“Does feeding animals a high-protein diet build muscle?”
Feeding animals, a high-protein diet will do more harm than good.
If I eat a high-protein diet, then I will spend too much money. High-protein diets are too expensive.
If animals are fed a high-protein diet, then it will not cause them to build muscle.
High-protein diets are not healthy for animals.
High-protein foods are important for building muscles. So, if animals are fed a high protein diet, then this will not cause them to build muscles. Thus option C is correct.
What is a high-protein diet?A high-protein diet is a diet in which 20% or more of the daily calorie intake comes from protein. A high-protein diet helps increasing the muscular mass.
Various animal and plant sources provide the necessary building blocks of muscles i.e., MPS (Muscle Protein Synthesis). An MRI can be performed to check the muscle mass percentage.
Therefore, correct option is C.

Which of the following is likely to describe a metabolic reaction where the net delta G value is positive?
spontaneous or non-spontaneous
catabolic or anabolic
positive delta E or negative delta E
The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.
What are metabolic reactions?The Gibbs free energy difference between a reaction's products and reactants is known as delta G.
The response is spontaneous if Delta G is negative, non-spontaneous if it is positive, equilibrium if it is zero, and non-spontaneous if it is negative. If dH is positive and dS is negative according to the equation dG = dH - dS*T, then delta G is positive.
Delta G is negative if dH is negative and dS is positive. It depends on the temperature at which the reaction is taking place whether dH and dS are both positive or both negative.
Therefore, The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.

The periodic table is a table that arranges the elements based on increasing atomic number into horizontal rows and vertical columns.
The properties of the elements in the periodic table show a regular variation across the vertical columns and the horizontal rows. This variation in property is known as periodicity.
The vertical columns are called groups or families whereas the horizontal rows are called periods.
The periods determine the number of valence shells in an element while the groups determine the number of valence electrons, and hence reactivity of the element.
Across a period from left to right, the elements change from metals to non-metals.

Farmers need to adapt precision agriculture to increase the crop yield, productivity and bring the expenses in control.
For every farmer, agricultural retailer, and agronomist, technology has evolved into a necessary component of conducting business. No one should be shocked by the high rate of technological use in agriculture. Farming requires a lot of land and effort. Farmers are compelled to employ technology to boost productivity and control expenses.
Precision farming and precision ag are other terms for precision agriculture. The best approach to grasp precision agriculture may be to see it as anything that makes farming more precise and regulated when it comes to producing animals and growing crops.
The utilization of information technology and a variety of tools, including GPS guidance, robots, control systems, drones, sensors, telecommunications, autonomous vehicles, GPS-based soil sampling, variable rate technology, automated hardware, and software, is a crucial aspect of this farm management strategy.

2H₂O2 -> 2H₂O + O₂
2H₂O + O₂->> 2H₂O2
The reaction 2H₂O2 -> 2H₂O + O₂ shows Catalase reaction. The correct option is 3.
What is Catalase reaction?The catalase reaction encompasses the breakdown of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen (O₂).
The enzyme catalase facilitates this reaction. The reaction is represented by the equation: 2H₂O₂ -> 2H₂O + O₂.
This means that when two molecules of hydrogen peroxide react, two molecules of water and one molecule of oxygen are formed.
The presence of the enzyme catalase, which speeds up the reaction and allows it to occur under normal physiological conditions, makes this reaction possible.
The Catalase reaction is an important process that aids in the breakdown of harmful hydrogen peroxide into harmless water and oxygen in living organisms.
