which is an example of source pollution that may negatively affect the atmosphere
Answer:
Smokestacks, discharge pipes, and drainage ditches.
Explanation:
Examples include smokestacks, discharge pipes, and drainage ditches. Factories and power plants can be a source of point-source pollution, affecting both air and water. Smokestacks may spew carbon monoxide, heavy metal, sulfur dioxide, nitrogen dioxide, or “particulate matter” (small particles) into the air.

In which of the following situations does the cell use active transport?
Answer: The correct option is B. Sodium ions move into the cell from areas of lower concentrations.
Explanation:
Active transport can be described as a process in which molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Energy is required for the process of active transport to occur.In the option B, sodium ions are moving into the cell from areas which have a low concentration of sodium i.e against the concentration gradient. Hence, option B tells that the sodium ions will move inside the cell by the process of active transport.

is
There are
not alive. What do these two statements imply about cells?
A. Cells come from preexisting cells.
• B. Cells are the basic units of life.
®
C. Most organisms are made up of cells.
• D.
Bacteria are single-cell organisms.
SUBMIT
Answer:
b
Explanation:
Explanation:
A cell is the basic unit of life which carries all the biological molecules inside the membrane to keep an organism alive. It is the structural and functional unit of life of which all living organisms are made of.
Living organisms can be single-celled or multi-celled as cells can attach, interact with each other forming complex tissues dividing the responsibility to different tissues which further form organ and organ system of an organism like the digestive system. So, cells form the basic unit of biology.

Answer:
How can you determine experimentally whether a bacterium is a psychrophile or a mesophile? incubate two cultures, one around 10°C and the other around 35°C. If it grows in the lower temperature incubator, it is a psychrophile. If it grows in the higher temperature incubator, it is a mesophile.
Explanation:
Answer:
incubate two cultures, one around 10°C and the other around 35°C. If it grows in the lower temperature incubator, it is a psychrophile. If it grows in the higher temperature incubator, it is a mesophile.

Scientists are interested in measuring the effect of pollution on the water quality of a stream. They will use observations of various bottom-
dwelling insects, or macroinvertebrates, collected in the stream as indicators of the physical, chemical and biological conditions within the
stream. Which of the following best describes why macroinvertebrate sampling can be used to assess the overall health of a stream?
Macroinvertebrates live in an aquatic ecosystem for a long enough time to show the chronic effects of pollutants, and many
tend to remain in the same area throughout their life span
B
Macroinvertebrates migrate long distances to feed or reproduce, and they have a low tolerance to pollutants.
Macroinvertebrates are top predators, so they are often used in determining whether toxins will bioaccumulate or
biomagnify in an aquatic environment
D
Macroinvertebrates can be collected to evaluate the effect of various test parameters such as dissolved oxygen, nitrites, and
pH at the time that the sample was taken

Scientists are interested in estimating the effect of pollution on the water grade of a stream. They will use statements of various bottom-dwelling insects, or macroinvertebrates, contain in the stream as hands of the physical, chemical, and biological conditions within the stream, Thus option "C" is correct.
What are some of the advantages of biological monitoring of macroinvertebrates in a stream?Macroinvertebrates merge the marks of short-term environmental deviations.
Most species have a complicated life cycle of about one year or more. Liable life phases will respond fast to stress; the overall community will respond more slow.
Thus, option "C" is correct, Macroinvertebrates are top predators, so they are often used in defining whether toxins will bioaccumulate or biomagnify in an aquatic environment.

Salt is most likely to be mined using which mining technique?
A.) Mountaintop removal
B.) Solution mining
C.) Placer mining
D.) dredging
Answer:
B.) Solution Mining
Explanation:
Definintion: solution mining is mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water.
Sorry if it's wrong!
=> Solution mining is done by pumping water into subterranean salt deposits, found in many parts of the world, dissolving the salts and pumping the brine to the surface for drying and further use.
