Answer:
In the late eighteenth century, when Hutton was carefully examining the rocks, it was generally believed that Earth had come into creation only around six thousand years earlier (on October 22, 4004 B.C.
James Hutton was a Scottish naturalist and geologist who discovered the age of the earth. The earth was believed to be 6000 years old by the Scottish people.
Who was James Hutton?
James Hutton is the father of modern geology and was involved in the discovery of the earth's age and the soil formation from the parent rocks. He made his contribution to discovering the age of Earth based on his observation rather than on assumptions.
Before he discovered the earth age, it was believed by the Scottish people that the planet was six thousand years old. He discovered the process of soil formation by weathering the parent and bog rocks that accumulated as sediments over years and allowed the discovery of the planet's age.
Therefore, it is believed that the earth was 6000 years old.

Which of the molecules above is a tRNA molecule?
none of the above.
A
Ծ Ծ Ծ Ծ
C
B
Answer:
B
Explanation:
Transfer RNA (tRNA) is an RNA molecule involved in the process of translation by which cells synthesize proteins. These molecules (tRNAs) have 76-90 nucleotides in length which form characteristic stem-loop structures, and they are considered adaptor molecules because tRNAs serve as the physical link between the messenger RNA (mRNA) and specific amino acid residues of the growing polypeptide chain. A tRNA is composed of a trinucleotide region (i.e., the anticodon region) that binds to the codon in the mRNA, and a region that attaches to a specific amino acid in order to transfer it to the ribosome, where protein synthesis takes place.

A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer). C)Exons 2 and 3 must contain a number of nucleotides that when divided by 3, leaves the same remainder (that is, 0, 1, or 2). D)Exons 2 and 3 must have different numbers of nucleotides. Multiple Choice
Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
When observing a plant cell under a microscope, what parts do you think would be big enough to see?
Answer:
Explanation:
There are a few key structural differences between plant cells and animal cells.
Below are a few of the main ones:
Plant cells are generally larger than animal cells.
Only animal cells have lysosomes (however, recent, and controversial, research suggests that some plant cells may have lysosomes), and only plant cells have chloroplasts.
While plants cells have a rigid cell wall, animal cells have a thin and flexible plasma membrane.
Plants cells have a large central vacuole and animal cells have many small vacuoles
When observing a plant cell under a microscope, one can see large interlocking rectangular blocks. Around each cell, the cell wall is clearly visible. When stained, the cell wall is somewhat thick and visible. The cytoplasm is also lightly stained, with a darkly stained nucleus at the cell's periphery.
What is a plant cell?A plant cell is a eukaryotic cell with something like a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells.
At the time of observing a plant cell under a microscope, person can see large rectangular blocks as well as cell wall is clearly visible.
When stained, the cell wall is thick and visible. The cytoplasm will also be lightly stained, with stained nucleus at the cell's periphery.
Thus, these structures can be visible under a microscope.

Answer:
AGU
Explanation:
AGU and AGC are the two codons that code for the amino acid, Serine. These codons are made of three nucleotides, thus they have a triplet nature. AGU that code for serine is made of Adenine, Guanine and Uracil joined together, carried on the messenger RNA to be added to the growing polypeptide chain
Determine which of the following statements is true about energy in ecosystems. A. Producers are able to convert 40% of the sun’s energy into chemical energy. B. 30% of the sun’s energy cannot be absorbed by producers because it is in the wrong wavelength of light. C. Producers only absorb 40% of the sun’s energy, most of which is lost during photosynthesis. D. Producers absorb 5% of the sun’s energy, and reflect 5% of the sun’s energy.
Answer:
A. Producers are able to convert 40% of the sun’s energy into chemical energy.
Explanation:
Energy in an ecosystem must be transferred in the ecosystem. The primary source of energy in an ecosystem is the sun. The terrestrial ecosystem mostly consists of plants and marine ecosystems. As energy flow in an ecosystem is unidirectional. It passed from the organism from one tropic level to another. Only 10% of the energy is available to them.Answer:

What process occurs during transcription? (2 points)
Synthesis of proteins that are coded for by mRNA
Copying of DNA to form an mRNA strand
Replication of DNA to produce a complementary DNA strand
mRNA folding up by forming complementary bonds with itself
Answer:
Copying of DNA to form an mRNA strand
Explanation:
In transcription, DNA is copied to form an mRNA strand with complementary bases.
The DNA strand being copied during the process is called the template strand, and the mRNA that is made will be created from that strand.
This is the first step of protein synthesis.
This strand of mRNA is further used during translation, where it is used to code for amino acids to make proteins.
So, the correct answer is Copying of DNA to form an mRNA strand
Answer: The correct answer is Copying of DNA to form an mRNA strand

Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules? Justified.
Answer:
Yes.
Explanation:
Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules because plants have various signaling molecules that plays a great role in their growth and development. Ethylene, auxin, cytokinins, gibberellins, and abscisic acid are the growth regulators that controls the growth of plants in different conditions i.e. in resistance. These signals leads the plant to take measures in difficult situations experience by the plants so in this way the plant is resistance to the harsh environmental condition.

In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. glucose in the blood fat in tissue calcium phosphate in bone glycogen in muscle cells protein in muscle cells
Answer:
fat in tissue
Explanation:
Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.
However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.
