The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?
a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.
Answers
Answer:
The correct answer would be - d. With the end of genetic isolation gene flow took place
Explanation:
It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.
Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.
Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.
What is the main function of cellulose?A. Component of cell wallsB. Water transferC. Energy storageD. Produces triglycerides
Answers
Cellulose is a polysaccharide of β-glucose which is mainly used by organisms such as plants to conform its cellular walls, to maintain their form and structure. This molecule, which is composed of carbon, hydrogen, and oxygen atoms, can also consist of too many monomers, from a few to almost thousands of them, and can give that rigidity to the cell because of the strength of their chemical links. Having this clear, we can say that the correct answer is the first one: A. Component of cell walls.

Answers
The density of cork can vary depending on factors such as its moisture content and the specific type of cork, but a typical range for the density of cork is around 0.24 to 0.32 g/cm3.
What is Density?
Density is a physical property of matter that describes how much mass is contained in a given volume of a substance.
Density = Mass / Volume
The standard unit of density is kilograms per cubic meter (kg/m3) in the International System of Units (SI), but it can also be expressed in grams per cubic centimeter (g/cm3) or other units.
However, based on the information you have provided, cork is a type of wood that floats on water, which means its density is less than that of water. The density of water is 1.00 g/cm3, so the density of cork must be less than 1.00 g/cm3 in order for it to float. In general, the density of cork can vary depending on factors such as its moisture content and the specific type of cork, but a typical range for the density of cork is around 0.24 to 0.32 g/cm3.

In many popular fictional movies and books, future projections of the earth (and other fictional planets) show a world devoid of plants, with civilization bustling with activity throughout a worldwide city of skyscrapers hundreds of stories high.
Based on your reading about photosynthesis and cellular (aerobic) respiration, is this future world possible? Explain why it is or is not possible in terms of energy flow in the biosphere.
Answers
Photosynthesis converts sunlight into organic compounds necessary for plant growth and cellular respiration releases energy from organic compounds to power biological processes. Without plants, there would be no source of organic compounds, and without cellular respiration, there would be no energy available for biological processes.
Therefore, a world without plants would require a completely different source of energy, such as synthetic materials or renewable energy sources such as wind or solar power, to power the skyscrapers and other technological advancements seen in these fictional depictions. However, these alternative energy sources would not be able to provide the organic compounds necessary for biological life and would have to be supplemented with other sources of nutrition and energy.
In conclusion, a world devoid of plants as depicted in many works of fiction is not possible based on our current understanding of the biosphere and energy flow in the ecosystem.

Which organisms can reproduce using the process of fragmentation
Answers
Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.
In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.
Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.
Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms, annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.
Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.
Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.
Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.
Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Answers
Anaphase occurs during the M phase (mitosis) of the cell cycle and is not represented by any of the provided options (A, B, C, or D).
Anaphase is a critical stage in cell division, specifically in mitosis or meiosis. It occurs after metaphase and before telophase. During anaphase, the sister chromatids, which are replicated chromosomes held together by a centromere, separate and move towards opposite ends of the cell.In the context of the cell cycle, anaphase takes place during mitosis. The cell cycle consists of four phases: G1 (gap 1), S (synthesis), G2 (gap 2), and M (mitosis). Mitosis is the M phase, which further consists of four stages: prophase, metaphase, anaphase, and telophase.Therefore, the correct answer is not provided in the given options. Anaphase occurs during the M phase or mitosis and is not associated with any specific phase (A, B, C, or D) mentioned in the question.
