which molecule is important in regulating cell membrane fluidity?
Answer:
cholesterol plays a distinct role in determining membrane fluidity.
Cholesterol has a specific impact on how fluid a membrane is. With their polar hydroxyl groups adjacent to the hydrophilic head groups of the phospholipids, cholesterol molecules enter the bilayer.
How does cholesterol regulate cell membrane fluidity?The phospholipid bilayer's random distribution of cholesterol molecules aids the bilayer's ability to remain fluid under a variety of environmental conditions.
Cells control membrane fluidity by modifying the lipid composition of the membrane. A lipid bilayer's fluidity fluctuates according to temperature. Lipid bilayers become more fluid, porous, or leaky at increasing temperatures (like butter melting on a hot day).
Cholesterol makes the cell membrane less fluid at higher temperatures and more fluid at lower temperatures.
Therefore, cholesterol is the chemical in the plasma membrane that has an impact on the fluidity of the membrane.

6. The Edwards Plateau in west-central Texas is home to a diverse group of bats, reptiles,
and birds. How does the biodiversity of the Edwards Plateau affect the sustainability of local
ecosystems?
A. The variety of interactions among the different species helps the ecosystems remain
sustainable.
B. The variety of interactions among the different species prevents the ecosystems from being
sustainable.
C. The uniformity of interactions among the different species prevents the ecosystems from
being sustainable.
D. The uniformity of interactions among the different species helps the ecosystems remain
sustainable.
Answer:
A.
Explanation:
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

According to Kepler's second law of motion, which statement describes the area
swept out py a line between a planet and the sun?
It is constant if the planet moves at a constant speed.
O It increases as the planet moves away from the sun.
O It is constant for equal times.
OIt increases as the planet approaches the sun.
Answer: It is constant for equal times
Explanation: Just did the assignment
According to Kepler's second law of motion it is constant for equal times. The correct option is C.
What is Kepler's law?Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, characterize the orbits of planets around the Sun.
The speed of a planet in an elliptical orbit around the Sun is described by Kepler's second law of planetary motion.
It states that a line drawn among both the Sun as well as the planet shuffles equivalent regions in equal amounts of time.
As a result, the planet's speed increases as it approaches the Sun and declines as it fades away from it.
Kepler's laws of planetary motion represent a watershed moment in the transformation from geocentrism to heliocentrism.
They establish the first quantitative link among the planets, together with Earth. They also represent a time when the important questions of the day were changing.
Thus, the correct option is C.

in the late 1980's scientists discovered a new fossil skeleton that changed their thinking about the events leading to life on land. This new fossil
had legs and feet, but ankles that were too weak to support it's weight on land. It had lungs and gills, but the rib cage was too short to prevent
the chest cavity from collapsing when the animal was on land. These structures suggested that limbs evolved before retrapods moved onto
land. What is the name of this new fossil skeleton?

Mannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol nonfermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol fermenter, a nonhalophilic mannitol fermenter, and a halophilic mannitol nonfermenter. Thus, the medium is acting as a __________ medium.
Mannitol salt agar can act as both a selective and differentiating medium. A selective medium is one in which inhibits the growth of a particular organism, and allows others to thrive in said conditions. In this case, MSA favors halophilic organisms. MSA is also a differentiating medium because of the mannitol content. Mannitol is a sugar and mannitol fermenters, like s. saprophyticus, use mannitol and release acid as a byproduct. The pH indicator within the agar changes from red to yellow.
