Answer:
FalseExplanation:
Meselson-stahl experiment: The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template while DNA replication for synthesis of a new, complementary strand.
The conservative model was eliminated because according to it, there would be 2 bands, one representing the parental DNA at one density and other representing the daughter DNA at a different density. The result from the Meselson–Stahl experiment after one generation was consistent with both the semi-conservative as well the dispersive model.
The data from the Meselson-Stahl experiment after one generation of replication supports the semi-conservative model rather than the dispersive model of DNA replication. The dispersive model was eliminated because it predicted a broad band of mixed light and heavy DNA, but the experiment showed a single band of hybrid DNA. The statement is true.
Explanation:The statement that the data obtained from the Meselson–Stahl experiment after one generation of replication eliminated the dispersive model of DNA replication is True.
The Meselson–Stahl experiment was designed to determine the method by which DNA replicates. It did so by incorporating Nitrogen-15, a heavy isotope of nitrogen, into DNA and then monitoring the distribution of this heavy DNA during subsequent replication cycles. After one generation of replication, the results showed a single band of hybrid DNA, refuting the dispersive model which predicted a mix of light and heavy DNA distributed throughout a broad band. This provided strong evidence for the semi-conservative model of DNA replication, in which each of the two strands of the DNA molecule serves as a template for the synthesis of a new, complementary strand.

All of the following are true of natural selection, EXCEPT A. it results in a change in allele frequencies over time. B. it works best in genetically uniform populations. C. it is the process by which evolution occurs. D. it results in some individuals surviving better and reproducing more than others. E. it results in populations better suited to their environment than their predecessors.
Answer:
B. it works best in genetically uniform populations.
Explanation:
Natural selection: The environment will determine which traits are used as and advantage to breed more successfully.
If every being of that specific species was exactly the same then natural selection would kill them all off at once.
If you had a zebra that was white and one that had stripes. the one with stripes would last longer.
It works best in genetically uniform populations is not true except natural selection.
What is natural selection?
An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
One way to explain the millions of species that have existed on Earth is through natural selection.
Natural selection results in the transmission of advantageous genetic variants through reproduction. As a result, a new generation of organisms emerges that has a higher chance of surviving and reproducing.
For instance, giraffes have an edge over other species due to their long necks, which have allowed them to graze on leaves that others cannot reach. Those with longer necks were able to grow larger because of a greater food source.
Therefore, It works best in genetically uniform populations is not true except natural selection.

In general, each species of fruit fly in the Hawaiian archipelago is restricted to a single island. One hypothesis to explain this pattern is that new species formed after a small number of flies colonized each new island. This mechanism is called:
Answer:
Geographical isolation
Explanation:
The formation of new species by a small number of fruit flies colonized each new island. This mechanism is called geographical speciation or allopatric speciation.
The geographical speciation takes place when some members (biological populations) of the same species become isolated due to geographical changes such as mountain building or migration. Due to isolation, the organisms prevents two or more groups from mating with each other on regular basis. The gene flow between them is greatly reduced which eventually causing that formation of new species.

Sickle-cell anemia is associated with a mutation in the gene encoding the beta subunit of hemoglobin that results in a change from glutamic acid to valine at position 6. All other amino acids are identical to a normal hemoglobin molecule. Based on the information above, which of the following mutations is the most likely cause of sickle-cell anemia?
a. A single base-pair substitution in the gene encoding the beta subunit.b. A single base-pair insertion in the gene encoding the beta subunitc. A single base-pair deletion in the gene encoding the beta subunit
d. A translocation of DNA from one chromosome to another
Answer:
AExplanation:
1. Sickle cell anemia is an inherited condition, disorder (disease).
2. It is a recessive condition, in which red blood cell become mutated and converted to a sickle like shape, and there aren't enough healthy red blood cells to carry oxygen throughout the body.
3. This condition normally occur when, there is inheritance of two abnormal or mutated copies of the β-globin gene, one allele from each parent.
4. β-globin gene makes haemoglobin.
5. Sickle cell anemia results when glutamic acid being substituted by valine at position 6 ( in short E6V substitution).
6. So, it a single base-pair substitution in the gene encoding the beta subunit.
"The correct option is a. A single base-pair substitution in the gene encoding the beta subunit. The most likely cause of sickle-cell anemia is a single base-pair substitution in the gene encoding the beta subunit of hemoglobin.
Sickle-cell anemia is caused by a mutation in the gene that encodes the beta subunit of hemoglobin. The mutation results in the substitution of a single amino acid, glutamic acid, with valine at position 6 in the beta-globin chain. Since glutamic acid is encoded by the codons GAA or GAG, and valine is encoded by the codons GTT, GTC, GTA, or GTG, a single base-pair change can result in this amino acid substitution.
For example, if the original codon for glutamic acid is GAG, a single base-pair substitution of A for T would change it to GTG, which codes for valine. This is a classic example of a point mutation, specifically a missense mutation, where a single nucleotide change in the DNA sequence leads to the substitution of one amino acid for another in the protein sequence.
The other options are less likely to be the cause of sickle-cell anemia:
b. A single base-pair insertion in the gene encoding the beta subunit: An insertion would shift the reading frame of the gene, leading to a completely different amino acid sequence downstream of the insertion, which is not the case in sickle-cell anemia.
c. A single base-pair deletion in the gene encoding the beta subunit: A deletion would also shift the reading frame, resulting in a nonfunctional protein or a protein with a different sequence than the one associated with sickle-cell anemia.
d. A translocation of DNA from one chromosome to another: Translocation involves the movement of large segments of DNA between chromosomes, which is not consistent with the single amino acid change observed in sickle-cell anemia.
Therefore, the most likely cause of sickle-cell anemia is a single base-pair substitution in the gene encoding the beta subunit of hemoglobin."

