Explanation:
Trust me
The answer would be A
Because
The sense of smell is part of our chemical sensing system, or the chemosenses. Sensory cells in our nose, mouth, and throat have a role in helping us interpret smells, as well as taste flavors. Microscopic molecules released by the substances around us (foods, flowers, etc.) stimulate these sensory cells. Once the cells detect the molecules they send messages to our brains, where we identify the smell. Olfactory, or smell nerve cells, are stimulated by the odors around us--the fragrance of a gardenia or the smell of bread baking. These nerve cells are found in a small patch of tissue high inside the nose, and they connect directly to the brain. Our sense of smell is also influenced by something called the common chemical sense. This sense involves nerve endings in our eyes, nose, mouth, and throat, especially those on moist surfaces. Beyond smell and taste, these nerve endings help us sense the feelings stimulated by different substances, such as the eye-watering potency of an onion or the refreshing cool of peppermint.
Answer: It is important that we use our natural resources so that we use any bad things for our earth
Explanation:
The right matches are:
• Involves the transfer of genetic material from one bacteria to another ==> Genetic recombination (all 3).
• Involves scraps of genetic material ==> Transformation.
• Uses a virus to transmit genetic material ==> Transduction.
• Uses a pilus to transmit genetic information ==> Conjugation.
• Introduces new genetic material to a bacterium ==> Genetic recombination (all 3).
In molecular biology the term genetic recombination is often used as a synonym for DNA recombination, that is, the processes by which one DNA (or RNA) molecule is cut off, then joined to another.
There are three possible mechanisms in the bacterium: bacterial conjugation, bacterial transformation and transduction.
