Goiters may occur due to iodine insufficiency, but other causes are possible. Which of the following would NOT tend to result in increased size of the thyroid gland?
A. High levels of thyrotropin releasing hormone.
B. High levels of thyroid stimulating hormone.
C. High levels of thyroxin and triiodothyronine.
D. All of the above would tend to increase the size of the thyroid gland.
E. None of the above would tend to increase the size of the thyroid gland.
Answers
Answer:
Option A
Explanation:
Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is
a) over- or underproduction of thyroid hormones
b) Nodules in the glans
Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing the thyroid to swell
Thus, Option A is correct

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.
Answers
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.
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.
Answers
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.

Recall in class the example of incorporating heavy or light nitrogen labels into DNA to investigate how DNA is replicated. Imagine if, instead of labeling DNA, the experiment used heavy labeled RNA bases. What would be the outcome if you examined the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases?
Answers
Answer: You would not notice any difference or any labeled base, because RNA is not used to make DNA.
Explanation:
DNA is a molecule that contains the genetic information in all living things. The molecule consists of two strands that wind around each other to form a double helix structure where the strands are joined by hydrogen bonds. It is a nucleotide polymer where each nucleotide consists of a sugar called deoxyribose, a nitrogenous base (which can be adenine, thymine, cytosine or guanine) and a phosphate group (derived from phosphoric acid). What distinguishes one polynucleotide from another, is the nitrogenous base and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information.
Consider that DNA replication is semi-conservative, which means that each strand of the DNA double helix functions as a template for the synthesis of a new complementary strand. This process leads from one starting molecule to two "daughter" molecules, in which each new double helix contains one new and one old strand. Then, if nitrogen tags are incorporated into the DNA, they will register on the old strand of the new DNA molecule.
On the other hand, RNA (ribonucleic acid) is a molecule similar to DNA but has only one strand and consists of a sugar (ribose) and alternating phosphate groups. Attached to each sugar is one of the four bases adenine, uracil, cytosine or guanine. The process of RNA synthesis, called transcription, consists of making a complementary copy of a piece of DNA. During this process, an enzyme called ARN polymerase, adds nucleotides that are complementary to the DNA strand. Then, this new RNA strand has new nucleotides. Thereby, if you examine the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases, you would not notice any difference or any labeled base, because RNA is not used to make DNA.

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.

Explain your answer.''
Answers
Explanation:
What do you know about gravity?
ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
How could gravity affect the water cycle?
ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.
How many mL of stock solution of 2M NaCl do you need to prepare 100 mL of 0.150M NaCl?
Answers
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.
