ultraviolet radiation = causes skin cancer and sunburn
electromagnetic wave = how Sun's energy travels to Earth
visible light = made of colors that the eye can see
Explanation:
Radiation is the transmission of energy in the form of waves or particles through space or a vacuum or through a material medium. The energy produced by the sun is transferred to other bodies such as the earth through radiation.
Infrared radiation is a form of electromagnetic radiation that is invisible to the human eyes but that takes the form of heat energy.
Ultraviolet radiation is an invisible form of electromagnetic radiation. It is produced by the sun and overexposure to it can cause sunburns, skin cancer and possibly blindness.
Electromagnetic waves are waves that are produced as a result of vibrations between an electric field and a magnetic field. The energy from the sun travels in the form of electromagnetic waves.
Visible light is a form of electromagnetic wave produced by the sun as well, that makes up the visible colors that we can see such as red, blue, green, etc.

I will give you 5 stars, points, and thanks if you answer this: Describe the positions of high and low pressure and the temperature of the land and water to explain how sea breezes form.
Answer:
A sea breeze or onshore breeze is any wind that blows from a large body of water toward or onto a landmass; it develops due to differences in air pressure created by the differing heat capacities of water and dry land. As such, sea breezes are more localised than prevailing winds. Because land absorbs solar radiation far more quickly than water, a sea breeze is a common occurrence along coasts after sunrise. By contrast, a land breeze or offshore breeze is the reverse effect: dry land also cools more quickly than water and, after sunset, a sea breeze dissipates and the wind instead flows from the land towards the sea. Sea breezes and land breezes are both important factors in coastal regions' prevailing winds.[1] The term offshore wind may refer to any wind over open water.
Wind farms are often situated near a coast to take advantage of the normal daily fluctuations of wind speed resulting from sea or land breezes. While many onshore wind farms and offshore wind farms do not rely on these winds, a nearshore wind farm is a type of offshore wind farm located on shallow coastal waters to take advantage of both sea and land breezes. (For practical reasons, other offshore wind farms are situated further out to sea and rely on prevailing winds rather than sea breezes.)

Why do some scientists believe that dinosaurs were warm blooded?
Answer:
Some paleontologists think that all dinosaurs were 'warm-blooded' in the same sense that modern birds and mammals are: that is, they had rapid metabolic rates. ... Some scientists think that very big dinosaurs could have had warm bodies because of their large body size, just as some sea turtles do today.
Explanation:
Hope this will help you
Some scientists believe that dinosaurs were warm-blooded because of evidence from their fossilized bones, growth rates, and the presence of features similar to modern warm-blooded animals.
The belief that dinosaurs were warm-blooded is based on several lines of evidence. First, studies of fossilized dinosaur bones have revealed features such as Haversian canals, which are characteristic of fast-growing, metabolically active animals. This suggests that dinosaurs had high metabolic rates similar to warm-blooded animals.
Second, researchers have analyzed the growth patterns in dinosaur bones and found that they exhibit characteristics of rapid growth, which is consistent with the growth rates observed in warm-blooded animals. Slow-growing reptiles, on the other hand, show different growth patterns.
Furthermore, some dinosaurs show evidence of insulation in the form of feathers or other types of integumentary structures. These structures would have provided insulation and helped regulate body temperature, similar to how feathers function in modern warm-blooded birds.
Additionally, the presence of large predators among the dinosaur species suggests an active and energetic lifestyle that is more characteristic of warm-blooded animals than cold-blooded reptiles.
While these pieces of evidence suggest that dinosaurs were warm-blooded, it is important to note that the debate among scientists is ongoing, and there is still no consensus. The study of dinosaur physiology is challenging due to the limited information available from fossil remains. Nonetheless, these lines of evidence contribute to the hypothesis that some dinosaurs may have exhibited warm-blooded characteristics.

What is the Law of Conservation of Mass? Why is it important in Earth’s recycling of water, oxygen, carbon, and nitrogen.
Answer:
Why is it important in Earth's recycling of water, oxygen, carbon, and nitrogen. ... In turn, the carbon dioxide in the atmosphere is absorbed by the plants that undergo photosynthesis. Therefore, the law of conservation of mass helps us understand how ecological balance is maintained through our ecosystems.
Explanation:
Hope this helps =)
Natural cycles follow the Law of conservation of mass. Elements go through different states in water, soil, air, and organisms to produce new matter needed for life.
What is the Law of Conservation of Mass?
The law of conservation mass, also known as the law of conservation of matter or the Lomonósov-Lavoisier law, is a chemical principle that establishes that mass is not created nor destroyed during chemical reactions. Instead, mass transforms.
According to this law, the amount of matter is always constant. What changes in the state of matter and how it is present in nature. Reactants are constantly consumed and transformed into products, and these products can also be transformed into the original reactants again
Through conservation of mass, it is possible to extract specific components of some raw material without discarding the rest. It also allows obtaining pure elements that would be impossible if the matter were destroyed.
Life on the Earth is possible because of recycling processes. And recycling is done following the concept of conservation of mass and energy.
Everything on the Earth is recycled and reused. This is done through the natural cycles that allow degradation of organic matter and transform it into new states that are used to produce new renewed matter.
Natural cycles are the natural processes in which the elements continuously circulate under varying forms in the air, water, soil, and organisms. As they circulate they are used to produce new matter.
Living and non-living things' production and free elements circulation depend on these cycles.

Determine whether the statement is true or false, and why. “If a point mutation occurs in a tumor gene it can become activated. This allows the rate of cell division to increase unregulated.”
A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
B. True
C. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This inhibits the rate of cell division decreasing it drastically.”
D. False, it should read “If a point mutation occurs in a Proto-oncogene gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Answer: A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Explanation: I already know this for a fact.
The statement “If a point mutation occurs in a tumor gene it can become activated. This allows the rate of cell division to increase unregulated" is false.
What is Point mutation?Point mutation may be defined as a method of genetic alteration that is caused by the substitution of a single nucleotide for another nucleotide in the DNA sequences. In this type of mutation, a single nucleotide base is altered through insertion or deletion from the sequence of DNA or RNA.
The above statement is false because if a point mutation occurs in a tumor suppressor gene it can become inactivated which terminates the expression of suppression of tumors.
And now the cell has the capability to grow unexceptionally with an irregular pattern. This allows the rate of cell division to increase unregulated and have a most potent threat of being infected with cancers.

All of the offspring produced in a test cross involving a brown rabbit and a white rabbit are brown. The result of this cross is best explained by A. Incomplete dominance B. Codominance C. Crossing over D. Dominance
Answer:
D
Explanation:
The result of the cross is best explained by dominance.
According to Mendel, when the alleles that make up a gene are different and one of the alleles is dominant over the other, the dominant allele would mask the effects of the recessive allele.
In the same vein, when the alternate version of the same trait is dominant, such trait would be expressed over the other version in heterozygous state.
Assuming that the genotype of the brown rabbit is BB and that of the white is bb. When the two rabbits are crossed:
BB x bb
Bb Bb Bb Bb
All the offspring would be heterozygous and brown in color because the brown allele is dominant over the white allele.
Hence, the correct option is D.
