Answer:
1.The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.
2. As the combustible materials burn, some of the chemical energy is transformed into heat energy, and some is transformed into light energy. Light energy, also known as radiation or electromagnetic energy, is a type of kinetic energy that takes the form of visible light waves, such as the light from a match
3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
4. Answer: Refraction is the bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms, and rainbows. Explanation: Refraction.
5. The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
What statement best explains how the traits of an organism are determined by the DNA in each of their cells? Answer F DNA is translated into a strand of mRNA, which is used to control cellular functions G The information from DNA is used to determine the amino acid sequence of proteins H The hydrogen bonds of DNA are broken to provide the energy for protein synthesis. J The DNA double helix is unzipped, and each strand codes for a single protein.
Answer:
The information from DNA is used to determine the amino acid sequence of proteins
Explanation:
DNA is the genetic material of living organisms, which serves as a storage molecule for the genetic information needed to synthesize useful products (proteins). The information in the DNA, however, must undergo GENE EXPRESSION in order to be decoded.
The process of gene expression involves two major processes viz: transcription and translation. Transcription is the process by which DNA is used as a template to synthesize mRNA molecule while Translation is the process by which mRNA is used to synthesize amino acids, building blocks of proteins. Hence, the information from DNA is used to determine the amino acid sequence of proteins.

Explanation:
Let the allele for achondroplasia be represented by A.
Since the disease is lethal in AA condition, the two people would rather be Aa.
Aa x Aa
offspring AA Aa Aa aa
The AA offspring does not survive, hence, we are left with 3 children out of which 2 are affected heterozygotes and the remaining 1 is a true-breeding recessive and normal.
The expected ratio of affected to normal offspring is, therefore, 2 to 1.

Please help me finding an information: why there is life on Earth
Answer:
It seems possible that the origin of life on the Earth's surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 - 3.8 billion years ago.

Which of the following senses is mediated by mechanoreceptors?
A. Sight
B. Taste
C. Hearing
D. Smell
Hearing is the sense mediated by mechanoreceptors.
Mechanoreceptors are a type of receptors involved in the perception of:
Changes in the temperature.Movement.Vibrations or sounds.Pressure.One of the senses that is directly related to these receptors is hearing because this sense involves the perception of sounds through vibration or waves.
In this way, every time there is a sound the mechanoreceptors located in the ear perceive this sound and translate these waves into neural signs, which is necessary for the hearing process.
