Sometimes people refer to Mars as the Red Planet. Because of the rusty iron in the earth, it is red. Mars features weather, polar ice caps, canyons, volcanoes, and seasons just like Earth. Its atmosphere, which is composed of carbon dioxide, nitrogen, and argon, is extremely thin. These define Mars' characteristics.
These are some of the characteristics of the moon, which is the only natural satellite of Earth and the nearest huge celestial body. It is a spherical rocky body that revolves around Earth in a somewhat eccentric orbit at a mean distance of around 384,000 km (238,600 miles), perhaps with a tiny metallic core. It has a 1,738 km (1,080 miles) equatorial radius.
What is planet ?A celestial body inside the Solar System that meets the following criteria is referred to as a "planet": (a) it must be in orbit around the Sun; (b) it must have enough mass to overcome rigid body forces and take on a hydrostatic equilibrium form that is almost circular; and (c) it must have cleared the area in and around its orbit.

Sickle cell anemia is a recessive trait (aa) which causes a red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen to the body. Individuals with the genotype AA have normal red blood cells. Those individuals who are heterozygous for the trait usually have no symptoms of sickle cell disease, but carry the sickle cell trait and can pass it on to their offspring. However, those individuals who carry the sickle cell trait have some protective advantage against malaria, making this a common genotype in malaria prone areas. The graph illustrates the frequencies of two genotypes, AA and Aa, over many generations. Select ALL the conclusions you can draw from the graph provided.
A) There appears to be random mating between genotypes.
B) There is no selective advantage for one genotype over another.
C) This graph probably represents a population in a malaria-prone area.
D) The population reached equilibrium for these traits at about generation 35.
E) Sickle cell disease has died out of this population and will most likely not return.
Answers
Answer:A is your answer 2020 edg
Explanation:
The conclusion which can be drawn from the graph is that there appears to be random mating between genotypes.
What is a Graph?This is defined as the pictorial representation of data in an organized manner.
The graph shows that there is random mating between the genotypes due to the non-uniformity observed thereby making option C the most appropriate choice.

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².
What is acceleration?The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.
a = v²/r
a = (10m/s)² / 50m
a = 2 m/s²

What type of device is a coal-fired power plant?
A. A heat pump that uses heat to do work
B. A heat pump that uses work to move heat
C. A heat engine that uses work to move heat
D. A heat engine that uses heat to do work
Answers
A coal-fired power plant is a type of heat engine that uses heat to do work. So, the correct option is D.
What is meant by a power plant ?A power plant or power station is defined as a facility designed for producing electrical energy from various other forms of energy.
Here,
A coal-fired power plant is a type of power plant, which is used for the production of electricity by using fuels such as coal, oil, etc.
The coal-fired power plants are the most common type of power station. In these power plants, the main burning materials used are the fossil fuels. The coal is pulverized and then burned into a coal-fired boiler. Then, the boiler water is converted into steam using a heat engine. As a result, this steam is used for the spinning of turbines.
Hence,
A coal-fired power plant is a type of heat engine that uses heat to do work.

What does it mean that a material transmits waves?
Waves will stop and transfer energy when they hit the material.
Waves will pass through the material.
Waves will bend and change their direction slightly when they hit the material.
Waves will bounce off the surface of the material.
Answers
It means that a material transmits waves when the waves bend and change their direction slightly when they hit the material, which is the third option as there are different types of waves, such as X-rays and gamma rays, and they have different properties.
What is the significance of the waves?Waves are significant because electromagnetic waves are used in many areas of physics and technology, and waves like microwaves, infrared, and visible light are used in many technologies such as radio, communications, spectroscopy, etc., the waves are also useful in the field of quantum computing and in the medical field, etc.
Hence, it means that a material transmits waves when the waves bend and change their direction slightly when they hit the material, which is the third option as there are different types of waves, such as X-rays and gamma rays, and they have different properties.
