Which of the following substancces does NOT bioaccumulate and, therefore, is NOT biomagnified through a food chain in the environment?
A. DDT
B. mercury
C. lead
D. oxygen
The substance that does not bioaccumulate and therefore, is not bio-magnified through a food chain in the environment is oxygen (option D).
What is biomagnification?Biomagnification is the process, in an ecosystem, in which a higher concentration of a substance in an organism is obtained higher up the food chain.
The contaminants that can be bio-magnified in a polluted environment are usually heavy metals such as mercury, arsenic, and pesticides such as polychlorinated biphenyls and DDT.
Oxygen is a naturally occurring gas that is beneficial in the environment, hence, does not bioaccumulate in living organisms as it is readily used.
Therefore, oxygen does not bioaccumulate and biomagnify through a food chain in the environment.

Changes in pH alters the enzymatic activity by modifying electric charges
A True
B) False
Changes in pH alters the enzymatic activity by modifying electric charges hence the statement is False.
Briefing:The activity of the enzyme slows down and finally stops when the pH value deviates from the optimum range. The substrate houses the enzyme's active site.
What generates an electric charge?When electrons are added to or taken away from an object, an electrical charge is produced. An object acquires a negative charge when electrons are introduced to it because electrons have a negative charge. An object acquires a positive charge when its electrons are removed.
What is an example of an electric charge?The ability to conduct electricity is a characteristic of many fundamental, or subatomic, components of matter. As an illustration, protons and neutrons both have positive charges but electrons have a negative charge.

how is gallium obtained and separated from nearby substances?
PLLSSS HELP
Gallium(III) hydroxide in potassium hydroxide solution can be electrolyzed to produce the metal.
What is the purpose of gallium?It is crucial for Blu-ray technology, mobile phones, blue and green LEDs, and touch switches with pressure sensors. Most metals are easily alloyed with gallium. Particularly in low-melting alloys, it is employed. Because of its high boiling point, it is perfect for recording temperatures that would cause a thermometer to vaporize.
Does gallium react with gold?Furthermore, because gold and gallium can produce alloys with low melting points, it is not surprising that a significant amount of the underlying GaAs dissolves during the alloying cycle. The end result is a contact with good electrical characteristics but one that is quite atypical morphologically and challenging to duplicate.

The density of the unknown liquid sample will be 4.0 g/.mL
What is density?The density of a substance is the ratio of the mass of the substance to its volume.
This is mathematically expressed as:
Density = mass/volume.
In this case:
Volume of unknown liquid sample = 24.0 mL
Mass of unknown liquid sample = 6 g
Density of the unknown liquid sample = 24.0/6

How does an organism composed of relatively small cells have an advantage over one made of larger cells?
The surface area-to-volume ratio of a cell diminishes with growth. If the cell were in the form of a cube, the same reasoning would hold true. The plasma membrane won't have enough surface area if the cell enlarges too much to accommodate the volumetric rise in diffusion rate.
In other terms, a cell gets less effective as it develops. One technique to increase efficiency is to divide, while another is to create organelles with specific functions. Smaller single-celled creatures have a high surface-to-volume ratio, which enables them to rely on material and oxygen diffusion into the cell (and waste diffusion out) to survive. This method can be more effective if the objects have a larger volume to surface area ratio. Larger animals need specialized organs (such as the lungs, kidneys, and intestines) that efficiently increase the surface area accessible for exchange activities, as well as a circulatory system to transport materials and heat energy between the organism's surface and core.

The theory of evolution proposed by Lamarck tells us that living beings were not created from nothing but were the result of evolution from much simpler beings.
How does evolution occur according to Lamarck?These evolutionary characteristics were obtained when an individual adapted to a change in situation or environment that occurred through a habit. He says then that evolution occurs by characters acquired through life, these are passed to its germ line and so little by little the evolution is taking place.
This theory was not taken into account since it is impossible to transfer acquired characteristics from the somatic line to the germ line. Giving then as erroneous this theory proposed by Lamarck.

What is the research about?A population's or phenomenon's characteristics are described through descriptive research. It does not provide an explanation for when, how, or why the features developed. Instead, it answers the "what" query.
With a correlational research design, correlations between two variables—or more—are examined without any of the variables being under the researcher's direct control or manipulation. It is a form of quantitative study that is not experimental.
A study that carefully follows a scientific research strategy is called experimental research. It consists of a hypothesis, a controllable variable, and variables that can be measured, calculated, and compared. Most crucially, controlled environments are used to conduct experimental research.
