Wise dominion over the process of photosynthesis can be exercised in such a way that all the people and animals can benefit from it and we can use it correctly.

Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are formed by the reaction of carbon dioxide and water.

Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for producing and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

Urea is formed through a process called urea synthesis, which occurs in the liver. During this process, the liver combines two molecules of ammonia with one molecule of carbon dioxide to form urea. This reaction is catalyzed by the enzyme urea synthase and requires the presence of energy in the form of ATP. The urea synthesis process helps to remove excess nitrogen from the body, as ammonia is a toxic waste product that is produced during the breakdown of proteins. The urea is then excreted from the body through the urine

Urea is synthesized in the body of many organisms as part of the urea cycle, either from the oxidation of amino acids or from ammonia. In this cycle, amino groups donated by ammonia and L-aspartate are converted to urea, while L-ornithine, citrulline, L-argininosuccinate, and L-arginine act as intermediates.

Washing soda can be added to water to dissolve any lingering hardness.

The presence of dissolved calcium and magnesium ions contributes to the hardness of water. Temporary hardness and permanent hardness are the two different types of water hardness. Boiling the water makes the dissolved calcium carbonate precipitate out as calcium carbonate, which can be used to remove temporary hardness. On the other hand, permanent hardness is brought on by the existence of dissolved calcium and magnesium sulfates and cannot be eliminated by boiling.

Water hardness can be eliminated permanently with washing soda, sometimes referred to as sodium carbonate. By interacting with the dissolved calcium and magnesium ions to create insoluble precipitates, it softens the water.

A,C and D options are not correct. Chlorine is used to disinfect water, but it doesn't remove hardness. Potassium permanganate is a strong oxidizer and can be used as a disinfectant and treatment for certain water impurities, but it also doesn't change the hardness of water. Bleaching powder is used as a disinfectant and oxidizer, but it doesn't have a role in changing the hardness of water.

Organisms are classified into kingdoms based on a variety of factors, but primarily on the basis of structure, behavior, size, and habitat. So all the given options are correct.

First and foremost, structure is the most important factor in determining the kingdom to which an organism belongs. Morphology, or the physical structure of an organism, plays a vital role in the classification process. For example, the vast majority of animals are classified as members of the Animalia kingdom, due to their possession of a backbone and other characteristics that distinguish them from other organisms.

Behavior is also used as a criterion for kingdom classification. Organisms are grouped into different kingdoms based on the behaviors they exhibit, such as their mating habits, feeding behavior, and even their social organization. For instance, many fish, birds, and mammals are grouped together in the Animalia kingdom due to their similar behaviors.

Size is another factor that is taken into consideration when classifying organisms into kingdoms. Generally, larger organisms are grouped in the Animalia kingdom, while smaller organisms, such as bacteria and protists, are placed in the Protista kingdom.

Lastly, the habitat of an organism is also used to assign it to a certain kingdom. Different kingdoms are characterized by certain habitats, such as the Animalia kingdom is associated with land-based habitats. Thus, when an organism is found to live in a certain habitat, it is generally assigned to the kingdom associated with that habitat.

The enzyme that can proof-read the DNA molecule during the process of DNA replication is called DNA polymerase. DNA polymerase is responsible for adding nucleotides to the growing strand of DNA during replication.

Some DNA polymerases, such as DNA polymerase III and DNA polymerase I, have a proofreading exonuclease activity that allows them to remove any nucleotides that are not correctly paired with the template strand during replication.

The proofreading exonuclease activity of DNA polymerase works by recognizing mismatches between the nucleotides that have been added to the growing strand and the template strand. When a mismatch is detected, the exonuclease activity of the enzyme removes the incorrectly paired nucleotide, allowing the polymerase to add the correct nucleotide in its place.

This proofreading activity increases the accuracy of DNA replication, reducing the number of errors made during replication to approximately 1 in 10^5 nucleotides.

Yes (kind of), because even though we do not use the sun as directly as say plants, we still rely on the sun on a daily basis, however we don't necessarily get our energy from it, like plants do.

The sun produces light as well as heat, also known as solar energy. This makes it possible for life to exist on Earth, and we can use solar energy to power a wide variety of useful things, however sun/solar energy is not the only way to get electricity.

As we know, plants need sunlight to grow, although humans don't grow by being exposed to sunlight, sunlight helps grow plants which animals, including humans, need for food as well as oxygen they produce.

Most livestock we eat, cows for example, need plants to survive and many people eat meat, and even if you don't you'd eat plants which, once again, need sunlight to grow. Also, without heat from the sun, Earth would freeze.

In this situation, the time of death (TOD) can be estimated by examining the evidence of the body's condition. Rigor mortis, the stiffening of muscles after death, is one of the most reliable indicators of the approximate TOD. The fact that the body of the 16 year old male exhibited rigor in the legs, but not in the upper torso, implies that the body had been in the car for a period of time during which it could have been affected by the ambient temperature.

Rigor mortis usually sets in 2-6 hours after death, and its effects can be seen in the body's muscles for up to 12 hours. As the ambient temperature in the car was 102°F, the body's muscles would have stiffened due to the heat, leading to an accelerated onset of rigor mortis. This means that the TOD for this situation is likely to have been within 2-6 hours of the body being discovered, assuming that the ambient temperature had been stable for the duration of the body being in the car.

Throughout embryonic development, a single group of cells, known as the ectoderm, differentiates to form a variety of specialized cells that make up the body of a completed organism.

One example of this is the development of the eyes, which contain clear, transparent lens cells. In order to understand how a single group of cells can differentiate to form such diverse components, it is important to understand the underlying cellular processes that drive this differentiation.

First, the ectoderm of the embryo undergoes a process known as gastrulation. During this process, the ectoderm begins to fold and divide, producing three distinct layers of cells known as the endoderm, mesoderm, and ectoderm.

As the cells differentiate, they begin to express different proteins on their surfaces which become the basis for further cell-to-cell interactions and signaling. This process is known as inductive signaling and is responsible for the development of the specialized cells in the embryo.

The inductive signaling process is responsible for the formation of the transparent lens cells in the eye. As the ectoderm begins to differentiate, certain cells in the mesoderm will receive signals from the ectoderm to begin the process of lens formation. The lens cells then produce proteins that induce the formation of other specialized cells in the eye, such as the cornea and the iris.
