Talc is the mineral which can be scratched with a fingernail and is therefore denoted as option A.
This is a mineral which consists of elements such as the following listed below and is often used as lubricants.
Fingernail is stronger which is why it can be scratched by it unlike the other minerals mentioned in the options.

Answer:
crust, mantle, and the core
Explanation:
Answer:
AUG (Methionine)
Explanation:
The process of protein synthesis occurs in two stages; transcription and translation. Transcription produces mRNA molecules from a DNA template. The mRNA's sequence is then read in a group of three nucleotides called CODON in the ribosome during the translation process.
Each Codon, of which there are possible 64, specifies an amino acid (building blocks of protein). Translation in the ribosome occurs when the ribosomal subunit binds to an mRNA molecule and a transfer RNA also binds using its anticodon (complementary to mRNA codon) to the AUG codon on the mRNA.
This AUG codon is regarded as the START CODON because it is the codon that initiates the commencement of translation. It encodes Methionine.
Answer:
Cellular respiration is a cellular process by which the organism in the presence of oxygen breakdown glucose and release energy that is stored in the form of ATP.
The by product of this process is carbon dioxide and water. This carbon dioxide is used by plants for the process of photosynthesis.
This is one of way by which carbon dioxide is provided to relay the carbon cycle.
a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
Thus, Deoxyribonucleic acid, or DNA, has a double helix-like structure. It is made up of two lengthy nucleotide strands that are spirally coiled around one another.
The complementary nitrogenous bases adenine (A) and thymine (T) and cytosine (C) and guanine (G) form hydrogen bonds that hold the two strands together.
This double helix structure is frequently compared to a spiral staircase or a twisted ladder.
Thus, a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.

The speed of sound is faster in the air than in the water.
The speed of sound does not change as it moves through the air or water.
The speed depends on how loud you yell.
The correct answer is: The speed of sound is faster in the water than in the air.
The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

A
