Compare how natural selection selects for organisms with beneficial traits over those with less beneficial traits for an environment.
Natural selection is the process by which animals adjust to their environments.The environment affects natural selection. Natural selection does not prefer characteristics that are better in some fundamental way.
Natural selection is a process that favors heritable characteristics that boost an organism's chances of survival and enable additional reproduction.
What decides which features are adaptive during the course of natural selection?
In evolutionary biology, we decide which qualities in an organism are adaptive (caused by natural selection) and which are non-adaptive or spandrels by examining whether or not that particular trait was something that arose for its current purpose would be an adaptation.

How does the double-helical structure of DNA explain how the molecules can be copied or replicated?
A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
B. Each strand receives the information from the DNA polymerase attached to the replication fork.
C. The nitrogenous bases on one strand are copied to the other strand.
D. The nitrogenous bases line up on each strand and are attached to each other.
Answer:
A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two antiparallel polynucleotide chains. This double helix serves as a template for its own duplication. DNA templating refers to the process by which a portion of the DNA molecule in a single strand is used as a template to be copied by complementarity base pairing. According to base-pairing rules, Adenine (A) always pairs with Thymine, while Guanine (G) always pairs with Cytosine (C). These nucleotide bases are each linked with their complementary base by hydrogen bonding. When base pairs separate, the hydrogen bond acceptor and donor groups of each strand allow the addition of nucleotides and synthesis of new DNA strands, a process catalyzed by specialized enzymes (DNA polymerases).

During his voyage on the HMS Beagle, Darwin observed the
beaks and behavior of finches. These finches were similar
in some ways to the single finch species that existed on
the mainland of South America. On the Galápagos Islands,
however, there were 13 different species, each with
different beaks and different diets. Later, Darwin
hypothesized that natural selection could explain the
differences in the finch species. Many years later,
Rosemary and Peter Grant of Princeton University began to
test Darwin's hypothesis.
Scientists have recently developed a hypothesis based on
evolutionary concepts and the Grants' work. First, finches
from South America arrived on one of the islands. Then,
the finches that arrived on the island had to survive in a
new environment. The plants on the island were different
from the plants on the mainland. As a result, the
population on the island evolved differently from the
population on the mainland.
Later, a few finches from the island may have flown to
another island and begun the speciation process again.
This process may have been repeated many times. Now
there are 13 distinct species.

Frameshift mutation are the result of what occurrence?
Explanation:
A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier in the sequence the deletion or insertion occurs, the more altered the protein. A frameshift mutation is not the same as a single-nucleotide polymorphism in which a nucleotide is replaced, rather than inserted or deleted. A frameshift mutation will in general cause the reading of the codons after the mutation to code for different amino acids. The frameshift mutation will also alter the first stop codon ("UAA", "UGA" or "UAG") encountered in the sequence. The polypeptide being created could be abnormally short or abnormally long, and will most likely not be functional.
We discovered that both carbon dioxide and methane have been increasing in earths atmosphere. What ideas do you have about why this might be happening? What could be causing earths atmosphere to change?
Answer:
Due to human activities.
Explanation:
This change in the concentration of carbondioxide and methane gas is happening due to human activities because human used fossil fuels which can be burn in the engines of vehicles that releases carbondioxide gas in the atmosphere. Humans are responsible for the change of atmosphere which leads to change in the climate all over the world. Methane gas is also released by human activities such as using methane for cooking food.

Answer:
B) Image 1 -> Image 3 -> Image 4 -> Image 2
Explanation:
The pictures of the ecosystems are needed to be put into the simplest -> complex order.
Image 1 could be the simplest as it only has one organism.
Image 3 would be the next simplest as it has only a group of the same organism.
Image 4 would come next as it has aqua life and surroundings but the same fishes!
Image 2 would be the most complex, as it has various biodiversity and surroundings!
The order would go as Image 1 -> Image 3 -> Image 4 -> Image 2.

You go on an expedition into the Amazon Rainforest to look for new species before they are destroyed by logging. You find one organism you have never seen before. You run a few tests to determine what kind of organism it is. You determine that it is multicellular and that it first digests, then absorbs nutrients from the environment around it. What classification fits it best?
A. Plantae
B. Animalia
C. Fungi
D. Protista
Multicellular is a cellular classification where the organism is made of more than one cell. The multicellular organism that absorbs nutrients best fits in the kingdom of Fungi. Thus, option C is correct.
What is Kingdom Fungi?
Fungi is one of the five kingdoms that are characterized by eukaryotic organisms with multicellular structures. They contain microorganisms that are heterotrophs and cannot make their own food. They absorb the nutrients from decaying organic materials.
The fungal mycelia and filaments called hyphae allow fungi like mushrooms and molds to absorb nutrients and minerals from the surrounding. They digest the nutrients with the help of enzymes.
Therefore, option C. the Fungi first digest then absorb nutrients from the environment.

What are the four ways that RNA differs from DNA?
Answer:
RNA is single standard while DNA is double standard
RNA contains the sugar ribose, while DNA contains deoxyribose.
RNA contains uracil, while DNA contains thymine.
RNA can leave the nucleus, while DNA cannot.
Explanation:
RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
What is the difference between RNA and DNA?DNA stands for deoxyribonucleic acid which is defined as a double-stranded molecule consisting of a long chain of nucleotides whereas RNA stands for ribonucleic acid which is defined as a single-stranded molecule consisting of a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating but RNA does not replicate on its own.
The base pairing is of DNA is as follows: GC (Guanine pairs with Cytosine) A-T (Adenine pairs with Thymine) while the base pairing of RNA is as follows: GC (Guanine pairs with Cytosine) A-U (Adenine pairs with Uracil). RNA has the sugar ribose while DNA has the sugar deoxyribose. DNA is located in the nucleus of a cell and in the mitochondria while the RNA is found in the cytoplasm, nucleus and in the ribosome.
Thus, RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
