C. interneuron -> sensory neuron -> motor neuron
D. None of these

Answers

Answer:sensory nuerone to internuerone to motor neurones

Explanation:

The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.

These receptors send signals as action potential to the spinal cord to the brain.(CNS).

Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.

The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.

The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction

Grass obtains 10% of the energy of the Sun. When a mouse eats the grass, it gets only _____ of the Sun's energy while _____ is lost as heat.

Answers

Grass only obtains 10% of the energy of the Sun. When a mouse eats the grass, it only gets 1% of the energy of the sun, while the remaining 9% is lost as heat. Remember, an average of 10% of the sun’s energy is transferred, in each link of the food chain. So, the answer would be 1% of the sun energy.

Pedigrees and karyotypes provide the means for individuals to identify their risks of genetic disorders. What can be evident on a karyotype but not seen on a pedigree? A. family carriers of a genetic disorder B. family history of a genetic disorder C. risk of a genetic disorder in offspring D. a visual image of a chromosomal defect.

Answers

I think the correct answer from the choices listed above is option D. The thing that can be evident on a karyotype but not seed on a pedigree would be that the presence of a visual image of a chromosomal defect. Hope this answers the question. Have a nice day.

Answer:

The correct answer would be D. a visual image of a chromosomal defect.

Karyotype is defined as a visual display of the number and appearance of all the chromosome present in the cell.

It is used to detect any chromosomal abnormality such as a change in chromosome number, change in chromosome set, malformed chromosome et cetera.

In contrast, a pedigree chart is a diagrammatic representation of phenotype or appearance of a particular gene in a number of generations.

it shows the family history of the genetic disorder, risk of that disorder in an offspring, et cetera.

with your group describe a short statemetn that describes the connection between nutrient levels, dissolved oxygen, biological oxygen demand, plants, fish, and decomposers

Answers

When there is an excess amount of nutrients for water plants, Eutrophication occurs. It is a form of Water Pollution. During the Eutrophication, nutrients are released from the sewage to water. With the excess amount of nutrients, algaes and other aquatic plants growth increase. When they die, decomposers use the oxygen in the water for the process. The animals and fishes will die due to lack of oxygen levels.
