This suggests that we are almost guaranteed to have shared a common ancestor at some point during our evolutionary development. The 2 percent variation can result in significant phenotypical differences across species (as seen between humans and chimpanzees), which indicates that our species diverged fairly recently within the evolutionary timeline.
Answer:
Some particles went through vacant regions of the atom, while others were redirected by concentrated clusters of positive charge within the atoms.
Explanation:
In Rutherford's experiment, particles either passed straight through the gold foil or were deflected by the positively charged nucleus.
This response is accurate because the particles moved through vacant regions of the atom (not just spaces among atoms), with some being deflected by zones of concentrated positive charge (the nucleus).
Answer:
1. Habitat: Histosols are found in grasslands, swamps, and marshes, while aridosols are prevalent in arid environments like deserts.
2. Appearance: Due to their richness in organic matter, Histosols are darker, while the lower organic matter content in aridosols gives them a lighter hue.
3. Water retention: Histosols can retain water more effectively than aridosols.
4. Decomposition speed: Histosols also show a higher rate of decomposition compared to aridosols.
Choice C is correct. The folding of the inner mitochondrial membrane is essential to enhance surface area for numerous protein complexes involved in the Krebs cycle during cellular respiration. One significant protein is ATP synthase, which uses potential energy harnessed during proton transport to generate ATP. A flatter inner membrane would reduce ATP synthase quantity, compromising mitochondrial efficiency and leading to fatigue during high energy demands.
Response:
Each year, the population increases by 40 squirrels.
Details:
The annual death rate is 0.02 per person, with a birth rate of 0.06. For a population of 1000, the annual deaths amount to 1000* 0.02 = 20. Conversely, the yearly births total 1000* 0.06 = 60. Therefore, the net addition to the squirrel population each year is 40.
