What are some good and bad results on irradiation being used on seeds

malfutka [58]3 years ago

Explanation:

The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize. Maize dry seeds are exposed to a gamma source at doses ranging from 0.1 to 1 kGy. Our results show that the germination potential, expressed through the final germination percentage and the germination index, as well as the physiological parameters of maize seedlings (root and shoot lengths) decreased by increasing the irradiation dose. Moreover, plants derived from seeds exposed at higher doses did not survive more than 10 days. Biochemical differences based on photosynthetic pigment (chlorophyll a, chlorophyll b, carotenoids) content revealed an inversely proportional relationship to doses of exposure. Furthermore, the concentration of chlorophyll a was higher than chlorophyll b in both irradiated and non-irradiated seedlings. Electron spin resonance spectroscopy used to evaluate the amount of free radicals induced by gamma ray treatment demonstrates that the relative concentration of radiation-induced free radicals depends linearly on the absorbed

Answer:

Medical uses: The field of genetic engineering is making progress rapidly and it has helped doctor's to fight many challenging diseases. One of the medical use of genetic engineering is the production of insulin by genetic engineering and also the production of vaccines through this technique.

Agricultural uses: The field of biotechnology can change the life of farmers once it is fully known that the genetically engineered crops cannot harm the humans. One of the uses of genetic engineering in agriculture is the production of crops containing increased nutrition. For example,Golden rice which carries vitamin A in it.

Environmental uses: Genetic engineering is used to clean the Earth by producing genetically engineered microorganisms which can not only break down waste but also can degrade plastics.

The treelike fibers that receive information and send it toward the neuron's cell body are called ____
Firdavs [7]

Answer:

The treelike fibers that receive information and send it toward the neuron's cell body are called Dendrite

Explanation:

Dendrite:-  They are tree like projections generally the extension of nerve cell which helps in the transmission of nerve impulses or electrochemical stimulation from one neuron to another. It is also known as dendrons. For neurons to become active they need some action potential, these action potentials are received in the form of nerve impulses or electrochemical stimulation by dendrite and is been stored  in the cell body, or soma, of the neuron. Dendrites are covered by synapses (Structure that permit neural transmission).
