Answer:
This question lacks options, the options are:
A) symbiosis
B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.
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.
Answer:
warm temperature
Explanation:
<em>I cannot see the choices in your image. I can only see choice A, which is "soil."</em>
"Abiotic factors" are part of the ecosystem that don't have life. However, they have an<em> impact </em>on the<u> life of the</u><u> biotic factors</u><u> </u><em><u>(living organisms)</u></em><u> in the environment.</u> Examples of abiotic factors are:<em> sunlight, temperature, climate, soil, humidity, wind, etc. </em>
"Boreal forests" are abundant on the Earth's Northern Hemisphere. The climate here is generally cold, which doesn't allow some trees to survive. It is totally opposite to the warm temperature and high humidity that you can feel in the<em> "tropical forests." </em>Such factors allow many plants and animals to survive.
Clearly, the boreal forests lack the "warm temperature" that the tropical forests have.
