The following diagram represents the reaction of methane with oxygen gas to form carbon dioxide and water.

The chemical reaction shown above takes place in a closed system. What is true about the system while the reaction occurs?

Answer:

X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm

Explanation:

A bacterium is a living thing that are majorly known for causing diseases but are important for human life.

A bacterium is also consist of several organelles such as cell wall, cytoplasm, flagellum,  bacterial DNA, cytoplasm, ribosomes and others.

The diagram shows three main organelles that are X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm. Flagella functions for the locomotion of the bacteria, bacterial DNA is a genetic material of the bacteria, and cytoplasm is a gel-like matrix composed of enzymes, water, nutrients and other waste material.

Hence, the correct answer is "X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm".

Answer:

The effects of climate change may be associated with the increased incidence of V. vulnificus infection

Explanation:

Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

Answer:

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

Fish die from lack of oxygen due to an algal bloom is a likely result of chemical water pollution. Therefore, option (B) is correct.

Chemical water pollution refers to the presence of harmful chemicals or substances in water bodies such as lakes, rivers, and oceans. These chemicals may come from various sources, including industrial processes, agriculture, and human activities. Common types of chemical pollutants in water include heavy metals, pesticides, oil spills, and toxic waste.

Chemical water pollution can have harmful effects on the environment and human health, including reduced water quality, contamination of aquatic life, and the spread of waterborne diseases. Preventative measures, such as proper waste disposal and treatment, are necessary to minimize chemical water pollution and protect water resources.

Answer:

Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.

Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

The difference between active and passive transports is that active transport requires ATP while passive transport does not. the correct option would be C.

Active transports are the movement of materials in and out of the cell that requires the expedition of energy. The energy is usually in the form of Adenosine Triphosphate (ATP).

Active transport is unlike passive transport because the latter requires no energy. In other words, passive transports are spontaneous.

Active transport usually involves the movement of materials against their concentration gradients while passive transport is the complete opposite.

Examples of active transport include the sodium-potassium pump, movement of amino acids in the intestinal tracts of man, etc while examples of passive transport include simple diffusion of oxygen to the alveolar walls in the lung.

Answer and Explanation:

Petroleum and coal are fossil fuels.  The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Answer and Explanation:

Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.

                                                Zn + H2SO4       ZnSO4 + H2
