Hope it helps
ATP is a crucial energy molecule in cells, providing energy for various cellular processes.
ATP, or adenosine triphosphate, is often referred to as the "energy currency" of the cell. It plays a vital role in cellular metabolism by providing energy for various processes. ATP is composed of adenosine and three phosphate groups. The energy stored in ATP is released when the terminal phosphate group is hydrolyzed, forming ADP (adenosine diphosphate) and inorganic phosphate (Pi).
The role of ATP in a cell is multifaceted. Firstly, ATP powers cellular work by providing the energy needed for chemical reactions, such as biosynthesis, active transport, and muscle contraction. It acts as an immediate source of energy that can be rapidly used by the cell.
Secondly, ATP participates in signal transduction and cellular communication. It can be hydrolyzed to ADP and Pi, releasing energy that can activate signaling molecules and enzymes involved in cell signaling pathways.
Furthermore, ATP is involved in maintaining cell homeostasis. It provides energy for processes like ion pumps that maintain the electrochemical gradients across the cell membrane, allowing cells to regulate their internal environment.
Overall, ATP is crucial for the functioning of cells as it serves as an energy carrier, facilitating energy transfer and powering various cellular processes essential for growth, metabolism, and cell survival.

gravitational force related?
A. Mass and gravitational force are the same.
B. An increase in mass is a decrease in force.
C. An increase in mass is an increase in force.
O D. Mass and gravitational force are not related.
Explanation:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water.
The combustion is an example of an exothermic reaction.
An exothermic reaction is a reaction that releases energy, this energy is usually in the form of heat. An endothermic reaction is a reaction that absorbs energy to take place.
Analyzing the given reactions we have that:
Evaporation: need to absorb energy to increase the kinetic energy of the moleculesMelting ice: need to absorb energy to increase the kinetic energy of the moleculesCombustion: releases energy after forming bonds between moleculesDecomposition: need to absorb energy to break moleculeSo, the combustion is an example of an exothermic reaction.

What is the chemical equation for cellular respiration?
What role does photosynthesis play in our environment?
Answer:
Cellular Respiration:
C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy)
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle wouldn't occur/exist, oxygen-requiring life would not survive and plants would die. Without photosynthesis there would be little to no oxygen on the planet and Earth would be impossible to live on.

Pressure Cooking
Explanation:
Pressure cooking is a very old cooking method that’s experienced a recent resurgence thanks to a new generation of cookers that promise a speedy, set-it-and-forget-it path to dinner. These devices, whether electrical or stovetop, are all much safer than those of decades ago (which tended to explode), with mechanisms to prevent them from accumulating too much pressure. If you read the owner’s manual carefully, however, you’ll still find one important precaution to take when cooking under pressure: adding water. Water and pressure cooking go hand in hand. In fact, it’s water that helps generate the high-pressure environment that makes your food cook faster.
Most pressure cooker instructions state a minimum amount of water required for pressure cooking even a tiny amount of food. Inside the tightly sealed pressure cooker, the water is heated and eventually boils into steam. Since the steam cannot escape, it collects above the food. All those trapped water molecules increase the pressure inside the cooker.

Given what we know about the mechanisms surrounding the biological movement of substances, we can confirm that when two substances in a secondary active transport move in the same direction, it is called a symport.
A secondary active transport harnesses the electrochemical energy generated by its movement of one substance, to aid the movement of the other. These movements can be of two types, depending on the directions:

A student conducts an experiment to separate water into hydrogen and oxygen as shown below.
As a result the student collects 28.0 g of hydrogen and 224.0 g of oxygen. How many grams water did the student originally have involved in the experiment
The student originally has 252 grams of water in this experiment.
LAW OF CONSERVATION OF MASS:
The law of conservation of mass explains that matter (mass) can neither be created nor destroyed but can be changed from one form to another. This means that in a chemical reaction, the sum of the masses of the reactants must equate to the total mass of product(s). According to this question, a student conducts an experiment to separate water into hydrogen and oxygen. The student collects 28.0 g of hydrogen and 224.0 g of oxygen. Since hydrogen and oxygen are the constituent elements of water, the sum of their masses must equate the mass of water. Therefore, 224g of oxygen + 28g of hydrogen = 252g of water.Learn more at: https://brainly.com/question/24996173?referrer=searchResults
A 250. mL sample of oxygen is collected over water at 25 °C and 760.0 torr pressure. What is the partial pressure
of the oxygen? (Vapor pressure of water at 25°C is 23.8 mm Hg)
Answer:The mass of oxygen gas sample collected over water is 0.544 g.
The given parameters;
temperature of the oxygen gas, t = 25 °C
total pressure of the gas, P = 644 torr
volume of the gas, V = 500 mL
vapor pressure = 23.8 torr
molar mass of oxygen gas = 32 g/mol
The number of moles of the gas collected is calculated by using ideal gas equation as follows;
PV = nRT
where;
R is the ideal gas constant = 62.36 L.torr/mol.K
P is the pressure of the gas = 644 torr - 23.8 torr = 620.2 torr
T is the temperature of the gas = 25 + 273 = 298 K
V is the volume of the gas = 500 mL = 0.5 L
The number of moles of the gas is calculated as follows;
The mass of oxygen gas collected is calculated as follows;
m = 0.017 (32 g/mol)
m = 0.544 g
Thus, the mass of oxygen gas sample collected over water is 0.544 g.
Explanation:
The partial pressure of oxygen is; 760.0 torr - 23.8 torr = 736.2 torr.
What is partial pressure?We know that in a mixture of gases, the pressure that is exerted by each gas is called the partial pressure of the mixture.
In this case, we have the total pressure of the mixture as 760.0 torr and the vapor pressure of water as 23.8 mm Hg or 23.8 torr) at that temperature. Hence, the partial pressure of oxygen is; 760.0 torr - 23.8 torr = 736.2 torr.

complete the word equations below to show how the metals are extracted from their oxides: 1) tin oxide + carbon ---> .........? + .......? 2) lead oxide + carbon ----> ......? + ......?
Answer:
1.) Tin oxide + Carbon → Tin + Carbon monoxide.
2.) Lead oxide + Carbon → Lead + Carbon monoxide.
These equations show that the metals are being extracted by their oxides by heating with carbon. This is because the metals (Tin and Lead) are less reactive than carbon. Remember, extraction methods of metals are determined by their reactivity. Since the elements tin and lead are less reactive than carbon, the extraction process of heating with carbon is needed. Remember that when a metal heats with carbon, the carbon displaces the metal from the compound and removes the oxygen from the oxide. Leaving you with the metal and carbon monoxide.

Decanting
Filtration
Sifting
Answer:
Filtration, Sifting and Decanting
Explanation:
Heterogenous mixtures can be seperated by filtration and sifting (Also known as sieving). Sifting is the process of parting a mixture using a sieve. Sifting is used to separate solid mixtures that contain molecules of varying sizes. Filtration is the process of separating a liquid from an insoluble solid. A common example is using a funnel and a coffee filiter to seperate the liquide from the insoluable solid. Although there are many other methods for filtration. You can also separate mixtures by decantation. Decantation is the process of separating a liquid from a solid/liquid by removing the liquid layer at the top from the layer of solid/liquid below.
