Plz I need help with this!! Explain how entropy relates to the amount of energy that is available in the different trophic levels of a food chain

Answers

Answer:

There ya go!!

Explanation:

Entropy is defined as the measure of heat that is available in any kind of system. When moving towards the next levels in the food chain, the distribution of heat will be less at each stage and at the lower levels of food chain the heat energy that is produced will be high and the value of entropy will be less.

Answer:

Entropy is the tendency of a system towards a larger number of random arrangements. Overall, entropy must increase during processes, so a system will tend towards greater disorder. The energy available for organisms decreases from one trophic level to another, because some of the energy is dissipated as heat from each level to the next because of that tendency toward disorder.

The cranial cavity and the vertebral canal contain the __________.

Answers

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.

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.

An enzyme known as amylase is found in the saliva of humans. This enzyme helps to begin the process of digesting starch molecules in the foods we eat. Which of these BEST describes how enzymes like amylase help in the process of digestion? (AKS 1a1) Question 2 options: Amylase contains the DNA molecules necessary to assemble the proteins needed for digestion. Amylase is a catalyst that speeds up the chemical process of breaking down food molecules. Amylase breaks down the food molecules directly by forming powerful acids. Amylase acts as a buffer to keep the pH of foods at a consistent level.
