Microscope is one of the invention for scientist to practice direct observation. It allows scientists to observe the world in micro scale.
Answer:
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
Neurons in the <u>spinal cord</u>, control motor reflexes, which allows rhythmic and automatic movements to be carried out.
The spinal cord represents the lowest level in the hierarchical system that regulates reflex motor activity, voluntary movements, and body posture.
Therefore, their neurons have been organized into circuits that participate in simple automatic gait movements and simple defensive movements (withdrawal of the muscle in the event of any aggression) through reflex responses.
The motor neurons of these circuits are located in the anterior horns where they are arranged forming the so-called "poles" of motor neurons, equivalent to true motor neuron nuclei.
- Alpha motor neurons their axons are myelinated and they group together in the medulla and form columns that are known as motor nuclei.
- Gamma (γ) motor neurons innervate muscle fibers of the muscle spindle.
- Interneurons can be excitatory or inhibitory.
Therefore, we can conclude that neurons in the spinal cord, control motor reflexes, they present functional interactions between them and this allows rhythmic and automatic movements to be carried out with ease through reflex responses.

Hydroelectric energy is created from flowing water
Answer:
Say the dominant gene is G, for free earlobes. Say the recessive gene is g.
We only need one G for free earloves to show. The possible genotypes are,
Gg and GG.
