The observed results of an experiment that occur from changes in the independent variable are known as dependent variable.<span>
Variables are observable and measurable objects used in a study.
Independent variables are those variables manipulated to produce a desired or predicted outcome whereas the dependent variable is the variable that receives the treatment and produces the product. </span>

D.  dependent variables

The observed results of an experiment that occur from changes in the independent variable are known as dependent variables. For example, if a student wants to determine how the amount of water given to a plant effects how much the plant grows, the growth of the plant is the observed result that occurs because of changes to the amount of water the plant receives.

ANEK [815]

Answer:

Answer is A. allow them to control all the variables involved.

Explanation:

Modelling in ecology means the use of constructed mathematical models for understanding of ecological processes and to predict or know how real it is for ecosystem to change.

Ecological modelling is useful in defining problems more precisely and clarity of concepts.

Cellular Respiration, please help this is due tomorrow and I don't get it at all.
saw5 [17]

Answer:

What does cellular respiration due?

<h2>Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.</h2>

Explanation:

<h2>What are the 7 steps of cellular respiration in order?</h2>

<h2>Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made.</h2>

...

<h2>Glycolysis. ... </h2><h2>Pyruvate oxidation. ... </h2><h2>Citric acid cycle. ... </h2><h2>Oxidative phosphorylation</h2>

<h2>Answer</h2>

<h2> Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.</h2>

Place the steps involved in burning coal to create electricity in the correct order.
butalik [34]

Answer and Explanation:

  1. Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area.
  2. Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam.
  3. Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines.
  4. Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.
