how does a scientist get the corrected version of a gene into the cells of a gene therapy patient?
Answer:
In order to insert new genes directly into cells, scientists use a vehicle called a “vector” which is genetically engineered to deliver the gene. Viruses, for example, have a natural ability to deliver genetic material into cells, and therefore, can be used as vectors.

"Medical practices without scientific basis is the greatest form of quackery."
DO YOU AGREE ON THIS STATEMENT? YES OR NO? DEFEND YOUR ANSWER...
answer this please :)
I need it as soon as possible.....
thank you:)
Answer:
Yes, Medical practices, almost always dealing with a person's well-being and life, must prioritize the safety of the person involved. Therefore, to remove or even lessen the risk to a person's life, all procedures done to them must always have a scientific backing, not one backed with beliefs and hoaxes.
What exactly is Quackery? It is the characteristic practice of quacks or charlatans, who pretend to knowledge and skill that they do not possess, particularly in medicine. The quack makes exaggerated claims about his or her ability to heal disease, generally for financial gain.
The conditions usually treated by quacks are those for which specific methods of treatment have not yet been developed; those particularly feared, such as cancer, sexually transmitted diseases, and, in the past, tuberculosis; those with frequent remissions and recurrences, such as arthritis, neuritis, and migraine; and mental disorders. People yield to quackery in times of great stress, pain, or sorrow. In the absence of exact knowledge, and sometimes even in its presence in the face of insurmountable difficulties, the credulous person craves a miracle and is ready to be overwhelmed by the personality and the claims of the charlatan.

research has found that the nucleus accumbens and the amygdala, both of which are part of the ________, are brain areas that are particularly important in sexual motivation.
Answer:
What is the basal forebrain.
Explanation:
The Nucleus accumbens and the Amygdala are the part of the Limbic System.
What is the Limbic System?
The limbic system is the part of the brain involved in behavioral and emotional responses, especially when it comes to behaviors that is required for survival ,feeding, reproduction and caring for our young, and fight or flight responses.
The limbic system is located within the cerebrum of the brain, immediately below the temporal lobes, and are buried under the cerebral cortex (the cortex is the outermost part of the brain).
Limbic system comprises of:
- Limbic cortex
- Hippocampal formation
- Amygdala
- Septal area
- Hypothalamus
What is Nucleus Accumbens?The nucleus accumbens is a region in the basal forebrain rostral to the preoptic area of the hypothalamus.
The nucleus accumbens has a significant role in the cognitive processing of motivation, aversion, reward , and reinforcement learning hence, it has a significant role in addiction.
In addition, part of the nucleus accumbens core is centrally involved in the induction of slow-wave sleep. The nucleus accumbens plays a lesser role in processing fear (a form of aversion), impulsivity, and the placebo effect. It is involved in the encoding of new motor programs as well.
What is Amygdala?The amygdala is an almond-shaped structure, located right next to the hippocampus.
The main function of the amygdala is in emotional responses, including feelings of happiness, fear, anger, and anxiety.
This area is also key for the formation of new memories. The amygdala interacts with the hippocampus by attaching emotional content to memories.
It has a role in how memorable memories can be – memories that have strong emotional components tend to stick, rather than those with little emotional content. ‘Fear learning’ is also an element of the amygdala.
Damage to the amygdala can result in more aggression, irritability, loss of control of emotions, and deficits in recognizing emotions, especially recognizing fear.
There are also links of amygdala differences in those with Autism, depression, posttraumatic stress disorder, and bipolar disorder.
