How does light travel?
Give facts about the topic
Make everything kid-friendly
Answers
Answer:
Normally, light travels in a straight path called a ray, however, when passing through clear materials, like water or glass, light bends or turns. As a result, the direction and speed of the traveling light wave will change and the light will appear to bend or change directions.

Where do the animals you read about get the energy storage molecules they need to do the activities required for reproduction?
Answers
The animals that you read about get the energy storage molecules they need for reproduction from the food they eat. Food provides the energy and nutrients required for various biological processes, including reproduction.
What is reproduction?Reproduction is the biological process by which organisms produce offspring, either sexually or asexually, to ensure the survival and continuation of their species. It is an essential characteristic of living organisms and is critical for the maintenance of genetic diversity within a population.
Sexual reproduction involves the fusion of gametes (reproductive cells) from two parents, which results in the formation of a new individual with a unique combination of genetic material. In most sexual reproduction processes, the male produces sperm, while the female produces eggs. The sperm and egg unite during fertilization, which creates a zygote that develops into a new organism.
Asexual reproduction, on the other hand, involves the production of offspring from a single parent without the fusion of gametes. The offspring produced through asexual reproduction are genetically identical to the parent, except for mutations that may occur during the process.
Reproduction is essential for the continuation of a species and is responsible for maintaining the genetic diversity within a population. It also plays a critical role in the evolution of species by allowing for the accumulation of genetic variation through sexual reproduction and mutation.
Here in the Question,
The three main macronutrients in food that provide energy for the body are carbohydrates, proteins, and fats.
These macronutrients are broken down during digestion into smaller molecules such as glucose, amino acids, and fatty acids, which can be used by the body to produce energy through cellular respiration.
The energy produced from food is stored in the form of adenosine triphosphate (ATP), a molecule that provides energy for various cellular processes, including reproduction. Animals obtain their energy storage molecules such as ATP through the process of cellular respiration, which occurs in the mitochondria of cells.
Therefore, animals get the energy storage molecules they need for reproduction from the food they eat, which provides the necessary nutrients and energy required for various biological processes.

ans 1 ; It also includes frozen rivers and lakes, which mainly occur in polar areas. The components of the cryosphere play an important role in the Earth's climate. Snow and ice reflect heat from the sun, helping to regulate our planet's temperature.
ans 2 ; Deep-sea trench, also called oceanic trench, any long, narrow, steep-sided depression in the ocean bottom in which occur the maximum oceanic depths, approximately 7,300 to more than 11,000 metres (24,000 to 36,000 feet). They typically form in locations where one tectonic plate subducts under another.
ans 3 ; The calm waters provide a safe area for small fish, shellfish, migrating birds and shore animals. The waters are rich in nutrients such as plankton and bacteria. Decomposing plant matter, called detritus, provides food for many species. ... This means the estuary must support a wide variety of food webs.
ans 4 ; Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

As radiation from the sun reaches the earth, the energy is-
A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere
Answers
Answer:C
Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.
B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere
C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.
D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation

all of the followings are examples of greenhouse gases except:
A ) Carbon Dioxide
B ) Methane
C ) oxygen
D ) Nitrous Oxide
Answers
Answer:
I think it's C
Explanation:
C which is oxygen all the rest are greenhouse gases, but I don't think oxygen itself is one
Oxygen is not an example of a green house gas.
A greenhouse gas is any gas that is capable of trapping infrared rays close to the earth surface thereby preventing its escape leading to a gradual rise in the temperature of the earth called global warming. The earth keeps getting hotter due to global warming
Global warming has led to the melting of polar ice caps and consequent flooding in some parts of the world.
Greenhouse gases are contributing to the gradual rise of the temperature of the earth as they prevent the escape of infrared rays.Human activities such as burning of fossil fuels for energy supply are exacerbating the menace of greenhouse gases in the atmosphere
Carbon Dioxide, Methane and Nitrous Oxide all contribute to global warming but oxygen gas does not.

Balanced forces is when is pretty much when no motion is happening
Amira hits a tennis ball with her racket. The tennis ball flies across the tennis court. She says that hitting the tennis ball is an example of balanced forces. Is she correct?
A.
Yes, because the forces acting on the ball are equal on all sides.
B.
Yes, because she hits the ball with more force in the forward direction.
C.
No, because she hits the ball with more force in the forward direction.
D.
No, because the forces acting on the ball are equal on all sides.
Answers
Answer:
the answer is C.
Explanation:
specifically, as a tennis player, Amira is completely wrong. Balanced forces are when an object has equal forces acting on it. When Amira hits the tennis ball, it bounces off and (maybe) over the net (if she aims it correctly). Hitting a tennis ball is an unbalanced force because you are hitting it in a different direction with enough force to make it change direction.
The force on the ball is not balanced, because she hits the ball with more force in the forward direction, so option C is correct.
What is force?In the body, force is the result of either a push or a pull. The three main categories of forces are friction, nuclear, and gravitational. For instance, when a hand strikes a wall, the hand puts force on the wall and the wall also exerts a force on the hand. Newton was given a variety of laws to help him understand force.
Newton is a physics unit of force that is a part of the International System (SI). A newton is the amount of force needed to move a body weighing one kilogram one meter per second.
Specifically, Amira is totally incorrect in terms of tennis. The presence of equal forces operating on an object is known as balanced forces. The tennis ball bounces off and (maybe) crosses the net as Amira strikes it (if she aims it correctly). When you strike a tennis ball, you are applying an imbalanced force since you are striking it in a different direction and hard enough to cause it to alter course.
Therefore, the force on the ball is not balanced, because she hits the ball with more force in the forward direction.