If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?A) Backtrack through her previous experiments to obtain another plant with the same traits.B) Breed this plant with another plant with much weaker traitsC) Clone the plant.D) Force the plant to self-pollinate to obtain an identical one
Explanation:
To clone a plant means to create an identical copy of an adult plant. These identical copies become young plants that in turn become adult plants that can be cloned again. This process can go on indefinitelyThe most common method of cloning plants and the one that has been used for a very long time is that of taking cuttings from an adult plant. A cutting is a stem or leaf that is cut from an adult plant. The cutting is then planted into moist soil or other moist growing media. The cutting will produce roots of its own and then become a whole new plant identical to the original adult plant. Not all plants can be cloned via cuttings, thoughVegetative proliferation works in light of the fact that the finish of the cutting structures a mass of non-particular cells called a callus. With karma, the callus will develop, gap and structure different specific cells (roots, and so on.), in the end framing another plantHence, the right answer is option C "Clone the plant"

The apoplast in plant tissues consists of:________. a. cell walls, extracellular spaces, and vessel elements b. cell walls, extracellular spaces, and plasmodesmata c. vessel elements, plasmodesmata, and extracellular spaces d. cell walls, plasma membrane, and cytosol
The correct answer is a. cell walls, extracellular spaces, and vessel elements.
Here's why the other options are incorrect:
* b. cell walls, extracellular spaces, and plasmodesmata: Plasmodesmata are specialized channels connecting the cytoplasm of adjacent cells, and they are considered part of the symplast, not the apoplast.
* c. vessel elements, plasmodesmata, and extracellular spaces: As mentioned above, plasmodesmata are part of the symplast. Additionally, vascular elements like xylem and phloem contain internal lumens, which are considered part of the apoplast, but not vessel elements themselves.
* d. cell walls, plasma membrane, and cytosol: The plasma membrane and cytosol are inside the plant cell, while the apoplast refers to the extracellular space outside the plasma membrane.
Therefore, the apoplast encompasses the non-living spaces outside the cell walls, including the cell walls themselves, the intercellular spaces between cells, and the internal lumens of xylem and phloem elements.
Global warming has been hypothesized to cause many plants to flower earlier. If bees search for food earlier in response to this, this would represent ________ within the community.
Coevolution
Explanation:
Coevolution is the phenomena in which two interacting species evolve under the influence of each other.
Global warming caused a drastic rise in temperature. The temperature condition during the original flowering season became higher than the optimum flowering temperature. So, the flowering plants began to flower earlier.
This created a food crisis for bees who were adapted to collect food during the flowering season. However, they evolved along with the flowering plants and started searching food earlier.
So we can say that evolution of flowering plant caused the evolution of bees.So it is a coevolution.

Maturation is the physical growth and development of the body, brain, and nervous system, marking key stages such as puberty where individuals become capable of reproduction. It's a component of lifespan development, which studies the changes from conception to death, and is influenced by both genetic and environmental factors.
Explanation:
Maturation is defined as the physical growth and development of the body, brain, and nervous system. This process encompasses the changes and growth that a person goes through, often highlighted during puberty when sexual organs mature and individuals become capable of reproduction. Maturation is an intrinsic development sequence guided by genetic factors but can be influenced by environmental factors as well. It is crucial in the context of lifespan development, which studies how individuals grow and change from conception to death. The nature versus nurture controversy further explores how both genetic predispositions (nature) and environmental influences (nurture) guide this growth and development, affecting traits such as personality, intelligence, and physical characteristics in complex ways. Understanding maturation and its role in human development provides insights into the comprehensive process of becoming mature, encompassing physical, cognitive, and psychosocial growth.

Explanation:
When protein is taken in excess amount, because it cannot be stored in the body, it can be broken down to amino acids, which is further used as carbon skeletons to synthesize fats, which is then further stored in the adipose tissues.
When the body is not receiving enough calories from other nutrient sources like carbohydrates and fats, the available protein is the used as energy to meet the body's energy demands, by converting it to fat.
Note that, excess intake of protein can be harmful to the body.
