how does the speed of sound vary based on the density of the material the sound is traveling through? ​

Biology

Firdavs [7]3 years ago
3 0

Answer:

A substance that is more dense per volume has more mass per volume. ...

Explanation:

Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.

Mariulka [41]

Answer: Option D) cofactor that is an activator of the enzyme.

Explanation:

A cofactor is a non-organic component (usually a metal) of an enzyme or protein, that enhances its function. Good examples of Cofactors include iron in hemoglobin, zinc in carboxypeptidase.

Zinc at the active site of the enzyme, carboxypeptidase helps it in cleaving off aromatic amino acids.

<em>Explanation: </em>

<em>Complete question... </em>

<em>a) the same codons are assigned to the same amino acids in most living things. </em>

<em>b) the same codons are assigned to the same DNA sequences in most living things. </em>

<em>c) None of these are correct. </em>

<em>d) the same amino acids are assigned to the same DNA sequences in most living things. </em>

<em />

<em>The genetic code is ubiquitous- it is found </em><em>everywhere</em><em> in most living organisms. Thus </em><em>a) the same codons are assigned to the same amino acids in most living things. </em>

<em />

<em>S</em>equences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P... life on Earth is Carbon based nucleotides contain 5-carbon sugars, and  nitrogen; the bases may contain single to double bond rings

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Codons are three nucleotide bases, with each codon encoding an amino acid or signalling the beginning or end of protein synthesis.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Xelga [282]

<u>HEYA!!</u>

<u><em>Answer:</em></u>

1.Both the Assertion and the Reason is correct and the Reason is the correct explanation to the Assertion.

<em><u>Explanation:</u></em>

Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.

<u>HOPE IT MATCHES!!!</u>
