Rhesus monkeys are more closely related to rabbits than they are to horses. (B) Horses and cows have identical amino acid sequences in their cytochrome c. (C) Humans are more closely related to rabbits than they are to rhesus monkeys. (D) Plants and animals have no similarities at all. (E) Mammals are more closely related to reptiles than they are to fish.
Complete question:
A scientist used the amino acid sequence of cytochrome c in different species to consider evolutionary relationships.
The data below summarizes the numbers of differences in the amino acid sequences of cytochrome C found in the selected species
Species compared Number of differences
Human-chimpanzees 0
Human-Rhesus monkeys 1
Human-Horses or Donkeys 7
Human-Cow, Pigs or sheeps 7
Human-Rabbits 7
Mammals-Birds and reptiles 10-15
Mammals-Fishes 18-20
Mammals-Plants 45-48
Interpretation of the data supports which of the following statements?
(A) Rhesus monkeys are more closely related to rabbits than they are to horses.
(B) Horses and cows have identical amino acid sequences in their cytochrome c.
(C) Humans are more closely related to rabbits than they are to rhesus monkeys.
(D) Plants and animals have no similarities at all.
(E) Mammals are more closely related to reptiles than they are to fish.
Answer:
(E) Mammals are more closely related to reptiles than they are to fish.
Explanation:
So, what you need to do here is to compare the number of differences found in each comparison. Remember that this information is only regarding cytochrome C. For instance, we can see that between humans and chimpanzees, the number of differences is 0. Their amino acid sequences do not differ at all. On the contrary, the comparison of mammals and plants threw a value of 45-48 differences, meaning that they are very different from each other, almost 50%.
So, this is how you need to interpret the values of the differences in this table. Now, let us go to the options,
(A) Rhesus monkeys are more closely related to rabbits than they are to horses. Rhesus monkey was not compared to any group other than humans, so we could not say that they are more related to one animal or the other.
(B) Horses and cows have identical amino acid sequences in their cytochrome. When comparing humans with horses and then humans with cows, the number of differences was the same -7-. But these results do not indicate which are the differences. Remember that we are comparing amino acid sequences, so probably the number of differences of each group with humans is the same, but the amino acid sequences between horses and cows are not.
(C) Humans are more closely related to rabbits than they are to rhesus monkeys. Humans and rhesus monkeys express only one difference in the amino acid sequence, while humans and rabbits exhibit seven differences. This result means that humans are more closely to rhesus monkeys related than they are to rabbits.
(D) Plants and animals have no similarities at all.
As we mentioned before, plants and mammals have a difference of almost 50% in their amino-acidic sequences. It does not mean that the other 50% is also different.
(E) Mammals are more closely related to reptiles than they are to fish.
The amino acid sequence of mammals and reptiles show 10-15 differences
The amino acid sequence of mammals and fish show 18-20 differences
So yes, mammals seem to be more related to reptiles than to fishes because the number of differences with reptiles is fewer.

Chemicals similar to ecdysone and juvenile hormone are widely used commercially to control insect pests
Answer:
Certain plants contain compounds similar to ecdysone which serve as a defense against insects. False
Juvenile hormone levels are high in insect larvae, but must decrease in order for metamorphosis to occur. True.
Chemicals similar to ecdysone and juvenile hormone are widely used commercially to control insect pests. True
Explanation:
The plants produce toxic chemicals such as terpenoids, alkaloids, anthocyanins, phenols, and quinones as a defense against insects. Juvenile hormone levels are high in insect larvae but its concentration decrease when the insect transform into adult stage and in order to occur metamorphosis. Ecdysone and juvenile hormone are widely used as insecticide because it prevents the insects to transform from larva to adult so if they can't mature they can't harm the plants or other things of our environment.

Imagine you are producing a short film depicting the molecules and biological processes involved in gene expression. For this, you need to first create a storyboard for your film. A storyboard is a sequence of drawings, along with some description or dialogue, that illustrates and represents the scenes of a story or movie. Create a storyboard for the process of gene expression/central dogma depicting the story of how the cell uses the information in DNA to synthesize a protein.
Answer:
By decoding information with the help of transfer RNA (tRNA).
Explanation:
The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.

How many mL of stock solution of 2M NaCl do you need to prepare 100 mL of 0.150M NaCl?
Answer:
7.5mL
Explanation:
Comsidering the definition of dilution, 7.5 mL of the stock solution of 2 M are required to prepare 100 mL of 0.150 M solution.
Dilution is a procedure by which the concentration of a solution is lowered. It is achieved by adding more solvent to the same amount of solute.
Then the amount of solute does not vary, but the volume of the solvent does: when more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume
In this case, you know:
Ci= 2 M Vi= ? Cf= 0.150 M Vf= 100 mLReplacing in the definition of dilution:
2 M×Vi= 0.150 M×100 mL
Solving:
[tex]Vi=\frac{0.150 M x 100 mL}{2 M}[/tex]
Vi= 7.5 mL
In summary, 7.5 mL of the stock solution of 2 M are required to prepare 100 mL of 0.150 M solution.

What are evolutionary relationships?
Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:
Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.
The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.
Therefore the correct option is B.

Discuss the role of carbon storage in organisms
It only has to be one paragraph :)
Answer:
Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.
