An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown below, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. Brown bear Sun bear Spectacled bear Giant panda Lesser panda Raccoon Dog 100 0 So 60 40 20 Mulions of Years Ago 13 Which statement is best supported by the information in this dendrogram?
Answers
Answer: C
Explanation: Lesser pandas are more genetically similar to raccoons that they are to giant pandas.
The statement "Lesser pandas are more genetically similar to raccoons than they are to giant pandas" is not fully supported by the information in the dendrogram presented above.
What does the dendrogram suggest basically ?While it is true that the dendrogram suggests that the giant panda and lesser panda share a more recent common ancestor than either does with the other bears or the raccoon dog, it does not provide evidence to support the claim that the lesser panda is more genetically similar to raccoons than to giant pandas.
The dendrogram provides evidence for the evolutionary relationships among these organisms based on their DNA and RNA sequences. It suggests that these organisms have a common evolutionary history and can be grouped together based on their molecular data.
However, it does not provide information on the degree of genetic similarity between any two specific organisms or groups of organisms.
Therefore, while it is possible that the lesser panda may be more genetically similar to raccoons than to giant pandas, this claim cannot be fully supported by the information in the dendrogram alone.
Further analysis of genetic data and comparison of specific genetic sequences would be necessary to determine the degree of genetic similarity between these organisms.

In pea plants the trait for tall height is dominant over the trait for dwarf height. Which letter should be used to represent the genotype for plant height?
D
F
L
T
Answers
Answer:
The correct answer is - T.
Explanation:
Normally, the representation of the trait in the genotype of inheritance pattern is the first letter of the dominant character of the particular trait. In this case, the trait of the height of the pea plant is tall and dwarf.
Tall plants are dominant over the dwarf plant, therefore, the letter T would be used to represent the genotype for the height of pea plant, the small letter of the particular letter would be used to represent the alternate allele of the trait.

write the name of reproduction process that occurs in tapeworm?
Answers
Answer:
Hermaphroditic ReproductionExplanation:
See image for more
Depending on the species and circumstances, tapeworms can reproduce sexually or asexually. Proglottids, the several body segments that make up a tapeworm, are composed of both male and female reproductive cells.
What Hermaphroditic reproduction occurs in tapeworm?Some parasitic species, like the tapeworm, are both hermaphroditic and self-fertile, ensuring reproduction even if the parasite is the only member of its species present in the host.
Because tapeworms are hermaphrodites, each segment has both male and female reproductive organs. As the segment is pulled away from the neck, viable eggs will be released into the environment. When the segment is loaded with eggs, it separates from the adult tapeworm and is excreted in faeces.
Therefore, Hermaphroditic reproduction process that occurs in tapeworm.

organisms reduce the energy costs of reproduction?
A. The parents each take turns nurturing the offspring.
B. They reproduce asexually.
C. They have multiple offspring in one pregnancy.
D. They reduce their gestation period.
Answers
Answer:
B. They reproduce asexually.
Explanation:
Asexual reproduction often known as abiogenetic multiplication requires just one parent organism and results in hereditary identical progeny (similar to a new copy). Since there is no blending of genetic data required and organisms don't have to invest energy finding a mate, populaces can increment quickly because of asexual generation. Thus, with the guide of asexual generation, the energy needed in the process associated with multiplication and nurturing is diminished contrasted with sexual reproduction.

If the AG of a reaction was -31.45 kJoules, you would know that:
A. the products have more free energy than the reactants.
B. the reaction requires an energy input of 31.45 kJoules to proceed.
C. the reaction most likely leads to development of a more ordered system
D. the reaction is spontaneous
Answers
Answer:
The correct answer is - option D. the reaction is spontaneous. (considering it as delta G or ΔG)
Explanation:
If a chemical reaction has a negative ∆G it means the reactants have more free energy than the products due to the fact that they give off some of their free energy during the reaction.
Such reactions release free energy and therefore called exergonic reactions. These reactions are also known as spontaneous reactions as they do not require energy to take place.
Thus, the correct answer is - option D.
A garden pea plant possesses one allele coded for yellow seed colour and one a coded for green seed colour. Which statement is true?
Answers
A green pea plant possesses one allele coded for yellow seed color and one a coded for green seed color. The true statement is the individual is heterozygous for the seed-color allele.
What are alleles?At a given genomic location, an allele is one of two or more variants of DNA sequence (a mono base or a segment of bases).
For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent. If both alleles are identical, the person is similar for that allele.
Thus, the true statement is the individual is heterozygous for the seed-color allele.

He made this comparison because just as reading is a learned activity by the brain, so are the new flood of information that a child's brain must adapt to.
Explanation:
In describing the intricacies of the human brain, Dr. Jay Giedd talked about the brain's special ability to adapt to new behaviors as well as to multitask. Many of our ancestors lived and died without ever reading a book but humans alive today have adapted well to reading. So has the brain also adapted well to all the flood of information in our day.

Brad was provided with a piece of bread and egg yolk. He wants to know which component is present in the given food. Suggest him the scientific procedures to find the right component present in each food item.
Answers
Answer: Please see explanation column
Explanation:
Sample provided to Brad = a piece of bread and egg yolk
1. We know that Bread is a carbohydrate containing starch
To investigate the presence of starch/ Carbohydrate in Bread
Materials: Bunsen burner,test tubes, food product -Bread,iodine solution
Method
1. Place a sample of bread into the test tube.
2. Place a few drops of iodine solution on the bread
3. Take observations.
4. Wait a few more minutes and note any other changes.
Observations
On addition of iodine to the bread , if we notice a blue-black coloration, we will conclude that the right component found in bread is starch /carbohydrate
The above procedure can also be confirmed using
-Molisch’s reagent–which gives us a purple or violet color ring on addition to the bread
- Fehling’s reagent –which gives a Red precipitate to indicate the presence of in the bread
-Benedict’s reagent –which gives Red precipitate to indicate the presence of carbohydrates in the bread.
-Tollen’s reagent – which gives us Silver mirror to confirm the presence of carbohydrate in the bread.
2. We know that egg yolk contains protein,
To investigate the presence of Protein in egg yolk using biuret test
Materials: Bunsen burner,test tube, food product -egg yolk , Aqueous copper sulfate solution
Method
1. Place a sample of egg yolk into the test tube.
2. Place a few drops of Aqueous copper sulfate solution on the sample of egg yolk
3. Note observations.
4. Wait a while and note any other changes.
Observations
On addition of Aqueous copper sulfate to the egg yolk , if we notice a violet coloration,we will conclude that the right component found in egg yolk is protein
The above procedure can also be confirmed using
Xanthoproteic test – which on addition of Nitric acid to the egg yolk gives a Yellow coloration
Millions test – which on addition of Mercuric sulfate in the presence of sodium nitrite and sulfuric acid to the sample of egg yolk gives Brick red color solution confirms the presence of proteins.
Ninhydrin test – which on addition of Pyridine solution of ninhydrin to the sample of egg yolk gives Violet color solution confirms the presence of proteins.
