What are possible origins of Earth's surface and internal energy?

Biology
1 answer:
saul85 [17]3 years ago
3 0

Answer:

The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.

Two true-breeding stocks of pea plants are crossed. one parent has red, axial flowers and theother has white, terminal flowers;
xxTIMURxx [149]
This is a typical case of a dihybrid cross. 
From the phenotype of the offspring, we can conclude that the gene for the red color of the flower and the gene for the axial position of the flower are dominant.
Since we know that the ratio of phenotypes in a dihybrid cross of independently inherited alleles is
9(dominant for both traits)
3(dominant for one trait, recessive for the other)
3(dominant for the second trait, recessive for the other)
1(recessive for both traits)
we can expect 3/16 of the f2 generation to be dominamt for one trait and recessive for the other (red, terminal flowers), or to be precise 190 individuals.

compare and contrast the processes of photosynthesis and aerobic respiration. how are they similar and how do they differ?
Brut [27]

Answer:

Explanation:

Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.

Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.

6CO2 + 6H20 --------> C6H12O6 + 6O2

Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.

C6H12O6 + 6O2 ------> 6C02 + 6H2O

One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.

The highest level of Bloom's taxonomy is __________, which is defined as using your ability to judge the value of ideas and info
Kobotan [32]

Answer:

Evaluation.

Explanation:

The evaluation stage in Bloom's Taxonomy is where students make a judgment about the importance of concepts, objects, materials and more. Knowledge, comprehension, implementation, examination, synthesis, and evaluation were the main sequence of cognitive skills. Evaluation is the final stage of Bloom's pyramid taxonomy. It is at this stage that students are expected to put together all they have learned to make content assessments. However, it should be noted here that in 2001, synthesis has been removed and creation is added as the highest stage of Bloom's taxonomy.
