Answer:
The answer is- A). Because it takes tremendous effort to break free from the laws of gravity to exit the Earth's atmosphere.
Explanation:
I really don't have an explanation. Except that I love science and I actually pay attention in my classes.
Hi, Sulikjon!
The main purpose it to lower the freezing point of water, and we use salt for this.
I hope this helps;)
Answer:
Sympathetic division
Explanation:
Adrenal medulla is located at the center of adrenal gland, surrounded by adrenal cortex. It consists of cells that secrete adrenaline and noradrenaline and also a small amount of dopamine when stimulated by sympathetic preganglionic neurons. Preganglionic autonomic fibers lead to them directly from central nervous system therefore adrenal medulla affects heart rate, available energy, and metabolism.
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 :)
