I think the correct answer from the choices listed above is option B. The geologic time scale originally ordered earth's rocks by relative age. The principle is that in a sequence of undeformed sedimentary rocks the oldest beds are at the bottom and the youngest ones are at the top.

How do wildfires help control plant disease? a. Wildfires are more likely to kill off plants that are likely to spread disease.
Bezzdna [24]

Answer:

d. All of the above

Explanation:

Wildfires are useful in controlling the ecosystem disturbed due to some diseases and insects.

With the help of wildfire, there will be a temporary loss in some region but it will lead to extraordinary growth.

Wildfire improves the soil quality by decomposing the organic material and renewing the soil nutrients.

There are chances of habitat loss but it will increase the production of food grazers.

Certain plants can be reproduced through wildfire due to cracking their seeds.

How do scientific theories compare to hypotheses? a Theories are the same as hypotheses. b Theories unify a broad range of obser
Maslowich

Answer:

b. Theories unify a broad range of observations and hypotheses.

Explanation:

In broad terms, theories are the set of principles that can or must be used to explain certain phenomena. It involves the involvement or inclusion of any set of principles to get to a conclusion.

Hypothesis, on the other hand, is just a term used for an assumption made. And this assumption may be made even before any observation has been done, a mere suggestion for how to proceed with things or an assumption about things.

Thus, scientific theories unify a broader range of observations that had been done, including any hypothesis. So, the <u>correct answer is option b</u>.

In order to make a protein the messenge on DNA must be converted to what?
Soloha48 [4]

Explanation:

-mRNA or messenger RNA

DNA wound into chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand.

Further Explanation:

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; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.  

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at 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, Guanine, 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.

Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.
