomparable advantages over other gene editing tools.
Explanation:
For example, the CRISPR-Cas9 system has more target sites than ZFNs and TALENs, and Cas9 has many variants that can be used in a variety of studies. Moreover, the system is extremely easy to use and can be executed in almost any laboratory.
The most important advantages of CRISPR/Cas9 over other genome editing technologies is its simplicity and efficiency. Since it can be applied directly in embryo, CRISPR/Cas9 reduces the time required to modify target genes compared to gene targeting technologies based on the use of embryonic stem (ES) cells.
Disadvantages of CRISPR technology: CRISPR-Cas9 off-target; The effect of off-target can alter the function of a gene and may result in genomic instability, hindering it prospective and application in clinical procedure.
this the best i got, hope it helps :)
