Choose the answer that is not a fossil.
a petrified T-Rex is found in Montana
a 400-million-year-old fish preserved in rock
a cow skeleton in the desert
dinosaur footprints preserved in mud turned to rock
Answer:
The last one: dinosaur footprints preserved in mud turned to rock
Fossils have to be physical remains of an animal.
Hope this helps!
Answer:
(D) a cow skeleton in the desert
Explanation:
Because a petrified T-Rex is considered a fossil, a 400-million-year-old fish preserved in rock is also a fossil and a preserved footprint from a dinosaur is a fossil, the cow is the only one that is not a fossil because it does not remain or an impression of a prehistorical, organism because cows still exist today
Definition of a fossil: the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.

A mutation has occurred that results in a drastic reduction in mRNA transcription from very high levels to low levels. What region is likely responsible?
Answer:
Enhancer region
Explanation:
An enhancer is a cis-regulatory DNA region that binds to transcription factors in order to stimulate transcription. Enhancer regions are localized both upstream and downstream of the gene whose transcription regulates, at a variable distance ranging from 1 to 100 kilobases (kb) from the transcription start site. The first enhancer to be identified was found in an intron of the immunoglobulin gene. Conversely, a silencer element is a DNA region that binds to proteins known as repressors in order to suppress transcription.

The mRNA code determines which tRNA molecules are used. The purpose of this process is to synthesize protein. DNA contains the information used to make proteins. The presence of uracil (U) in codons makes difference between DNA and RNA. The correct options are A, D, C, C, and C respectively.
What is nucleic acid?Natural chemical substances called nucleic acids are the main information-transporting molecules in organisms.
They are particularly crucial in controlling protein synthesis. Deoxyribonucleic acid (DNA) and ribonucleic acid are the two primary types of nucleic acids (RNA).
That tRNA molecules are utilized is determined by the mRNA code. The creation of protein is the aim of this procedure.
The instructions needed to create proteins are found in DNA. Codons that contain uracil (U) distinguish between DNA and RNA as RNA possesses uracil in plane of thymine in DNA.
In the sequence given in the second image, the sequence of the mRNA will be C – U – A – G – G – A.
Thus, the correct options are A, D, C, C, and C respectively.

C: CLAY,ORGANIC LAYER, GRANITE
D: GRANITE, ROCK, SOIL
soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer

Which of the following is NOT a statement from the cell theory?
O All cells come from pre-existing cells.
•All cells require water for survival.
•All living things are composed of cells.
•Cells are the basic unit of structure and function of living things.
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
All cells require water for survival is not a statement from the cell theory.
What is cell theory?The cell theory is a fundamental principle in biology that states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. The theory was first proposed by German scientists Matthias Schleiden and Theodor Schwann in 1839, and later refined by Rudolf Virchow in 1855. The three main principles of the cell theory are:
All living organisms are composed of one or more cells.The cell is the basic unit of life and structure for all living organisms.All cells come from pre-existing cells through the process of cell division.The cell theory is considered one of the most important and enduring concepts in biology, and it forms the foundation for understanding the structure and function of cells and the organization of life on Earth.

Explanation:
Mutation 1 will cause translation to stop as there is presence of stop codon UAG, UAA, UGA.
What are the stop codons ?
In DNA or messenger RNA (mRNA), a stop codon is a sequence of three nucleotides (a trinucleotide) that tells the cell to stop making proteins. There are 64 distinct codons for trinucleotides. Three stop codons (UAA, UAG, and UGA) and 61 specific amino acids are included.Several codons, or triplet bases, make up the universal genetic code. To reduce coding errors, the standard code has developed over time. The genetic code is made up of 64 codons that are the result of the four bases in nucleic acids being permuted and combined.Since more than one codon can encode for a single amino acid, the genetic code is degenerate. Consequently, 61 of the 64 codons encode the 20 amino acids.The START and STOP codons, two punctuation marks in the genetic code, indicate the conclusion of protein synthesis in all organisms.Because it is the first codon in the transcribed mRNA to undergo translation, the codon AUG is referred to as the START codon. The amino acid methionine (Met) in eukaryotes and formyl methionine (f Met) in prokaryotes are both encoded by the most prevalent START codon, AUG. With the assistance of a few initiation factors, the t RNA recognizes the START codon AUG during protein synthesis and initiates mRNA translation.Amber (UAG), opal or umber (UGA), and ochre (UAA) are the three STOP codons. Charles Steinberg and Richard Epstein discovered Amber" or UAG and gave it the name "amber" after the German meaning of their friend Harris Bernstein's last name. In order to keep with the theme of "color names," the two remaining STOP codons were subsequently given the names "ochre" and "opal."To know more about codons check this:
