The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP
Answer:
ADP
Explanation:
Your question: The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP
My answer: ADP
Why is my answer correct?
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?
S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.
S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.
In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.
It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.

The mitochondria
The Krebs cycle or citric acid processes in the mitochondrial matrix yield a substance called NADH. Adenosine triphosphate is then produced from NADH by enzymes included into the mitochondrial inner membrane (ATP).
What is the main role of mitochondria in nutrient energy?Organelles, or “tiny organs,” are what mitochondria are. They generate ATP (adenosine triphosphate), a chemical that is used by the cell to power the various tasks it must perform, as a source of energy.
The creation of cellular ATP by oxidative phosphorylation is undoubtedly one of the activities of mitochondria, but they also play significant roles in ion homeostasis.
Various metabolic pathways, apoptosis and programmed cell death, as well as the production and consumption of ROS.
Therefore, mitochondria transform nutrient material into an energy form that is used by the cell.

What is fertilizer?
Outside matter added to the ground to help plants grow
Oxygen and water added to the ground
Inorganic matter
Nitrogen-fixing bacteria in the ground
Answer: 3
Explanation:
Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.
