When sodium azide (NaN3) decomposes, it produces nitrogen gas (N2) and sodium metal (Na) as the other product:

2 NaN3(s) → 2 Na(s) + 3 N2(g)

The balanced chemical equation for this reaction indicates that the other product formed is sodium metal (Na). This is because the mass and charge are balanced on both sides of the equation.

Furthermore, sodium is an alkali metal and is highly reactive, making it a plausible product of a chemical reaction. Additionally, sodium is known to react with water to produce hydrogen gas and an alkaline solution, which can explain why the residue left after airbag deployment is often a white powder or a yellowish substance, which is the alkali metal hydroxide formed from the reaction of the sodium with moisture in the air.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Answer: The Krebs cycle

Explanation:

Answer:

as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

Answer:

Explanation:

Using water efficiently means using it wisely and not wasting it. When we use water more efficiently, we reduce the amount of water we consume, which helps to conserve water resources. This is important because water is a limited resource, and by using it efficiently, we can ensure enough water is available for future generations.

By using water more efficiently, we can also protect the environment. Water is essential for many ecosystems and habitats, and by conserving water, we can help maintain the balance of these ecosystems. Additionally, using water efficiently can reduce the need for energy-intensive water treatment and distribution processes, which can help reduce greenhouse gas emissions and mitigate climate change.

So, using water more efficiently helps protect the environment but also helps conserve water resources for the future.

There are two types of cell transport: Active Transport and Passive Transport. The active transport uses energy for the transferring of the substance from outside the cell to inside the cell (sometimes vise versa). The passive transport does not spend energy to transport substances through the cell membrane.

Active transport moves larger molecules and charged molecules while passive transport moves smaller charged molecules and non-polar molecules (except water).

Examples of active transport are the pump transport (Sodium-Potassium Pump) and Vesicle Transport (Exocytosis and Endocytosis). Examples of passive transport are simple diffusion, osmosis, and facilitated diffusion.

Specific examples:

> Molecular pump = Sodium-Potassium Pump = The sodium-potassium pump uses carrier protein to exchange the sodium and potassium across the cell membrane. This pump regulates the concentration gradient inside the cell.

> Exocytosis = elimination of waste products (like carbon dioxide and nitrogenous compounds) out of the cell = The cell makes a secretory vesicle that infuses with the cell membrane and then, expels the waste products outside of the cell.

>Endocytosis = Phagocytosis = Phagocytosis is an example of endocytosis that engulfs larger substances by forming vesicles.

>Simple Diffusion = transfer of oxygen = Oxygen freely diffuses across the cell membrane. It is observed very closely in the air sacs of the lungs.

>Osmosis = transfer of water in and out of the cell = Water is a partially charged molecule and it can pass through the hydrophobic parts of the cell membrane because of its small size.

>Facilitated diffusion = Glucose transport = Glucose is a large molecule and is carried into the cell by the glucose transporters. Sometimes, the transport of glucose is paired with another molecule.

The process of digestion begins in the mouth when you eat a meal or a snack.  Your eating and drinking habits may be impacted by oral cancer and its treatment. You could experience swallowing issues, taste alterations, weight loss, and dry mouth.

Dysphagia, the medical word for "swallowing difficulty," can be brought on by the tumor itself (often in head and neck malignancies), which stops or narrows the food channel, or it might result from a treatment-related adverse effect.

The oropharynx and mouth are both affected by oral cancer. An oral cancer patient may experience serious eating issues such as loss of appetite, diarrhea, constipation, nausea, vomiting, blistered mouth or throat tissues (mucositis), dry mouth (xerostomia), changes in taste, and fatigue because the healthy cells that are damaged include those in the mouth or digestive tract.
