Answer:
B. The population size will decrease
Explanation:
Abiotic factors may include temperature, sunlight and water. If conditions are too cold for the organisms living there, they may perish. If the amount of sunlight decreases, plants will not be able to produce enough glucose through photosynthesis. If the amount of water decreases plants may bot have enough water to photosynthesise and animals will have to compete for water.
An ecological relationship is the relationship between an organism in its community.
Answer:
A sensory neuron.
Explanation:
The nervous system can be divided in two systems: the central nervous system and the peripheral nervous system. The central nervous system (CNS) is composed by the brain and the spinal cord. The peripheral nervous system (PNS) consists of the nerves and ganglia. Neurons are specialized cells that form the basic functional unit of the nervous system. There are three types of neurons: sensory, motor and interneurons. The sensory neurons are in charge of bringing signals into the CNS, and the motor neurons are in charge of carrying signals out of the CNS. The interneurons act as intermediaries, passing information between two neurons.
As the name implies, sensory neurons are activated by the senses, for example: sound, visible light, physical contact (heat and cold), chemical signals (smell and taste). The loss of sensation in one hand would be the result of a damaged sensory neuron.
