Answer:

what effects do the pH has on different conditions of weather

Explanation:

ketp constant is the temperature....independent variable is time

Acid rain can have a pH between 1.5 and 5.0. The effect of acid rain on the environment depends on the pH of the rain and the characteristics of the environment. It appears that acid rain has a negative effect on plants.

Acid rain does not directly harm the human body, but the resulting sulfur dioxide can cause health problems. In particular, sulfur dioxide particles in the air can promote chronic lung problems such as asthma and bronchitis.

Acid rain or acid deposit is a broad term that includes all forms of precipitation, including acidic components such as sulfuric acid and nitric acid, falling from the atmosphere into the ground in a moist or dry form. This can be rain, snow, fog, hail, and even acidic dust.

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.

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.

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.

Answer:

atmosphere, underground, glaciers , Oceans.

water that falls from the clouds towards the ground like rain or snow or sleet

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

Evapotranspiration is the sum of water evaporation and transpiration from a surface area to the atmosphere.

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.

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.

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'.

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

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'.
