The correct answer is C. Sphagnum moss
Explanation:
In biology, a renewable source of energy refers to a type of source that replenishes and therefore can be widely used to obtain energy such as wind energy or solar energy that are almost always available. On the other hand, a seedless plant is a type of plant that does not have seed and because of this, they reproduce through sperms.
All fo the plants listed (club moss, horsetail, fern and sphagnum moss) belong to the category of seedless plants; however, from this, the only one that has been widely used a source of energy is sphagnum moss because dried sphagnum moss or peat moss is used as carbon or coals source and therefore is useful for heating building and because it is a plant that grows extensively it is also a renewable source.
Answer:
Heterotrophic species that eat organisms from different trophic levels
Explanation:
Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.
The question is incorrect. The correct question is as follows:
Nerve cells, the basic elements of the nervous system, have a cell body that contains a nucleus. Physically held in place by glial cells. They have the ability to communicate with other cells and transmit information across relatively long distances
Answer:
Neurons.
Explanation:
The nervous system is one of the most important system of the body that coordinates and maintains the other system of the body. The nervous is divided into two main parts - peripheral nervous system and central nervous system.
Neuron is the structural and the functional unit of the nervous system. The nervous system contains the million of neuron that conducts the information from one part of the body to another. They are held together by the glial cells also know as glue and travels communication through the long distances.
Thus, the answer is neurons.
By nerve cells the heart has neurons and they work based on electrical potential.
