Answer: Choice D
Explanation: Natural selection explains how the strong survive due to mutations to suit the environment.
The statement that supports the theory of evolution by natural selection is D. Characteristics of populations can change over time in response to environmental changes.
What is theory of evolution?The theory of evolution by natural selection, first proposed by Charles Darwin, suggests that populations of organisms can change over time through the process of natural selection.
This occurs when individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over many generations, these small changes can accumulate and result in significant changes in the characteristics of a population.

The sedimentary rock layers are being weathered and eroded at different rates because the rock layers:
Explanation:
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from water solution.
The purpose of DNA replication is to * make changes in base pairs in order for an organism to evolve make an exact copy of a DNA strand for bacterial reproduction to repeat patterns of DNA in order to expand the bacterial genome to transribe information to RNA in order to synthesize proteins
Answer:
make an exact copy of a DNA strand for bacterial reproduction
Explanation:
The purpose of DNA replication would be to make an exact copy of a DNA strand for bacterial reproduction.
DNA replication is a process during which an extra copy of an organism's DNA is made following a series of steps. The replication usually precedes reproduction or the formation of daughter cells. Each daughter cells resulting from reproduction must have a complete genome that mirrors that of the parent or otherwise depending on the type of reproduction.
Without reproduction, DNA replication would not have been necessary.

Fill in the boxes in the template to identify the nucleotide sequence from 3' to 5' of the tRNA anticodon that will recognize codon 5 and the tRNA anticodon
Complete question:
(C) Fill in the boxes in the template to identify the nucleotide sequence, from 3' to 5´ of the tRNA anticodon that will recognize codon 5 and the tRNA anticodon that will recognize codon 510 of the mRNA template and to identify the amino acids that will be added at these two positions.
In the attached files you will find the image
Answer:
Codon Anticodon Amino Acid
5 CGG → GCC → Arginine, Arg
510 UAG → AUC → Stop
Explanation:
Some theory that you need to know to answer the question:
Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.
tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new peptidic link joins, placing together the new amino acid to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.
Now, to fill in the boxes, you need to pay attention to two things:
Anticodon: In this box, you need to place the sequence of bases that pairs with the mRNA codon. Amino Acid: In this box, you need to place the amino acid that is codified by the mRNA codon.For instance, let us say that the codon of mRNA is CUC.
The anticodon for this sequence is GAG (because guanine joins cytosine and adenine joins uracyl).
The amino acid placed on the 3´extreme of the tRNA molecule will be the one that is codified by the codon, NOT the anticodon. So, as the codon is CUC, the amino acid will be Leucine, Leu. Do not use the anticodon GAG to fill these boxes. Remember that tRNA is translating information carried by the mRNA, so we need to use this information to grow the protein.
So, in the problem, there are two codons: 5 and 510
Codon Anticodon Amino Acid
5 CGG → GCC → Arginine, Arg
510 UAG → AUC → Stop

Compare the DNA Sequence and circle any single base that is different in the cow and human sequences. How many bases are different?
Complete question:
Below are two partial sequences of DNA bases (shown for only one strand of DNA) Sequence 1 is from a human and sequence 2 is from a cow. In both humans and cows, this sequence is part of a set of instructions for controlling a bodily function. In this case, the sequence contains the gene to make the protein insulin. Insulin is necessary for the uptake of sugar from the blood. Without insulin, a person cannot use digest sugars the same way others can, and they have a disease called diabetes.
1 Using the DNA sequence, make a complimentary RNA strand from both the human and the cow. Write the RNA directly below the DNA strand (remember to substitute U's for T's in RNA)
2. Use the codon table in your book to determine what amino acids are assembled to make the insulin protein in both the cow and the human.
Human DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA
Cow DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC

1. Compare the DNA Sequence and circle any single base that is different in the cow and human sequences. How many bases are different? _____
2. Examine the amino acids produced. Highlight in yellow any amino acids that are different in the two sequences. How many are there? ______
3. Could two humans (or two cows) have some differences in their DNA sequences for insulin, yet still make the exact same insulin proteins? Explain.

Describe what might happen in the water cycle if
the amount of solar energy entering the Earth
system decreased.
When the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurThe water cycle can be described as a biogeochemical cycle that depicts how water is being circulated and recycled within, above, and on the earth's surface.
A typical diagram showing a water cycle is attached below.
From the water cycle diagram, we can observe that a vital aspect of the water cycle involves the sun which supplies solar energy that heats up earth.
The solar energy entering earth makes it possible for evaporation of water as vapor which form clouds that leads to rainfall.
The solar energy is also important in melting of ice, thereby converting it to water to goes into oceans for evaporation.
The implication of having an earth system where the amount of solar energy that enters it is reduced is that:
evaporation of water will reduced, clouds will not be able to form, and we won't have enough rainfall, andice would be predominant as low solar energy that is required to melt the ice is reduced.In conclusion, when the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
