Answer:
The flow of matter and energy among Earth's geosphere, hydrosphere, atmosphere, and biosphere involves several processes. Some of these processes include:
1. The water cycle: Water evaporates from the hydrosphere into the atmosphere, forms clouds, and then precipitates back to the Earth's surface. This process helps in the transfer of water and energy between the hydrosphere and atmosphere.
2. Nutrient cycling: Nutrients like carbon, nitrogen, and phosphorus move through the biosphere through processes like photosynthesis, respiration, decomposition, and nutrient uptake by plants. These cycles help in the transfer of matter and energy between the biosphere and geosphere.
3. Energy transfer: Solar energy is absorbed by the Earth's surface, leading to heating of the geosphere. This heat is then transferred to the atmosphere through processes like conduction, convection, and radiation. The biosphere also relies on this energy for photosynthesis and other metabolic processes.
4. Geological processes: The geosphere plays a role in the cycling of matter and energy through processes like weathering, erosion, and volcanic activity. These processes can release or store nutrients and gases, affecting the hydrosphere, atmosphere, and biosphere.
These are just a few examples of the interconnected processes that contribute to the flow of matter and energy among Earth's geosphere, hydrosphere, atmosphere, and biosphere.
Loudness of a sound relates the intensity of any given sound to the intensity at the edge of hearing.
The loudness of sound waves that are in phase will be twice as loud as they would be by themselves, if they are out of phase, a beat will be produced, or maybe a neighborhood of no sound at all.
The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the edge of hearing.
Thus, the sound waves that are in phase will be twice as loud as they would be by themselves,if they are out of phase, the beat will be produced.
To know more about the loudness of sound waves follow the link:
If all of the individual in a generation receives one dominant allele and one recessive allele, then they will all show the dominant trait.
If they are bred, they will pass on the dominant allele to some of their offspring and recessive allele to others.
If an offspring receives two recessive alleles, it will show the recessive trait and therefore it will reappear.
When two true-breeding or homozygous individuals for dominant and recessive traits are crossed, the resultant is always a dominant trait. The recessive character appears in the following generation when the F1 progeny is self-crossed due to independent segregation and random fusion of gametes.
Further Explanation:
Consider Mendel's experiment on a pea plant in which he used the trait of height as tall and short. On self-pollinating the tall plants, the resulting progeny were all tall while when self-pollination was done for short plants, the resultants were all short. It was found that when true-breeding short (t) plants are bred with the true breeding tall (T) plants, the offspring results in all tall plants in the F1 generation. When this progeny is self-crossed, the F2 generation results in both tall and short plants in a 3:1 ratio.
Mendel stated that the traits are controlled by genes that are present in pairs of alleles. Each parent contributes the alleles in the pair. Allele 'T' is received from a tall parent while short parent contributes to allele’t’ and they together produce a tall plant. This is because the 'T' allele suppresses the expression of’t’ allele because of its dominant nature. Therefore,’t’ is a recessive allele, and 'T' is a dominant allele.
Cross between true-breeding tall (TT) and short (tt) plant:
Parents: TT x tt
Gametes: T x t
Progeny: Tt (tall, F1 generation)
When F1 generation is self crossed:
Parents: Tt x Tt
Gametes: T, t x T, t
Progeny: TT, Tt, Tt, tt
In the F1 generation,the recessive trait (short plant) was suppressed because of the dominance of the 'T' allele over the’t’ allele. In the following generation, the recessive trait reappeared because of the independent segregation of gametes and their random association with each other.
