25. A nerve fiber that conducts impulses toward muscles and glands is called a __________ fiber. A nerve that conducts impulses toward the brain and spinal cord is called a __________ fiber.
Answer:
A nerve fiber that conducts impulses toward muscles and glands is called a _____motor_____ fiber. A nerve that conducts impulses toward the brain and spinal cord is called a ______afferent____ fiber.
A nerve fiber that conducts impulses toward muscles and glands is called a motor neuron fiber. A nerve that conducts impulses toward the brain and spinal cord is called a sensory nerve fiber. Both are important for the proper functioning of the body.
What are sensory and motor nerve fibers?The sensory nerve fibers send the stimulus in the form of an impulse from the sensory organs to the spinal cord, where the sensory organs can be skin, eyes, etc. An example is when a person sees a dog coming towards them, and the sensory nerve fiber that is associated with the eye sends the signal from the eye to the spinal cord. The spinal cord takes proper action by sending the motor nerve fibers to the effector organ, which is the leg muscle. In this case, the individual will run.
Hence, A nerve fiber that conducts impulses toward muscles and glands is called a motor neuron fiber. A nerve that conducts impulses toward the brain and spinal cord is called a sensory nerve fiber.

Using your model, which of these would lead to an increase in carbon dioxide in the atmosphere? Select the TWO (2) that apply
Answer:
Carbon Dioxide is a gas it is always part of the atmosphere. However Carbon Dioxide gas can be removed and returned to the atmosphere.
Explanation:
Plants use Carbon Dioxide as one of the two main reactants in the process of photosynthesis. Photosynthesis removes Carbon Dioxide from the atmosphere turning the Carbon into Carbohydrates, such as cellulose found in wood.
Cellular Respiration, burning coal, wood, gasoline, turn the Carbon-based molecules back into Carbon Dioxide and water. These Oxidation reactions return the Carbon Dioxide to the atmosphere

Does photosynthesis occur in all plant cells?
Answer:
No- not all, but most.
Explanation:
The newly discovered plant — named Gastrodia kuroshimensis — occurs in the dark understory of forests where little light penetrates. So instead of using sunlight or photosynthesis to generate nutrients, the plant parasitizes the fungi in the forest soil for its daily dose of nutrition.
Answer:
No Not all, but most
Explanation:
In 2001, scientists found a fossilized skeleton from about 110 million years ago. The fossil resembled a modern crocodile in virtually every way, except for one: The fossil was 40 feet long, which is almost twice as long as the largest modern crocodile ever found. From this discovery, scientists concluded that
We can confirm that scientists used this discovery to conclude that crocodiles evolved to be smaller over time.
Why would small size help Crocodiles?Over time, many animals on the Earth evolved to smaller sizes. This made large predators unlikely to survive as they would need to hunt much more often than that of smaller predators in order to sustain themselves. This along with an increase in mobility explains some of the reasons why it was beneficial for crocodiles to evolve to be smaller over time.
Therefore, we can confirm that scientists used this discovery to conclude that crocodiles evolved to be smaller over time.
