Albedo is the fraction of incoming light that is reflected by a celestial object. how would you predict a decrease in paved surf
iren [92.7K]

A decrease in the paved surfaces on earth will increase amount of light reflected or increase albedo.

<h3 /><h3>What is a paved surface?</h3>

A paved Surface refers to a surface covered by concrete, asphalt, masonry, or a similar material.

Paved surfaces have low albedo, that is they have low light reflectivity.

<h3>What is the effect of paved surface of Earth on albedo?</h3>

Since paved surfaces have low albedo, a decrease in the paved surfaces on earth will increase amount of light reflected (albedo).

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

How many genes found on the y chromosome trigger the testes to produce testosterone?
ahrayia [7]

The Y chromosome likely contains 70 to 200 genes that provide instructions for making proteins. Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and development.

<h3>What is a chromosome?</h3>

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule. These chromosomes exhibit a complicated three-dimensional structure that is crucial for controlling transcription.

Under a light microscope, chromosomes are typically only discernible during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form).

Prior to this, each chromosome undergoes a process known as chromosome duplication (S phase), during which a centromere connects both copies, forming either the X-shaped structure  (if the centromere is situated equatorially) or a two-arm structure (if it is situated distally) depending on where it is situated.
