Answer:

active transport is when molecules move across a cell membrane from a lower concentration to a higher concentration

Explanation:

active transport needs cellular energy to get this movement

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>

Research on obesity and weight control indicates that
shepuryov [24]
The answer is letter d, it is because when a person becomes obese, he or she is likely to intake small amounts of food if he or she wants to maintain his or her weight and if the person does not want to gain weight anymore and than it is more different when gaining weight or when the person was in the point to become obese because he or she has ingested more food to gain weight.

Describe how a business such as a supermarket or a department store uses classification to make it easier for its customers to f
anastassius [24]
In a supermarket it is likely that the store will be divided into many categories to ensure the customer is able to find what they are looking for promptly. for example, at Walmart, you may find a clothing section, a toy section, a produce section, toiletries section, makeup section and bakery section among many others. this style of organization allows for customers to know exactly where they must go to find what they are looking for - if they would like to purchase an apple they would go to produce etc.

solniwko [45]

Answer:

make me brainliest pls hope it helps :)

Explanation:

Electricity 24hrs.

Initial high cost

High loss when natural disasters occur

24 hrs - Water supply (rotation in the system)

No special selling market

Virus or Bacteria disturb to all plants when enter-

High computerization

Different fertilizers (Mineral fertilizers only

So many problems or negative point in Vertical farming but farmers takes benefit- its positive point)
