Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigment. It takes place in the chloroplasts of the plant cells. During photosynthesis, carbon dioxide (CO2) and water (H2O) are converted into oxygen (O2) and glucose (C6H12O6) in the presence of sunlight and chlorophyll. This process can be summarized by the following equation:

6 CO2 + 6 H2O + sunlight energy → C6H12O6 + 6 O2

In this equation, sunlight, water, and carbon dioxide are the reactants, while oxygen and glucose are the products. Therefore, your labels would fit into this equation as follows:

Sunlight - provides energy for the reaction to occur.

Water - reacts with CO2 to produce O2 and glucose.

O2 - released into the atmosphere as a product of photosynthesis.

Sugar - produced as a product of photosynthesis.

CO2 - reacts with water to produce O2 and glucose.

Pedigrees can be used to understand the inheritance pattern of a trait. In the exposed example, this trait is coded by a gene that expresses complete dominance. Option B. Autosomal dominant.

A Pedigree is the representation of a family's history. This graph is used to track a trait through different generations, and analyze the inheritance pattern of a particular gene and its expression.

It is a tool used to understand how genes are transmitted from the parental generation to the descendants, and what are the probabilities of  inheriting them.

In the exposed example, we have a trait coded by an autosomal gene that expresses complete dominance. The dominant allele is the one coding for the trait.

Microbes passing across the placenta to the fetus is NOT an example of symbiosis.

E is the correct answer.

Two creatures maintaining a relationship with one another for mutual benefit is known as symbiosis. To receive food, organisms in symbiotic mode form a unique bond with specific other organisms. Symbionts are the biological entities that participate in this kind of connection.

Symbiosis is the process by which organisms coexist for their mutual and, hence, inherent benefits. The microbiome, or the commensal organisms that coexist with us, and the human have a symbiotic relationship.

The interaction between specific ant species and acacia trees is a prime example of symbiosis. The ants, which reside in the acacia tree's hollow thorns, work to defend the tree against herbivores by attacking any that try to consume its leaves or bark.

During volume changes in the thoracic cavity, the diaphragm is primarily responsible for changes in length.

The diaphragm flattens and tightens during inhalation, and the chest cavity widens. A vacuum is produced by the contraction, drawing air into the lungs. The diaphragm relaxes and assumes its dome-like form during exhalation, forcing air from the lungs. This implies that when the volume of the thoracic cavity changes during inhalation and exhalation, the diaphragm plays a vital role in length.

The external intercostal muscles, internal intercostal muscles, innermost intercostal muscles, sub-costalis, and transversal thoracic are the five muscles that make up the thoracic wall. During respiration, the volume of thoracic cavity is predominantly altered by these muscles.

The condition is caused by the occlusion and abdominal distension of a lumens, which results in reduced blood flow, ischemic, and bacterial invasion is known as Appendix.

Appendiceal lumen occlusion is frequently the etiology of appendicitis. This may result from an appendicolith (appendix stone). The precise cause of acute pancreatitis is frequently unknown. Bacteria accumulate in the appendix as a result of obstruction of the appendiceal lumen, resulting in acute inflammation, perforation, and abscess formation. Despite being necessary, lymphoid hyperplasia causes swelling, localised ischemic, perforation, and the formation of a confined abscess or a true perforation with subsequent peritonitis.Appendicitis is brought on by an obstruction results in small vessel occlusion, lymphatic stasis, and a rise in luminal and intramural pressure. When blocked, the appendix begins to swell and fill with mucus. As lymph and vascular damage progresses, the appendix wall turns ischemic and necrotic.

Artificial photosynthesis is the process of using synthetic materials and processes to replicate the process of photosynthesis, which occurs naturally in plants and other photosynthetic organisms. In natural photosynthesis, solar energy is captured by photosynthetic pigments, such as chlorophyll, and used to convert carbon dioxide and water into oxygen and glucose (a type of sugar).

In laboratory tools, artificial photosynthesis can be achieved using a variety of techniques and materials. Some common approaches to artificial photosynthesis in the laboratory include:

Photocatalysis: This involves using a catalyst, such as titanium dioxide, to facilitate the conversion of carbon dioxide and water into oxygen and organic compounds, such as glucose, using light energy.

Artificial photosynthetic membranes: These are thin, synthetic membranes that are designed to mimic the structure and function of natural photosynthetic membranes, such as those found in chloroplasts. They can be used to capture and convert light energy into chemical energy, and can be modified to optimize the efficiency of the photosynthetic process.

Electrochemical cells: These are devices that use an electrical current to facilitate the conversion of carbon dioxide and water into oxygen and organic compounds, such as glucose. They can be designed to mimic the natural photosynthetic process, and can be modified to optimize the efficiency of the conversion.

Artificial photosynthesis in the laboratory can be used for a variety of purposes, including the production of renewable energy, the synthesis of chemicals and fuels, and the development of new materials.

Atherosclerosis is a complex and progressive disease that involves the accumulation of cholesterol, inflammation, and the formation of plaques, ultimately leading to narrowing of arteries and increased risk of heart attacks and strokes.

The process of atherosclerosis starts when the endothelial cells, which form the inner lining of the arteries, become damaged due to various factors such as high blood pressure, smoking, or diabetes. The damaged endothelial cells release molecules that attract white blood cells called monocytes to the site of injury.

The monocytes then enter the intima of the artery wall and differentiate into macrophages, which engulf and digest the accumulated cholesterol in the intima. However, over time, the macrophages become overloaded with cholesterol and die, releasing their contents into the intima. This triggers an inflammatory response, and more monocytes and macrophages are recruited to the site of injury.

The accumulation of cholesterol and other lipids, along with the dead macrophages and other cellular debris, form a fatty streak in the intima. The fatty streak can grow and progress into an atherosclerotic plaque, which is a complex structure that consists of a lipid-rich core, a fibrous cap, and an inflamed and necrotic core.
