Amy hikes down into the Grand Canyon to see Havasu Falls, a waterfall famous for its blue-green water and rock formations.
How does water shape Earth’s surface? What is the main way the hydrosphere interacts with the geosphere at Havasu Falls? Explain how this process forms waterfalls.
Basically when water goes over the earth it corrodes it and in that way shapes the earth's surface. The hydrosphere corrodes the gyoshere at Havasu Falls.
The hydrosphere is interacts with the geosphere at Havasu falls via Erosion. The erode of waterfalls softer surface of the rocks that leads to shaping the Earth's surface.
What is Geosphere?
The geosphere is the layer of Earth which consists of solid rock and other rocky materials. In contrast it could be said that the geosphere is a part of the physical, solid Earth which excludes hydrosphere (i.e. oceans, lakes, and rivers) or the atmosphere (the layer of gases that separates the ground from space).
The term geosphere is basically the the crust portion of earth, as the crust elucidates the outer layer of earth's rigid portion.
The geosphere is basically all about processes, the rock cycle processes consisting of metamorphism, melting and solidification, weathering, erosion, deposition, and burial, these constant process are responsible for the recycling of rocks on Earth between sedimentary, igneous, and metamorphic states.
Thus, the hydrosphere is interacts with the geosphere at Havasu falls via Erosion. The erode of waterfalls softer surface of the rocks that leads to shaping the Earth's surface.

4. What role do the muscles and blood vessels play in the negative feedback loop of thermoregulation?
A) integration centers B)sensors
C)stimuli
D)effectors
Answer:
D)effectors
Explanation:
Skeletal muscles constitute an additional effector in this feedback loop because they quickly contract in response to a drop in body temperature, hence option D is correct.
What is a negative feedback loop of thermoregulation?Blood flow is decreased, and the environment loses less heat as a result because blood vessels close to the skin constrict. Shivering helps the body produce heat, which raises body temperature.
The body starts to sweat when the hypothalamus senses that it is too hot, trying to bring the body's temperature back down to normal. Sweating will cease after the body temperature has returned to normal.
Therefore, the muscles and blood vessels play as effectors in the negative feedback loop of thermoregulation, hence option D is correct.

Answer:
B - Diabetes
Explanation:

Diabetes is a health problem that is not likely to be magnified by exposure to air pollution.
What is diabetes?This is a form of metabolic condition in which the pancreas produces very little insulin or the insulin generated cannot be utilized properly by the body.
Glucose is derived from the foods we consume. Insulin is a hormone that aids in the movement of sugar from the bloodstream into all of the body's cells so that it can be stored and used for energy. If the body does not create enough insulin, glucose builds up in the body, which is known as prediabetes.

Hypotonic, hypertonic, or isotonic?
Please help me answer this question!
Explanation:
if solute is 43% inside the cell then water is 57% (100%-43% = 57%)
outside; 100% - 60% = 40% water
it is hypertonic because water concentration is high inside the cell than outside, hence water flows to the outside of the cell.

The solar system has eight planets, the remaining four are outer planets, and four are inner planets, beyond the asteroid belt are the outer planets.
How do outer planets differ from inner planets?The term "Jovian planets" refers to gaseous outer planets. Terrestrial planets are the inner planets. While inner planets only have one to two moons, outer planets have a large number of moons.
Compared to outer planets, inner planets are located closer to the Sun. The size of the outer planets is greater than that of the inner planets.
The orbital periods of outer planets are longer than those of inner planets. Unlike inner planets, outer planets have a ring system.
Therefore, the four outer planets have a more extensive moon and ring systems, longer orbits and spins, and are made up mostly of gases and liquids.

In 1912, Alfred Wegener hypothesized that all the continents were once joined together in one giant landmass. This is known as the hypothesis of continental drift. Which of the following contained clues that led Wegener to his hypothesis?
Group of answer choices
a. land features, fossils, and climate
b. mid-ocean ridges, fossils, and climate
c. land features, fossils, and sea-floor spreading
d. mid-ocean ridges, fossils, and weather
Answer: c. Land features, fossils and sea floor spreading.
Explanation: First, climate and weather were not associated with Wege er’s reasoning.
Land features: an important clue for Wegener was in the current shapes of South America and Africa. Looking at them on a map, one can see their adjacent coastlines are almost a perfect fit.
Fossils: He noted that, for example, the same fossils appeared in Scotland and the east coast of North America
Sea-floor spreading: the discovery of seafloor spreading under the Atlantic Ocean gave Wegener a clue as to how continents could move apart.

Answer:

Explanation:
Answer:
The surface area to volume ratio decreases
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
This is why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to increase the surface area to volume ratio.
Describe a semipermeable membrane.
Answer:
A semipermeable membrane is a barrier that will only allow some molecules to pass through while blocking the passage of other molecules. A semipermeable barrier essentially acts as a filter. Different types of semipermeable membranes can block out different sized molecules. A semipermeable membrane can be made out of biological or synthetic material.
Explanation:
Answer:
A semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.
