Use the information and model to answer the following question.
Echippus is an early ancestor to modern horses that lived 40 million years ago. The organism had a short neck, a short tail and feet with four toes. After ten million years, the tail and neck became longer and one of the toes disappeared as evidenced by the fossil of Mesohippus. Evolution of these organisms continued for 20 million years up to the present day causing the organisms to have longer necks and one solid hoof.
Answer:
D
Explanation:
The fossil record shows that the mammals gradually evolved so that their toes became one large hoof so this variation must have been more useful for survival than many toes. The correct option is 1.
What is fossil record?Paleontologists, archaeologists, and geologists use the fossil record to place important events and species in the correct geologic era.
It is based on the Law of Superposition, which states that the bottom layers in undisturbed rock sequences are older than the top layers.
The neck and toes of early horse ancestors evolved in such a way that the neck and tail became longer and one of the toes disappeared over time. The fossil record demonstrates this, as Echippus had a short neck, a short tail, and four-toed feet.
The fossil record shows that mammals gradually evolved their toes into one large hoof, implying that this variation was more useful for survival than many toes.
Thus, the correct option is 1.

A marble has a volume of 2 cm3 and its mass is 10 grams. What is the density of the marble?
Answer:
Density = 5
Explanation:
Formula: density = mass divide by volume
Mass = 10
Volume = 2
so 10 divide by 2 will give density
density = 5

What are the formulas for Newton's 1,2,3 laws of motion?
How did he come up with the idea of his book?
Newton's three laws of motion can be summarized by the following formulas:
Law of Inertia, Newton's 1st Law of motion:
F = 0, or F = ma if there is an acceleration.
This means that if an object is at rest, it will remain at rest unless acted upon by an external force. Similarly, if an object is in motion, it will continue to move in a straight line at a constant speed unless acted upon by an external force.
Newton's second law of motion:
F = ma
This formula states that the acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to its mass. In other words, the greater the force applied to an object, the greater its acceleration will be. Similarly, the greater the mass of an object, the smaller its acceleration will be for a given force.
Newton's third law of motion:
FAB = -FBA
This formula states that for every action, there is an equal and opposite reaction. In other words, when one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
Isaac Newton's most famous book, "Philosophiæ Naturalis Principia Mathematica" (often called "the Principia"), was based on his own research and discoveries in mathematics and physics. The idea for the book came from his desire to develop a comprehensive system for explaining the workings of the natural world based on mathematical principles. He began working on the book in the 1660s, and it was first published in 1687.

The balloon is positively charged and your hair is negatively charged so they attract. What would happen if you tried to put the balloons together?
Answer: The balloon is charged by rubbing it on your hair. When you put it near a neutral object (paper, Styrofoam or puffed rice cereal), the electrons in the object repel away from the balloon and the protons are attracted to the balloon. This movement of the electrons causes the neutral object to get a low positive charge.

Which material refracted the light rays the most: air, water, or glass?
The glass refracted the light the most, bending it to a
Which material refracted the light rays the least: air, water, or glass?
The air refracted the light the least because the light did not bend at all.
How does density affect refraction?
Density affects refraction because light waves, unlike sound waves, don’t need to interact with other particles to travel and they travel faster in the air and since light travels in a straight line, the denser the material gets the less it will be able travel in a straight line hence, it will refract more the denser the material gets.
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.
Since diamonds are very dense material, I predict that the light will refract because light travels in a straight line and does not need to interact with other materials to travel, so the light will refract in the dense material.
Explain where you observe reflection, refraction, and absorption of light in your everyday activities

2. Which material refracted the light rays the most: air, water, or glass
I have found that glass refracted the most.
3. Which material refracted the light rays the least: air, water, or glass?
I found that air refracted the least because there was no bend.
4. How does density affect refraction?
Density affects refractions because of light waves unlike sound waves. sound waves don’t need to interact with the other particles to travel faster in the air and since light always travels in a straight line the denser the material gets and the less it will travel in a straight line. Hence it would refract more the denser the material gets.
5. Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.
A diamond is a very dense material. So, I can predict that light would refract in the material because light travels in a straight line and does not need to interact with any objects or materials to travel so the light would refract in the dense material.
6. Explain where you observe reflection, refraction, and absorption of light in your everyday activities
In my everyday life I notice a reflection in the mirror or in a window. I also can observe a refraction when I drink a glass a water using a straw. I can also observe that while I’m cleaning the dishes how the water absorbed into the sponge.

Water bears are microscopic animals. When water bears are exposed to a vacuum of space, about 30% of them can survive.
A scientist is doing an experiment on water bears and vacuum exposure.
Which option is a prediction that relates the outcome of the scientist’s experiments with probability?
1. The scientist thinks water bears can survive vacuum exposure because they have little water in their bodies.
2. The scientist thinks that under some conditions, up to 40% of the water bears can survive.
3. The scientist thinks that there is a 15% chance that he will receive funding for more research.
4. The scientist thinks that other animals can also survive vacuum exposure.
Answer:
I would number 1
Explanation:
Tiny invertebrates called ‘water bears’ can survive in the vacuum of space, a European Space Agency experiment has shown. They are the first animals known to be able to survive the harsh combination of low pressure and intense radiation found in space.
Water bears, also known as tardigrades, are known for their virtual indestructibility on Earth. The creatures can survive intense pressures, huge doses of radiation, and years of being dried out.
This is some old research found about them hope u can find something from these two paragraphs.
The scientist thinks water bears can survive vacuum exposure because they have little water in their bodies. Hence, option (1) is a prediction that relates the outcome of the scientist’s experiments with probability.
What is water bear or Tardigrade?Tardigrades are a phylum of eight-legged segmented micro-animals, also known as water bears or moss piglets. Johann August Ephraim Goeze, a German biologist, initially identified them as Kleiner Wasserbär in 1773. ("little water bear"). They were given the Tardigrada moniker in 1777 by the Italian naturalist Lazzaro Spallanzani, which translates to "slow steppers."
They have been discovered in many different biospheres on Earth, including the Antarctic, deep water, tropical rainforests, and mountaintops. Individual species of tardigrades may endure extreme conditions that would swiftly kill most other known forms of life, including exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and malnutrition. Even in space, tardigrades have managed to survive.
