Answer:
Genetic engineers can transfer a specific piece of DNA or genes from one organism to another organism. This is usually done by adapting recombinant DNA methods. In this approach, a gene of interest is cut with restriction enzymes and then inserted and ligated to the host genetic material. This host could be a bacteria or eukaryote.
Example: Biotechnologists can produce insulin by inserting human gene in <em>E. coli</em>. The bacteria replicate its genome fast and produce protein (insulin) which can be extracted and applied to the person who is diabetic. Similar methods have been used for other purposes.
Answer:
(the freeze-thaw cycle) is called frost weathering or cryofracturing, the water inside of rocks freezes so that expands and cracks the rocks from the inside and eventually breaks them apart.

Answer:
Hearing
Listening
Explanation:
Hearing refers to the vibration of sound waves on the ear drums and the sending of messages to the central auditory system of the brain. The mechanism involve the use of Pinna also known as auricle to gather sound waves which is transferred into the tympanic membrane along the air canal.In the tympanic, sound waves vibrate following the waveform of the sound.
In the middle ear, the ossicles of the middle ear(malleus, incus, stape) assist in the transmission of the vibrations from the tympanic membrane into the inner ear (the cochlea).
The cochlea serve as a mechanical-neural transduction pathway, it helps to transmit sound information via the auditory nerve to the cochlear nucleus in the brainstem.
Listening refers to paying close attention to and making sense of those sounds perceived from the surrounding environment . It is the ability to get the right information without any misinterpretation in the communication process. It is the key to any effective communication.
Answer: yes
T
lieved to spread person-to-person between people who are in close contactet) with one another. Some people without symptoms may be able to spread the virus.
Explanation
Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by <em>nuclear pore complex.</em> It allows the pore to <u>regulate the movement of molecules between the nucleus and the cytoplasm.</u> It allows small particles to pass through such as ribosomal proteins. It prevents most large particles<em> (except for histone)</em> from passing through; thus, <u>it is selective in nature</u>. This function of the pores clearly shows that <em>it allows communication to occur between the nucleus interior and the cytoplasm.</em>
