The correct statement would be option C. Both of these are gametes and or sex cells, and are produced during the process of meiosis. Since meiosis tends to reduce the number of chromosomes present in producing the gametes, so that upon fusion we can obtain a correct diploid or other polyploid organism. This is why it is produced via meiosis.
A spontaneous reaction is one that favors the creation of products under the reaction's current conditions.
What is spontaneous reaction?
A spontaneous reaction is exergonic and has a negative delta G. The system's enthalpy, or total energy, must decrease and its entropy, or disorder, must rise for a chemical reaction to occur with a net release of free energy (- delta G). The energy needed for cellular function comes from spontaneous reactions.
What is importance of spontaneous reactions in the metabolism of a cell?
- Chemical reactions take place in steps to produce and break down complex molecules as part of cellular activities.
- While some of these chemical processes take energy to complete, others happen spontaneously and release energy.
- Cells must continuously produce additional energy to replace the energy spent by the numerous energy-intensive chemical reactions that take place all the time, just as living beings must continuously consume food to replenish their energy stores.
- The term "cell metabolism" refers to all of the chemical processes that occur within of cells, including those that use or produce energy.

Answer:</h3>
The goal of an engineer is to find ways to keep people safe, and to solve their problems efficiently and effectively. Every engineer has a goal, but not every engineer knows what it is. Fewer still don’t have a plan for getting there. Be exceptional—know your goals and make them happen. If you can do this, you’re already well on your way to an extraordinary engineering career.

Answer:
Anabolic reaction
Explanation:
Living cells undergo metabolic reactions from time to time. Metabolic reactions constitutes the series of building up and breaking down of molecules. The building up of larger organic molecules from smaller ones is referred to as ANABOLISM. A very vivid example of an anabolic process is the photosynthesis that occurs in the Chloroplast of plant cells.
In photosynthesis, plants combine inorganic carbondioxide (CO2) and water (H2O) to form a more complex organic molecule called glucose. Anabolic processes like photosynthesis usually require energy to build up the molecules, in the case of the photosynthesis, plants uniquely get this energy by trapping light energy from sun to power this process.
Answer:
From solutions that evaporate
Explanation:
Minerals can form in different ways. According to the question, minerals crystallize from a material dissolved in water when the solution evaporates. When a material dissolves in water, it forms a solution i.e. water + dissolved material.
The element constituents of the solution can aggregate to form a solid mineral, which will be left to crystallize when the solution undergoes evaporation i.e. liquid changes to gas. A very good example is when salt dissolves in water to form a salt water solution. When the water of this solution evaporates, salt crystals are left, which can crystallize to form minerals.
