Which of the following describes the range of a butterfly?
Group of answer choices
A. throughout the US and Mexico
B. approximately 4 butterflies die each day
C. the milkweed plant
D. 10,000 butterflies/acre during the breeding season
The option that describes the range of a butterfly is the milkweed plant. Thus, the correct option is C.
What is species range in ecology?A species range may be defined as an area where a particular species can be found during its lifetime.
The population of butterflies may migrate or hibernate in the locality of the milkweed plant itself. They take the nutrients required for growth and reproduction from the milkweed plant.
Therefore, the correct option is C.

Two sound waves are moving through a medium at the same speed. If wave x has a greater frequency than wave y, then wave x
Correct Question:
Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X
A. has a lower amplitude.
B. has a shorter wavelength.
C. has a longer wavelength.
D. has a greater amplitude.
Answer:
C. has a longer wavelength.
The basic equation of frequency and speed are
velocity = frequency x wavelength
When both waves' velocities are the same then
v1 = v2
f-1 x wavelenght-1 = f-2 x wavelenght-2
Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

How are decreasing amounts of sea ice particularly harmful to mother polar bears and their cubs?
Answer:
Every winter, Arctic sea ice grows around the pole, its frozen tendrils threading along northern coasts. Right now sea ice has just passed its peak coverage for the year, and will begin to shrink with the coming of spring. It’s a crucial time for polar bears, whose food supply is inextricably linked to sea ice.
And in recent decades, sea ice has been shrinking faster than ever. According to the National Snow and Ice Data Center, 2019 has the seventh-lowest sea ice cover in the Arctic since they began collecting satellite data 40 years ago.
This year “doesn't break any records, but it's the trend that matters,” says University of Alberta polar bear scientist Andrew Derocher. “The downward trend in Arctic sea ice across all months is the concern,” he says, and “now we wait to see what spring conditions bring.” (Read more about global warming’s link to polar bears.)
A cold spring allows ice to linger, giving polar bears easier access to one of their favorite foods: seals. A warm spring cuts short the availability of their food super-highway....

Your alien friend from planet Xenon is visiting and wants to learn how to breed pea plants. You show your friend a recent batch of pea plants with purple flowers that you grew by crossing plants that had purple flowers with plants that had white flowers. Your Alien friend is confused as to why all your plants have purple flowers. How would u explain in the simplest way possible what happened? Hint: think about parents passing on alleles and dominant vs recessive. ANSWER ASAP FOR BRAINLEIST
Answer:
You have a trait (plant color) and you have two possible outcomes for it (purple and white). You know that some alleles for white were present in one of the parent plants, so you know they must be present in the offspring too. But they're expression is covered up by the purple alleles from the other plant, so you know that purple is dominant to white.

What process creates stalagmites? Group of answer choices Rivers carrying rocks down a mountain Windblown sand shaping large rocks Minerals being deposited as water drips Glaciers pushing large rocks
Answer:
Minerals being deposited as water drips.
Explanation:
Stalagmites grow on the floor of a cave. The process that creates them starts with the filtration of rainwater drops through the rock picking gases and minerals, amongst these ones is calcite. When the drops containing these elements pass through the rock and are in contact with the air, a chemical reaction happens. As a consequence, the calcite precipitate on the floor of the cave. This process has to happen many times to form a stalagmite.

What does pyruvate with O2 go to?
Answer:
In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.

A canyon is a small, deep valley with cliff-like sides. The Spanish word caon, which meaning “tube” or “pipe,” is where the term “canyon” originates. Thus, option A is correct.
What Canyons type of land features represented?A deep valley that has been carved into the surface of the earth over a long period of time by erosion from a flowing river is referred to as a canyon.
It is also referred to as a gorge and typically features rocky cliffs and very steep walls. One of the most well-known instances is the Grand Canyon, which the Colorado River carved out.
Canyon: A deep valley with steep walls and a V-shape created by a river slicing through hard rock. These valleys are common in the upper reaches of rivers, where the stream's fast, strong current rapidly digs the valley. Gorges are smaller valleys with a similar aspect.
Therefore, Although “gorge” is frequently used interchangeably with “canyon,” a gorge is nearly invariably narrower and steeper.
