balu736 [363]

Answer:

The correct answer is option A) "Sequence of bases".

Explanation:

Even though DNA most of the time is comprised entirely of only four different nucleotide bases (adenine, thymine, guanosine and citosine), it is the sequence of these bases that allows DNA to carry a vast amount of hereditary information. The genes that carry the hereditary information are translated according to the sequence of the DNA bases. The information is translated by triplets of bases (codons) that correspond to different amino acids that are added to new synthesized proteins during translation.

What can you determine from the principles of cross-cutting relationships?
Vaselesa [24]

Answer:

B.  Layers that cut across the most other features are youngest.

Explanation:

Using the principles of cross-cutting relationships, you can determine the relative age of rocks found in the ground. The idea behind it is that the geologic feature which cuts another is the younger of the two features, and it had been around for 400 years. It's not very precise but it is good for determining relative age.

What did Allan Savory notice about the lands grazed by wild animals at the Africa Centre for Holistic Management
Shkiper50 [21]

Answer:

Allan Savory noticed that grasslands co-evolved with large numbers of migrating ruminants, and therefore are co-dependent on each other's survival. These animals grouped together and constantly bunched due to the predator-prey connection, eat the grasses following the seasons throughout their migration in arid regions (Brittleness scale, of Non-Brittle to Brittle environments).

As they move, they drop nutrient-rich dung and urine, while trampling organic litter (live or dead grasses, leaves, etc) and seeds into the soil. These actions break down materials into the surface, providing more covered soil and keeping materials from chemically decomposing (oxidation, as opposed to the fast biological decomposition that occurs in areas with consistent rainfall(Non-Brittle)). The true testament to his insights of Holistic Management re: grasslands is known as the 4th Key Insight: That time, rather than numbers governs over-grazing or over-trampling.

The important component here is that the time exposed to these animals plays the significant role in whether you have healthy grasslands, not the number of animals exposed to the area of consideration. The amount of "rest" (time) for grasses between eating or trampling is just as crucial as the time in an exposure.

Explanation:

Explained in his book and courses under "Holistic Management", by Allan Savory and Jody Butterfield, and Sam Bingham
