“The U.S. government considers biodiesel to be carbon-neutral because the plants that are the sources of the feedstocks for making biodiesel, such as soybeans and palm oil trees, absorb carbon dioxide (CO2) as they grow. The absorption of CO2 by these plants offsets the CO2 that forms while making and burning biodiesel.”
Interneuron, skeletal muscle, somatic receptor, afferent nerve fiber, and efferent nerve fiber.
The action potential from skin receptors is sent by nerves in this type of reflex system.
Sensory neurons advance the motion to the Central Nervous System (CNS).
The efferent neuron or motor neuron causes changes at the effector, which are the skeletal muscles, for adequate integration and responsiveness.
Reflex action refers to the full series of actions. The reflex arc is the name of the route.
Somatic receptor followed by afferent nerve fiber, interneurons, efferent nerve fiber, and skeletal muscle constitutes the proper order.

I believe the answer is plants make flowers to attract insects because, plants do nit store carbohydrates, meat does, and we cant use plants to create fossil fuel. The only plant fibers we use for clothing is cotton so that is very limited in the wide aspect of things.
Answer:
Dust bowl resulted from extreme drying and loosening of the soil that resulted in soil erosion by wind. Thus, it can be related that poor agricultural practices like over plowing , over grazing and leaving the land barren are human activities that must have contributed to the dust bowl.
Explanation:
- Dust bowl is referred to a period in early twentieth century when the the American and Canadian prairies faced severe dust storms.
- These dust storms resulted from severe drought and failure of practices to prevent soil erosion.
- Several people and livestock died as a result of choking.
- Over plowing, removal of top soil and small grasses exposed the soil to eroding winds and caused the dust storms.
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
