The C option is Correct.
- All the Galapagos finches exist on the same island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
Answer: The correct answer to the question is option 2
If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.
Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.
Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.
Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.
This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.
Establish a hyperosmotic interstitial medullary concentration
B.
The Radio-ulna and digits of most primates and animals represents a homologous structure
An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>
Answer:
<u>Fertilizer usage is linked to the agricultural practice</u> with an aim to <u>enhance the crop yield</u>. Inadequae use of fertilizers however causes soil degradation because <u>these practices overlook the spatial differences in soil fertility status </u>in agricultrual systems. Specifically,<u> not all soils require fertilizer application at the same levels</u>. A recommended approach is that, initially, there should be a proper study of limited nutrients in the soil and thereon only those nutrients should be given at controlled concentrations, which are limited. A major reason is that <u>high concentration of specific nutrients would affect the bioavailability of other nutrients</u> in the long run and could also lead to soil degradation (by affecting soil health status). <u>The microbial population in the soil could also change</u> that are typical for essential biogeochemical cycles. This is a very critical aspect in future future agriculture and to preserve the environment. <u>Deforestation</u> is a condition when the plants are cut excessively for agricultural purposes. <u>If soil degradation continues as discussed above, it would put a reduce the overall proportion of agricultrual land and cutting of naturally grown forests would be required. This would turn the green zones into agricultural zones (in future)</u>. This is a pressure on ecosystem and the consequences can be really harsh.
