Answer:
There are three types of neurons are present i. e. sensory neuron, motor neurons and inter neurons.
Explanation:
Sensory neurons are the nerve cells which is responsible for sending the information from the sense organs such as tongue, nose, skin, ears, and eyes to the spinal cord and the brain while the motor neurons are responsible for the transportation of instruction from the brain and spinal cord to the muscles. The inter neuron helps in communication between motor or sensory neuron and the nervous system.
Answer:
DNA
Explanation:
Experiments such as the one by Frederick Griffith in 1928 showed that DNA is the hereditary molecule. How showed that virulent bacterial species could transfer DNA to avirulent species and make them virulent too. This means that DNA determines the characteristic of the individual and can be passed down or across generations.
The overall function of the digestive system as digestion and absorption of food stuffs, and the general activities of each digestive system organ is; Ingest, digest, absorb, defecate.
Ingestion involves placing food into the mouth, propulsion involves propelling food from one organ to the next using peristalsis. Mechanical digestion involves the physical fragmenting food into smaller particles. Chemical digestion refers to breaking down food molecules to building blocks by enzymes. Absorption is the transport of digested end products to blood or lymph; and finally Defecation which involves the elimination of indigestable material from GI tract by anus.
Answer:
B) They are producing more crops
Explanation:
GMOs are designed to increase crop productivity because of supply and demand, which in turn makes the supplier more money, and more happy people/companies that buy the crop. Additionally, the other answer choices would be considered bad traits.
Living systems are open self-organizing life forms that interact with their environment. These systems are maintained by flows of information, energy and matter. Some scientists have proposed in the last few decades that a general living systems theory is required to explain the nature of life.
