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

Answer:After witnessing plant and animal cells under a microscope, scientists Schwann and Schleiden made the conclusion that all living organisms are composed of cells. This discovery was significant because it laid the foundation for the cell theory, which states that cells are the basic units of life.

Schwann, a zoologist, observed animal tissues and noted that they were composed of individual cells. Schleiden, a botanist, made a similar observation while studying plant tissues. Both scientists realized that cells were the fundamental building blocks of living organisms.

This conclusion was supported by several examples. For instance, when examining plant cells, Schwann and Schleiden noticed that they had a cell wall and a distinct nucleus. Similarly, animal cells lacked a cell wall but had a nucleus and other cellular components. These observations led them to propose that all living organisms are made up of cells, regardless of whether they are plants or animals.

The discovery of the cell as the basic unit of life revolutionized biology and had a profound impact on our understanding of living organisms. It provided a unifying principle for the study of life and opened the door to further research and discoveries in the field of cell biology.

Explanation: im not gonna take credit for this answer it was the AI tutor Ginny.

Answer:

A physical environment with different species that interact with one another and with nonliving things is called an ecosystem.

Ecosystem is the functional unit of nature. An ecosystem can be different in size according to the communities living in that ecosystem. Abiotic and biotic components together make an ecosystem.

Chemical and physical factors come under abiotic components. Physical components like water, air, light, temperature have more effects on the ecosystem than chemical factor.

Organisms are the biotic component of an ecosystem. They can be autotrophs or heterotrophs. Many organisms make a population, many populations combine to form community and many communities combine to form an ecosystem.

Organism↔Population↔Community↔Ecosystem

The answer is homeostasis.

Of the following given choices;

A. glacial erratics B. U-shaped valleys C. unusually shaped rocks D. mudslides.

The answer is; C.

The wind carries soil particles is it blows. These soil particle hit on rocks in their path and over time gradually erode the rocks. An example of this type of erosion is the aeolian process. Usually the bottom o the rock is eroded more than the top. This is because the bottom is hit by larger soil particles that are heavier to carry by the wind. An example of rock formed in this process is attached in the picture below.

HOPE THIS HELPS! :)

Zoo is place where animals are maintained for public display.

Sanctuaries are protected regions where wild animals live in natural habitats.

zoo:. Animals are brought from different parts of the country. sanctuary:It contains animals native to that area.

zoo: It is an artificial habitat. sanctuary: It is a natural habitat.
