Answer;
Adaptive radiation;
The pattern of evolution that is shown by many species of finches on the Galapagos Islands is Adaptive radiation.
Explanation;
Adaptive radiation is a pattern of evolution in which a single lineage undergoes multiple speciation events to fill divergent ecological niches. The result is a cluster of phenotypically distinct related species.
A few million years ago, one species of finch migrated to the rocky Galapagos from mainland of Central or south America. From this one migrant species would come many species;-at least 13 species of finch, which exploit different niches, evolving from a single ancestor.
<span>Phosphorus cycles between living things and the environment, particularly the soil. This is the case with many other substances as well such as carbon. The cycling occurs due to the action of organisms which uptake and release phosphorus into the soil. Phosphorus exists in animals in many forms, particularly in the ATP molecule. When the animal dies, its remains are decomposed and the constituent ions are released into the soil, after which they are taken up by plants. Animals consuming these plants gain the phosphorus again, and the cycle continues.</span>
The sun is extraordinarily hot because it is a star. Additionally, each star has its own unique, incredibly hot processes. These reactions are referred to as thermonuclear fusion. The Sun appears to be enormous in comparison to other stars due of its proximity to us. The Sun is a star of medium size. For instance, the following is a list of some of the biggest stars in our galaxy and their distance from the Sun: Mu Cephi is approximately 1500 times the diameter of our sun. The sun's core is so heated and pressurized that nuclear fusion occurs, converting hydrogen to helium. Nuclear fusion generates energy in the form of heat and photons (light)... Solar heat and light are sufficient to illuminate Earth's days and keep our planet warm enough to support life.
The answer is sun exposure .................
Answer:
A. A 300 Å fiber with 6 nucleosomes per turn is visible using electron microscopy.
C. Using electron microscopy, nucleosomes appear like beads with a diameter of 100 Å.
E. Loops of chromatin are visible using electron microscopy.
Explanation:
The nucleosomes are the key subunits of the chromatin, and they consist of two turns of DNA wrapped around a set of two copies each of the H2A, H2B, H3, and H4 histone proteins (i.e. an octamer of histones), which are connected by linear DNA and H1 histones. A zig-zag array of the nucleosomes form a 100 Angstrom (10-nm) nucleosome fiber. Subsequently, multiple histones are packaged into a 30-nanometer (300 Angstrom) fiber named solenoid. The chromatin loops are finally condensed into higher-order structures, which form chromosome sections (300 nm) and chromosome arms (700 nm), respectively.
