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 .
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.

________ thousands of tiny projections that add even more surface area to villi
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.

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

Reproductive barriers block gene flow between different species. Gene flow between populations tends to hold the gene pool of a species together.
Part A - Comparing species definitions
Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept.
Drag each characteristic to the appropriate bin based on the species concept(s) to which it applies → You will find this in the attached files
Answer:
Not applicable for extinct species → Biological Based on evolutionary history → Phylogenetic Relies on similarities in structure → Morphological Accommodates asexual reproduction / Species acceptance criteria can be subjective → Morphological and PhylogeneticUsed by scientists in classification → Morphological, Phylogenetic, and BiologicalExplanation:
The biological concept states that species are population groups that -in a real or potential way- can mate and reproduce, but are reproductively isolated from other groups.
Individuals belonging to a species cannot reproduce with members of other species.
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate concerning hybridization zones, something to be expected considering evolutionary processes. This is the reason why it has been less accepted by botanists, as some plant species hybridize with other species.
The phylogenetic species concept defines species on a determined time and through time, and these are the horizontal and vertical species concepts, respectively. The species group is considered to be the less inclusive monophyletic group.
According to the phylogenetic concept, a species is a monophyletic group whose organisms share synapomorphies.
The establishment of species relies on molecular markers.
The morphological species concept defines species according to the shared morphological characteristics shared by all the members of the species. It is a descriptive method to separate species.
When a group differs considerably at a morphological level from another group, it is defined as a different species.
Some limitations might emerge from this species concept. It does not consider variability among individuals,
Individuals of the same species might be polymorphic, exhibiting morphological differences between organisms. These individuals would be considered to be different species following the morphological concept. Some different species might be morphologically similar, despite being different. These species might be considered as one following the morphological concept.HELPPP DUE IN 20 MINUTES!!!!!!!

For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

Answer:
''Protect the soil is to protect life on earth'' and ''Protect the soil to ensure human survival'' .
Explanation:
''Protect the soil is to protect life on earth'' and ''Protect the soil to ensure human survival'' are the slogans to create awareness on conservation of soil. In these slogans, a very important message is given to the people is that soil is important for the survival of humans and other creatures on this planet because this soil provides food which is the main source of survival. If there is no soil , no food will be produced which leads to the death and extinction of all humans.
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
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.
