Analyzing Erosion Scenarios In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario? Write a few sentences
Answer:
There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.

what type of igneous rocks are the Hawaiian islands
The Hawaiian Islands are nearly entirely made of basalt lava, the most abundant type of rock on the planet.
What is igneous rock and its type ?Hot, molten rock crystallizes and hardens to produce igneous rocks, which are named after the Latin word for fire. The melt begins deep inside the Earth around hot regions or active plate borders, then it rises toward the surface. Depending on where the molten rock hardens, igneous rocks are classified as either intrusive or extrusive.
Intrusive Igneous Rocks: When magma is imprisoned in the Earth's interior, intrusive, or plutonic, igneous rocks are created. The individual mineral grains have a very long time to develop because of the slow cooling, and as a result, they reach a comparatively enormous size. Rocks that are intrusive have a coarse-grained texture.
Thus, Hawaiian islands are made up of basalt ; the most common rock on the earth.

How does a stem cell become specialized into a heart cell?
Answer:
Explanation:
stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.
Daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either develop into fresh stem cells or into differentiated cells with a more specific role, such as bone, blood, brain, or heart muscle cells.
How are stem cells differentiated?According to research, cardiomyocytes made from pluripotent stem cells can develop into beating human heart muscle cells that both produce the required signals and restore muscle lost during a heart attack.
Stem cells have the ability to multiply and develop into a variety of relatively mature cells. When inserted into a blastocyst, embryonic stem cells have the ability to develop into any organ in the human body.
Therefore, theoretically, every organ in the body might be replaced using embryonic stem cells.

Alana summarized what happens when a ball sitting on top of a grassy hill rolls down the hill.
The motionless ball has potential energy. Once the ball starts to roll down the hill, new kinetic energy is made. As the ball rolls across the grass, it slows down. The kinetic energy of the ball is converted to other forms of energy.
Which best describes Alana’s error?
The motionless ball does not have energy because it is still.
Kinetic energy is not made; it is a result of energy transformation.
The ball cannot slow down unless someone touches it.
The energy is not converted; it disappears.
Answer:
It's actually B that guy is wrong on Edge.
Explanation:
Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.
What are the various types of energy?The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.
Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

What is some of the evidence used by Galileo to support Copernicus’s model and disprove Aristotle and Ptolemy’s?
Each planet spins in an epicycle.
Planets appear to move backward.
Jupiter has moons orbiting it.
The religious and cultural beliefs supported this model.
Claudius Ptolemaeus (85-165 AD) or Ptolemy believed Aristotle's theory that the Sun, Moon, and planets circled the Earth.
However, he improved it to account for the fact that planets sometimes appear to travel backward across the sky, called retrograde motion.
Galileo Galilei used various pieces of evidence to support Copernicus's heliocentric model and challenge the geocentric model proposed by Aristotle and Ptolemy. Some of the key evidence and observations that Galileo put forward include:
Observations of the phases of Venus: Galileo observed that Venus goes through phases just like the Moon.Observation of Jupiter's moons: Galileo discovered four moons orbiting Jupiter, now known as the Galilean moons (Io, Europa, Ganymede, and Callisto). Observation of Saturn: Galileo observed Saturn using his telescope and noticed the presence of what he called "ears" or "appendages" on each side of the planet.Lunar observations: Galileo's observations of the Moon revealed mountains, valleys, and craters, contradicting the notion of a perfect and unchanging celestial realm put forth by Aristotle and Ptolemy.Sunspot observations: Galileo observed sunspots, dark spots on the surface of the Sun.Thus, it's worth noting that while Galileo provided empirical evidence to support the heliocentric model, his ideas and evidence faced strong opposition from the religious and cultural beliefs of the time, as they contradicted the established dogma of a geocentric universe.

Think and discuss:Suppose you are a farmer trying to grow plants in a greenhouse. Why would it be important to know what the limiting factor is
Answer:
Because limiting factors affect plant growth
Explanation:
A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.
