The cranial cavity and the vertebral canal contain the __________.

Answers

Answer 1
Answer:

The cranial cavity and the vertebral canal contain the spinal cord

Vertebrae is the synonym of spine. Inside the spine, there will be spinal cord protected by the nearby bone. Spinal cord will divided into many smaller cords after leaving the spine and spread through the body to carry signal from/to the brain. Without the spinal cord, the brain will not be able to reach and control the body.
Answer 2
Answer:

Final answer:

The cranial cavity and vertebral canal contain the brain and spinal cord, respectively, which make up the central nervous system and are protected by cerebrospinal fluid.

Explanation:

The cranial cavity and the vertebral canal contain the central nervous system, which includes the brain and the spinal cord respectively. Vertebrate animals have two major body cavities: the dorsal cavity and the ventral cavity. The dorsal cavity contains the cranial cavity, which fills most of the upper part of the skull and houses the brain, and the spinal cavity, also known as the vertebral canal, which is a long, narrow cavity inside the vertebral column that contains the spinal cord. These two cavities are continuous with one another, forming a protective environment for the central nervous system complemented by cerebrospinal fluid, which acts as a cushion and circulates through both cavities and their contained structures.

Pumps move substances ____________ a concentration gradient, a process that requires energy. Channels instead provide the means to move a substance ____________ a concentration gradient. Neurons contain the following major types of channels: • Channels that are always open, allowing continuous diffusion of a specific ion from a region of ____________ concentration to a region of ____________ concentration are leak channels. • Channels that are normally closed that open in response to the binding of a ____________ are chemically gated channels. When open, they allow a specific ion to ____________ across the plasma membrane. • Channels that are normally closed, but open in response to changes in ____________ across the plasma membrane are voltage-gated channels. When open, they allow a specific ion to diffuse across the membrane.

What is concentration gradient

The difference between two areas' concentrations of a material is referred to as a concentration gradient. It is the difference in concentration over a certain distance, usually between two areas of different concentrations. It could be a molecule, an ion, or another type of chemical compound.

Traveling "against" the concentration gradient entails traveling from a region of higher concentration to a region of lower concentration, while moving "with" the concentration gradient entails doing the opposite.

Plants have a cell wall made of cellulose. What is the function of the cell wall in plants? A) The cell wall controls division of the cell. B) The cell wall provides structure to the cell. C) The cell wall controls the functions of the cell. D) The cell wall manufactures proteins for the cell.

Answers

The main job of the cell wall made out of cellulose would be to provide structure to the cell - B. 

Having structure through the cellulose present in cell walls is essential for plants because their structure often also dictates their function. 

A the cell wall controls division of the cell
