Option B- They play a minor role in biological and geo-chemical cycles is the right answer.
Marine microbes are tiny, single-celled organisms that live in the ocean. They play a major role in biological and geo-chemical cycles.
Pathogens are any microorganisms that cause disease. These include viruses, bacteria, and parasites. They can spread via contaminated food and water; from one sick person to a healthy person; through contact with blood-containing pathogens; endogenous infection during an immunocompromised state.
Water- and food-borne pathogens are spread via uncooked meat, improperly washed fruits and vegetables, and unsanitary practices of food handlers.
Blood-borne pathogens are spread via vectors like mosquitos, and accidental injections of dirty syringes that were used on patients with hepatitis B or HIV.
A person can be immunocompromised when the patient is undergoing chemotherapy, chronic or prolonged use of corticosteroids, or if he or she is simply born with a weak immune system. In this state, the person can easily be infected with normally harmless bacteria that live inside of us.
At high latitudes, ocean water receives less sunlight. Thus, the surface waters in the Arctic and Antarctica are not warmed much; in fact they are very cold
so false
Answer:
A. Relay neurons
Explanation:
Neurons or nerve cells are one of the cell types contained in the nervous system. Neurons transmit or carry nerve signals. There are three major types of neurons namely; motor neurons, sensory neurons, and interneurons.
Specifically, interneurons or relay neurons are types of neurons that connects the sensory and motor neurons i.e carrying signals from the sensory neurons to the motor neurons?
