Explanation:
In Mendel’s day, many people thought that offspring inherited a blend of their parents’ traits. For example, they thought that an animal with white fur and an animal with black fur would produce offspring with grey fur. This is called the blending theory of inheritance. How did Mendel show that the blending theory was incorrect?

1. Space probes have not landed on Pluto yet. Describe three types of information you would collect if you were designing the probe.
2. Pick a planet (other than Earth) and describe 5 characteristics that you know about it. Be as specific as possible.
3. What are the various features of the moon and how did they form?
All answers must come with an explanation.
Answer:
Space probes are made to conduct science experiments. They do not have people on them. Space probes have helped scientists get information about our solar system. Most probes are not designed to return to Earth. Some have landed on other planets! Others have flown past the planets and taken pictures of them for scientists to see. There are even some space probes that go into orbit around other planets and study them for a long time. The information they gather is used to help us understand the weather and other changes which happen on planets other than the Earth. This information is important in helping to plan other space missions such as ones to Mars and to Saturn.

A gas at constant temperature is confined to a cylinder with a movable piston. The piston is slowly pushed into the cylinder, decreasing the volume of a gas. The pressure increases. What are the variables in this experiment? (What is changing?)
a. temperature and time
b. time and volume
c. volume and pressure
d. pressure and temperature
The variables in this experiment are pressure and volume. So, option c is correct.
What is Boyle's law ?Boyle's law states that, the pressure of an ideal gas of a given mass is inversely proportional to its volume at constant temperature.
Here,
The gas is confined to a cylinder with a movable piston, at constant temperature. So, the temperature does not changes. The piston of the cylinder is pushed into it such that the volume of the gas decreases.
According to Boyle's law, the pressure of the gas is inversely proportional to the volume of the gas.
So, as the volume of the gas decreases, the pressure will increase.
This is because, since the the volume of the gas in the cylinder is decreasing, the gas molecules will come closer such that the space for their movement is decreased. As a result, the gas molecules collide with each other and thus resulting in an increased pressure, keeping the temperature constant.
Hence,
The variables in this experiment are pressure and volume.

If the Force exerted by the intern is doubled and the distance is halved, does the done by the intern increase, decrease, or remain the same?
Answer:
If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same. Work done is the force applied to move a body through a distance.
Explanation:
If the Force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same.
What is work?A force must be applied in order for work to be completed, and there must also be motion or displacement in the force's direction.
The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item. Work has no direction and only magnitude. Work is a scalar quantity as a result.
Let, initially Force exerted by the intern is F and distance is d at any angle θ. Then initial work done = Fd cosθ.
Latter, Force exerted by the intern is doubled and the distance is halved at the same angle θ. Then final work done = F/2 · 2d ·cosθ = Fd cosθ.
Hence, Work done remains same.

How is the Moon different during a new moon phase than during a lunar eclipse?
Answer:
A solar eclipse happens at the new moon phase, when the moon passes between the sun and Earth. A lunar eclipse happens at the opposite moon phase – at full moon – when the Earth, sun and moon align in space, with Earth between the sun and moon. EarthSky's lunar calendar shows the moon phase for every day in 2021.
Explanation:
During a new moon, it is more or less between the Earth and the Sun, whereas a lunar eclipse ALWAYS occurs during a full moon.
The new moon is the astronomical phase that indicates the beginning of a new lunar cycle.During a new moon, the moon is found between the Earth and Sun (not exactly between), thereby the moon's surface is dark because the light side is facing away from Earth.Conversely, a lunar eclipse occurs when the moon passes through the shadow of the Earth, which only happens during a full moon.In conclusion, during a new moon, it is more or less between the Earth and the Sun, whereas a lunar eclipse ALWAYS occurs during a full moon.

a 0.15 kg baseball has a momentum of 0.78 kg*m/s just before it lands on the ground. What was the ball's speed just before landing?
The speed of the ball (i.e the velocity since it has a direction in a specified time) is 5.2 m/s before it landed.
From the given information,
the mass of the baseball = 0.15 kgthe momentum of the baseball = 0.78 kg m/sFor an object moving in a direction in a specified time, the momentum of the object is usually directly proportional to the mass and velocity.
∴
Momentum = mass × velocity
velocity = momentum/mass
velocity = 0.78 kgm/s ÷ 0.15 kg

What is the difference between serous and mucous membranes?Serous membranes usually line closed cavities within the body, for example, the pericardial cavity. These membranes secrete a serous or watery fluid.
On the other hand, mucous membranes are thicker, and the line surfaces of the body are exposed to the external environment, for example, the respiratory tract. These membranes secret mucus but sometimes they can secret liquids, an example is the conjunctiva.

Briefly explain Sir Isaac Newton’s prism experiment this text is your resource:
"In 1665, Isaac Newton was a young scientist studying at Cambridge University in England. He was very interested in learning all about light and colors. One bright sunny day, Newton darkened his room and made a hole in his window shutter, allowing just one beam of sunlight to enter the room. He then took a glass prism and placed it in the sunbeam. The result was a spectacular multicolored band of light just like a rainbow. The multicolored band of light is called a color spectrum."
Answer:
His investigations into optics commenced in 1666 at the end of an annus mirabilis when, at home in Wools Thorpe, Lincolnshire due to the bubonic plague which was raging in Cambridge, he investigated gravity, calculus and the laws of motion. He determined to ‘try therewith the celebrated Phenomena of Color’. It had been thought previously that colour was created by the mixing of light and darkness. Newton noted, however, that the blended print on the white page of a book appears grey, not coloured, when viewed from a distance. His experiments in bending light through prisms led, eventually, to the revolutionary discovery of the existence in white light of a mixture of distinct coloured rays, distinguishable when refracted in a prism. In his first experiment he projected the light via a round hole in his shutters.

explain how climbing a mountain is similar to hiking from the equator to one of the poles
Climbing a mountain is similar to hiking from the equator to one of the poles is same as in both cases acceleration due to gravity and weight of the object falls as the object goes far.
What is weight?The amount of a body's weight indicates how much gravity is pulling on it. Weight is calculated using the method w = mg. Since weight is a force, it has the same SI unit as a force, which is the Newton (N).
When an object climbs a mountain, altitude of the object increases - that's way - acceleration due to gravity and weight of the object decreases. Similarly, when an object hikes from the equator to one of the poles, acceleration due to gravity and weight of the object decreases. In this way, climbing a mountain is similar to hiking from the equator to one of the poles.
