In your own words explain how you think that DNA, mutation, genotype, phenotype, and natural selection interconnect to cause evolution

Answers

Answer: According to sources, the most probable answer to this query is that evolution happens because when life came it sought for survival. Now, this is through mutation which causes random DNA sequences leading to genotypic and phenotypic changes. Natural selection as relation to adapting to the selection forces of the environment. And when these factors is added by the niche and other large case scenario to cause major anatomical changes, speciation comes through. And that, the process of evolution. And how it is a mechanism and an intermediate interaction with the environment.

What is the history of Gene Therapy?

Answers

Answer:

The concepts of gene therapy arose initially during the 1960s and early 1970s whilst the development of genetically marked cells lines and the clarification of mechanisms of cell transformation by the papaovaviruses polyoma and SV40 was in progress.

Explanation:

Answer:

The concept of gene therapy arose during the 1960s and 1970s and is still in its infancy, meaning there is a paucity of reliable, long-term data on the safety and efficacy of this therapy.

B) A population of mice live on the ground and in short trees. An invasive, tree-dwelling snake that preys on the mice is introduced into the area.

C) Climate change-induced warming of arctic tundra reduces average snow cover that lighter-colored arctic
foxes rely on for camouflage. Darker-colored arctic foxes are better suited to the exposed moss and grass habitat.

D) House sparrows that lay smaller-than-average clutches of eggs produce fewer viable offspring, while larger-than-average clutches of eggs result in malnourished chicks that have a higher mortality.

Answers

Answer:

C) Climate change-induced warming of arctic tundra reduces average snow cover that lighter-colored arctic foxes rely on for camouflage. Darker-colored arctic foxes are better suited to the exposed moss and grass habitat.

The graph shows how 'climate change reduces snow cover that lighter-colored arctic foxes rely on for camouflage, whereas darker arctic foxes are better suited'.

What is adaptation?

Adaptation refers to the emergence of phenotypic characteristics to face environmental factors.

Adaptations are evolutionary responses to challenging environmental conditions.

Adaptations are fundamental during environmental change (e.g., (climate change).

In conclusion, the graph shows how 'climate change reduces snow cover that lighter-colored arctic foxes rely on for camouflage, whereas darker arctic foxes are better suited'.

Describe how amino acids are categorized by their chemical properties. Explain how a change in the amino acid sequence of the FXR1 protein could decrease the ability of the protein to bind to RNA .

Answers

Answer:

The nature of amino acids can vary they can be acidic, alkaline, or neutral based on the functional group attached to their side-chain. The functional group of the amino acids determines the property of the hydro loving or phobic nature of particular amino acids. Interaction of different biomolecules depends on their affinities with one another such as hydrogen bonds, ionic bonds, van der Waals interaction based on structural and fundamental unit or monomer of the biomolecule.

Based on the given explanation, we can say that if there is a modification in the sequence of the building block amino acid of the FXR1 protein, might lead to a decrease in affinity to bind to the RNA by changing in the binding domain of this protein. There might be a complete structural change such that it can no longer interact with RNA.

Amino acids are grouped on the basis of their side chains.

Amino acids are categorized on the basis of their side chain attachment. All the amino acids has a specific side chain which is known as an R group. This R group is also attached to the α carbon. The R groups consist of shapes, sizes, charges, and reactivities. This allows all amino acids to be grouped or categorized on the basis of their chemical properties of their side chains.

If there is a change occur in the sequence of the building block amino acid of the FXR1 protein, it might lead to a decrease of binding to the RNA. There might be a complete change in the structure which leads no more attachment with RNA so we can conclude that amino acids are grouped on the basis of their side chains.

The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the ________. The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the ________. distal convoluted tubule nephron loop glomerular filtration membrane collecting duct

Answers

Answer:

The correct answer is nephron loop. The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the nephron loop.

Explanation:

The nephron loop is the portion of the nephron that follows the proximal convoluted tubule. It is located mainly in the renal medulla. Water moves by osmosis thanks to an osmotic gradient, in other words, it moves from a space with a lower concentration of solutes (hypotonic solution) to a space with a higher concentration of solutes (hypertonic solution) to try to dissolve it. Among the functions of the nephron loop is the creation of the medullary osmotic gradient by the countercurrent multiplier mechanism. Osmolarity is an intensive property that requires one or more "sources" of osmoles, capable of creating a gradient. In the nephron loop there are several sources of this type: a) the system that transports NaCl in the thick portion of the ascending limb b) the passive Na + outflow from the thin portion of the ascending limb c) the Na + outflow and of urea from the collector.

He closed all banks for four days in order to check their health and restore consumer confidence, and he worked with Congress to pass legislation that protected deposits and gave the Fed greater regulatory power.
