The original population of brown spotted deer declined drastically after their forest habitat was flooded. After frantic efforts over three decades by the forest authorities to revive the dwindling population, it did bounce back.

All of the chemical reactions within an organism is known as_____.

Answers

Answer

All of the chemical reactions within an organism is known as metabolism

Explanation:

Metabolism: It is chemical reactions that place inside the living organisms that are important to provide energy and proper functioning of the body.

Purpose of Metabolism:

  • It helps in the conversion of food molecule into a form of energy which helps in cellular processes.
  • It helps in the removal of waste material like a nitrogenous waste.
  • It converts the food to a protein molecule, nucleic acid, carbohydrates and into lipids which provide energy to the body.

Metabolism refers to all chemical processes that take place within an organism. All of the chemical processes that an organism undergoes in order to preserve life are collectively referred to as metabolism. An organism derives energy from food and uses it in this process to go about its everyday tasks.

Anabolism and catabolism are the two primary processes of metabolism . Catabolism is the breakdown of larger molecules into smaller ones, whereas anabolism is the process of building larger molecules from smaller ones.

All organisms depend on metabolism to maintain homeostasis and control the internal environment of the body. Additionally, metabolism aids in the growth and development of organisms as well as their ability to adapt to changes in their environment.

Khalad is measuring the amplitude of a wave. What can be known about this wave?

Answers

The answer is the wavelength.
If Khalad is measuring the amplitude of the wave, therefore, he might also learn the length of the wave. The amplitude of the wave refers to th distance from a rest position to the crest position which distance is half vertically from a trough to a crest. By looking at the amplitude, Khalad doesn't only see the distance but also the length.

1. Which of the following is responsible for transmitting an impulse across a synapse to another cell?

Answers

You didn't really provide any possible answers here. However, it's very easy to say that the responsible actors for impulse transmission across the synapses from one nervous cell to another nervous cell is what we call neurotransmitters. These are special molecules that can have different effects when binding onto the required receptor sites. 

Which theory suggests that the basic unit of life is the creature or organism, which may be divided into cells?cell theory
organismal theory

Answers

The correct answer is organismal theory.

Simply put, this theory states that the original cell expanded into a whole organism, and that the original cell is equivalent to the whole organism and that the protoplasm is just subdivided  and partitioned off by cell walls which are really not complete partitions because the protoplasm of neighboring cells are joined together by plasmodesmata. 

This is opposed to the cell theory that states a cell divides into many cells with the original cell being identical to the daughter  cells.

The correct answer is organismal theory.
