Which of the following quotes best explains why Carson chose the title "Silent Spring" for her book?
"On the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves,
Ojays, wrens, and scores of other bird voices there was now no sound; only silence layover the
fields and woods and marsh."
"Along the roads, laurel, viburnum, and alder, great ferns and wildflowers delighted the
traveler's eye through much of the year."
"So it had been from the days many years ago when the first settlers raised their houses,
sank their wells, and built their barns."
"Then a strange blight crept over the area and everything began to change. Some evil spell
Ohad settled on the community: mysterious maladies swept the flocks of chickens; the cattle
and sheep sickened and died."
The title of Silent Spring, which conjures up a deteriorated environment, was inspired by the line from John Keats' poem "La Belle Dame sans Merci," "the sedge is wither'd off the lake, / And no birds sing."
What is meant by degraded environment?The term "environmental degradation" refers to the deterioration of the environment caused by the depletion of resources such as the quality of the air, water, and soil; the destruction of ecosystems; the destruction of habitats; the extinction of wildlife; and pollution. The term "environmental degradation" refers to the deterioration of the environment's quality as a result of natural disasters, poor land use, ambient pollution concentrations, and other processes and activities. Among the most common sources of water pollution include sewage from both public and private sources, pesticides, fertilizers, plankton blooms, silt, oils, chemical traces, radioactive substances, and others.

A. Hair on the body lies flat against the skin.
B. Blood vessels under the skin expand.
C. Sweat glands are turned on.
D. Muscles under the skin make body hair stand on end.
Thermoregulation: D. Muscles under the skin make body hair stand on end.
Why hairs of skin stand during thermoregulation?Thermoregulation means maintaining constant body temperature of 37 degrees Celsius. Through a number of physical mechanisms, the human body keeps its temperature at roughly 98.6°F (37°C). Shivering to increase body temperature, sweating to decrease it, and constricting or relaxing blood vessels to change blood flow are a few examples. An individual may overheat and develop hyperthermia if they are unable to control their body temperature. The inverse is also true: Hypothermia will result if the core temperature drops below a safe level. Both ailments have the potential to be fatal.
The skin's hairs aid in controlling body temperature. Each hair's erector muscle makes them stand straight when they're cold. Insulates by trapping a layer of warm air close to the skin.

A hygrometer would provide you with information based on your experience of feeling "wet & sticky" outside.
what is hygrometer ?
A hygrometer is a device that measures the quantity of water vapour in the air, soil, or restricted places. Humidity metres often rely on measurements of other factors such as temperature, pressure, mass, or a mechanical or electrical change in a substance when moisture is absorbed. These measurable values can be used to calculate humidity using calibration and computation. To monitor humidity variations, modern electronic devices employ the temperature of condensation (called the dew point) or changes in electrical capacitance or resistance. Leonardo da Vinci constructed a primitive hygrometer in 1480. During the 1600s, major advances were made; Francesco Folli constructed a more practical version of the apparatus.

Diffusion of a substance across the cell membrane may be influenced by all of the following except
O its charge of the substance. O its concentration gradient.
O its lipid solubility. O the availability of ATP. O the presence of membrane channels for the substance.
Diffusion of a substance across the cell membrane may not be influenced by the availability of ATP.
Moving molecules along a concentration gradient is referred to as diffusion. Each and every living thing goes through this crucial phase. The flow of materials into and out of cells is aided by diffusion.
The most fundamental way for molecules to cross the plasma membrane is through passive diffusion.Simply said, a molecule diffuses through the phospholipid bilayer during passive diffusion, dissolves in the aqueous solution on the other side of the membrane, and then diffuses back through the bilayer.
When molecules are moving over concentration gradients in cells, some can do so directly across the lipid section of the membrane, while others must go through membrane proteins, which is a process known as facilitated diffusion.

Noncoding DNA sequences are parts of an organism's DNA that do not encode protein sequences, according to the fields of genomics and allied sciences. While some non-coding DNA is not transcribed or gives rise to RNA transcripts with uncertain functions, some non-coding DNA is transcribed into functional non-coding RNA molecules (such as transfer RNA, ribosomal RNA, and regulatory RNAs).
Species differ substantially in the quantity of non-coding DNA they contain. Since a significant fraction of noncoding DNA at first had no recognised biological purpose, it was occasionally referred to as "junk DNA," especially in the lay press.
