A mutagenic agent is any chemical, physical or biological compost that can induce a mutation in the cell's DNA, making this mutation pass to the next generation.
Mutagenic agents are widely used in the fields of biotechnology, genetic engineering, medicine and agroindustry. This is because these agents have helped in the advancement and development of new technological tools.
In genetic research some bacteria and viruses are used by agribusiness companies to obtain transgenic beings. These mutagenic (biological) agents act as vectors of laboratory-created genes that will insert these genes into an organism to be modified. It could be, for example, a gene that will improve maize resistance against a pest. Thanks to mutagenic agents, this genetic information can be passed on to the organism, in this case, the plant.
Answer:
25. red
24. A. Temperature and Luminoscity
Explanation:
Answer:
<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>
<u></u>
Explanation:
Neurons, specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.
Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:
- photoreceptors
- mechanoreceptors
- chemoreceptors
- thermoreceptors
Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.
