The neurons conduct impulses over relatively long distance in the body. This is facilitated by their long cytoplasmic extensions
The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.
<h3>What are restriction enzymes?</h3>
They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.
The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

Answer:
The correct answer is: positive feedback.
Explanation:
Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance <u>inhibits</u> its producer that is called <u>negative feedback</u>. On the other hand, when a substance <u>stimulates</u> its producer to keep secreting said substance, this is called <u>positive feedback</u>.
Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).
Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.
Answer:
The correct answer is : Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.
Explanation:
Louis Pasteur's experiment with cooking shows that the microbes or germs that cause spoilage of food and disease after eating to an individual, could be killed by the heating process.
His experiment shows that microbes cause food and liquid spoilage which can be prevent by the process of the pasteurization or heating that kill such germs.
Thus, the correct answer is - Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.
The mean of 2,5,1,1,9,1,2 = 3
2+ 5+1+1+9+1+2 =21
21/7 = 3
