Answer:
soil; rice
Explanation:
Bacillus cereus is naturally found in the soil. B. cereus is known to contaminate rice, which, if undercooked and ingested, can lead to gastroenteritis. In this example, the reservoir for B. cereus is the soil, and the source of infection is the rice.
A reservoir refers to the breeding ground or natural habitat of micro living organisms such as bacterias, fungi, worms, etc. Thus, a reservoir hosts or harbours pathogens and usually serves as a source of infection to other living organisms.
On the other hand, a source of infection refers to a contaminated material from which a disease can be acquired by another living organism.
Answer: Spinal cord.
Explanation:
The spinal cord of the central nervous system helps to move off quickly as a part of the reflex response. Jill stepped on a tack and suddenly he realizes that he should quickly move his legs out of the tack.
The pain is not stimulated until the signals reaches from the receptor to the brain. The formation of the reflex arc ensures that the amount of potential tissue damaged is less.
It forces the body to move quickly from the place that is causing damage.Example: Moving the leg up involuntarily when stepped on pin.
This occurs because the sensory neurons connects to the motor neurons within the spinal cord.This leads to the contraction of bones and muscles.
Hence, the correct option is spinal cord.
The answer is light.
One of the factors that affect photosynthesis is light. Without light, the photosynthetic rate is reduced or even stopped which consequently affect algal growth. With increasing depth in the ocean, there is less sunlight present. Still, a<span>lgae have accessory photosynthetic plastids other than the chloroplasts</span><span> that can absorb different light in greater ocean depths. This helps them to maximum use sunlight in such conditions. But, in the end, at some particular depth, they would not be able to survive.</span>
Answer:
gene
Explanation:
The basic unit of heredity that occupies a specific location on a chromosome is a gene.
Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.
