Help pls- <br><br> compare and contrast evaporation and boiling
DENIUS [597]
So the simple answer would be evaporation is slow and can only occur through the surface of a liquid and it cools it down, while boiling is fast and produces bubbles ( evaporation does not ) and it occurs throughout the liquid and doesn’t cool it down. A similarity between the two would be water vapor is given off
Both the processes of evaporation and boiling result in a change from liquid to vapor.

hope this is what u we’re looking for and this helps !! :)

Describe the origin and fiber composition of (1) ventral and dorsal roots, (2) the spinal nerve proper, and (3) ventral and dors
Zigmanuir [339]

Answer:

A dorsal root (sensory or afferent) and a ventral root (motor or efferent) originate from the medulla. They unite near the intervertebral foramen, forming the spinal nerve. The nerves emerge from the intervertebral foramen, dividing into ventral and dorsal ramus.

Explanation:

The nerve is a set of nerve fibers perceptible to the naked eye and wrapped in connective tissue. They are made up of roots, trunks and nerve branches (some of them come together and form plexuses).The spinal nerve originate from the spinal cord in the form of 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal. They emerge from the spinal cord through two roots: dorsal roots, made up of sensory fibers that come from the sensory neurons of the spinal ganglion and that penetrate the spinal cord through the posterolateral  and ventral root, made up of motor fibers, coming from the motor neurons of the anterior horn and visceral of the lateral horn of the gray matter of the spinal cord. This root exits the spinal cord through the anterolateral groove, then joins the posterior root to form the spinal nerve, which exits the vertebral canal through the corresponding intervertebral foramen.Each spinal nerve, after leaving the vertebral canal, emits two primary ramus: the dorsal ramus, contains somatic and visceral fibers that go to the skin and muscles of the back and the ventral ramus, which supplies the ventrolateral surface of the skin, body wall and extremities.

___________cycle nutrients from dead organisms back to the soil where it becomes available for plants
mezya [45]

<u>Answer:- </u> Decomposition

<u>Explanation:- </u>

Decomposition is a natural process that occurs in the environment to break down organic substances into simpler substances.

  • All the living organisms that die, are decomposed and their bodies are broken down into simpler substances such that the nutrients are released into the soil.
  • The plants are then able to absorb these nutrients from the soil and thus, the nutrient cycling goes on as the organisms feeds on it.
  • Not only the dead animals but also the fallen leaves and other parts of the plant gets decomposed as they die.
  • The process of decomposition is carried out by living organisms present in the soil such as bacteria. Such organisms are called as decomposers.
