Answer:
Explanation: "The relative ages of the rocks in the geological column are determined by the remains of the organisms that they contain. " The Geological Column in turn is used to establish and support the Darwinian model of the theory of organic evolution. That is descent with modification.
Humans affect Earth in many ways. The use of fossil fuels, the clear-cutting of forests, and controlled burns can affect the carbon cycle. Which process can help counteract these human interactions? photosynthesis respiration decomposition transpiration
Answer:
Photosynthesis
Explanation:
Photosynthesis takes in CO2 from the atmosphere and utilizes it to form sugars/oxygen.
The equation: 6CO2+6H2O -> C6H12O6 + O2
Respiration will do the opposite and actually release CO2 into the atmosphere
Decomposition will also release CO2 as a byproduct
Transpiration I don't believe has anything to do with removing or putting CO2 into the atmosphere. It's about water movement!
Answer:
The answer is A) Photosynthesis!

How does the heliocentric model of planetary motion explain a star's path across the night sky?
The sky is fixed and rotates around Earth.
Earth moves along its orbit daily to follow the stars.
The rotation of Earth makes objects in the sky appear to move.
Each star creates a different amount of light, imitating movement.
Answer:
The Rotation of earth makes objects in the sky appear to move
The heliocentric model of planetary motion explains a star's path across the night sky by The rotation of the earth makes objects in the sky appear to move; this is in Option C, as this is one of the best concepts on the planetarium models.
What is the significance of the planetary model?The planetary model is very significant, as the heliocentric model, proposed by Nicolaus Copernicus, explains that the sun is at the center of the solar system and shows that the planets, including Earth, revolve around the sun. This heliocentric model provided a more accurate explanation of the movements of the planets and paved the way for future research.
Hence, the heliocentric model of planetary motion explains a star's path across the night sky by The rotation of the earth makes objects in the sky appear to move; this is in Option C, as this is one of the best concepts on the planetarium models.

Data that indicate that the genetic code changes frequently.
Data that are inconclusive about the nature of.
the genetic code.
Data that indicate that some organisms use one or more alternate codes.
Data that indicate that the genetic code is the same in all organisms tested so far.
Answer:
hi here is your answer....
Explanation:
Data that indicate that the genetic code is the same in all organisms tested so far.
becuase,
The genetic code is nearly universal, and the arrangement of the codons in the standard codon table is highly non-random. The three main concepts on the origin and evolution of the code are the stereochemical theory, according to which codon assignments are dictated by physico-chemical affinity between amino acids and the cognate codons (anticodons); the coevolution theory, which posits that the code structure coevolved with amino acid biosynthesis pathways; and the error minimization theory under which selection to minimize the adverse effect of point mutations and translation errors was the principal factor of the code’s evolution.

Explanation:
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

Answer:
100% correct if you use the answers below :)
Explanation:
1. AGC TTT CG
2. CCA TAA CT
3. deletion
4. Chromosomes contain DNA
5. epigenetic change
A frameshift mutation involves the insertion or deletion of nucleotides in a DNA sequence, which modifies its open reading frame. A deletion is a mutation that involves the elimination of one nucleotide in DNA sequence.
With regard to the questions above described:
1. The sequence AGC TTT CG suffered a deletion of the Adenine (A) base at the second codon (i.e., AGC TTA TCG).2. The sequence CCA TAG CT exhibits a deletion of the Cytosine (C) base at the first codon (i.e., CCC ATA GCT).3. Cystic fibrosis is a recessive inherited disorder caused by a three-nucleotide (codon) deletion in the CF transmembrane conductance regulator (CFTR) gene. This deletion is associated with the loss of phenylalanine (Phe) amino acid in the exon 10 of the CFTR gene.4. The statement 'chromosomes contain DNA' is TRUE. Chromosomes are thread-like structures that contain part or all of the genetic material (DNA) of an organism.5. Epigenetic changes are modifications that affect an organism’s phenotype while leaving its DNA sequence. Epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation).In conclusion, frameshift mutations involve the modification of the Open Reading Frame. Deletion involves the elimination of a nucleotide in DNA. Chromosomes are thread-like structures that contain genetic material. Epigenetic modifications don't modify the genetic (nucleotide) sequence.
